Sealed Power Engine Piston Ring Set P/N:E-251K
Sealed Power E-251K 60 piston ring set for the 1975-1996 Ford F-150 5.0L / 5.8L / 6.6L and other vehicles supplies the top, second and oil rings for eight cylinders in a 0.060 in oversize.
Blue exhaust smoke, oil use between top-ups or low compression can mean worn rings. These signs alone do not prove the rings are the problem, since leaking valve stem seals can also burn oil. One set covers every cylinder in the engine.
The set also fits the 1988-1995 Chevrolet C1500 5.7L and the 1988-1995 Chevrolet K1500 5.7L. If your vehicle is not named here, check its year and engine on the Buyer's Guide tab.
