MK667085
Valve Spring Retainer
Mitsubishi FUSO®

A valve spring retainer is a small but critical component of an engine's valvetrain system. It is typically made of metal and is designed to hold the valve springs in place, ensuring that they remain securely attached to the valve stem. The MK667085 valve spring retainer is a specific part used in some truck engines. It is important for the proper function of the engine, as it helps to maintain the correct amount of pressure on the valve springs, which in turn helps to ensure that the valves open and close at the appropriate times. Without a properly functioning valve spring retainer, an engine's valvetrain can become damaged or fail altogether, leading to significant performance issues and potential engine damage.
