About this part

Product Details

This is a single Supertech 6.6mm Viton exhaust valve stem seal, standard size. It's a small but crucial part for keeping your engine running right. Its main job is to seal the valve stem where it passes through the cylinder head, preventing oil from getting into the exhaust port and burning off. When these seals wear out, you'll often notice blue smoke coming from your tailpipe, especially after the engine has been sitting for a bit and then you accelerate.

Made from Viton, this seal is built to handle the high temperatures found around the exhaust valve. Viton is a well-known material for its resistance to heat and oil, which is exactly what you need in this location. Because it's a direct replacement for the original part, it fits right onto the valve stem and into the cylinder head without any modifications, making the job straightforward if you're already rebuilding your cylinder head or replacing valve springs.
