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.

Exhaust manifold functions
It consists of several pipes that merge into one, but has different mountings and configurations for different engines. To produce VC, high-carbon cast iron, stainless steel and titanium are used, sometimes coated with ceramic/chrome.
The task of the “spider” (as the exhaust manifold is called in the Russian Federation) is to transfer combustion products collected from all cylinders to the exhaust pipe. Gases from the AC enter the catalyst or directly into the exhaust pipe and then to the muffler. The exhaust manifold is attached to the engine, or more precisely to the cylinder head (cylinder head), sealing the joint using a special element.
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 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.

What does a faulty collector affect?
There are many stories about the rupture (and even explosion) of a cracked manifold while the car is moving.
Of course, none of them are true, but nevertheless, a leaky manifold is a very serious problem that requires an immediate solution, and here’s why: through burnouts and cracks, air can enter the exhaust system, diluting the exhaust gases.
As a result of this, the lambda sensor will incorrectly determine their composition and incorrectly adjust the composition of the fuel-air mixture injected into the engine, which will lead to tripping, a drop in speed and carbon deposits on the spark plugs.
Bent valves due to incorrect valve timing
These same cracks will affect the crankcase ventilation, disrupting it. This will lead to timing problems and increased valve wear. And finally, exhaust gases escaping through the burnouts will enter the engine compartment and, partially, into the interior, causing unpleasant odors and discomfort during trips.
A severely burnt manifold gasket can lead to exactly the same consequences as cracks on the part itself.
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.
- 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 .
- 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.

Manifold dismantling procedure - step-by-step instructions
The dismantling process itself is not so complicated; access to some nuts is difficult, so it is advisable to carry out the work on a lift or in an inspection pit. The algorithm of actions for the injection VAZ-2114 in this case looks like this:
- Remove the negative terminal from the battery or turn off the mains switch.
Remove the terminal from the battery - Drain the antifreeze from the system.
This point should not be neglected, despite the fact that the factory does not oblige you to empty the cooling system of liquid. Drain the coolant from the system - Disconnect the fuel pipes.
Removing the fuel pipes - We find the throttle position sensor, idle speed sensor and remove the wires from them.
Disabling the throttle position sensor - We remove the crankcase ventilation hoses and the hose from the vacuum brake booster.
Unscrew the pipes - We dismantle the receiver, disconnect the injector wires and remove the fuel rail assembly. We dismantle the receiver. We disconnect the electrical connector of the fuel rail. We dismantle the fuel rail.
- We get full access to the collector.
We dismantle the thermally reflective screen. Removing the thermal shield - Unscrew the muffler exhaust pipe from the manifold.
Disconnect the muffler exhaust pipe from the manifold - Unscrew the manifold mounting nuts from the studs in the block head.
Dismantling the exhaust manifold mountings - We dismantle the collector.

Replacement of gaskets and installation of manifold
After dismantling the manifold, it is rarely possible to remove the gasket intact. It changes in any case , but parts of the destroyed gasket will definitely remain on the mating plane on the head side and on the manifold side. They must be carefully removed.
Changing the manifold gasket
To do this, you can use a special spray that softens the gasket residues; you can carefully remove them with a blade. In this case, the plane must not be damaged, otherwise the tightness of the connection will be broken.
Also, when installing new exhaust manifold gaskets, it is not recommended to use sealants . They can be of different quality, and during crimping they can form particles that get into the crankcase, which is extremely undesirable.

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.

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.

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.
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).

Preparation stages
To replace the manifold or its gasket, in any case you will have to dismantle the VK. But before you get to the element you are looking for, you will first need to go through some preparatory steps. Namely, tighten the fasteners, and then remove the air filter and carburetor if the first stage does not help.

All dismantling work must be carried out only on a cold engine. To make it easy to unscrew all fasteners, you can pre-treat them with WD40, several hours or even a day before the repair begins.
