Valve Stem Seal
Mitsubishi FUSO®

The Valve Stem Seal, also known as the Valve Seal, is a small but important part of a commercial truck's engine. Its primary function is to prevent 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 such as reduced engine performance, increased emissions, and even engine damage. The Valve Stem Seal is made of high-quality materials that are designed to withstand the high temperatures and pressures of the engine. It is a vital part of the engine's overall performance and should be checked regularly to ensure that it is functioning properly. In addition to preventing oil leaks, the Valve Stem Seal also helps to maintain proper oil pressure in the engine. This is important because if the oil pressure is too low, it can cause engine damage and reduce performance. The Valve Stem Seal works by creating a tight seal around the valve stem, which helps to maintain the proper oil pressure in the engine. Overall, the Valve Stem Seal is a small but important part of a commercial truck's engine that plays a critical role in maintaining engine performance and preventing damage.
