Can Engine Cylinder Scoring Be Repaired?

[DeArianna]

Engine cylinder scoring can be repaired if it is only minor by replacing the piston and piston rings, followed by light honing of the cylinder walls. However, if the grooves reach 0.15mm, polishing repairs are not possible. Cylinder scoring refers to deep grooves being formed on the inner walls of the cylinder, causing the piston and piston rings to lose their sealing ability when rubbing against the cylinder walls. This results in reduced cylinder compression pressure and loss of power. An engine is a machine that converts other forms of energy into mechanical energy, including reciprocating piston engines, Stirling engines, steam engines, jet engines, and electric motors. The term engine can refer to both the power-generating device and the entire machine including the power unit.
