Sealed Power Engine Piston Ring Set P/N:E-991K
Sealed Power E-156X piston ring set for the 1954-1964 Ford F-250 6-cylinder 3.6L and other vehicles seals combustion pressure and controls oil on the cylinder wall. This engine piston ring set covers six cylinders and meets or exceeds OEM specifications.
Rising oil use, blue exhaust smoke or weak compression can mean worn rings. Worn cylinders or valve guide seals can produce similar symptoms, so find the cause first: with the engine apart and cool, measure the cylinder bore for wear and taper, and leave compression or leak-down testing to a shop.
This Sealed Power piston ring set also fits the 1964 Ford Custom 6-cylinder 3.6L, the 1959-1964 Ford Galaxie 6-cylinder 3.6L and the 1960 Galaxie 6-cylinder 3.7L. The 1964 Ford Custom 6-cylinder 3.6L takes one set. If your truck or car is not named here, open the "Vehicles it fits" section to check your exact model and engine.
