DESCRIPTION
A valve stem guide is a component of an internal combustion engine that ensures the proper alignment and stability of the valve stem within the cylinder head. The part number 66890 refers to a specific valve stem guide used in certain truck engines. Made from durable materials such as bronze or steel, the valve stem guide is fitted into the cylinder head and serves as a guide for the valve stem, preventing it from wobbling or vibrating excessively during engine operation. Additionally, it helps to dissipate heat generated by the combustion process away from the valve stem, preventing premature wear and damage to both components. Overall, a properly functioning valve stem guide is essential for maintaining engine performance and longevity in heavy-duty trucks.
