Many owners of the domestic Lada Priora car are extremely concerned about the issue of valve bending. The upcoming publication is intended to dispel doubts. Also, from the information offered, you can glean very useful information about the technical characteristics and main problems of the engines that manufacturers equip these machines with.
Motor 126 and 127: working life, differences
These engines on Priora had a displacement of 1.6 liters (or 1596 cm3). Optimal for city sedans, the engine size of the Lada Priora gave a good combination of dynamics and consumption: along with very decent acceleration, fuel consumption does not exceed sky-high numbers. Both engines received good marks, because the car behaved perfectly in the city and on the highway.
127 motor - looks like this
In fact, the 126 Priora engine became the first sixteen-valve engine for this model, and the 127 is a modified version, “overclocked” by AvtoVAZ designers. In addition to the same engine displacement, they have other identical characteristics. The in-line type of arrangement of four cylinders provides a simplified design that can be repaired on your own.
The distributed multipoint injection system is involved in creating a good, rich fuel-air mixture (a lean mixture can lead to breakdowns). The cylinder diameter is 82 mm, the piston stroke is 75.6 mm, the compression ratio is 11. The “engines” fall under the Euro 4 standard, they are powered by gasoline with an octane rating of 95.
The 126 engine for the Priora received the following characteristics: 98 hp. (72 kW at 5600 rpm), acceleration to 100 km/h in 11.5 seconds (with manual transmission), city consumption 9.1 l - 100 km (manual transmission), maximum torque - 145 Nm.
The 127 engine for the Priora was upgraded to the following figures: 106 hp. (78 kW at 5800 rpm), acceleration to 100 km/h in 11.5 seconds (with manual transmission), city consumption 8.9 liters per 100 km (with manual transmission), maximum torque – 148 Nm.
The difference may not seem so noticeable, but this is a very small but strong step in design on the part of AvtoVAZ (this is where the change to sixteen-valve “engines” with a volume of 1.6 liters ended). For a car of the Lada Priora class, the engine power was sufficient.
In the same block it is necessary to say about the operating temperature. An absolutely normal operating temperature is considered to be between 90 and 95 degrees Celsius. Further, when the car is being pushed in a traffic jam, is basking in the sun, or for some other reason, but can still work - from 97 to 110 degrees. The engine is slow in places and wears out a lot, but you can still get to your destination. A temperature below 90 degrees is a direct sign indicating that the car has not yet warmed up, and it is better to wait in place until the arrow points to the coveted 80-90 mark.
Operating a car at temperatures above 110 degrees is dangerous because the service life of the engine is noticeably reduced - hot parts undergo very severe wear, overcoming the force of friction.
In general, the service life of the Lada Priora engine with a normal driving style and careful treatment is 200,000 km - after this mark the time comes when the “engine” requires major repairs. AvtoVAZ mentioned the timing belt separately as a recommendation, saying that it needs to be checked every 100,000 km (many car enthusiasts talk about the figure of 50,000 km).
All Lada engines have a problem, and it is related to the valves, which will be discussed further.
Why do I consider the 8-valve engine on the Prior and Grant to be the best, and not the 16-valve one?
I have already written 2 articles on my channel about how I bought a Priora in May 2020, and how I serviced it first. And I want to remind you that I bought it with an 8-valve engine. And if at first I was upset, then after half a year of driving I made certain conclusions.
Valve bend
I would like to clarify that Priors are equipped with a Grant engine, and the valves bend on it! Therefore, it is necessary to monitor the belt and not bring it to a deplorable state.
Manufacturers write that it needs to be changed once every 60 thousand, but I will change it once every 30,000 kilometers. 3500 rubles, and you are calm!
This engine is not inferior to the 16-valve
This engine is a beast! If at first it may seem like, “ Where will he go? it is a toy!
". Having ridden it for half a year both in summer and winter, I want to say with confidence that this is just a beast!
This engine is revvy, it pulls well at the bottom. And the gear, in turn, rides better on top. From the start, the “octagon” can beat the “shesnar” very easily, we did the races with a friend.
Peak acceleration is from 2 to 4 thousand revolutions (this is according to my feelings).
My friend accelerated his Priora to a maximum of 207 km/h
(he has a Gamma dashboard, it shows the speed even after 200).
I accelerated my car on the road from Moscow to a maximum of 195 km/h
. I would never have thought in my life that an 8-valve engine could show such numbers.
Easy to maintain
When selling the car, the former owner told me: “ If you lose even a gram of oil in the first week of driving, I’ll give you your money back!”
“And this could be considered a phrase to specifically sell. But! I have already driven 16 thousand kilometers in 9 months, and I have never added oil (only changed it)!
I’ll say even more, no matter how much I turn the engine to the cutoff in 1-3 gears
, he just doesn't eat butter!
The last 8 thousand from the maximum level on the probe, the level decreased by 1/5 of the level (20%)
.
On Shesnar, my friends add 3 liters per 10 thousand
. Also, the hydraulics are constantly knocking, you need to change the rings with caps.
On the 8-bug I changed the oil, changed the spark plugs and moved on!
In terms of fuel consumption, I can say that on average my Priora consumes 7-8 liters of gasoline in the summer (I fill up with G-Drive at Gazprom), my friends have the same consumption with 16-valve engines.
And I don’t understand why many “clean guys” don’t like priors and grants with this engine! It pulls, it's simple, it doesn't eat oil, it doesn't cause problems!
And when buying an AvtoVAZ, I recommend paying attention to this engine! The car is cheaper, but the ride will be the same!

Recommendations for improvement
For the first time, they decided to increase the power of the new Priora 21126 engine at the factory in order to create a sports modification of it. Camshafts with increased lift, a lightweight connecting rod and piston group were installed, and the intake and exhaust tracts were modified. This is how the first domestic sports unit appeared, which was put into production, and they began to install it on the Lada Granta Sport model.
The technical characteristics of the engine are as follows: engine power from the Priora has increased to 118 hp. torque - up to 154 Nm at 4700 rpm, fuel consumption also increased to 7.8 liters per 100 km with a combined driving cycle. We will give a number of recommendations on how to independently increase the power of Priora engines:
- The simplest and most affordable way is to install a zero-resistance exhaust tract. The essence of its work is to reduce the resistance of the path, as a result of which some of the power spent on overcoming this resistance will be released and become useful.
- The same operating principle applies to the zero-resistance intake tract. Installing the receiver and throttle valve to 56 mm will allow the power unit to “breathe” more freely, and your Lada Priora will become several horsepower more powerful.
- Deeper tuning - new camshafts with a sports configuration, allowing the intake and exhaust valves to open more. This will give a noticeable increase in the agility of the car, especially in city conditions.
- Replacing the standard valves and connecting rod-piston group with a lightweight one will again release some of the useful energy of the unit and add it to the main power. Here you can kill two birds with one stone: install pistons with recesses, thereby eliminating the possibility of them “meeting” with the valves when the timing belt breaks.
- We should not forget about CHIP tuning. After major changes in the engine configuration, its operating mode will definitely improve, and in order to optimize it and adjust fuel consumption, you need to do a flashing.
Recommendations are given taking into account that the power plant is in good technical condition. If this is not the case, when tuning it is worth replacing worn parts and oil in order to get the desired effect from the changes. As a result of the above measures, the Lada Priora will receive an additional 20-30 hp. without reducing the resource.
How many horses can Priora have in addition to this? Quite a lot, there are capabilities and components to increase the power ultimately to 400 hp. This is due to a radical modification of the power plant: boring the cylinders, grinding the cylinder head, replacing the injectors and fuel pump with more efficient ones, installing four throttle valves and a turbocharger.
We should not forget about modernizing the brake system. Such tuning will give excellent results in terms of power, but the engine life will be significantly reduced, and fuel consumption, on the contrary, will increase significantly.
Sores
Of course, Priora has sores, which you just need to be attentive to and always have a certain amount of rubles in case of “exacerbation”.
- The most common is rust . More often, wheel arches, fender liner attachment points, and the bottom of doors (hidden cavities) are subject to corrosion. Rust appears on the roof, closer to the windshield, and on the hood, near the washer nozzles. To prevent rust from spreading throughout the car, treat the stains with anti-corrosion mastic.
- Over time, the gearbox to crunch when changing gears . The reason is weak synchronizers. The crunching often disappears as suddenly as it appeared, but it is better to contact a car mechanic. Due to the unreliability of the box, the shaft may burst, causing the gearbox to simply break. Repair and a new box will cost 40-50 thousand rubles. Some car owners, to prevent the problem from recurring, install boxes from other VAZ models, for example, VAZ-2115.
- Priora's problem number three is the immobilizer . Over time, it stops working completely, because... What comes from the factory is simply cheap, Chinese. The owners repair it or solder it, do chip tuning. The asking price is 2-3 thousand rubles. If the Priora you are interested in has not yet encountered this problem, get ready.
- 8 out of 10 Prior owners have already changed brake hoses, clutch and heating system hoses . Keep these elements under control, otherwise serious repairs will not be avoided. The asking price is 5-6 thousand rubles.
- is often covered . Moreover, in which mode it breaks down, in this mode the headlights continue to burn. Those. if you were driving on the highway with high beams and the unit breaks, the light will remain on even when you turn off the car. Fortunately, you can change it easily and quickly, even with skillful hands you can do it yourself. The cost of the element is 1-1.5 thousand rubles.
- Another problem that “pops up” in 9 out of 10 Priors is the “guzzling” of oil . When it appears depends on operating conditions and mileage. Moreover, the spark plugs and exhaust pipe will remain clean and there will be no leaks. Experienced car owners advise that if there is a fantastic loss of oil, go to a mechanic as soon as possible. Most likely, you will have to repair the cylinder head, which will cost 20-30 thousand rubles.
The set of problems is quite large, and many are expensive to eliminate. But keep in mind: similar procedures with a more or less budget foreign car would cost 1.5-2 times more.
Engine test tables and graphs
As you can see from the table, the power of the 1.8-liter engine has a positive effect on its dynamics and even consumption. It would seem that it is fuel consumption that should increase, but test results prove the opposite.
Engine power
In this graph, the favorite is immediately visible; there are practically no equal to the 1.8-liter engine.
Regular diagnostics are the key to long engine operation
In addition to all of the above, regular diagnostics also help to increase the service life of the motor. The engine on a Priora can experience enormous loads if any of the systems are not working correctly. For example, if fuel equipment breaks down or there are malfunctions in the ignition system, the cylinders may periodically turn off, which will negatively affect the durability of the piston group. Failure of sensors also leads to certain problems in the engine operating mode. By identifying a diagnostic failure in time and promptly eliminating it, the motor can be returned to normal and the negative impact of the breakdown can be reduced.
If you regularly inspect the Priora engine, it is quite possible to prevent many serious problems. It is worth remembering that repairing fuel equipment or ignition is much easier than doing a major overhaul of the engine. Plus, interfering directly with the engine itself usually reduces its resource. If the old Zhiguli models were assembled by hand, the Lada Priora is made mainly by robots, so when repairing the engine, the factory precision of the assembly can be disrupted. Because of this, backlash may begin to form in the parts, as a result of which they will begin to wear out faster. And how much horsepower can you lose if you do a major overhaul! In short, it’s better not to get into the engine.

General characteristics
Initially, the car was equipped with an 8-valve engine from the VAZ 2114, about which car enthusiasts in practice know all the characteristics, in particular, what kind of service life it has in different modes. Therefore, the first “Priors” did not receive rave reviews from customers.
Subsequently, the car was equipped with its own 16-valve unit modification 21126 with a displacement of 1.6 liters and a power of 98 horsepower, which made the VAZ 2170 truly competitive. Dynamic performance has been improved, emissions into the environment and fuel consumption have been reduced. Relatively recently, an updated version of the 21127 engine with a power of 106 hp appeared. which has been installed on Priora since 2013. Comparative characteristics of all three units are given in Table 1.

Updated power plants
At the very beginning, this car was heavily criticized, especially for the old “ten” 8-valve engine. However, very soon they began to install a new engine with 16 valves on the car, which amazed the new owners with its qualities. If you look at its technical characteristics, you won’t notice much difference with the old motor. Yes, fuel consumption was reduced by about 1 liter and by 10 liters. With. The power increased, but this did not have much effect on the dynamics. The maximum speed, although increased, was only 20 km/h. The most important thing is that the engine runs much quieter. This is immediately felt by both the driver and passengers - associations arise with high-quality modern foreign cars. Therefore, how many horses Priora has is not a fundamental question.
The second very important point is that the engine operates smoothly throughout the entire speed segment. If the “ten” required some getting used to from the driver, for example, he had to constantly glance at the tachometer and listen to the engine, then the “Lada Priora” allows you to drive without the slightest stress. It was possible to improve the engine performance of the Priora not only through a new gas distribution system, but also through the use of updated pistons, connecting rods and a number of other parts.
In addition to the basic 16-valve engine, other engines are also installed on the Priora. In particular, there is a version of the VAZ-21127, which features a modified intake manifold. How many more “horses” did this add? Only about 8, the total engine power of the model was 106 hp. With. Also among the Priora engines there is a version of the VAZ-21128, which is manufactured by one of the tuning companies. Its power has been increased to 120 hp. With. In general, the units are almost identical to each other both in design and in service life. Therefore, their reliability is approximately the same.
But the build quality of the motors is very different. Moreover, the power plant itself is usually assembled quite well, but the attachments are rather weak. Almost everyone knows what problem areas the engine has. For example, a pump often fails. Early models of the car had problems with the timing pulley until it was replaced with a Gates branded one. Despite the presence of shortcomings, the car does not cause much trouble.
Updates and shortcomings
The table clearly shows how many horses the Priora had with the old power plant and how the power and torque changed as the update progressed. Here is a description of how the design features of the new units changed compared to the old ones:
- The number of valves has increased, there are 4 of them for each cylinder. It's no secret what a positive impact this factor has on engine performance. The filling of the cylinder with the combustible mixture improves, the chamber is qualitatively emptied of combustion products (exhaust gases), the operation of the unit becomes more stable, power increases while fuel consumption decreases.
- The compression ratio is increased by increasing the piston stroke. The new engine 21126 and 21127 now uses gasoline with a higher octane number, but at the same time the efficiency of fuel combustion increases, which has a positive effect on power. It’s impossible not to notice how the working volume of the Priora’s engine has increased thanks to the increased piston stroke.
- In modification 21127, compared to 21126, the intake manifold was modified. How this affected the engine performance of the Priora can be seen in the table. Power increased by 8 hp. in addition, performance at low and medium speeds has improved.
- The new engines on the Priora have better environmental performance and lower fuel consumption. This was achieved through such improvements as modernizing the crankcase ventilation system and reducing the weight of the piston group. Now crankcase gases are burned more intensively in the cylinders and the emission of harmful substances into the atmosphere has decreased.
- Over the many years of operation of VAZ vehicles, a definite opinion has developed that the power units of Zhiguli cars do not last 150 thousand km until they are overhauled. Now, due to the use of new, higher quality components, the engine life has increased to at least 200 thousand km.
Despite the fact that the updated Priora engine is almost the most advanced domestic unit, it has its drawbacks. For example, when a timing belt breaks, the valves inevitably collide with the pistons and bend - this is its most serious drawback. How to eliminate it without waiting for trouble? It is necessary to replace the standard pistons with new ones, with special selections for the valves.
The remaining shortcomings are not so significant and they are usually associated with some kind of defect that can still be found on domestic cars. This could be increased noise from the operation of hydraulic compensators (often found on VAZ cars), an unexpectedly burnt gasket under the cylinder head, or floating idle speed. Or some unit of the attached equipment fails:
- a drop in fuel pressure in the system leads to difficulty starting the Priora engine and loss of its power;
- sensor malfunctions;
- air leaks in the fuel tract through the pipes;
- problems with the injector throttle valve.
What kind of mileage can the Priorovsky engine withstand?
Taking into account many factors, the mileage and actual service life of VAZ 21126 engines may vary greatly. There have been many cases when, after 40 thousand kilometers, an almost new car had a problem with oil consumption, more than 1 liter per 1000 km, which is unacceptable.
After opening the engines, it turned out that the pistons in the cylinders not only had different groups from A to C, but in the literal sense of the word they were practically hanging out in the block. This is why many people experience a strange sound when running a cold engine, somewhat similar to the operation of a diesel engine.
But it is also worth noting that there are many more cases with a really high resource. For example, the average mileage of engines sent for repair at Priors exceeds 200 thousand kilometers. Of course, this cannot be considered a benchmark, but it is quite a good resource for a VAZ engine. There are many cars with mileage of under 400 and even 500 thousand that have never been repaired during these miles. In this case, most likely the engine is already reaching its end, consuming oil and gasoline, pulling poorly, etc. but nevertheless, this suggests that if you are lucky, and in addition you carefully operated the car, then you can achieve similar results.

Each power unit has a certain period of operation without significant intervention in its design, this is the so-called engine resource. This concept applies to all power units, including the Priora engine.
Engine life depends on many factors. Any motor, even without partial intervention, will work for a short period of time. To extend its life, periodic replacement of working fluids and elements is required, which, due to their load, wear out very quickly. Popularly, operations to replace fluids and wearable items are called “replacing consumables.”
The engines that are installed on Priora are considered a new generation of power units mounted on domestic cars. A feature of the first units installed on Priora, in contrast to subsequent generations, was that they had 2 valves for each cylinder. Subsequent engines were already equipped with 4 valves for each cylinder. Each of these engines has certain operating and maintenance conditions.
How much does engine 126 and 127 cost?
Engine 126 has catalog number 21126100026030, sells for about 107,000 rubles, engine 127, respectively, has catalog number 21127100026030, its price is slightly higher by 3-5 thousand rubles. The price on the secondary market will be significantly lower (up to 20-25 thousand rubles), but the savings will not pay off - a used “engine” can last no more than 1000 km, this is a real lottery.
How to find out what engine is in a Priora
You can find out by looking at the plate on the left glass of the rack, where the engine number is written on the edge. From it you can understand the 8-valve unit, or 16. You can also recognize the modification 21126 or 21127.
Problem areas of the engine
During operation, Priora owners identified several weaknesses in the engine:
| Weakness | Description |
| Liquid pump (pump) | Often this element fails. And if the driver did not pay attention to the temperature sensor readings in time, pump failure will lead to serious consequences. The power plant will quickly overheat and jam. To bring it back into working order later, you will have to grind the cylinders and replace the piston group. |
| Radiator | Leaks often appear at joints and should be repaired immediately. |
| Timing belt tensioner roller | If, while the Priora engine is running, a hum appears under the hood in the area of the timing belt cover, action should be taken immediately. If the hum appears during a long trip, you can restore the performance of the roller by generously lubricating it. But this won’t help for long; the video will still have to be changed. |
If you ignore the hum, this will lead to the fact that, due to the increased load, the timing belt will fly off or break. The consequence of this will be bent valves and major engine repairs.
Often, Priora owners complain about oil leaking from under the valve cover. This problem can be resolved by replacing the cover gasket.
Signs of the need for internal combustion engine repair
The reasons why the operation of the engine is disrupted are arranged in a small list, starting with refusal to start and ending with floating idle speed (this problem was removed on the 127 “engine”). Not all breakdowns end in capital damage - sometimes it’s enough to add oil, sometimes it’s enough to adjust the ECU settings.
Compression reduction
A decrease in cylinder compression below 16 atmospheres is a bad sign. Such a high limit corresponds to a compression ratio of 11.
If the compression decreases (or vice versa increases), then the “engine” will have to be rebuilt.
Knocks in the engine
Engine knocks can come from several points. These could be hydraulic compressors, timing belt rollers or pins. The knocking noise could also be caused by low oil level. The answer to the question will be given by a thorough detailed inspection of all parts of the unit and checking the oil level.
Blue smoke from the exhaust pipe
The blue smoke that comes from the exhaust pipe appears when oil enters the combustion chamber. It can leak either from the valves or from under the piston. The result is the same: the oil is eaten up and blue smoke pours out of the chimney. Once the leak is located, half the problem will already be solved.
Troit motor
Sometimes in the cold the engine may stall - don’t be alarmed by this, because it may simply be one of the spark plugs that fails. In this case, we advise you to simply restart the engine and it will stop running.
Electrics
Be prepared for the fact that you will have to frequently change the headlight and low beam bulbs. The windshield wiper switch will malfunction and the windows will not go up.
The factory alarm often malfunctions: it goes off falsely, refuses to close or open doors. The problem can only be corrected by installing a new system. The price of such pleasure is 10-30 thousand rubles (if with auto start, then more expensive).
The electric power steering often malfunctions - it turns hard, the steering wheel has to be pushed, or it jerks on its own. Usually the previous owner will fix this problem under warranty. If he didn’t do this, get ready to pay at least 10-15 thousand rubles to car mechanics. Or try cleaning the contacts or changing the speed sensor.
The heating system may also fail if this has not happened before. The price of spare parts is from 1 to 1.5 thousand, repairs are another 1000 rubles.
Engine
Lada Priora has undergone changes several times, both externally and technically. The appearance, power plant and transmission changed.
Below is an example of engines that were installed on the VAZ 2170-72.
Engine 21116 (8 valves)
This engine was installed on the VAZ 2114 and Lada Kalina, and was later inherited by the Priora. The power of this internal combustion engine is 80 hp. with a volume of 1.6 liters, which is very small. Such an engine does not have good dynamics, and it is difficult for it to “drag” the body of the Priora.
Pros:
- Does not bend valves;
- Easy to maintain;
- Cheaper spare parts;
Minuses:
- Low power;
- Noisiness;
The installation of such an engine continued until 2022.
Engine 21126 (16 valves)
16 valve engine with more power and torque compared to 116. It is a modified model of the 124 engine. Its power is 98 hp. with a volume of 1.6 liters.
Pros:
- Great power;
- No noisy operation;
Minuses:
- Bend valves when the belt breaks;
- Expensive spare parts;
Engine 21127 (16 valves)
The modified 126 engine received the index 21127; the intake in this engine was changed, thereby increasing the power to 106 hp. with the same volume of 1.6 liters. They began to install a new cable gearbox for this engine.
Pros:
- High power;
- No noisy operation;
Minuses:
- Bend valves;
- Expensive spare parts;
Engine 21128 (16 valves)
This engine was specially designed for more powerful Lada cars with the “Super Auto” nameplate. The power of this engine has increased, as has its volume. The number of horsepower in the super car engine increased to 123, and the volume to 1.8 liters, which radically affected the dynamics of the car.
Pros:
- Good dynamics and high power;
Minuses:
- Bend valves;
- More expensive spare parts;

The 6-liter
engine of the
21116
is essentially an updated version of the
VAZ 21114
only with a lightweight connecting rod and piston group developed by the American company
Federal Mogul
. It was in 2011 that AvtoVAZ began installing the most popular updated 8-valve power unit on its cars, which received about 60% of imported components.
So, in the
21116
, the engineers completely replaced the standard connecting rod and piston group with a lightweight imported one, modified the cooling system of the entire power unit, equipped the piston skirts with special anti-friction inserts and installed cooling oil nozzles. In addition, the new internal combustion engine now has both intake and exhaust manifolds.
However, there were no nuances for car owners when developing a new engine.
The fact is that the pistons with which the internal combustion engine in question is equipped do not have special holes on the bottom; if the timing belt
breaks, the valves inevitably bend, although the gas distribution mechanism of the power plant was seriously redesigned towards strengthening, the problem was not completely solved.
To prevent premature breakage of the belt drive, the manufacturer decided to install an automatic tensioner and a fairly durable timing belt from Gates
, the declared service life of which is 190-200 thousand kilometers before replacement.
In general, the VAZ engine is no matter what it is.
The functions of the load-bearing part of the power plant are performed by a block designed for an in-line arrangement of four cylinders, cast from cast iron and an aluminum head for 8 valves with an overhead camshaft. In the engine under review, the valves are driven by cams using pushers. As for hydraulic compensators, they are not provided here, so the car owner has to periodically adjust the valve clearances ( approximately once every 45-50 thousand kilometers
).

In turn, other owners criticize this engine for frequent adjustment of valve clearances and regular problems with frequent use. However, according to auto mechanics, the use of a number of imported components in the creation of internal combustion engines has significantly increased the overall reliability of the power unit.

In the vast majority of cases, overheating or underheating of the VAZ power unit occurs due to an unfinished thermostat and cooling system fan. As a rule, after the fan and thermostat fail, antifreeze leaks appear in the system, as a result of which the engine is not able to heat up properly in cold weather, and on the contrary, it often overheats in warm weather. 5

As auto mechanics recommend, it is better to change the engine oil in a VAZ engine every 9-10 thousand kilometers, and not 15 thousand kilometers, as prescribed by the manufacturer. To change the engine oil yourself, you need to stock up on about 3.5 liters of high-quality semi-synthetic (5W30, 5W40, 10W40 or 15W40), and you also need to buy a good oil filter.

Where is the engine identification number on the Priora?
The engine code is found using these three means:
- lighting device;
- car passport;
- vehicle operating instructions.
The Vin code of a car from the VAZ manufacturer can be located in several standard places, regardless of the modification of the car or the number of valves:
- on the cylinder on both sides or on one;
- near the hole where the amount of engine lubrication is checked;
- where the engine is connected to the automatic or manual transmission;
- at the base of the corrector.
Sometimes the motor coding may be located in a different place. But this rarely happens.
Engine number on 16 valve
The engine number of 16 valves on a Priora can be viewed by first removing the air filter housing. Disconnect the corrugation. Using a mirror, the car owner will see two rows of numbers. Since the coding is located on the cylinder block below the thermostat housing.
To read the numbers and compare with the documentation, you will need to use a rag and WD 40 to clean the metal. The numbers tend to get dirty with dust.
Engine number on 8 mi valve
On an eight-valve Lada Priora engine, the engine coding is in the same place as on a 16-valve engine. The numbers are located on the end of the cylinder block, above the clutch housing. But there are also exceptions.
For example, on new models, the manufacturer may change the location of the motor code. In this case, he usually indicates the location of the VIN code in the technical passport for the car.
Lada Priora is the most stolen car among other domestic vehicles. Therefore, a car owner should always have an idea where the engine coding is located in order to refuse to buy a stolen car. Therefore, next we will talk about exceptions to the location of plates with vehicle data.
Powertrain Maintenance
The frequency of maintenance of the Priora engine by the manufacturer is 15 thousand km. It is recommended to carry out the first maintenance after 3 thousand km. The main attention should be paid to checking all attachment points for attachments. During this same service, the first oil and oil filter change is carried out. If the engine is 8-valve, it is worth checking the valve clearances. For a 16-valve engine, this measure is not necessary, since hydraulic compensators are installed on this power unit. Similar work is carried out after 15 thousand kilometers of the Priora.
After the odometer reaches a value of 30 thousand km, in addition to changing the oil and oil filter, the spark plugs and power system filters require replacement. Often, at this mileage value, the timing tension pulley gradually begins to fail. If the Priora has an 8-valve engine, it will not be superfluous to replace the valve cover gasket.
Design Features
All internal combustion engines on Priora operate at a temperature of 95 degrees. They are able to withstand such high degrees thanks to a special alloy of the cylinder head, which does not deform when heated to high temperatures.
However, if it’s hot outside, the engine quickly heats up and in traffic jams it starts to push and stall. Operating a power device at temperatures above 110 degrees is dangerous for it. The lifespan is reduced, rubbing parts wear out quickly.
Crank mechanism
The engine pistons are made of an alloy of aluminum and silicon. This ensures their high wear resistance and temperature resistance. The head of each piston is cylindrical with a flat bottom. The skirt is oval in cross section and barrel-shaped in longitudinal section.
To improve and speed up the running-in of the mechanism, the entire surface of the piston is coated with tin. And compression rings are cast from cast iron. The outer surface of the upper ring, which is adjacent to the cylinder, is coated with chrome plating. This increases the lifespan of the ring.
The height of the compression rings is 2 mm, and the height of the oil scraper ring is 4.9 mm. The piston pins are made of low alloy steel. They are selected for the pistons with minimal clearance. This is necessary to prevent your fingers from knocking while working.
timing belt
The timing belt of the Priora car is made of a durable belt. Many car owners say that it is the gas distribution mechanism that is the problem with Priora engines. At 100 thousand kilometers you may find cracks on the timing belt or light chips in the rubber. This means that he is living his last kilometers. When replacing a belt, it is best to change the entire gas distribution mechanism. Namely, sprockets, a crankshaft toothed pulley with a washer, sometimes replace the generator belt.
The belts that are installed in engines on Lada Priora have 137 teeth. If one wears out, slippage begins, and sometimes the belt can hit the valves. As a result of the break, it hits the valves with 100% accuracy and bends them.
Therefore, experienced mechanics recommend putting the car in for preventive maintenance every 12 months or 100,000 kilometers. Thus, the car owner will avoid major engine repairs or complete replacement.
Systems
The closed liquid cooling system on the Priora allows the engine to cool better on hot days or when idling in traffic jams. It effectively removes heat and prevents the Priora from overheating even at temperatures of plus fifty Celsius.
The power supply system on the car is injection. Carburetor systems are already a thing of the past. Now the fuel is injected into the combustion chamber at a certain angle, oil and air are supplied and then everything is mixed. Such innovations ensured stable operation of the motor.

The upgraded crankcase ventilation system does not allow large amounts of exhaust gases to be released into the atmosphere. The reduction and modernization of the connecting rod and piston group reduced the amount of gasoline consumed by the Priora engine.
Let's look at the list of cars on which these engines were installed.
Malfunctions
Despite various upgrades, the engine in the VAZ 21127 retained all the faults of its predecessor, the main ones of which are shown in the table:
| FAULT | CAUSE |
| The engine starts to stall | Coking of injectors. |
| Malfunction of ignition coils. | |

Recommendations for improvement
For the first time, it was decided to increase the power of the new Priora 21126 engine at the factory in order to create a sports modification of it. Camshafts with increased lift, a lightweight connecting rod and piston group were installed, and the intake and exhaust tracts were modified. This is how the first domestic sports unit appeared, which was put into production, and they began to install it on the Lada Granta Sport model.
The technical characteristics of the engine are as follows: engine power from the Priora has increased to 118 hp. torque - up to 154 Nm at 4700 rpm, fuel consumption also increased to 7.8 liters per 100 km with a combined driving cycle. We will give a number of recommendations on how to independently increase the power of Priora engines:
- The simplest and most affordable way is to install a zero-resistance exhaust tract. The essence of its work is to reduce the resistance of the path, as a result of which some of the power spent on overcoming this resistance will be released and become useful.
- The same operating principle applies to the zero-resistance intake tract. Installing the receiver and throttle body to 56 mm will allow the power unit to “breathe” more freely, and your Lada Priora will become several horsepower more powerful.
- Deeper tuning - new camshafts with a sports configuration, allowing the intake and exhaust valves to open more. This will give a noticeable increase in the agility of the car, especially in city conditions.
- Replacing the standard valves and connecting rod-piston group with a lightweight one will again release some of the useful energy of the unit and add it to the main power. Here you can kill two birds with one stone: install pistons with recesses, thereby eliminating the possibility of them “meeting” with the valves when the timing belt breaks.
- We should not forget about CHIP tuning. After major changes in the engine configuration, its operating mode will definitely improve, and in order to optimize it and adjust fuel consumption, you need to do a flashing.
Recommendations are given taking into account that the power plant is in good technical condition. If this is not the case, when tuning it is worth replacing worn parts and oil in order to get the desired effect from the changes. As a result of the above measures, the Lada Priora will receive an additional 20-30 hp. without reducing the resource.
How many horses can Priora have in addition to this? Quite a lot, there are capabilities and components to increase the power ultimately to 400 hp. This is due to a radical modification of the power plant: boring the cylinders, grinding the cylinder head, replacing the injectors and fuel pump with more efficient ones, installing four throttle valves and a turbocharger.
We should not forget about modernizing the brake system. Such tuning will give excellent results in terms of power, but the engine life will be significantly reduced, and fuel consumption, on the contrary, will increase significantly.

Chip tuning of the Priora engine
For fun, you can play with the sports firmware, but there will be no obvious improvement; see how to properly increase the power below.
Priora engine tuning for the city
There are legends that the Priora’s engine produces 105, 110 and even 120 hp, and the power was underestimated to reduce taxes, various measurements were even taken in which the car produced similar power... what everyone decides to believe, let’s focus on the indicators declared by the manufacturer. So, how to increase the power of a Priora engine, how to charge it without resorting to anything special, for a small increase you need to let the engine breathe freely. We install a receiver, a 4-2-1 exhaust, a 54-56 mm throttle body, and we get about 120 hp, which is quite good for the city. Boosting the Priora engine will not be complete without sports camshafts, for example, STI-3 camshafts with the configuration described above will provide about 140 hp. and it will be fast, an excellent city motor. The refinement of the Priora engine goes further, sawn cylinder head, Stolnikov 9.15 316 shafts, light valves, 440cc injectors and your car easily produces more than 150-160 hp.
Compressor for Priora
Boring the Priora engine or how to increase the volume
Let's start with how you don't need to increase the volume, an example would be the famous VAZ 21128 engine, don't do that)). One of the easiest options to increase volume is to install a motorcycle kit, for example STI, we choose it for our 197.1 mm block, but do not forget about the jambs of the 128 engine, do not rush to install a long-stroke elbow. You can go the other way and purchase a high block 199.5 mm Priora, 80 mm crankshaft, bore the cylinders to 84 mm and a connecting rod 135.1 mm pin 19 mm, this will give a total of 1.8 volume and without damage to R/S, the engine can be twist freely, install evil shafts and squeeze out more power than a regular 1.6l. To spin your engine even more, you can build up a standard block with a plate, how to do this, how it spins on a 4-throttle intake and wide shafts, and most importantly, how it runs is shown in the video below, watch:
Priora on throttles
Priora turbo engine
There are many methods for building a turbo Prior, let's look at the urban version as it is more suitable for use. Such options are most often built on a TD04L turbine, Niva pistons with grooves, ideally Stolnikov 8.9 shafts, USA 9.12 or similar, 440cc injectors, 128 receiver, 56 damper, exhaust on a 63 mm pipe. All this junk will give more than 250 hp, and how it will go, watch the video
Rules for long-term use
Surely every Priora owner wants to operate his car without unnecessary unexpected costs and is thinking about how to increase the car’s service life. To do this you need to follow a few simple rules:
- The power unit of the VAZ 2170, even without various improvements, has sufficient potential for “spirited” driving. But in order to save it and extend its life, such driving should be avoided. Smooth acceleration and maintaining a stable speed not only on the highway, but also in the city will help extend the life of the engine and save fuel and your own money. The maximum permissible speed on the highway should be no higher than 120 km/h, the optimal speed is 100-110 km/h, and it is important to maintain stability.
- It is important to timely replace consumables, that is, oils in units, filters, spark plugs, high voltage wires, generator and timing belts, and coolant. The interval between engine oil changes depends on its quality and chemical base. Mineral-based oils should be changed more often, synthetic oils less often. You should never determine the quality of motor oil by its color. If it has acquired a black tint, this does not mean that the oil is bad - it means that an excessive amount of combustion product deposits is formed in the engine. First of all, you need to find the source of the carbon deposits and eliminate it, and then change the oil.
- The new engine must be properly broken in, and then the oil must be changed, following the manufacturer's instructions. When running in, avoid increased loads, sudden movements of the accelerator pedal, and do not exceed the speed specified in the instructions.
- Always monitor the engine coolant temperature, check the operation of the electric cooling fan, thermostat and temperature sensor. Overheating is the main enemy of the piston group; every time the temperature is exceeded, it wears out intensely, and the life of the unit is sharply reduced.
“Lada Priora” is a modern high-speed domestic car that will bring its owner a lot of positive impressions and driving pleasure, provided that the engine is cared for and properly modified and operated.
How to extend engine life?
Obviously, a Lada car can be treated very differently. For some, this is a “car” for a couple of years - to get by until the difficult times are over. Someone cares and cherishes their new Vesta. But over time, the attitude towards the car becomes less and less reverent.
Those who want to maximize the life of their cars should:
- Change the oil more often than the regulations require, approximately twice as often.
- Use high-quality consumables and components.
- Do not overload the engine. Both frequent acceleration “to the cutoff” and driving with the pedal “to the floor” at low speeds are harmful.
- Operating the machine with a trailer reduces the service life of the engine.
- Monitor the thermal conditions of the engine. Do not give a heavy load to a cold engine and avoid overheating in summer.
What to do if the number is interrupted
If it turns out that the car owner purchased a stolen car, but the code was broken, then the traffic police will no longer return the documents for the vehicle. In the best case, you will have to buy a new engine, in the worst case, you will have to sell the Lada Priora for spare parts.
It is no longer possible to register or deregister Priora. Riding on it will also be prohibited. That's why it's so important to pay close attention to the VIN code when buying a car.
Conclusion
It’s worth buying a car, but at the same time having a couple of tens of thousands of rubles in your pocket. Familiar car mechanics or a professional on-site inspection will help you save money. Not a bad car if you previously drove a simpler Russian model, such as a Lada, or didn’t have a car at all, just got a driver’s license. In any case, servicing and repairing a Priora is cheaper than a foreign car, so if you want to save money, then this is also your option.

VAZ 21114 – 80 hp
120 Nm This power unit was inherited from the Lada Priora from the previous VAZ 2110 model and was installed only on sedans or hatchbacks in the simplest Standard configuration. Such an engine is rare, since already in 2011 it gave way to the 21116 engine.
VAZ 21116 – 87 hp 140 Nm
There were relatively many design changes in the updated 8-valve unit: a lightweight piston from Federal Mogul, an intake manifold with an electronic throttle, a particularly durable Gates belt with a service life of 200,000 km and an automatic tensioner. The downside is that there are no recesses in the pistons and now the valve bends when the belt breaks.

Engine Features
The Lada Priora engine is simple and reliable, so it rarely needs repairs. A durable cast-iron cylinder block and the coolant passing between them form the basis of the design. The cylinder head is made of aluminum and contains valves. The engine pistons are also made of aluminum. Their bottom is decorated with special grooves that protect the engine from serious damage in the event of a breakdown or accident. The poly-V-ribbed timing belt is securely fastened and protected from slipping. To do this, the belt is limited on one side by a belt, and on the other by a special washer.
The Priora engine of the 126th series was equipped with completely new pistons, which were developed by Federal Mogul. Their weight is 30% less than that of the VAZ-2110. Each piston has three rings, the surfaces of which are protected by tin coating. All these innovations make it possible to extend the life of parts and reduce the cost of their repair. The cast iron crankshaft has an increased piston stroke - in the new model it is 94 mm. The Priora engine valves are made of heat-resistant material and can be rotated during operation, therefore they have less wear.
Lada Priora engines 16 valves
VAZ 21126 – 98 hp
145 Nm In the Norma and Lux trim levels, a 16-valve internal combustion engine was installed, and it was immediately a modernized series with a lightweight piston from Federal Mogul and a durable belt from Gates Rubber Company. Another advantage is hydraulic compensators, which save you from adjusting the valves. This is the most popular Priora unit; it was installed from the very beginning until almost the end of production.
VAZ 21127 – 106 hp 148 Nm
The 2013 update brought a new engine with a variable-length intake manifold. It was with this engine that completely new gearboxes appeared: the manual VAZ 2180 with a cable drive, as well as the VAZ 2182 robot, created on its basis.

Malfunctions and repairs of the Priora 21126 engine
In 2015, production of the NFR sports engine began, called 21126-81, which used the 21126 base. And since 2016, cars with 1.8 liter engines 21179, which also used the 126th block, have been available.
The most basic malfunctions of the 126 engine
Let's move on to the malfunctions and shortcomings, what to do if the Priora engine is running rough, sometimes flushing the injectors solves the problem, it may be the spark plugs or the ignition coil, but the usual thing in this case is to measure the compression in order to eliminate the problem of valve burnout. But the cheapest option is to go to a service center for diagnostics. Another common problem is when the engine speed of the Priora 21126 fluctuates and the engine runs unevenly, a common disease of VAZ sixteen valves, your mass air flow sensor is dead! Not dead? Then clean the throttle valve, there is a possibility that the TPS (throttle position sensor) needs to be replaced, perhaps the IAC (idle air regulator) has arrived. What to do if the car does not warm up to operating temperature, there may be a problem with the thermostat or the frost is too severe, then you will have to put cardboard on the radiator grill
