VAZ cars of the 2112 family were produced with one of four engines. Two of them are 8-valve, two more are 16-valve. The 8-valve motors have grooved pistons so the valves cannot bend. But this property does not apply to any Lada cars: almost all 8-valve valves during the transition. It is known on which of the engines VAZ-2112 never bends the valve - it remains the motor 21124 (1.6 16v).

See how difficult it is to change valves on a Ten. All steps in one video

We are talking about 2111 and 21114 engines. They are injection engines, and the shape of the pistons was inherited by them from the 2110 carburetor engine.

ShPG elements (pistons) 2110-1004015

Actually, the same pistons were installed on three different 8-valve valves: 2110, 2111 (1.5 8v), 21114 (1.6 8v). The piston article number is 2110-1004015.

Two deep grooves ensure that any of the valves, intake or exhaust, can not "meet" the surface of the piston, even if the timing belt breaks.

The standard 8-valve valves on the VAZ-2112 do not bend the valve, no matter what some owners say. Sometimes, and if the valves fly out more than provided by the VAZ, then there will be no guarantee against bending. Therefore, follow the regulations.

And the following is provided:

• Intake valve lift - 9.4 mm;
• The lift of the exhaust valve is 8.95 mm.

We quote the values ​​taking into account the thermal gap. Whoever exceeds them will get the result.

Are 16-valve engines bent?

ShPG elements (pistons) 2112-1004015 and 21124-100401504

In pistons 2112-1004015, the grooves are indeed made. The probability of kinking is reduced, but it is not reduced to zero. Therefore, always pay attention to the rollers and rollers on a 16-valve engine.

The VAZ-21124 engine is one of those 16-valve engines that do not bend their valves. The grooves are made so that no valve meets the piston.

Items:

• 2112-1004015 - the piston of the VAZ-21120 engine (1.5 16v);
• 21124-100401504 - the piston of the internal combustion engine VAZ-21124 (1.6 16v).

Make no mistake when choosing.

Motors 21124 are in short supply!

One of the most beloved engines on a 12-ke is 124. It does not bend the valve, it rides well, but what else is needed?

The number of VAZ-21124 engines produced for the entire time is difficult to calculate. Maybe it even exceeds the number of 20 motors. The 21124 engine had a Euro-4 version, and this engine, regardless of the version, is in short supply. Prices also remain high. Well, a less voluminous 16-valve valve is rated lower, despite the fact that it is more powerful!

Used motors that bend their valves are no longer needed by anyone. It cannot jam, the belt will break and the owner "got" on the capital. Draw conclusions.

On what motor VAZ valve bends

Many motorists are interested in this question, on which cars, or rather engines, valve bends at broken belt Timing? It is not difficult to figure out these engine modifications.

Let's start in order. When the first VAZ 2110 cars appeared, 8-valve engines were installed on them, with a volume of 1.5 and later with a volume of 1.6 liters. On such engines, in the event of a belt break, the valve did not bend, because the pistons did not meet the valves.

A little later, in the tenth VAZ family, a VAZ 2112 car appeared with a 16-valve engine, with a volume of 1.5 liters. Here the first obstacles for the first owners of these cars began. The design of the motor has changed quite a lot, thanks to the 16-valve head, and the power of this motor has increased from 76 horsepower to 92 hp. But in addition to the advantages of such a motor, there were also shortcomings. Specifically, for broken belt Timing on such engines, the pistons met with the valves, as a result of which the valve bent. And after all this, the owners of cars with such engines expected expensive repairs, which would cost more than 10,000 rubles.

The reason for such a breakdown, like bent valves, is in the design of a 1.5 16-valve motor: in such motors, the pistons do not have recesses for the valves, as a result of which, when the belt breaks, the pistons beat on the valves and the valves are bent.

A little later, new 16-valve engines with a volume of 1.6 liters began to be installed on the same VAZ 2112 cars. The design of such engines was not much different from the previous ones with a volume of 1.5 liters, but there is one fundamental difference. In a new engine, the pistons are already installed with grooves, so if the timing belt breaks, the pistons will no longer meet the valves, which means that expensive repairs can be avoided.

A couple of years have passed, and Russian car owners are already accustomed to the fact that 16-valve engines have become reliable, so to speak, injury-safe in relation to the valves. But a new car came off the assembly line, one might say a refreshed 10-ka Lada Priora. All owners thought that since the Priors are equipped with a 16-valve engine volume of 1.6 liters, then the valve bend will not be. But as practice has shown, in cases of a break in the timing belt on the Lada Priora, the valves meet with the pistons and bend them. And repair for such engines will be even more expensive than the twelfth engines. Undoubtedly, the possibility that the belt will break on the Priora is not the highest, because the timing belt is actually twice as wide as on the twelfth engines. But, if you come across a defective belt, then the possibility of a belt breaking increases significantly and it is simply unrealistic to find out when a break will occur.

Also, on new engines that are installed on: 1.4 16-valves, there is also the same problem, when the belt breaks, expensive repairs cannot be avoided. So, it is necessary to monitor the condition of the timing belt at all times. Muting the EGR valve (EGR) on the Nexia Muting the EGR (exhaust gas recirculation) valve on the A15MF engine (16-valve Nexia N-100). The EGR valve (EGR) is used to reduce the toxicity of exhaust on 16-valve Nexia engines by diluting the freshest air-fuel consistency with exhaust gases taken from the exhaust ...

Before buying a car, many owners do not yet know about such a problem as a broken timing belt, and as a result, pistons collide with valves on some engines and bend them. This problem exists not only in domestic cars, but also in modern foreign cars, and this threatens with rather expensive repairs. This trouble was still with the old models of Zhiguli, but now we are interested in modern engines and it is them that we will consider. And on the left in the picture, the consequences of this trouble are shown, so carefully read the information below to avoid a similar picture, because as they say, no one is immune from this.

Bends valves on the following motors

1. 16-valve engine with a volume of 1.5 liters. Although it is no longer installed on cars, at one time there were quite a few of them on the tenth family. Then the owners of these cars felt what it was. On a personal example, 2112, my valve bent 2 times. And in both cases, after replacing the timing belt, not even 10,000 km have passed.
2. Model 21126, which is currently installed on both Kalina and Priors and Grants. As you already know, the collision of valves and pistons is also inevitable when the belt breaks. Moreover, repairs can be very expensive, since, in addition to all this, it can break the entire piston, from the pistons themselves to scoring on the cylinders and bent connecting rods.
3. Modification 21116, which is now being put on both Grants and Kalina recently. Although this sia unit is 8-valve and has not changed much, it will bring a lot of trouble when the pistons and valves meet. This is due to the fact that the piston group in this engine is lightweight, so there is no space for the recesses in the pistons - accordingly, the valves are bent.
4. 1.4 16-cl. For the first time, the engine was installed on Kalina and it is also unsafe, although quite economical.
5. VAZ 21127, which will be installed on the Lada Kalina for the first time. It has a volume of 1.6 liters with a similar design to its predecessor from the Priora, but slightly more power. He also belongs to this list of "dangerous" motors.

The valve does not bend on motors such as:

• 1.5 8-cl and 1.6 8-cl. The power unit with a smaller volume was installed on earlier versions of cars. And 1.6 for late ones, including Kalina too. Everything is fine here and no breaks in the timing belt are terrible, since the pistons have deep recesses for the valves, which are quite enough to avoid a collision.
• 1.6 16-valve modification 21124. This engine was installed on the VAZ 2112 at one time and was in rather popular demand, as it was both powerful and reliable in this regard.

In order to somehow reduce the likelihood of getting into expensive repairs, be careful with the choice of components and spare parts. Change the belt in time and before buying it, carefully inspect it for the presence of a seam, and if there is one, then it is better to abandon it. And don't forget about videos, which must also be of high quality.

Malfunctions and repair of the VAZ 11183/21114 engine

Engine 21114, the second name 11183 is a further development of the 2111 1.5 liters. and actually 083 motors. The cylinder block of the 21114 engine is 2.3 mm higher than the 2111, the piston stroke increased from 71 mm to 75.6 mm, due to which the volume became 1.6 liters. The environmental performance of the unit has also increased, it has also become more reliable, less capricious than the VAZ 2111 engine, there is an advantage in elasticity and high torque.
This engine has many names: 21114, 11183, engine 2114, viburnum motor. The differences between the VAZ 21114 engine and the VAZ 11183 are that they are assembled in different places of the plant, physically the engine is one. The names of the 2114 engine (1.5 liters were also called so), as well as the viburnum engine, have taken root among the people.
The engine itself is an in-line 4-cylinder injection engine with an overhead camshaft, the gas distribution mechanism has a belt drive. The resource of the VAZ 11183 (21114) engine, according to the manufacturer's data, is 150 thousand km, in practice the motors run more than 200-250 thousand km. there are cases up to 300 thousand km.
Owners of four cars and other cars with this motor often ask themselves a question, does the 21114 engine bend the valve? The answer is simple: if the timing belt breaks the valve, your engine will not bend, but with a sporty evil camshaft there is a chance.
Among the shortcomings, it is worth noting the requirements for periodic valve adjustment, as well as the noise of the engine, reminiscent of a diesel engine. About noises and knocks, they are, in addition to them, the engine troit, heats up or does not warm up, etc., you can read about the causes of this or that problem.

Tuning of the engine VAZ 11183 (21114)

Consider the potential of 11183 8V motor without replacing the cylinder head with a 16 valve (124 motor and its modifications are mentioned in a separate article)
The easiest way is to replace the camshaft with OKB Dinamika 108 or Nuzhdin 10.93, install a split gear, adjust the phases with this, we will get about 85-90 hp. and a bouncy pick up at the top. We do not skimp on a receiver, a 54 mm damper and a 4-2-1 spider exhaust, this config will go better than a 16 valve 124 engine, while the cost of revising a VAZ will be quite mundane. The revision of the cylinder head and intake manifold, light T-valves and cylinder head milling will allow us to squeeze the maximum. The approximate power of the VAZ 21114 engine in this case will reach 110-115 hp. Let the motor spin more easily, maybe a light piston piston, put it on and get 120+ hp.

Compressor for viburnum motor

An alternative method of obtaining such an output is to install a PK-23-1 compressor, and to increase its efficiency we add Nuzhdin 10.42 or 10.63. The well-known video explains everything that is required for the successful implementation of the project.

Attention MAT (18+)

It is possible to increase power without using a turbine up to 170 hp. and higher, but the resource of the VAZ 11183 engine is significantly reduced.The right step would be to increase the potential by increasing the efficiency of the engine, namely by installing a 16-valve cylinder head, which, together with a valve, a receiver and an exhaust on 51 pipes, will give 110-120 hp. without significant loss of resource.

Turbo viburnum motor

The configuration of a turbo engine based on an 8-valve cylinder head is described, the principle is the same.

The valve mechanism works as follows: at the moment the piston reaches top dead center, both valves in the combustion chamber are closed - a certain pressure is created in it. Broken belt leads to the fact that valve do not have time to close in time before the arrival of the piston. Thus, their meeting occurs - a collision, which directly leads to the fact that the valve bends. Previously, in order to prevent such a problem, special valve grooves were made on older engines. On engines of the new generation, similar recesses are also found, but they are intended only to avoid deformation of the valves during engine operation and, if a belt breaks, they absolutely do not save.

From a physical point of view, from the moment the timing belt breaks, the camshafts instantly stop, under the action of the return springs that brake its cams. At this moment, the crankshaft inertia continues to rotate (regardless of whether the gear was engaged or not, the speed was low or high, the flywheel continues to turn it). That is, the pistons continue to work, and as a result, they hit the valves that are currently open. Quite rarely, but it happens when the piston itself is damaged.

Causes of a broken timing belt

• wear of the belt as such or its poor quality (shaft gears have sharp edges or oil ingress from the oil seals).
• crankshaft wedges.
• the pump wedges (the most common occurrence).
• wedge several or one camshaft (for example, due to the failure of one of them - however, the consequences here are slightly different).
• the tension roller is unscrewed or the rollers are wedged (there is a loosening or a tightening of the belt).

Modern engines, since they are more powerful in comparison with their predecessors, have much lower survivability. If we consider the cause, relying on the valves, this problem arises due to the small distance between them and the piston. That is, if at the moment the piston arrives, the valve is slightly open, then it instantly bends. Since for greater compression and compression in the bottom of the piston there is no groove for the valve of the required depth.

On which engines does the valve bend?

On cars with an 8-valve engine, it bends less often, but 16 and 20 grade, be it gasoline or diesel, bend occurs in most cases. True, sometimes it can be one or more valves, and if the engine was idling, then the trouble will carry over. But such cases are few, in general, the consequences are irreversible. A table with a list of engines on which the valve of all popular cars bends when the timing belt breaks.

How to find out if the valve bends?

Checking the engine is there a risk of bending the valves after a timing break

In this matter, neither a visual inspection nor the numbers given in the "valve bending" tables will help you. Even if you have information from the manufacturer about damage in the event of a belt break, it is not known how reliable it is.

If you want to check for the likelihood of the valve piston bending when the timing belt breaks, you must remove the belt, set the first piston at TDC, turn the camshaft by 720 degrees.

If everything went well and he did not resist, you can continue checking - go to the second piston. When everything is normal there, then a possible belt breakage will not lead to negative consequences for your car's engine.

To avoid this problem (bending of the valves in case of breakage), it is necessary to constantly monitor the condition and tension of the timing belt. When the slightest unfamiliar noise appears during operation, you must immediately try to find out the cause of its occurrence, inspect the condition of the rollers and the pump.

When buying a used car, do it immediately regardless of what the seller told you. And then such an urgent question as Does the valve bend at a break You will not be disturbed.

Bent valve signs

When the belt broke, then simply changing the timing belt, hoping that everything went without consequences and you start the engine, is not worth it. Especially if the engine is on the list of those on which the valve bends. Yes, there are times when the bend was not large and several valves have ceased to fit snugly in the saddle, then you can turn with the starter, but often such actions will aggravate the situation even more. Since with minor damage everything will work and spin, however, the engine will shake, and the consequences will only worsen.

Best of all, if you remove the "head" in order to check it visually or kerosene fill, however, there are several ways to check if the valve is bent without disassembling the engine.

The main symptom if the valves are bent - small or completely no compression... Therefore it is necessary in the cylinders. But, such actions are relevant if the crankshaft can be cranked and nothing rests on anywhere. So the first thing to do is to install a new belt, manually, using the bolt on the HF, turn the entire gas distribution mechanism a few turns (you need to unscrew the candles).

How to check if the valve is bent

To determine if a valve stem is bent, literally five turns of manual cranking with a wrench for the crankshaft bolt will be enough. If the rods are intact, then the rotation will be free, bent - heavy. And there should also be clearly perceptible 4 points (at one revolution) of resistance to the movement of the pistons. If such resistances are imperceptible, then after screwing back the candles, unscrew them in turn and turn the crankshaft again.

Due to the force of manual torsion, with one of the candles missing, it is relatively easy to understand in which particular cylinder the valve (s) were bent. However, this method will not always be able to help you know exactly whether the valve is bent or not.

If the crankshaft turns freely, then you can check with a compressometer... No such tool? Means do a pneumotest, moreover, checking the tightness of the cylinders is the most correct way, which will give an answer as to how the valve discs fit in the seats, without additional consequences when cranking with the starter and without installing a new belt.

How to check if the valve is bent yourself?

For a pneumatic test, it is unnecessary to pull the car to the service station, you yourself can find out if the cylinder is sealed or not. The easiest way is:

1. select a piece of hose according to the diameter of the candle well;
2. unscrew the candle;
3. set the cylinder piston to top dead center (valves closed) one by one;
4. insert the hose tightly into the well;
5. try with all your might to blow into the combustion chamber (air passes through - bent, does not pass - "blown").

The same test can be done using a compressor (even a car compressor). True, you will have to spend a little more time, since you need to prepare. Drill a central electrode in the old candle, and put a hose on the ceramic tip (fixing it well with a clamp). Then pump the pressure into the cylinder (provided that the piston in it is at TDC).

From the hiss and the pressure on the pressure gauge, it will be clear whether the valve hats are in the seats or not. Moreover, depending on where the air will go, determine the inlet bent or outlet. When the exhaust outlet is bent, air goes to the exhaust manifold (muffler). If the intake valves are bent, then in the intake tract.
