How to avoid bending the valves when the timing belt breaks

A broken timing belt is fraught with serious engine repairs, and this scares most motorists. Sometimes you can’t get away from trouble, because the belt can be damaged, and for various reasons. How to avoid serious repairs, the AvtoVzglyad portal will tell.

As a rule, the timing belt is recommended to be changed after 60 km, but problems can arise much earlier. For example, due to a jammed pump, and this will “finish off” the engine. Such a nuisance can overtake the owners of "our brands" already at 000 km due to the fact that the water pump is not of very good quality.

In most cases, a broken belt causes the valves to collide with the pistons. As a result of the impact, the valves are bent, and the engine is in danger of a major overhaul, which deals a serious blow to the budget.

Experienced drivers, faced with a broken belt, found a way out of the situation. They turn to servicemen who carry out the so-called piston pricing. Masters make special grooves on the surface of the piston, which save them from impact in the event that the timing belt breaks again.

Another option is to put pistons that already have such grooves. After all, manufacturers are aware of the problem and are also modifying their products.

Let's not forget about the old-fashioned method, which is great for atmospheric engines. Several gaskets are placed under the cylinder head. For example, two standard ones, and between them - steel. This solution reduces the risk of collision between valves and pistons to almost zero, because the gap between them increases.

Previously, such “sandwiches” were often sold at car markets, although manufacturers did not approve of this, because there are plenty of minuses here. The fact is that over time, the gaskets can “sit down”, and the cylinder head will have to be stretched, otherwise the gaskets may burn out. It is worth considering the fact that the increased clearance between the valves and pistons leads to a decrease in engine power. But you certainly can not be afraid of a broken timing belt.
