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.

A rather relevant question, on which VAZ engines does not bend the valve, will probably interest every owner of a car from a legendary domestic manufacturer - old or new - without much difference. The fear of a belt breaking in some drivers even turns into a kind of paranoia: they begin to carry a spare belt with them, study the state of the worker at every opportunity, consult with all friends and acquaintances who have anything to do with the car business. But can such actions always lead to the planned result?

On which VAZ engines does not bend the valve, you need to know for sure, and these data will strengthen you in understanding: will you have to repair, apart from replacing the belt when it breaks, the engine as well? After all, this procedure can take a lot of effort and, most importantly, money.

A bit of history

It is not difficult to remember engine modifications on models. But all in order! The first were 8-valve engines (1.5 and 1.6 liters). The valve did not bent on them. And all - for a simple reason: the pistons in the intended design did not occur in the event of an incident with valves.

The developers bypassed the potential problem quite well, honor and praise for it (how many this feature saved from unplanned and rather expensive repairs)! A little later, a new motor for those days.

With all the improvements and increased horsepower up to 92(from 76), which was a clear plus, this motor also had some, not immediately noticeable shortcomings. The design of the mechanism has been changed thanks to a new head (16-valve). And as a bonus - the meeting of the pistons with the valves in the event of a break in the timing belt (at the most inopportune moment, as a rule)!

As a result- the valves are bent on this model unambiguously. And the car owner was expected by quite expensive repairs, which cost a pretty penny. The reason, in addition to breaking the belt, is simple - the very design of a 1.5-liter engine with 16 valves: the pistons do not have special under-valve recesses and, as a result, they hit the valves hard. There is a bend of these parts, popularly called: the valve is bent.

Correcting errors: But now a few years have passed, and the designers have revised their concept. At 2112, new 1.6-liter engines were installed, also 16-valve ones. In these modifications, little has changed from the previous ones, but there were recesses for valves on the pistons, which made it possible to avoid the meeting of these parts in the event of a belt break, and therefore expensive repairs.

All repeats

Not so many years have passed, the happy owners of these VAZ models have already begun to get used to the good. To the fact that when the belts break, the valves on the engine do not bend, injuring it from the inside. But it was not there! The domestic auto industry does not allow you to relax even for a minute. The Priora (updated ten) appears on the horizon, a seemingly modern machine, quite decent for many. Engine - 1.6 liters, 16 valves. Motorists thought that such annoying flaws would not happen to him.

However, as practice has shown, if the belt breaks on the Priora, the valve still bends (that is, they also meet with pistons, as in the very original 16-valve mechanisms). And who needs it, one wonders: an additional fix for the present times, costing a pretty penny? After all, the repair of the Prior's engine will cost even more than that of the usual dozen.

One good thing is that the likelihood of such a flaw is still reduced by the designers to a minimum: the belt is much wider and it does not break so often. But sometimes it breaks! Or, for example, a defective spare part may come across, and the likelihood of a rush will increase significantly. What to do then? We'll have to repair the engine, and not just install a new belt. Because it is not possible to predict when this may happen with hidden defects.

It remains only to make a wish so that this breakdown does not occur somewhere in an open field, where cars do not pass often, but in the city with the ability to tow your car.

By the way, on Kalina they also install engines similar to the methods of destructive action on the valves, only 1.4 liters (16 valve). So, as they say, be vigilant and know: on which engines the VAZ does not bend the valve, and on which - bends! There, you will have to constantly monitor and check the condition of the belt and take preventive measures to prevent timing breaks.

Car owners faced the problem of valve bending even on the first G8 models. The engine installed on them, with a volume of 1300 cc, bent the valve when the belt broke.

This problem is associated with several reasons, such as jamming of the pump and tension rollers, wear or poor manufacturing of the timing belt (timing).

At the moment the timing belt breaks, the camshaft stops in the position in which the breakage occurred, and the crankshaft, continuing to rotate, pushes the pistons towards the open valves. As a result, they collide, leading to damage to valves and pistons.

In such a collision, it can damage not only the pistons, but also the cylinder walls and connecting rods. In this case, car repairs will be very costly and time consuming.

On some types of engines of VAZ cars, this was avoided. In such engines, special recesses for the valves are molded on the pistons, so if the belt breaks, a collision does not occur.

Several types of engines were installed on the Lada. Let's look at which of them are dangerous and which are safe and why the valve bends on Kalina when the belt breaks.

Types of engines affected by this problem

1. The eight-valve, model 21116, with a volume of 1.6 liters, is equipped with a lightweight piston group. Due to the lightening, the pistons became very thin and there was simply no room left for the valve casting. When such pistons collide with a valve, the entire piston group usually suffers.
2. The sixteen-valve, model 21126, with a volume of 1.6 liters, is installed on the more expensive Kalina class of cars. On this engine, piston-valve collision is also inevitable.
3. The sixteen-valve, model 11194, with a volume of 1.4 liters, is one of the most economical, but, unfortunately, it is also susceptible to this problem.
4. Sixteen-valve, model 21127, with a volume of 1.6 liters. This is a new engine based on the previous model 21126. Installed recently. It is more powerful, but it also remains on our list of "dangerous".

Engine types not affected by this problem

1. The sixteen-valve, model 21124, with a volume of 1.6 liters, is considered one of the most reliable. Installed on the twelfth model of the Zhiguli. With this engine, you will not have any problems with the gas distribution mechanism.
2. Eight valve, model 11183, 1.6 liter, proven engine, distinguished by its reliability, ease of maintenance and availability of spare parts. Also falls into the category of safe.

A few tips on how not to find out if the valve is bending on Kalina and not to get expensive repairs

In order to try to avoid damage to the gas distribution mechanisms, it is necessary to replace the timing belt in a timely manner.

It is not enough to change one belt. Be sure to change the tension rollers with it and monitor the condition of the pump. If necessary, it must also be replaced.

In no case do not skimp on spare parts. Choose your timing belt carefully. It should not have any irregularities, stripes or seams.

When buying a water pump and idler rollers, choose only well-known and trusted manufacturers.

Observing these simple rules, you will never know whether the valve bends on the Kalina car, and how much the engine bulkhead costs.

Hopefully, this article will help you avoid problems, usually associated with an oversight of the technical condition of the car. With the right attitude to the operation of the elements of the gas distribution mechanism, such problems should not arise.

The automotive industry knows thousands of engine options that are not very pleasant to operate. In particular, on such power units, when the timing belt breaks, the valves are bent, which meet the pistons in a chaotic inertial motion. The bending of the valves will have to be treated by replacing them, as well as by rebuilding the entire upper part of the engine. It will cost the owner of even an inexpensive domestic car more than 15,000 rubles. Therefore, if there is such an opportunity, it is better to choose power units in which the valves do not bend when the belt breaks. Today we will consider domestic developments in the field of engines for cars. It turns out that in this regard, the engines on domestic cars were quite adequate. Many of them did not know such a problem as bent valves for various problems.

In general, AvtoVAZ has designed quite interesting power units. Yes, most of them had less potential and consumed a lot of fuel. But in fact, it turned out that the engines did not require any maintenance at all. They just served for years without causing any problems or negative situations. In many units, even the oil was not changed, pouring 30-40 thousand cheap mineral water once, which could be obtained during the Soviet Union. So it is not worth scolding the engines of the first VAZ models, up to the VAZ 2108 and 2109. It turns out that this was the best time for the domestic auto industry, which showed the maximum potential and the minimum of problems in use.

VAZ engines from 2101 to 2106

Often, VAZ used the simplest technologies in old cars. The developments of the 70s of the last century served in fact until recently, because the latest version of 2106 was taken out of production just a few years ago. It is very interesting that there were engines throughout the entire range of these cars, which received many important advantages in operation:

• power units often had 8 valves, as well as places for folding them in case of problems;
• the timing belt or chain was of quite high quality, it went 50-60 thousand kilometers (or more than 200 in the case of a chain);
• the engines worked in all weather conditions without problems, received a lot of positive feedback from experts;
• some export cars have become popular in highly civilized countries around the world.

At the time of development of each of the VAZ cars in the range of 2101 - 2106, the transport was simply amazingly good. Even today, after 40 years from the release of some models, you can find cars in the secondary market with engines that will never bend the valve, and the power unit is not afraid of other problems. These are the features of the old VAZ developments.

VAZ 2107 engines with timing chain

Most of the VAZ 2107 power units, including all the latest engine modifications, had special timing chains, which serve quite adequately and do not fail for years. You can drive about 200-250 thousand kilometers on one circuit, then replace it simply because the motorist's conscience began to remind of maintenance.

It is important to remember that if the chain starts to give out some unpleasant sounds, it should be changed at that very moment. But even if the chain breaks, most modifications of the VAZ 2107 engine will not cause the valves to bend. Therefore, the owner of this car can be completely calm about the safety of the engine of his car.

VAZ 2108 and VAZ 2109 - a whole era in Russian cars

Hatchbacks, which were popularly called "Chisels", gained fame as reliable and durable cars, they were produced until our time, they were assembled in Ukraine for several years, but have completely lost the relevance of their appearance and technology. Today you can buy on the secondary market an excellent version of the "Nine" of a completely fresh year of release in perfect condition. The engine in this car has the following features:

• there were in the history of the model a power unit for 1.1, 1.3 and 1.5 liters with a carburetor, as well as a 1.5-liter injection unit;
• all engines were protected from the influence of the timing belt rupture, the valves in the power unit did not bend;
• the car had quite adequate engine reliability - this unit was the last one to break in the car;
• all competitors presented at one time were scattered with advanced design, excellent comfort and other benefits.

At the very beginning of their production, VAZ 2109 and 2108 cars were a real revolution in the domestic automotive industry. Buyers of such cars have become real lucky people in the eyes of acquaintances and friends, exactly the same as buyers of the latest Mercedes models today. And there were certain logical reasons for this, such as the incredible reliability of the main nodes.

VAZ 2110 - "Tenth" family and new problems

"Dozens" in the VAZ model line appeared a long time ago, but they gained popularity in 1998. Ten years later, they were taken out of production, giving way to novelties of domestic development. Today "Ten" is considered to be quite adequate transport with certain problems in assembly. On these models, the engines were installed different and they had different characteristics:

• The 1.5-liter 8-valve simple powertrain did not bent the valve, but showed only 72 horses of power;
• a modified 1.5-liter engine with 16 valves began to actively bend these same valves;
• a more modern 1.6-liter power unit in an 8-valve version of the valve should have spared, but it did not;
• you will also not wait for a cheap repair after a timing belt break on the most powerful 1.6-liter 16-valve engine VAZ 2110.

The entire family of "Tenth" models was quite high quality and reliable, but the further the plant tried to keep up with the power, modernity and relevance, the more trouble the car got. The most durable and high-quality engine was 1.5 with 8 valves and 72 horses, but the latest models with powerful 16-valve units received only problems, judging by the reviews of car owners.

The modern era of VAZ engines - the main problems

For Lada Kalina, the lineup of power units was slightly modified. This car became the first in the family of a new generation of VAZ, received all engines that bend the valves when the timing belt breaks. Lada Granta also received three types of power units that actively bend the valve. All budget VAZ power units in a modern version of the valve are bent. Priora and Largus offer the following types of engines:

• the base Priora engine is a 98-horsepower power unit, the only one that spares the valves in the modern VAZ model line;
• the second power unit has the same design, but 106 horses, and these extra 8 horses will cause the valves to bend;
• 1.6-liter 8-valve engine of French origin on the Largus does not bend the valve;
• but his twin brother with 16 valves actively bends them when the timing belt breaks and mercilessly turns the upper part of the unit.

These are the contradictory and unusual characteristics in modern cars of the VAZ concern. But do not forget about one more important company representatives. The Lada 4x4 car offers a good 1.7-liter power unit with 8 valves, which has protection against kinking of these same valves. The unit, though not too powerful, is quite reliable. We offer you to watch a small overview of VAZ engines with recommendations for their operation:

Summing up

VAZ cars can hardly claim the title of optimal and best solutions even in their price range. But today, Granta or Kalina are often the only possible purchase for a Russian family. The sharp increase in prices for other new cars is responding to the need to buy specifically domestic developments. It should be noted that AvtoVAZ is carrying out colossal work on updating its equipment, but even such work has not yet yielded the desired results.

In modern VAZ lines there is only one own engine that does not bend the valve. This is a 98-horsepower unit on the Priora. However, everything here is arranged in such a way that you may not be lucky, so 16 valves will have to be changed after the belt breaks. In other engines, valves and other parts will have to be changed unambiguously after a belt break. It is much cheaper to monitor the condition of the roller and belts by replacing all these parts in a timely manner.

One of the scary topics in the conversations of motorists is why the valves bend, on which cars this breakdown is possible, and how to prevent it. Today we will tell you in detail about the reasons why the engine valve fails and the preventive measures for this malfunction.

What are the valves in the motor responsible for?

First, a little theory. Surely every car enthusiast knows how many cylinders there are in the engine of his car, but how many valves it contains - not everyone will give an answer to this question. In most modern engines, there are from eight to sixteen valves (two or four per cylinder), there are power plants (eight or twelve-cylinder), in which the number of valves is from 24 to 32.

The valve is an important part of the gas distribution mechanism (timing) of the engine of the machine, which is located in the cylinder head, is responsible for the timely supply of air to the cylinder and the displacement of exhaust gas from it.

Moreover, the same valve cannot perform these functions, and therefore each cylinder is equipped with two types of valves - intake valves, which supply air to the combustion chamber, and exhaust valves, which squeeze out the combustion products of the air-fuel mixture from this chamber.

There are engines in which there are two exhaust and intake valves per cylinder, and there are those with more intake valves than exhaust valves (three and five-valve cylinders). In the structure of the valve, two parts are distinguished: a plate and a stem. It is the valve stem that gets hit when one of the elements of the gas distribution mechanism fails.

The valves are brought into operation by the camshaft, which, rotating around its axis in the cylinder head, raises some and lowers other valves into the cylinders - these are the so-called gas distribution phases. In turn, the camshaft drives the crankshaft - both of these timing elements are interconnected by a drive, which can be a toothed, belt or chain drive. A gear drive rotates the camshaft in the cylinder block, and a belt or chain drive rotates in the cylinder head.

Currently, the most widespread are engines, in the gas distribution mechanism of which they are used. The belt drive type is simpler in design, but less reliable than the chain drive. The chain type of drive, in turn, is more complicated - its mechanism includes tension rollers and dampers. It is no coincidence that we paid so much attention to the details of the gas distribution mechanism - understanding the principle of its operation will help us in the future to determine the reasons why the valve bends.

Why valves bend

For both a belt-driven gas distribution mechanism and a chain-driven timing mechanism, there may come a moment when a belt or chain drive fails. A break in the timing belt or stretching of the timing chain links that are unable to catch on the teeth of the camshaft gears (slipping) leads to the fact that the camshaft stops abruptly, and the crankshaft continues to move.

At this moment, the valves are recessed into the cylinder, and the piston rises towards them. The lifting force of the piston is much greater than that of descending valves, so the piston hits the valve disc, and the rod, unable to withstand this impact, bends or even breaks. There is a complete stop of the engine, which is not recommended to start again, so as not to provoke more serious damage - failure of the pistons, which is fraught with expensive repairs to the cylinder head.

How to tell if the valves are bent

It is impossible to establish by eye that when the belt breaks or the timing chain slips, the valve is bent. To do this, you need to carry out two simple operations.

To begin with, we will install a new timing belt on the rollers according to the marks and slowly turn the crankshaft. Two to five revolutions are enough to determine that the valves are bent: if the rotation is free, then the valve stems are intact, if it is difficult, the valves are bent.

It so happens that the crankshaft turns, but the valves are still bent. How, in this case, to determine the breakdown? It is necessary to measure, having previously unscrewed the spark plugs. If there is no compression in the cylinder, the valves are bent.

How to prevent valve breakage

Let's analyze the reasons why the belt could break in order to understand how to prevent such a breakdown.

Cause 1. The timing belt has expired. Like any other consumable, the timing belt has its own service life. The car manufacturer in the operating manual indicates the timing of the timing belt replacement - for most engines, it occurs with a mileage of 100-120 thousand kilometers. It is certainly possible to hope that until this moment the belt will serve faithfully, of course, but for greater fidelity, we recommend that at each scheduled maintenance inspect the condition of the belt and, if necessary, replace it. In this case, we will not allow it to break, and, as a result, we will not disentangle the problems with bent valves.

Reason 2. Using a counterfeit timing belt. Some motorists, wanting to save money, buy non-original, cheap timing belts, which break at low mileage - 5-7 thousand kilometers. Advice - be responsible for buying a timing belt, it is better to pay more for this consumable than to fork out for expensive cylinder head repairs later.

Reason 3. Breakdown of the timing pump. In the design of the gas distribution mechanism of some engines, the pump comes into contact with the belt, and if this unit fails, it jams, as a result of which the belt rubs against the pump and frays, which leads to its breakage. The pump wears out at the same mileage as the timing belt, therefore, when replacing the belt, we recommend installing a new pump.

Cause 4. Camshaft wear. This breakdown occurs at high engine mileage (from 150 thousand km or more), and therefore does not occur so often. A jammed camshaft can cause the timing belt to burst. That is why when buying a used car with high mileage, we strongly advise you to take a look at the condition of the camshaft.

Cause 5. Malfunction of the timing drive attachment. The timing belt moves on rollers, which can also wear out, jam, which leads to the belt breaking and the valves being bent.

Although engines with a timing chain drive are considered more reliable, it happens that they also have valve bending. This happens for two reasons: the chain links are stretched or the drive attachments (idler rollers and dampers) fail. The main reason why the timing chain links stretch is the poor quality material from which it is made. Such a disaster happened to Volkswagen engines in the mid-2000s: the German automaker ordered chains from an unscrupulous contractor, and they began to fail at 20-40 thousand mileage, provoking bending of the valves. To prevent such motors from bending the valve, you should periodically diagnose the timing chain and attachments and, if necessary, change them to new ones.

In addition to these methods, it is possible to prevent bending of the valves by making special recesses on the piston heads, which will correspond in size to the valve stems. If a belt breaks or a chain slips through, then when the camshaft stops, the valve rods will not bite into the piston heads, but will enter the grooves and stop there. True, this method also has its drawbacks: an engine with such "tuned" pistons loses up to seven percent of its power. Are you ready to derate the motor of your "iron horse" for the sake of the safety of the valves in case of failure of the timing drive?
