About this part

Product Details

This listing is for a single Supertech valve stem seal, designed for Yamaha engines with 4.5mm valve stems. These seals are crucial for preventing oil from entering the combustion chamber through the valve guides, which helps maintain engine performance and reduce oil consumption.

Made from a durable material, this seal is built to withstand the heat and pressure found in the engine's valvetrain. Proper installation of valve stem seals is a common step when rebuilding an engine or addressing issues like blue smoke on startup or during deceleration. Ensuring each seal is correctly seated is important for its function.
