Valve Stem Seal
Mitsubishi FUSO®

The Valve Stem Seal, also known as the Valve Oil Seal, is a small but important component in the engine of a commercial truck. It is responsible for preventing oil from leaking into the combustion chamber through the valve guides. This is important because if oil leaks into the combustion chamber, it can cause a number of problems, including reduced engine performance, increased emissions, and even engine damage. The Valve Stem Seal is typically made of a high-quality rubber material that is designed to withstand the high temperatures and pressures of the engine. It is installed on the valve stem and creates a tight seal between the valve guide and the valve stem. This ensures that oil stays in the oil passages and does not leak into the combustion chamber. Without a properly functioning Valve Stem Seal, the engine may experience a loss of power, increased fuel consumption, and other issues.
