Engine Piston – Volvo (9487331)

Engine Piston is a reciprocating component that seals the combustion chamber. Clearance and surface finish decide whether it seals correctly, so the bore has to be measured before a replacement is chosen.

Replace the Engine Piston when a leak-down test shows air escaping past the rings, when the skirt is scuffed, or when ring lands are cracked. Check the ring end gap in the bore it will run in.
