Sealed Power Engine Piston Ring Set P/N:E-261K 30
Sealed E-261K piston ring set for the 1967-1970 Ford Mustang V8 7.0L and other vehicles seals each piston against its cylinder wall. Also called an engine piston ring set, it covers all eight cylinders of the engine, and it meets or exceeds OEM specifications.
Rising oil use or weak compression can be signs of worn piston rings. Before you replace the rings, rule out other causes such as worn valve seals or a leaking head gasket, since a shop can test for those.
The 1967-1970 Ford Mustang V8 7.0L, the 1969-1970 Mercury Marauder V8 7.0L and the 1966-1970 Ford Country Sedan V8 7.0L take this set, as do many other Ford and Mercury models, and one set covers the eight cylinders of each. The Sealed Power Vintage line covers applications over 35 years old. If your Ford or Mercury is not named here, look it up in the "Vehicles it fits" section.
