About this part

Product Details

If you're rebuilding the top end of your BMW N54, N55, S55, B48, B38, or B58 engine, replacing the valve stem seals is a critical step. These seals sit on the valve stem and keep oil from entering the combustion chamber when the valve is closed. Worn-out seals are a common cause of blue smoke on startup and increased oil consumption, especially in high-mileage or performance-tuned engines.

This set from Supertech uses Viton, a high-performance fluoroelastomer known for its excellent resistance to heat and oil. The integral design means the seal is a single piece, making installation straightforward compared to separate seals and retainers. Each seal is well-built to maintain its sealing properties under the demanding conditions found in these BMW engines, helping to restore proper valve sealing and reduce oil burning.
