Supertech Nissan 6mm Viton Exhaust Valve Stem Seal - Set of 8

Supertech is known for making well-built internal engine components. This set of eight 6mm Viton exhaust valve stem seals is a prime example, designed to keep oil from entering your exhaust ports. When these seals wear out, you might notice blue smoke on startup or when decelerating, and oil consumption can increase. Replacing them is a common part of rebuilding an engine's top end or addressing oil burning issues.

These seals use Viton, a material known for its excellent resistance to heat and oil, making it a solid choice for exhaust valve applications where temperatures can get quite high. The 6mm size is specific to certain Nissan engines, ensuring a proper fit when you're working on those applications. Installing these typically involves removing the cylinder head and using a valve spring compressor tool to access the valve seals.
