VLVOS021"Another great Inlet/Exhuast Valve"
A valve stem oil seal is a small but crucial component in a motorcycle engine that prevents oil from leaking into the combustion chamber through the valve stem. It is positioned around the valve stem, between the valve guide and the spring retainer. The seal ensures that engine oil remains in the correct area, avoiding excessive oil consumption and preventing smoke from the exhaust. Made from durable materials like rubber or silicone, it helps maintain engine performance and longevity by keeping the oil where it should be and reducing emissions.
