Piston is one of the main parts of the engine’s combustion systems. The piston is a moving component that is used to transfer the force from the gas which expands in the cylinders to the crankshaft to turn the wheels.
The most common causes of pistons failures are insufficient cooling, insufficient lubrication of the piston guiding part, thermal fatigue of the piston head surface, failures due to an incorrect combustion process, and mechanical damage.
The best option to prevent costly repair and damage to the other part is to replace the piston with the new one.
