Sealed Power Engine Piston Ring Set P/N:E-233K 20
Sealed Power E-233K piston ring set for the 1990 Chevrolet C1500 V8 7.4L and other vehicles seals the pistons against the cylinder walls. This engine piston ring set covers eight cylinders, and each Sealed Power piston ring in it is made to exacting tolerances.
Worn rings can show up as oil consumption, blue exhaust smoke or low compression. Before you replace the rings, rule out other sources of oil use, such as valve seals or leaking gaskets, because they can look the same; a shop can run a compression test. The 1990 Chevrolet C1500 V8 7.4L takes one set, which covers all eight cylinders.
This set is listed for a wide range of Chevrolet, Dodge and Plymouth models, including the 1966-1969 Chevrolet Impala V8 7.0L, the 1970-1976 Impala V8 7.4L and the 1966-1971 Dodge Charger V8 6.3L or 7.0L. Open the "Vehicles it fits" section to check your exact model and engine. The rings meet or exceed OEM specifications.
