On which VAZ engine does not bend the valve: characteristics and history

The automotive industry knows thousands of engine options that are not very pleasant to drive. In particular, on such power units, when the timing belt breaks, the valves are bent, which meet the pistons in a chaotic inertial stroke. Bending valves will have to be treated by replacing them, as well as a bulkhead of the entire upper part of the engine. This will cost the owner of even an inexpensive domestic car more than 15,000 rubles. Therefore, if this is possible, 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 car engines. 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 with various problems.

AvtoVAZ generally designed quite interesting power units. Yes, most of them had not so much 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 and negative situations. In many units, they didn’t even change the oil, filling once for 30-40 thousand with cheap mineral water, which they could get in the days of the Soviet Union. So it’s not worth scolding the engines of the first VAZ models, up to the VAZ 2108 and 2109. It turns out that it was the best time of the domestic auto industry, which showed maximum potential and minimum problems in use.

VAZ engines from 2101 to 2106

Often, in old cars, VAZ used the simplest technologies. The developments of the 70s of the last century actually served until recently, because the latest version of 2106 was discontinued just a few years ago. It is very interesting that engines were installed on 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, went 50-60 thousand kilometers (or more than 200 in the case of a chain);
• 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 of the world.

At the time of development of each of the VAZ vehicles in the 2101 - 2106 range, 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 never bend valves, and other problems are not terrible for the power unit. 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 that serve quite adequately and do not fail for years. You can drive about 200-250 thousand kilometers on one chain, then replace it simply because the conscience of the motorist began to remind you of maintenance.

It is important to remember that if the chain began to produce 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 for 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 hardy cars, they were produced up to our time, they were assembled in Ukraine for several years, but they have completely lost their appearance and technology relevance. Today you can buy on the secondary market an excellent version of the "Nine" of a completely fresh year of manufacture in perfect condition. The engine in this car has the following features:

• there were in the history of the model a power unit of 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 a broken timing belt, the valves in the power unit did not bend;
• the car had quite adequate engine reliability - this unit was the last to break in the car;
• all presented competitors at one time were carried by 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. The buyers of such cars have become real lucky ones in the eyes of acquaintances and friends, exactly the same as today's buyers of the latest Mercedes models. 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 new products of domestic development. Today, the "Ten" is considered quite adequate transport with certain problems in the assembly. On these models, the engines were installed differently and they had different characteristics:

• The 1.5-liter 8-valve simple power unit did not bend the valves, but showed only 72 horsepower;
• 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 valve design should have spared, but did not;
• also, you will not wait for a cheap repair after a broken timing belt on the most powerful 1.6-liter 16-valve VAZ 2110 engine.

The entire family of "Tenth" models was quite high-quality and reliable, but the further the plant tried to keep up with power, modernity and relevance, the more trouble the car got. The most enduring 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 feedback from car owners.

The modern era of VAZ engines - the main problems

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

• Priora's base engine is a 98-horsepower power unit, the only one that spares 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;
• The 1.6-liter engine with 8 valves of French origin does not bend the valve on the Largus;
• 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 another important representative of the company. The Lada 4x4 car offers a good 1.7-liter power unit with 8 valves, which has protection against bending these same valves. The unit, though not too powerful, but quite reliable. We offer you to see a short review 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 Grant or Kalina often turn out to be the only possible purchase for a Russian family. The sharp increase in prices for other new cars responds with the need to buy domestic developments. It should be noted that AvtoVAZ is doing tremendous 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 Priore. However, everything here is arranged in such a way that you may not be lucky, so 16 valves will have to be changed after a belt break. 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.
