Sealed Power Engine Piston Ring Set P/N:E-243K 40
Sealed E-243K 60 piston ring set for the 1970-1976 Chevrolet Impala V8 6.6L and other vehicles seals each piston against its cylinder wall. It also helps control oil on the cylinder wall, and the rings are made to OEM specifications or better.
A worn engine piston ring set can show up as blue exhaust smoke, rising oil use or lost compression. Before you replace the rings, rule out other sources of oil use, such as valve stem seals or an external oil leak, since those can look much the same.
The 1970-1976 Chevrolet Impala V8 6.6L, the 1966 Dodge Charger V8 5.9L and the 1961-1964 Chrysler Town & Country V8 5.9L all fit this ring set, and so do more vehicles. If your car isn’t one of these, look it up in the “Vehicles it fits” section.

This part cross-references / interchanges with the following part numbers:
Does the Sealed E-243K 60 ring set fit the 1966 Dodge Charger V8 5.9L?
Yes. Sealed E-243K 60 is listed for the 1966 Dodge Charger V8 5.9L, and the application takes one set. Other fits are in the “Vehicles it fits” section.
How far oversize is this piston ring set?
It is 0.060 inch oversize, meant for a cylinder bored out to that size.
What are the top rings made of on the Sealed E-243K 60 set?
The top rings on Sealed E-243K 60 are steel with moly. Their faces carry a Plasma-Moly coating, which decreases friction and resists scuffing.
Can worn piston rings cause blue smoke from the exhaust?
Yes, they can. Worn rings can let oil reach the combustion chamber and burn, and lower compression or higher oil use may go with it. A shop can run a compression test.
Does this ring set cover all eight cylinders of a V8?
Yes. The set is made for 8 cylinders, and one set is the quantity per engine.
