Pros and cons of the motor
The main feature of the ICE 21127 remains the insufficient safety of the valves, which can be bent by the pistons if the timing belt breaks. The second disadvantage is the expensive overhaul, even if you do it yourself:
- the timing belt complete with automatic tensioner and pulley is expensive, as it is produced by the foreign company Gates;
- The ShPG kit also has a high price, since it is manufactured by another foreign manufacturer, Federal Mogul.
The advantages of the design are:
- attachments are conveniently located, which reduces labor costs for maintenance and repairs;
- increased torque and power of the internal combustion engine.
On the one hand, the manufacturer AvtoVAZ has expanded its line of engines with version 21127. On the other hand, it has provided a new spare part - an improved receiver with an inertial charging system, which is a definite plus:
- owners of Grant, Prior and Kalin of the second generation, equipped with 21126 engines, can buy this unit;
- install it yourself instead of the standard receiver of the previous configuration;
- remove the mass air flow sensor, install DBP and DTV sensors to get a power of 106 hp. With. instead of the factory 98 hp. With.
There are no other changes in the design of the internal combustion engine; there is no need to re-register the car with the traffic police. Transport tax and insurance will be cheaper, since the plant’s vehicle certificate indicates less power.
Design features of the Lada 21127 16 valve engine
The donor for the new power unit was the already well-known VAZ 21126 engine. The main difference from its predecessor is the use of a modern intake system with flaps. Let us briefly describe the principle of its operation. Air enters the cylinders in different ways: at high speeds it is directed along a long path, and at low speeds it is directed through a resonance chamber. Thus, the completeness of fuel combustion increases: i.e. power increases - consumption decreases.
Another difference is the abandonment of the mass air flow sensor in favor of DBP+DTV. Installing a combination of absolute pressure and air temperature sensors instead of the mass air flow sensor saved owners from the common problem of floating idle speed.
Otherwise, this is a typical VAZ injection 16-valve unit, which is based on a cast iron cylinder block. As on most modern Togliatti models, there is a lightweight Federal Mogul ShPG, and the Gates timing belt is equipped with an automatic tensioner.
Typical breakdowns, causes, elimination
Since the 21127 motor uses a lightweight ShPG, as a result of a sudden belt break, the piston is 100% guaranteed to bend the valve. In addition, there are “diseases” characteristic of this motor:
| Power reduction | 1) burnt valves 2) clogged air filter 3)fuel system malfunction 5) wear of camshaft cams | 1)replacement of valves 2) cleaning or replacing consumables 5) installation of a new camshaft |
| The internal combustion engine runs after the ignition is turned off | 1) carbon deposits inside the combustion chambers and on the valves 2) Problems with the ignition switch | 1)washing with a cleaning agent 2)replacing the ignition switch |
| Emergency pressure lamp comes on | 1) wear of the oil pump or main bearings 3) low oil level | 1) replacing parts 3) adding lubricant to the level |
In principle, no special complaints were noticed with the ICE 21127; this power drive is considered reliable and economical to operate.

Which cars are equipped with ICE 21127?
Immediately after development, engine 21127 is recommended to be installed on cars manufactured by AvtoVAZ:
- Lada Granta - since 2013, Lux and Norma configurations;
- Lada Kalina-2 - since 2013, only with a manual transmission, mainly on sedans and hatchbacks;
- Lada Priora - since 2013, Luxury equipment.
Lada Priora Luxe configuration
In principle, the engine’s sufficiently high performance characteristics made it possible to install it on the Lada Largus, Vesta and X-Ray. However, by the time of their serial production, the ICE 21127 had been upgraded to the next version 21129 with a control unit that complies with Euro-5 standards, so the plant management limited itself to the indicated modifications, leaving the volumes the same.

Oil

Oil sump volume
This point will be useful for those who are going to change the engine oil. With different transmissions, the volume of oil poured into the engine is also different.
VAZ 21129 + Renault manual transmission (cast crankcase) = 4.4l
VAZ 21129 + robot (stamped crater) = 3.2 l
The engine resource is 200 km. But in practice, you need to monitor the condition of the roller, pump and timing belt, because if individual valve elements jam, they will meet the piston group, and then both will come to an end. In addition, during the impact of these elements, it is not uncommon that the crankshaft bends slightly. You can drive with such a crankshaft, but there will be huge oil consumption.
Reliability, weaknesses, maintainability
Reliability
According to the majority of car owners, the VAZ-21127 engine is reliable and, what is especially pleasing, economical to operate. The reliability of the motor is confirmed by many factors.
Firstly, a resource. The manufacturer stated 200 thousand km. But practice shows that in reality it easily reaches 300-350 thousand km and this is not the limit.
The only thing you need to know is that such a mileage is only possible with proper care of the engine. This concept includes timely maintenance, the use of high-quality fuels and lubricants, reducing the time required for regular maintenance, and careful operation of the internal combustion engine.
Secondly, a high safety margin. Despite the fact that during assembly the VAZ-21127 already received factory tuning, the possibility of increasing power remained. But you need to be extremely careful in this matter - additional tuning of the engine significantly reduces its service life.
The pursuit of “extra horsepower” will result in a major overhaul of the entire engine in the near future.
Thirdly, engine reliability is ensured by the presence of imported parts and components (fuel rail, timing belt, tensioner, idler pulley, connecting rod and piston group, etc.).

Fourthly, the reliability of the internal combustion engine has been increased by improving some components and parts in comparison with its predecessor. Thus, the exhaust tract, the ignition system, the use of a metal impeller in the water pump, the replacement of the mass air flow sensor and a number of other innovations have been changed.
Thus, the sufficient reliability of the VAZ-21127 is not a myth, but a reality.
Weak spots
Despite the improvements made to the base model, the VAZ-21127 is not without weaknesses. Among them there are those that appear due to the fault of car owners.
Engine tripping. Most often, this problem occurs due to clogged fuel injectors or faulty spark plugs. In the first case, it is enough to flush the fuel system; in the second, you will have to change the spark plugs.
When the engine fails, the main share of the blame lies with the car owner, since untimely maintenance and refueling with low-quality gasoline are what cause this malfunction. Timely replacement of spark plugs (after 15-20 thousand kilometers of a car) also eliminates this problem in the internal combustion engine.
The next weak point is the possibility of engine overheating. The author of this phenomenon is a faulty thermostat. Its timely replacement prevents overheating of the motor. In this case, all elements of the cooling system must be clean and in working condition, the coolant level is normal, and there are no leaks in the system.
Electrical malfunctions. Here, first of all, doubts about the performance are caused by the ECU, ignition coils and sensors. The true cause of failures can only be identified by diagnosing the engine at a specialized service station.
Timing belt Engines manufactured before July 2022 are of particular concern. Their problem was that the valves were bent when the timing belt broke. The manufacturer stated its resource is 180-200 thousand km, but you should not delude yourself with this.
The fact is that the belt can wear out, but the deflection pulley does not. At about 80 thousand km, the car jams. As a result, the drive belt breaks.
The condition of the timing belt must be monitored
Engines manufactured after this date do not have the problem of bent valves. This is facilitated by specially designed pistons.
Car owners often notice extraneous knocking noises in the engine. As a rule, this noise is created by hydraulic compensators. But knocking can also be caused by an extremely worn SHPG, or, less commonly, by burnt-out valves. In any case, when knocking occurs, the engine requires professional diagnostics.
Malfunctions detected and corrected in a timely manner postpone repairs for a long time.
Features of 21129 engine/differences
The main feature of the 129 engine is the “innovative” for AvtoVAZ installation of an intake receiver with variable chamber geometry and volume. Due to the damper, the volume of the intake chamber changes depending on the speed. As practice shows, the damper is activated at 3500 engine speeds.
In addition, the engineers managed to get rid of the mass air flow sensor - mass air flow sensor. Along with him, his ailments went away, which tormented the owner of the 21126 engine: unstable idling, sometimes exorbitant consumption, high cost. Instead of mass air flow sensors, engineers installed a connection from DBP and DTV sensors (atmospheric pressure and air temperature sensors). This is where the differences from the 126 engine end. Speaking in fact, the intake system with variable geometry is as old as the world and has been installed by global manufacturers almost since the 80s.

Maintenance
In order to carry out major overhauls as rarely as possible, it is recommended to service engine 21127 according to the regulations:
- The timing belt drives the timing pulleys for 20–50 thousand km, but it needs to be inspected three times more often;
- The oxygen sensor has a slightly shorter service life - 10 thousand hours;
- The cooling system and the antifreeze itself, filters and fuel tank cap can withstand 40 thousand km of operation;
- the threshold of 25 thousand mileage cannot be overcome by spark plugs, belts and attachment belts;
- The filter along with the oil is changed every 10 thousand km.
To save budget, the internal combustion engine device allows you to perform all the specified maintenance operations in the garage without visiting service stations.
Engine tuning 21129
Tuning the 21129 engine is no different from the 126 engine.
Easy tuning : Euro-2 or Euro-2 firmware + installation of 4-2-1 exhaust
Medium tuning : Exhaust 4-2-1 + Shafts + firmware (preferably flashed online)
Deep : includes modification of the head, replacement of valves, pushers, etc. All technical characteristics of Vesta.
Guys, with which engine is it better to take 126 or 127 (106 hp)? About the Priora 1.8 with an engine of 128 (124 hp) the reviews are bad, that they bring it to the service in tow, the timing roller gets stuck.. In general, let's discuss which engine with is it better to take?)
