DESCRIPTION
A Valve Insert, also known as a valve seat insert, is a small part that fits inside the cylinder head of an internal combustion engine. The Valve Insert provides a surface for the intake and exhaust valves to seat against when they are closed. This helps to create an effective seal between the valve and the cylinder head, which is essential for proper engine performance. The Valve Insert is typically made from materials such as hardened steel or bronze, and it may need to be replaced periodically due to wear or damage. Proper installation of the Valve Insert is crucial for maintaining engine efficiency and preventing leaks or other issues. Part Number 4374020 specifically refers to a particular type of Valve Insert used in certain truck models.
