Federal Mogul SS71146 Valve Stem Seal - Set

The Federal Mogul SS71146 Valve Stem Seal Set delivers professional-grade engine sealing for Cadillac and Oldsmobile V8 applications. Valve stem seals allow a controlled amount of oil to lubricate the valve stem as it moves in the valve guide, and the Fel-Pro Engineering team reviews the OE designs for each valve stem seal to determine the best solution for the application.

Key Features:

• Built to meet or exceed all original equipment specifications and is validated for fit, form, and function
• Application-specific design using either deflector (umbrella) seals or positive seals with quality materials based on the specific application
• Installation tool included (where applicable) - a thin plastic sleeve which is placed over the tip of each valve stem during installation to protect the inner lip of the seal from damage by the lock grooves
• Engineered specifically for the aftermarket repair environment

Excessive oil consumption from worn valve stem seals can lead to carbon build-up on valves, rough idle, detonation issues, increased emissions, and catalytic converter degradation. With repeated exposure to heat and oil, valve stem seals can fail, becoming hard or worn and unable to properly control oil flow. This Fel-Pro valve stem seal set provides the reliable replacement you need to restore proper engine function and prevent costly damage.
