Federal Mogul SS73055 Valve Stem Seal Set

The Federal Mogul SS73055 Valve Stem Seal Set is engineered to provide reliable sealing performance for critical engine applications. Fel-Pro's engineering team reviews OE designs to determine the best sealing solution for each specific application.

Key Features:

• Application-specific design using deflector (umbrella) seals, O-ring style, or positive seals based on vehicle requirements
• Premium quality materials selected for the specific application to ensure optimal performance and durability
• Validated for fit, form, and function through rigorous engineering review and testing
• Includes installation tool (where applicable) - a protective plastic sleeve that prevents damage to the seal's inner lip during installation by covering valve stem lock grooves
• Meets or exceeds original equipment specifications

Valve stem seals control the precise amount of oil needed to lubricate valve stems as they move within valve guides. Proper oil metering is critical - too little causes wear, while too much leads to carbon buildup, rough idle, increased emissions, and excessive oil consumption.

Over time, repeated exposure to heat and oil causes valve stem seals to harden or wear, preventing proper oil control. Common symptoms of failed seals include blue-white smoke from the tailpipe (especially at cold startup), excessive oil consumption, and rough engine performance.
