Other mechanical damage such as scratches and burns can easily occur. Piston ring wear often occurs as vehicles age. When the vehicle is at rest, the noise is usually loud. Because it is rare to hit a piston on a new car, as we said before we are strongly recommending a thorough inspection before disassembling the engine.
