Sealed Power Engine Piston Ring Set P/N:E-938K .25MM
Sealed E-938K .50MM piston ring set for the 1998-2002 Chevrolet Camaro V8 5.7L and other vehicles seals each piston against the cylinder wall and controls oil on that wall. This engine piston ring set is 0.50 mm oversize and covers eight cylinders.
Rising oil use, blue exhaust smoke or low compression can mean worn rings. Before you replace a ring set, rule out other sources of oil and compression loss elsewhere on the engine, since worn rings are only one possible cause.
The set also fits the 2004-2005 Cadillac CTS V8 5.7L and the 1997-2004 Chevrolet Corvette V8 5.7L.
