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.

WHAT ENGINE DOES A VALVE, AND WHAT DOES NOT!
WHICH ENGINE VALVE BELTS, WHAT NO - in this video I show how, without delving into any technical.

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 ...
Greetings to you friends on the do-it-yourself auto repair site. Experienced motorists know that a broken timing belt can lead to dire consequences. In particular, there is a great risk of "meeting" the valves that have already come out of the seats and the pistons rising by inertia.
The result is the deformation of the vital elements of the motor, as well as an urgent need to visit the service station and carry out major repairs. But does the valve always bend when the timing belt breaks? Should I be afraid of this?
A bit of history
On the new "tens" 8-valve engines with volumes of 1.5 and 1.6 liters were immediately installed. The first power units (from the point of view of the problem we are describing) were ideal, and the valves did not bend. Although on earlier models of the type eight, nines with a volume of 1.3 this problem was. The reason was that the piston constructively could not "meet" the valves.
Over time, a more modern model VAZ 2112, equipped with a one and a half liter engine, with a 16-valve engine, appeared in the “dozen” family. It was from this moment that the problems began. Many motorists and specialists could not understand why the valve was bending.
In fact, the reason was in the design of the power unit. On the one hand, the appearance of a 16-valve head made it possible to increase the power of the car to 92 "horses", and on the other - broken timing belt invariably led to collision of pistons and valves, as well as deformation of the latter.
After that, I had to go to the service station and hand over the car for expensive repairs. The constructive fault lay with the pistons themselves, which lacked the necessary recess. As a result, a timing belt break always ended in the same way.
Updated car engine
A similar oversight was adopted and more advanced 1.6-liter 16-valve engines were installed on the new VAZ 2112 cars. Structurally, the power units did not differ much, but one feature was still present. In the new engine, the pistons had certain notches, so the problem described above was eliminated.
Over the next few years, motorists began to forget about bent valves and got used to the reliability of the new 16-valve motors. But the updated Priora model with a 1.6-liter power unit was unpleasantly surprised - the valves also bent when the timing was broken.
At the same time, the final repair was much more expensive. On the other hand, the developers made the belt as wide as possible to minimize the chance of belt breakage. Only those motorists who got a defective belt or those who did not watch their "iron horse" were unlucky.
Unfortunately, even on the new 1.4-liter Kalina engines with 16 valves, repairs cannot be avoided if the belt breaks in motion. So monitoring the status of this node is mandatory.
On which VAZ engines the valve bends, and on which not
Let's draw intermediate conclusions, as well as highlight the most "dangerous" and "safe" models from the standpoint of the likely deformation of the valves in case of belt damage:
1. What kind of engine valve bend? This category includes motors of cars of the following model range - 21127, 21116, 2112, 1194.
2. What kind of VAZ engine does not bend the valve? Motors of such VAZ models as 1183, 21114, 21083, 21124, 21126 (bent until 2013, and now not), 21128 are more reliable.
The current problem has caused a lot of controversy among motorists. Many owners of "problem" VAZs are interested in what to do so that the valve does not bend. In fact, there are several recommendations.
They are as follows:
1. First, try to periodically assess the condition of the timing belt and replace it at the first sign of damage. The appearance of cracks, contact with the surface of engine oil, excessive stretching, peeling of the edges - all this is a reason to install a new timing belt and not wait for a rupture.
2. Secondly, if the engine is expected to be repaired, you can change the pistons, and in some cases the crankshaft. In addition, some experts recommend (as a way out) the installation of a new camshaft.
But here, of course, one cannot do without consulting specialists. After that, you may need to flash and remove the catalyst.
If you got a car where the valve bends, then do not despair ahead of time. The ideal solution would be maximum attention to the engine and more frequent timing belt replacement... Even that will be enough to keep the risks to a minimum.
As for the replacement of units and expensive repairs, these costs, as a rule, do not justify themselves. Good luck on the road and, of course, no breakdowns.

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.
don_gbekoneSo, we all know the story of our friend about an unpleasant incident on the road.In short: while driving along the Moscow Ring Road, the timing belt on his car broke. He caught a tow truck, which took him to some kind of car service.
The tow truck driver was "on the way" and he offered to take the car to "his" service for only 1000 rubles. It would have cost 2,000 rubles to take the car to my friend's house (although it is 10 minutes longer than to Anino). The service told him that the timing belt was torn and he left the car there for diagnostics until the next day. The price of the "diagnostics" was not named, of course.
I will say right away that the decision to go to this particular car service may cause misunderstanding and disputes among some people.
Firstly, the contingent of owners and service workers consisted of people from the southern republics who are actively helping us to live in central Russia. Some treat them without any suspicion, because the fame of honest, friendly and hardworking people is firmly attached to them. Don't you agree ???
Secondly, I can't imagine how you can catch a tow truck on the Moscow Ring Road at 7 am on the road (without calling it in advance by phone).
However, for some reason, many people avoid dealing with such services.
But the continuation of the history of codeforfood for some reason did not finish.
Somewhere he will correct me, but from his words everything looked like this:
the next day he received a call from the service and was told that they had carried out a diagnosis. It was reported that the valve was bent and, as a result, the engine was to be overhauled (50-70 thousand).
Since we mainly service our cars with one reliable and experienced master-private trader, Uncle Kolya (who specializes in engines), he decided to pick up the car and consult with him. We, as naive people, discussed all this in his topic and did not understand why he didn’t do it right away or didn’t take the car to his yard.
It was expensive to call a tow truck, and he came with friends in another car to tow the broken car with it.
Roughly such a picture appeared before his eyes: the engine was disassembled, removed (damn it, but in general it is difficult to pull it out without special equipment, and if the bridge interferes with the bottom, then they pull it over the top) and lay in the trunk. They demanded 8000 rubles for the "diagnostics" (!!!). To do this, you do not need to remove the engine, disassemble it, Uncle Kolya would diagnose it for a maximum of 500-1000 rubles. I had to pay and tow the car to the house.
What was 9000 rubles paid for? For simply being told: "the valve is bent" and the engine disassembled? What the fuck is it to disassemble and pull out for this? It became clear to me that this is pure divorce. Maybe the valve is not bent there at all (on some types of cars this does not happen when the timing belt breaks). We will soon find out.
But unexpectedly, from a friend of mine at work, I learned his story, which is like two peas in a pod similar to the story of codeforfood.
His uncle is a very experienced person in the auto repair business. His friend (by the way, an Armenian) called my uncle and said that he was being bred in a service in Anino and needed help. Uncle told him if he was a normal person, that he went to this service, as he had a very bad reputation.
The scheme is about the same. He was standing on the Moscow Ring Road, a tow truck picked him up and offered to take him to the service in Anino. They insisted that he leave the car for the night (like we are already closing), in the morning they called him and said that something needs to be replaced - the price is 10,000 rubles. When he arrived to see the car, the engine was already disassembled and lay in the trunk (damn, what kind of style is that - to disassemble the engine and put it in the trunk). He agreed. Then they called him the next day and said that they had identified some other malfunction. The total price will be 35,000 rubles. When he came to pick up the car, it turned out that he owed 35 thousand plus 10 thousand, and if he did not agree, then the engine had to be assembled, and that would also cost money. In short, the pumping out of money began. After that there was a call to a friend, a support group of 5 people arrived, a difficult conversation took place, the car was returned with an apology, while trying to get out of the situation "nicely" - like in the movie "Boomer", when the main characters meet and disagree with the local group.
My uncle told my friend that this service is "razvodilovskiy". It looks decent, but they are not doing repairs there, but by bugging, sabotaging and siphoning money. There is also something like a car market, a spare parts market, etc.
The scheme is simple - their tow truck runs along the Moscow Ring Road in this area, notices cars standing on the side of the road and convinces their owners to take the car to this service. Then what I wrote above begins. I'll find out the exact address later, leaving it through a gas station. There is a fairly large service, but it belongs to people from the same republics and the scheme of work there is also the same.
A little googled "car service in Anino" and came across similar stories.
Be vigilant, do not let yourself be screwed. In such places, not a foot. Don't feed these devils.

Continuous improvement of the internal combustion engine in order to increase and improve fuel efficiency forced engineers to seriously redesign the design of modern diesel and gasoline engines. The changes also affected the device of the piston group and the combustion chamber. These modifications were made for the most efficient filling of the cylinders and their high-quality ventilation, that is, to obtain improved gas exchange.
If in the early stages of development the most common was the engine with two valves per cylinder (1 inlet and 1 exhaust valve), today there is an increase in the number of valves per cylinder. Such changes are well illustrated by the most common version of the automobile with four cylinders. Previously, such motors were often 8-valve, with one. Today, such a unit is often a 16-valve version with two camshafts (for intake and exhaust valves), can be equipped with a variable valve timing system, etc.

Broken timing belt / chain: main causes
If we compare modern motors with their predecessors, today motors have more power and less resource. As for the problem of bending the valves, it is precisely to achieve greater recoil from the motor that the distance from to is minimal. Even a slightly open valve bends during the lift of the piston at TDC. It turns out that various technical innovations in engine building did not in any way affect the well-known problem that is inherent in the vast majority of engines, regardless of the type of engine and manufacturer. We are talking about the bend of the valves when the drive belt breaks or.
An important rule during the operation of the car is to monitor the condition of the timing belt and its timely replacement. The belt must be free of delamination, cracks or other defects. Also, it is not allowed to get various technical liquids on its surface. The appearance of a squeak, squeak and other extraneous sounds will require the owner to check the tension and condition, as well as the tension and other rollers.
To answer the question when you need to change the timing belt, you need to study the operating instructions for a particular car. Often, on new cars, the belt changes after 60 thousand kilometers traveled or after 2-3 years (whichever comes first). A planned replacement with an original belt involves the next replacement every 50 thousand km. It is advisable to choose non-original belts with care and change every 40 thousand km.
Now a few words about the chain drive. The timing chain requires less attention, since the replacement of the chain is, on average, necessary once every 150-200 thousand km. and more. In this case, it is necessary to monitor the chain tension, the condition of the tensioner and the chain damper. Increased noise during engine operation, the appearance of a metallic clang and other signs will indicate the need for an immediate check of these elements.
So, back to the less reliable belt in comparison with the chain. The timing belt most often breaks for the following reasons:
- belt wear as a result of prolonged use or the use of a poor quality product;
- jamming (water pump);
- wedging of the crankshaft, camshaft;
- malfunction of the tension roller, jamming of the timing rollers;
- destruction of the timing belt as a result of engine oil getting on its surface;
- mechanical damage after contact with sharp edges, camshaft gears;
Why do the valves bend when a belt or timing chain breaks
Despite the improvements, the general traditional principle of operation of the timing and valve train of the engine remains unchanged. As you know, raising the piston at TDC (top dead center) means that at the specified moment the valves are also closed. This is necessary to create pressure and seal the combustion chamber.
If the timing belt breaks, then the valves simply do not have time to close, which means they collide with the piston rising up. When the timing belt breaks, the camshafts stop immediately. This immediate stop occurs for two reasons:
- since the driving force from the belt or chain disappears;
- the camshaft cams themselves are retarded by return springs;
As for the crankshaft, this element continues to rotate by inertia. The inertial rotation of the shaft does not depend on what gear and at what speed the car was moving, at what speed the engine was running, etc. turns the crankshaft anyway. In other words, if the timing belt is cut off, then the gas distribution mechanism stops immediately and the valves remain open, while the crankshaft continues to rotate and the moving pistons hit the open valves at this time.
The result of a broken belt is that the piston meets the valves, after which the valves are immediately bent. The valve stem is often bent, although sometimes various deformations of the valve disc are also possible. Less commonly, damage to the piston itself can be found, which is also a consequence of a belt break and bending of the valves.
Engineers and automakers are familiar with this problem. To prevent the consequences of breaking the timing belt / chain in some old ICEs, special grooves for the valve were made on the piston. These grooves actually provided the necessary free space, which allowed the open valves not to collide with the upward moving piston. In such motors, after a break in the drive, the valve did not bend.
Modern engines also have distinctive piston notches. It should be noted that these grooves avoid the risk of damaging the valve while the engine is running. If the timing belt breaks on such motors, these grooves do not save from bending the valves, that is, the valve still bends even if there are special grooves on the piston.
On which engines the valve bends: how to find out
Due to the severity of this problem and the high cost of subsequent repairs, many motorists are concerned about the question of how to find out if the valve motor is bending or not bending when the timing belt breaks. To more accurately find out and determine whether the valves bend on a particular engine, you can use the following recommendations:
- Study in detail the technical documentation for the engine from the manufacturer. We add that a visual inspection, as well as various data from the tables, still do not give 100% certainty that when the drive belt breaks, the valve does not bend. It is also not recommended to blindly trust the statements on specialized auto forums or rely on information from other more or less authoritative sources. In other words, the validity of any data must be questioned and rechecked.
- Another method is the so-called "physical" check, which allows you to find out yourself if the valves are bent. This method allows you to determine the likelihood of valve bending, that is, to confirm or deny the possibility of contact between the valve and the piston.
In order to find out whether the valve is bending or not bending, you will need to remove the timing belt. Further, the piston in the first cylinder is set to the TDC position, after which the camshaft of the gas distribution mechanism is rotated 720 degrees. If no stop is observed during the camshaft rotation, then it is necessary to make a similar check by alternately raising the pistons in all other ICE cylinders to TDC. If the camshaft does not rest anywhere, then there is a high probability that the valve on this engine will not bend when the belt breaks.
As for the various technical information, which is given in the tables, as well as referring to the experience of auto mechanics and ordinary drivers, the summary data allows us to note:
- often the valve does not bend on simple 8-valve motors;
- usually valves bend on 16-valve and 20-valve engines;
- valve oppression on almost all diesel engines;
- bending of the valves occurs on most engines in the event of a break in the timing chain, that is, on engines with a timing chain drive;
- valves usually bend on engines of small cars with a displacement of 1.1 to 1.4 liters;
