Failure Symptoms

Initial signs of failure may include increased engine blow-by or a subtle drop in compression. If left unaddressed, these symptoms can progress to noticeable power loss and increased oil consumption. The ultimate consequence is potential engine damage, including scoring of the cylinder walls or piston seizure.

Installation Tip

Ensure the cylinder bore is clean and properly lubricated before installing the piston assembly to prevent initial scoring. Avoid rotating the crankshaft forcefully until the piston rings have seated properly.

Service Note

When replacing the piston crown and skirt, it is crucial to inspect and replace the piston rings, cylinder liners, and connecting rod bearings.
