CP Piston Oil Ring for 78-87 Buick Grand National

This CP Piston oil ring set is built with a specific tensioning design to ensure it seals properly against the cylinder wall. It's designed to work with CP Pistons' 3.8L Turbo V6 pistons, commonly found in the 1978-1987 Buick Grand National. Proper oil control is crucial for engine health, preventing excess oil from entering the combustion chamber, which can lead to smoking, fouled spark plugs, and reduced performance.

When you're rebuilding or refreshing the engine in your Grand National, using a well-built oil ring set like this one from CP Pistons helps ensure your engine runs cleanly and efficiently. These rings are made to precise specifications to maintain good contact with the cylinder walls, even under the stress of boosted applications. It's a small but vital part of the overall sealing package for your engine.
