Replacing the exhaust manifold gasket on a VAZ-2114 with your own hands

Replacing the exhaust manifold gasket on a VAZ-2114 is a very complex procedure and requires certain knowledge and experience. So, not all experienced car enthusiasts are able to do this correctly. In addition to the fact that exhaust gases exit through the exhaust manifold, it is also responsible for the normal operation of the engine, since a lambda probe is installed on it.

The video will tell you how to properly replace the exhaust manifold gasket, and also tell you about some of the subtleties and nuances of this process.

Signs of a burnt gasket

The easiest way is for the owner of a car with an injection engine, the operation of which is monitored by an ECU (electronic control unit). It sends a signal about a gasket failure to the dashboard, where the Check light comes on. This means that the lambda probe, which is usually equipped with the manifold, detected a change in the volume of oxygen in the exhaust, informing the ECU. The engine begins to operate in emergency mode until the defect is eliminated.

“Symptoms” of a burnt gasket:

• the engine is unstable;
• makes an uncharacteristic sound during operation;
• The cabin smells like exhaust gases.

ATTENTION! The fact that the exhaust manifold gasket has burned out is indicated by a recognizable chirping sound created by gases that break through the seal. Motorists often say that the engine “cuts.”

Exhausts through ventilation and heating systems quickly penetrate into the cabin, which is fraught not only with a deterioration of the microclimate, but also with negative consequences for health. This is why replacing the exhaust manifold gasket becomes a forced but necessary measure.

Required tool for replacement

Before you begin the process itself, you need to decide on the necessary tools. So, what will you need: a ratchet and sockets for 17, 19; screwdrivers with flat and Phillips tips; a set of keys and the gasket itself.

Now that everything is prepared, you can start working directly. In order for the manifold to be removed without any problems and rusted bolts not to create trouble, everything must be lubricated with WD-40 before performing the operation. It is advisable to do this several times. Before performing the operation, you need to think again, weigh everything and calculate your strength.

We are replacing the gasket

As you can see, the replacement of the intake and exhaust manifold gaskets takes place simultaneously and, by and large, is the same gasket material.

Part selection

21083-1008081 – original catalog number of the gasket for the intake and exhaust manifold. It consists of two parts or, on newer models, one. This part is produced at the AvtoVAZ plant. The average cost is 250 rubles per piece (if there are two of them) or 450 rubles (for a whole one).

In addition to the fact that there is an original part, you can also find a number of analogues that are recommended for installation. Let's consider which gaskets can be installed under the VAZ-2114 manifolds:

• Trialli GZ 102 0013 is a well-known Russian manufacturer that produces a wide range of analog parts for domestically produced cars. The cost of the gasket is 200 rubles per piece.
• AJUSA 13065200 is another domestic manufacturer that has won consumers over the quality of its products. The cost of the product is 450 rubles.
• Ukrainian also produces and supplies this gasket. But, if you look at it, the quality of the product leaves much to be desired, since the resource is designed for only 20,000 km.

Replacing the gasket

The marker of a failed gasket is considered to be soot that forms in the place where the exhaust escapes. In this case, proceed to replacing the defective seal.

What is needed for repair

To replace the exhaust manifold gasket, prepare the following materials and tools:

• screwdrivers (slotted and Phillips);
• sharp knife or spatula (remove used gasket);
• spanners included;
• anti-rust liquid (for example, WD-40);
• 5 liter wide-neck container (for draining antifreeze);
• dry rags.

ATTENTION! When replacing the manifold gasket on a VAZ 2114 (as on other factory models), it is necessary to drain the antifreeze in advance, otherwise the engine intake windows can be flooded.

Step by Step Actions

The process of replacing a seal when it fails is simple, but has nuances for different engines. In general terms, the algorithm for dismantling and subsequent installation of the VK gasket looks like this:

1. Open the hood and remove the air intake with the carburetor, under which there is a manifold.
2. Remove the thermal screen covering the VC (some older models do not have a screen).
3. Unscrew the bolts that attach the spider to the exhaust pipe, and then the bolts connecting it to the engine block.
4. Proceed to removing the exhaust manifold itself, on which sits a burnt-out gasket, which often “sticks” to the VC.
5. Carefully clean the area between the cylinder head and the manifold with a spatula, removing carbon deposits and fragments of worn gasket from the second.
6. Once the area is shiny, coat it with graphite lubricant and install a new gasket.
7. Treat the fasteners with the same lubricant (to prevent corrosion).

Finally, return all dismantled parts to their rightful places.

Replacing the gasket VAZ 2114

First, remove the engine protection from the car standing on the overpass, having previously drained the antifreeze, and then proceed as follows:

1. Remove the air filter, having first disconnected the negative terminal of the battery.
2. The fuel pipes with the accelerator cable are disconnected from the throttle.
3. Disable the idle speed/throttle sensors.
4. Disconnect the crankcase ventilation and brake booster hoses, turning off the receiver.
5. Remove the latter by disconnecting the wires at the injection control unit.
6. Dismantle the fuel rail without unscrewing the injectors.
7. The receiving pipe is detached from the VC.
8. Remove the intake and exhaust manifolds one by one.
9. Remove the old gasket.
10. Clean the joint between the manifold and the cylinder head with a knife.
11. Install a new gasket and perform reverse installation.
12. Fill in coolant.

The exhaust manifold gasket will last a long time if you use quality fuel and monitor antifreeze levels to prevent engine overheating. You also check the reliability of the joint between the cylinder head and the cylinder head and immediately change the gasket if you notice its malfunction. In addition, you need to buy gaskets from reputable manufacturers.

Replacing the intake manifold gasket of a VAZ 2114

It is recommended to replace the gaskets on the VAZ intake manifold after each removal. But I had to do this prematurely, as I discovered a significant air leak, which mainly manifested itself on a cold engine. Every cold start was accompanied by a terrible tripping.

In addition to the tripping when cold, there was a slight drop in speed when sharply pressing the gas pedal. This applies to both a cold and a hot engine.

A homemade smoke generator made from a cigarette helped me detect the air leak. A very simple and primitive contraption that has helped me out more than once.

My car (Kalina 1.6 8 valves) has a plastic intake manifold (receiver). The same will be installed on all VAZ family cars with an 8-valve 1.6-liter engine (2114, 2110, etc.). 4 rubber rings act as gaskets. According to reviews, black rings last much longer than white ones. And I was convinced of this personally - these gaskets lasted for about six months and began to let air through. They felt like plastic to the touch. Unfortunately, I didn’t find black ones, so I’ll install white ones again. I hope these last longer.

To remove the intake manifold (receiver), you must first unscrew the corrugation from the air filter, the throttle cable, and the small crankcase ventilation hoses. I will not remove the throttle and its heating.

The intake manifold is attached to 5 studs - one in the center, two on the sides. To unscrew them you will need a 13mm socket. After unscrewing the nuts, you need to remove the receiver itself from the studs and move it to the side. Remove the old gaskets and wipe the seats from oil and dirt. You also need to wipe the seat on the engine.

The manifold has special grooves for guides on the gaskets. The gaskets must be installed with the higher side in the plastic manifold. It is the guide that will prevent you from making mistakes.

I additionally coated the areas near the guides with sealant on the outside of the gasket. Because it felt like that was where the ring entered the groove the deepest. In addition, there was a place for air leaks on the old gaskets.

After all procedures, the intake manifold can be installed back. I couldn't find any information on how tightly to tighten the mounting nuts. I delayed it at my own peril and risk. The main thing is not to overtighten, as the manifold is plastic and can crack.

This is how I replaced the old intake manifold gaskets on my Kalina with new ones. There is no more air leakage, the engine stopped stalling when cold and began to behave much better when warm.

The main signs and causes of failure of the VAZ 2114 intake manifold

• The main symptom of a failed intake manifold is a sudden loss of car engine power.
• at the same time, there is an increase in fuel consumption , with a deterioration in traction and a drop in engine performance.

1. Often a problem is indicated by a missing stud in one of the manifold flanges. It simply comes off when the collector goes “screw”, that is, due to temperature changes, for example in winter, or over time (average service life is 7 years), the collector begins to bend along the plane, and the pin simply “spits out”, pulls out .
2. Due to the fact that the manifold has “leaded”, a crack may form and, as a result, exhaust gases from the engine escape, and the manifold must be replaced.

Tips for replacing the intake manifold

Also, do not neglect the procedures for repairing and cleaning the intake manifold. The stability of the VK is very important for the normal functioning of the car. A certain vacuum is formed in the intake manifold, which is the source of drive force for many systems: cruise control, windshield wipers, vacuum brake booster. In the event of a collector malfunction, this threatens the failure of one or more of the above systems.

To avoid the appearance of cracks and distortions, you must use a torque wrench to tighten the nuts on the manifold and follow the tightening order of 20.9-25.8 (2.13-2.63) N_m (kgf_m). As a rule, it is recommended to start tightening the nuts from the center and gradually move towards the periphery, alternately tightening the nut on one side or the other.

To work on removing and replacing the VAZ 2114 intake manifold on an 8-valve engine, we will need:

• keys “for 8”, “for 10”, “for 13”, “for 17”;
• “cardan” type nozzle and socket heads “17”, “19”;
• magnetic screwdriver;
• screwdrivers, pliers;
• new intake manifold.

By the way, the price for an intake manifold from a VAZ (article 21110100801420) will be 1,350 rubles.

The cost is indicated for spring 2022 in Moscow and the region.

Loosen the clamp and disconnect the crankcase ventilation hose.

Causes of malfunctions

The key factor that causes 90% of exhaust manifold malfunctions on VAZ 2114 cars is high temperature and even poor quality materials where the parts are made. During operation, the steel heats up and cools down repeatedly, which leads to the appearance of cracks in the body. This is a common occurrence for VAZ cars older than 7-8 years.

Auto repair shops offer crack welding services using argon welding. However, for a number of reasons, this activity is useless for cars older than 7 years.

See:

1) Just removing and installing the exhaust manifold will cost about 3.5.5 thousand rubles. Taking into account the work of the welder and other actions, the cost of repairs can be 4-5 thousand rubles. If you do the work yourself, buying a new part will cost less.

2.7) Welding, even argon welding, disrupts the structure of “tired” metal. A boiled part rarely lasts longer than a year, then new holes appear. The older the car, the faster the problem returns, and the collector has to be removed again.

If the car is older than 8 years and there are problems with cracks in the manifold, it is better to remove the part and replace it with a new one.

Signs of trouble

Pad

exhaust manifold

One of the main signs of a leak in the system is a “sporty” growling sound when the engine speed increases. You will like this as a symptom of various exhaust malfunctions that allows you to conduct accounting (software). To check, it is better to take an assistant and go to the garage with a pit, as it is also called, to the overpass. More often it is determined by eye whether the problem lies in the muffler, resonator or exhaust.

Gasket wear may become apparent during planting. Open the hood and start the car - white, or grayish smoke, rising from unfamiliar manifolds during warm-up, indicates a leak. VAZ car owners usually encounter this problem once every 3-4 years. With the use of low-quality spare parts and 30 years. The solution may be to manufacture a custom-made steel gasket. It will last as long as the entire collector.

Service specialists, when attracting clients, like to tell horror stories about the explosion of the exhaust manifold on VAZ 2114 cars due to cracks. In fact, this is more than a myth. However, the real problems of two or more are serious, so repairs should not be put off.

Replacement of cylinder head gasket for VAZ 2114 8 valves.

Cracks in the exhaust manifold or a worn gasket usually cause the engine to run dirty.

1) A lambda probe is installed in the exhaust manifold, which affects the operation of the accounting (software) injection. Strong air suction disrupts the oxygen mass content in the exhaust; the lambda incorrectly adjusts the quality of the mixture, causing tripping, uneven idling, loss of power, and “black” spark plugs.

5) Additional function – crankcase ventilation. Impaired air circulation causes disturbances in the operation of the gas distribution mechanism, increased wear of the valves, the formation of carbon deposits on the pistons and other “joys”.

If increased noise and unpleasant odors during engine operation are combined with dirty work, the car requires repair.

How to replace the cylinder head gasket of a VAZ-2114 8 valve

The cylinder head (cylinder head) gasket is a disposable part and therefore cannot be repaired. If for some reason it is damaged, it is necessary to replace the cylinder head gasket in a VAZ-2114 8-valve car. You can understand that this part needs to be replaced by the following signs:

1. Coolant is constantly bubbling in the radiator.
2. Exhaust gases escape through the gasket.
3. The exhaust pipe smokes.
4. The oil on the dipstick is covered with a white emulsion that looks like foam.
5. The coolant is oily.

Often a sign of such a problem is thick white smoke from the exhaust pipe. This occurrence indicates that the gasket has developed a blowout between one cylinder and the coolant leak hole. If the liquid is oily, this indicates the presence of a breakdown, as a result of which oil began to enter the channel with the coolant. If a sharp whistle is heard when the engine is running, and traces of oil are visible on the cylinder block, this indicates a gasket breakdown.

Also, a sign of gasket failure may be an increase in fuel consumption and a decrease in engine power. However, it is worth considering that some of these signs also occur with other damage to the car’s mechanism. For example, a white emulsion on the surface of the oil also indicates that the block has a crack. In any case, you must first make sure that the cause is a faulty cylinder head gasket.

If in doubt, it is better to entrust the diagnosis to a specialist.

Tools and necessary parts

To remove the exhaust manifold on a VAZ 2114 with the intention of replacing the gasket or the entire part, you will need the following tool:

• open-end and ring wrenches for 8, 10, 13, 17;
• wrench with heads 17, 19;
• screwdrivers, pliers.

It is also advisable to have tools such as a Dremel, a nutcutter, or a nutcutter. You, the fasteners on the parts of the exhaust accounting system are stuck tightly.

A few days before your planned repair, begin treating accessible nuts with WD-40 or another penetrating lubricant. Repeat the operation 2-3 times. This will make the task of removing the manifold a little easier .

The question often arises: is it worth using a sealant after removing and replacing the gasket? Experts believe that if you apply sealant to the gasket, it should only be high-quality silicone. A bad sealant can bring a lot of trouble to a VAZ 2114 engine: when it burns out, it turns into “pellets” that are pulled into the crankcase. As is known, unnecessary contamination of the piston allows accounting (software).

Preliminary work

Replacing the VAZ 2109 intake manifold gasket with your own hands is not very difficult and does not require specific knowledge or expensive tools - the required set of keys is usually present in the trunk of every car enthusiast.

But before replacing, you should try to tighten the fastening of the intake unit - if the gasket is not burned out, it is the loose fastening that may cause exhaust gases to get under the hood. If tightening the fastening does not help, it means that the gasket is completely burned out and needs to be replaced. Replacing the VAZ 2109 manifold gasket will require preliminary work to dismantle the air filter, remove the carburetor and the manifold itself. All of the above work is carried out exclusively on a cold engine.

Removing the air filter with housing

On the injection engine of a VAZ 2109 car, to remove the air filter, it is enough to unscrew the four self-tapping screws securing the cover of the filter element housing - for this, use a 10mm wrench or a ratchet. There will be a filter element under the cover. If the cover is difficult to lift, you can disconnect the mass air flow sensor from the plug.

On a carbureted engine, there are three latches under the hood that can be easily opened. There is a screw in the middle of the metal cover, which can also be unscrewed by hand, after which the cover is removed. Under the cover there is a filter element that must be carefully removed. Subsequently, during reassembly, the filter element can be replaced - if the time has come or if the filter element is very dirty.

Removing the carburetor

After the air filter has been removed, you can begin to remove the carburetor. To remove the carburetor on a VAZ 2109, you will need the following tools:

• two screwdrivers - flat and Phillips;
• 13 open-end wrench;
• head at 8;
• ratchet.

Instructions for dismantling the carburetor will be as follows:

1. The coolant supply hose to the carburetor starter is disconnected from the fitting by unscrewing the fastening clamps. The coolant itself is drained into a previously prepared container.
2. The exhaust pipe coming from the exhaust manifold and from the cylinder block bracket is disconnected.
3. Then the throttle cable bracket is disconnected. To do this, first remove one end of the spring from the throttle control rod, and then remove the entire spring, then loosen the nut on the bracket and remove the cable from its engagement.
4. The EPHH screw sensor is disconnected from the power plug.
5. Two hoses and a vacuum tube are disconnected from the carburetor heating unit.
6. The crankcase ventilation hose is removed.
7. Unscrew the 4 nuts securing the carburetor to the intake manifold.
8. The carburetor is removed carefully and without jerking - by lifting it from the studs.

The work of removing the carburetor is completed. The presented photos and videos will help you clearly follow the process of removing the carburetor.

Removing the intake manifold

After the work of removing the air filter and dismantling the carburetor is completed, you can begin to remove the intake unit. To do this you will need the following set of tools:

• open-end wrench 13;
• head 13 - regular and deep;
• ratchet and crank;
• ratchet with 10mm head.

The work order will be as follows:

1. The platform located under the carburetor is bent back - to do this, two fastening nuts are unscrewed.
2. All hoses leading to the manifold are disconnected.
3. Six mounting nuts are unscrewed from the intake manifold.
4. The intake manifold is removed from the studs - to do this, it should be slightly rocked from side to side, as it can burn to the gasket.

Removing the exhaust manifold

Removing the VAZ 2109 exhaust manifold will require the following tools:

• wrenches 13 - open-end and cap;
• deep head at 13;
• ratchet.

Work order:

1. The four nuts securing the exhaust pipe are unscrewed from the manifold.
2. The “pants” are pulled off the studs and moved to the side, then the remaining three nuts securing the manifold are unscrewed.
3. The exhaust manifold is carefully and without jerking removed from the studs.

When removing the collectors, a problem may arise such as sticking of the studs and nuts - since the metal is constantly heating and cooling, a souring process occurs.

To make work easier, the fastening studs can be filled with WD 40 liquid in advance, about a day before starting work. This will make it much easier to remove the manifold for subsequent gasket replacement. \

If the pin breaks off when unscrewing, you just have to drill it out, and then cut a new thread and screw on a new pin.
