Supertech Ford Duratec 5.5mm Viton Integral Valve Stem Seal w/Spring Seat - Set of 8

This set includes eight Supertech integral valve stem seals with spring seats, specifically designed for Ford Duratec engines. These seals are crucial for preventing oil from leaking down the valve guides into the combustion chamber, which can cause blue smoke on startup and increased oil consumption.

Made from Viton, these seals offer good resistance to heat and oil, helping them last longer in demanding engine conditions. The integral spring seat design ensures a secure fit and proper sealing action. Replacing worn valve stem seals is a common part of engine rebuilding or repair to restore proper engine operation and reduce emissions.
