What to check before replacing a WP9 piston
Pistons in WP9 engines fail in predictable ways. Before ordering, check the following: crown erosion from injector spray pattern faults, ring groove wear on the top groove, skirt scuffing from overheating or poor lubrication, and pin bore clearance. If the bore is scored, the liner must be replaced together with the piston — fitting a new piston into a worn liner causes piston slap and rapid ring failure.
Our WP9 pistons are supplied complete with pin and circlips where the original design requires them. We match ring grooves to the OEM configuration so your existing ring set can be reused if it is still within tolerance.
