In the fall of 2015, the Lad family of passenger cars was replenished with a top model - the Vesta car, produced in a sedan body. When asking the question “do the valves bend on the Lada Vesta,” you need to clearly imagine what kind of engine we are talking about: a 1.6-liter Russian or Nissan, or maybe the latest VAZ development with the name “21179”.
Here we consider options related to cars currently being produced or those that will begin to be produced in the near future. An 8-valve engine was also developed for Vesta - it definitely does not bend the valves and will definitely not be installed on top-end sedans in 2016.

ICE VAZ-21129, 106 “hp” (valve bending)
Under the hood of the 106-horsepower Lada Vesta
A little history. Motor 21129 is a modified version of another engine, namely 21127. The last of them, when the timing belt broke, successfully bent its valves, although grooves were made on the pistons (Fig. 1). The point is that the depth of the grooves was not sufficient: if certain conditions were met, the valve “met” the piston with all the ensuing consequences.
With the transition to a new generation of internal combustion engines, that is, 21129, the design of the pistons was modified. But the external shape has not changed much, and although the recesses remain, their depth is still insufficient.
Here we considered the question of whether the Lada Vesta valves with the “21129” engine are bent. And the answer was unequivocal: yes, oppression.
In theory, the problem with valve bending is typical for all VAZ engines equipped with 4 valves per cylinder. Each new 16-valve engine “inherits” it. The exception is one rarity - the VAZ-2112 internal combustion engine, the volume of which is 1.6 liters. There, the recesses are made conscientiously (Fig. 2).
122-horsepower engine “21179” (valve bending)
In terms of its design, the internal combustion engine of the VAZ-21179 is not very different from its predecessors. The working volume was increased to 1774 ml, which was achieved by changing the piston stroke length: it was 75.6 mm, it became 84.0 mm.
Elements of the connecting rod and piston group
The piston itself is now fitted to the cylinder better than in engines 21127 and 21129. The distance from the piston pin to the piston crown has increased by 1.3 mm to 26.7 mm. But deeper grooves in the bottom never appeared. The timing mechanism still drives the belt, and if it breaks, the possibility of bending the valves has not been canceled.
Now we know whether the valves bend on a Lada Vesta with a 1.8-liter engine. The answer will be the same as for all 16-valve VAZ internal combustion engines (with the exception of 2112). The problem with the transition to a new generation remains the same. But VAZ does not intend to return to “heavy” pistons.
The timing drive on 21179 engines is equipped with not one, but two tension rollers. What was done to make the design less susceptible to timing belt stretching.
It says here: the number of tension rollers is two
One of the automatic tensioners may jam, but then its function will be taken over by the second automatic roller.
Pistons that do not bend valves
Piston kits for some “old” 16-valve engines are produced by third-party companies. These parts are equipped with deep recesses. The point is that the piston does not reach the plates and cannot bend the valves.
Tuning piston for internal combustion engines 21126-21127
ShPG elements of different engines (21127, 21129, 21179) are compatible. But there is no need to install pistons from “old engines” into the Vesta engine:
- In ICE 21129, after such “tuning”, friction losses will increase;
- If pistons from the 26th or 27th engine are installed in the ICE 21179, the working volume will immediately change.
The “29th”, as well as the “79th” Lada Vesta engine bends valves only with “VAZ” pistons. But after installing a “tuning” part, do not expect an increase in power. Also, by using non-standard elements, you can greatly reduce the resource (lose the warranty, get unforeseen consequences).
Nissan HR16DE engine (does not bend, there is a chain)
HR16DE engine disassembled
There are no “deep recesses” provided here. Now let's pay attention to how the timing drive mechanism works.
Nothing but gears and chains
There is no toothed belt here - it is replaced by a chain. It is difficult to imagine the following two situations:
- The chain could have jumped over the teeth of one or more gears;
- One of the elements was damaged so badly that the presence of damage led to rupture.
As long as the chain remains intact, the valves and pistons cannot meet each other, no matter what happens to the engine. The only bad thing is that the chain may jam.
Do the valves of a Lada Vesta with a Nissan internal combustion engine bend? The answer “no” would be wrong - a circuit break is not excluded. But in reality it will be almost impossible to face such a situation. Let's look at why.
Four Well-Known Facts
The service life of the timing chain always exceeds the service life of the engine. This is the first fact, but a condition must be met: the oil change must be timely. In general, the circuit fails gradually, and this is accompanied by symptoms:
- Audible sounds (chirping) at idle speed;
- When the “problem area” passes, a phase shift may be observed.
The last defect is detected using computer diagnostics.
From the appearance of any symptom to the complete rupture of the chain, a certain time passes. And in general, a “defective circuit” can work for a long time. This was another, fourth fact.
Consequences of a broken timing belt, video example
At the moment, Lada Vesta is produced with 2 engines VAZ-21129 (1.6 l.) and VAZ-21179 (1.8 l.). Previously, this car was also equipped with an 8-valve VAZ-11189 engine (1.6 liters). In the near future, it is planned to produce a car with the French-Japanese power unit Renault-Nissan HR16de/h4m. What is all this for? Yes, because the timing belt on the Lada Vesta is installed depending on the type of power unit.
The Renault-Nissan engine has a chain installed instead of a timing belt.
The part with the article number is installed on the 11189 engine 21080100604082 . Average price - 320 rubles. Manufacturer: Gates (Poland). The most popular belt replacement for this 8 valve engine is VT25009. Manufacturer – VKT (China). Average price - 270 rubles.
Characteristics of the timing belt for the 8-valve VAZ-11189 Lada Vesta engine
VAZ-21129 and VAZ-21179 engines are equipped from the factory with a belt with the article number 8201069699 . The part bears the symbols of Renault, which is the official supplier of Lada parts. Manufacturer: Gates. Average price - 1250 rubles.
Characteristics of the timing belt for 16-valve engines VAZ-21129 and VAZ-21179 Lada Vesta
The most popular analogues for the original timing belt of VAZ-21129 and VAZ-21179 engines:
CT 1179. Manufacturer – CONTITECH (Germany). Average price - 760 rubles. One of the world's five largest suppliers to the automotive sector. The stock of this model is more popular than the original. The reason is that the quality is not inferior to the original, and the price of the part is on average 2.5 times lower.

Provided every 180 thousand km. But experts recommend changing it more often (90-100 thousand km). Much depends on the intensity of use of the car.
One of the main problems when a timing belt breaks is bent valves. Vesta also has this problem. The only exception is the HR16de/h4m engine, on which a chain is installed. To avoid belt rupture and avoid costly valve repairs, you need to check the timing belt at every service.
Engine Lada Vesta It was not by chance that the 1.6-liter engine appeared under the hood of the sedan. This is a fairly reliable power unit, which has managed to take root on other AvtoVAZ models. The simple design of the in-line 4-cylinder 16-valve VAZ-21129 engine has its own characteristics. Durable cast iron cylinder block, aluminum cylinder head, timing belt drive. The 16-valve cylinder head does not have hydraulic compensators; valve clearances are adjusted by selecting special washers of different thicknesses. Motor power Lada Vesta 1.6 is 106 hp. with a torque of 148 Nm.
Electronically controlled multiport fuel injection requires the use of AI-92 gasoline. The Lada Vesta engine complies with Euro-5 environmental standards. The main design feature is the dynamic (passive) supercharging intake system. In the intake manifold, air can move at different speeds thanks to special dampers. This allows you to optimize fuel consumption and increase dynamic characteristics at different engine operating modes.
The Lada Vesta engine also has problems. First of all, it is necessary to note the danger of a broken timing belt. Indeed, in the event of a break in the timing belt on Lada Vesta 1.6 the valve must bend, which meet the piston heads. Therefore, you need to change the Vesta timing belt strictly according to the manufacturer’s regulations.

Engine Lada Vesta It is combined with both a manual 5-speed gearbox and an AMT robotic automatic transmission. Mechanics is a box Renault JH3, which is installed on Renault Logan, and produced in Tolyatti. As for dynamics, a manual transmission is preferable.
Robotic box automatic AMT VAZ-21827 created on the basis of a conventional 5-speed manual transmission. The dynamics with the “robot” on the Lada Vesta are very inexpressive. This state of affairs is due to the settings of the machine. First of all, the developers tried to create an economical unit, and the dynamics were simply sacrificed to this desire. On the other hand, it is better to navigate through traffic jams in large cities of the country using an automatic device. In a traffic jam, speakers are not required at all. Everything about . Fans of the Russian automobile industry have finally waited for the powerful Vesta.
Lada Vesta is a compact small class sedan, located on the border of B and C classes, which began its history in 2015.
The following features of the car can be noted:
- Engine 87–114 horsepower (depending on configuration).
- Cars are equipped with both engines with a timing belt and a chain.
One of the main machine maintenance procedures is replacing the timing belt, which is a consumable item that gradually wears out. If you do not replace it on time, the belt may break sooner or later, which leads to bending of the valves. In this case, you will have to carry out large-scale repairs - install new valves, their guides and pistons. This long and costly process can be avoided if you check the timing mechanism in time and replace it as necessary.
Vesta is available in variations with four different engines, which differ in volume and power:
- VAZ-11189 volume 1.6 l torque 140 N. m and power 64 kW/87 l. With.
- VAZ-21129 volume 1.6 l torque 148 N. m and power 78 kW/106 l. With.
- VAZ-21179 volume 1.8 l torque 170 N. m and power 90 kW/122 l. With.
- HR16DE volume 1.6 l torque 153 N. m and power 114 l. With.
Three variations were created and produced by AvtoVAZ itself, and the fourth model is a product of cooperation between Renault and Nissan, which differs from others in the presence of a mechanical chain instead of a timing belt.
Belt motors
Let's look at three versions of the Lada Vesta engine, equipped with a standard timing belt.
- VAZ-11189
This model is the weakest of all available in the West and is a classic eight-valve. One of the features of the engine is its simplicity. Power is 64 kW/87 hp. pp., which is 27 less than the maximum version. And when it breaks, the valves bend.
- VAZ-21129
The engine is an improved modification of the 21127 engine; it uses 16 valves. If the timing belt breaks on this engine, the valves bend because there are no grooves for them. The recommended timing for replacing the belt is 90 thousand km.
- VAZ-21179
This variation is the leading one among car configurations with a timing belt. The 1.8 liter engine has increased power and 16 valves. It is equipped with a special mechanism for adjustable timing phases, which is a forced rotation of the cam shaft depending on engine operation. But unfortunately, a broken timing belt also leads to bending of the valves.
Chain motor
One of the Vesta engines has a timing chain drive. This is a 1.6 liter Renault-Nissan H4M-HR16 DE engine. It also has an automatic valve timing system. The main problems are chain stretching and tensioner failure. If tension problems do not arise, the chain will never need to be changed.
Timing belt replacement algorithm
Replacement with 21129
Main replacement steps:
- Disconnect the battery.
- Remove the right wheel, fender liner, and engine mudguard.
- Loosen the accessory drive pulley bolt and remove the accessory drive belt.
- Remove the engine cover and right mount.
- Remove the timing cover by unscrewing the five bolts.
- Remove the accessory drive pulley.
- Remove the crankshaft disc and front timing cover.
- Check the alignment of marks A, B, C, D. If necessary, rotate the crankshaft. Check that the mark also matches on the crankshaft pulley.
- Loosen the tension roller and remove the timing belt, starting at the camshaft pulley.
- Replace the tension roller without fully tightening the bolt.
- Install the new timing belt, making sure the timing marks match. Perform all steps in reverse order.
- Tension the belt by turning the pulley clockwise until its cutout aligns with the rectangle.
- Turn the crankshaft 2 turns. If the marks still match, the adjustment has been made correctly.
Replacement with 21179
The timing belt on the 21179 engine should be replaced every 180,000 km, and the pump must also be changed along with the belt. It is believed that the service life of the pump is similar.
It is difficult to replace a motor yourself for several reasons:
- There are no markings on the pulleys on this motor.
- The camshaft must be fixed with a tool, which is also quite difficult to install.
- It is necessary to disassemble a large number of parts to get to the gas distribution mechanism.
To carry out work on replacing the timing belt, you will need to disconnect the lower and upper engine mounts, remove the generator, plastic intake manifold, valve cover and disc.
Since there are no marks on the crankshaft and camshaft, they must be fixed with special tools.
There are slots on the camshaft; their correct location is vertical, parallel to each other.
To secure the crankshaft, you must also use a special tool that will secure the gear through the crankshaft bracket.
Once the crankshaft and camshaft are fixed, you can replace the timing kit in the usual manner.
Replacement with 11189
Replacing the belt on engine 11189 is the easiest of all Lada Vesta engines.
- Disconnect the battery.
- Remove the right front wheel.
- Check that the marks match.
- Remove the timing belt protective cover.
- Remove the alternator belt pulley and loosen the tension roller.
- Remove the timing belt.
- Install the new tension roller without fully tightening it.
- Install the new belt, starting at the camshaft pulley.
- Set the required tension by adjusting the roller.
Which belt to buy
One of the important points when replacing a timing belt is choosing a new one.
On the VAZ-11189 engine, the standard part is numbered 21080100604082, with a standard price of about 300 rubles. It is produced in Poland (Gates company). The most popular analogue would be part VT25009 from China (VKT company), whose price varies around 250–300 rubles.
On the VAZ-21179 and 21129 models, the factory standard will be part number 8201069699, with Renault symbols. Country of manufacture – Poland (Gates), the price is in the range of 1100–1300 rubles. Three options will be proven analogues on vesta without negative reviews:
CONTITECH CT 1179- a German-made part, the quality is not inferior to the original, and the price is 2.5 times cheaper (760 rubles). Is more often used than the original.
Gates 5671 XS – Polish part, price around 1250 rubles. Problems in operation or quality are rare, the parameters are completely similar to the original part.
Bosch 1987949686– version from Germany, price about 800–1000 rubles, a well-known world brand. Mainly used in Renault cars.
Belt replacement interval
What are the dangers of incorrect installation?
Improper replacement of the gas distribution mechanism on a Lada Vesta can lead to damage to the valves in the event of a break. And also, this leads to faster wear of all engine parts associated with the timing system. If you are not confident in your abilities, you should seek the help of a specialist. This will cost approximately 5–6 thousand rubles.
Most likely, every car owner knows what a timing belt device is, but beginners may not fully understand its purpose. So, this belt properly distributes the work of the drive, so to speak, between the gas distribution mechanism, which is abbreviated as the timing belt, and between the special toothed pulleys in the crankshaft. The device is made of high-strength rubber, and on the outside it has a toothed base, which allows you to create movement during operation. The most important question in this matter is: how long does it take to change the belt? The automobile manufacturing company AvtoVAZ, which produces the Lada Vesta, regulates replacement every 200 thousand kilometers. At the same time, it is necessary to take into account the fact that if the belt was manufactured without meeting technical standards, then its service life is reduced significantly. And then the car owner must take care to replace the timing belt in advance, otherwise, due to a malfunction, the belt can easily bend the valves on the power plant.
Can a broken timing belt bend the valves?
Many owners of a car from the Russian Federation Lada Vesta, and other models, are worried that due to the fact that the timing belt was not replaced in a timely manner, this can lead to bending of the valves, and in order to repair them they will have to pay a tidy sum. This is true. Experts say that in car power units that come with a timing belt from the factory, in most new car models, unpleasant valve failures often occur.
The design of the Lada Vesta engine with a power rating of 122 hp will in most cases bend the valves when the belt breaks. Even the fact that at one time, to eliminate this unpleasant situation, grooves were introduced into the piston itself will not help. The depth of these very grooves is not sufficient, and a torn belt easily bends the valves. Avtovaz's creators of the popular domestic car changed the piston system, but did not succeed in this matter. All the same, the valve mechanism came out of order due to the timing belt falling off. And there is only one panacea: timely replacement of the timing belt. And we told you when to change it at the very beginning.
Important!
Domestic Lada Vesta cars bend valves only if they have a belt on them. There are models that AvtoVAZ produces with Nissan engines, in which there is always a chain connection. Consequently, there is no impact on the valves and the chain will never break at one moment, it will gradually fail.
Step-by-step instructions for replacing the timing belt in Vesta (necessary tools)
- We install the Russian Lada Vesta on a lift.
- We remove only one negative terminal on the battery.
- We dismantle the starter and, accordingly, the belt drive of the automobile generator.
- Now lower the lift completely.
- A traverse is carefully installed on the right side of the engine.
- Lift the motor using a hook.
- Using Torx 12 sockets, remove all bolts. A hexagon wrench will be required to unscrew the 8 fasteners, which are located on the protective special casing of the drive (3 on the bottom, 5 on top).
- The following steps when replacing the timing belt entirely depend on what type of unit is in the car. To do this you will need a matching diagram.
- The video material will clearly tell you about all the subtleties that will prevent valve failures.
- After installing a new belt, it is necessary to adjust the tension, and then check the functionality of the entire system.
Let's sum it up
Replacing the timing belt directly in the Lada Vesta model we have designated today is a painstaking and responsible task, but it is quite possible to do it yourself, rather than turning to auto mechanics for help. And some drivers wonder: belt or chain? It cannot be ruled out that the chain, which is a more durable device and does not bend the valves, may one day replace the belt in Vesta.
