5 small driver mistakes that lead to serious engine repairs

During the operation and maintenance of the car, the owner, as a rule, does not think about how to carry out simple repairs and maintenance of his car. As a result, there are serious problems with the motor, which were easy to avoid. The AvtoVzglyad portal tells about the simplest and most dangerous mistakes that lead to expensive repairs.

Clogged fuel injectors are one of the most common problems that occur in cars whose owners do not pay due attention to them. The fact is that over time, the fuel system of absolutely all engines becomes clogged with dirt, even if the driver regularly fills in high-quality gasoline. If the injectors are not cleaned, they begin to pour instead of spraying fuel, which leads to increased fuel consumption and detonation. And detonation can quickly finish off the engine.

Serious problems can also be obtained after service errors. For example, the air filter is installed so that its edge is broken or loosely pressed against the body. Thus, particles of dirt and sand get into the engine. Since sand is an excellent abrasive, it begins to scratch the walls of the cylinders, which leads to the appearance of scuffs on their walls. And the bullies slowly bring the engine closer to the capital.

The same thing happens with the cabin filter. If it is installed skewed, dust and dirt will settle on the air conditioner evaporator. Over time, this will lead to the fact that bacteria will begin to multiply on the surface. Such air, entering the cabin, will cause colds or allergies in the driver.

Scuffing in the cylinders can also appear with a simple replacement of spark plugs. If you do not clean the candle wells before unscrewing them, then all the dirt will get inside, which will eventually make itself felt.

A clogged EGR valve can also cause serious trouble. Due to the fact that it periodically sticks, the engine can work uncertainly at idle, or even completely stall on the road. This will lead to an accident, especially if a novice driver is driving, because he will definitely be afraid that the engine has suddenly stopped.
