Federal Mogul SS71245 Valve Stem Seal Set

The Fel-Pro SS71245 Valve Stem Seal Set provides a precision-engineered solution for controlling oil flow to valve stems and preventing excessive oil consumption. Fel-Pro engineers review OE designs for each valve stem seal application to ensure reliable sealing on even the most troublesome applications.

Key Features:

• Application-specific materials designed for your vehicle repair, using either deflector (umbrella) seals or positive seals
• Validated and approved by Fel-Pro engineers through rigorous research, development and testing
• Installation tool included (where applicable) - a thin plastic sleeve that protects the inner lip of the seal from damage by the lock grooves during installation
• Premium Viton material offers excellent resistance to both heat (up to 450°F) and abrasion
• 100% vehicle sealing with application-specific materials for performance and durability

Function and Importance:

Valve stem seals allow a controlled amount of oil to lubricate the valve stem as it moves in the valve guide, and this amount must be precisely controlled. Too little oil causes stem and guide wear, while too much oil causes carbon buildup leading to valve seat damage, decreased volumetric efficiency, increased emissions, catalytic converter degradation, and excessive oil consumption.

Signs You Need New Valve Stem Seals:

• Blue-white smoke from the tailpipe, especially at cold startup or acceleration
• Excessive oil consumption
• Degradation of the catalytic converter resulting in a Check Engine light
• Excessive carbon buildup on valves resulting in rough running

With repeated exposure to heat and oil, valve stem seals can fail, becoming hard or worn and unable to properly control the amount of oil going down the valve guide. This Fel-Pro set ensures proper oil metering and long-lasting engine performance.
