DESCRIPTION
A valve insert, also known as a valve seat insert, is a component in an internal combustion engine that provides a sealing surface for the engine's valves. The valve insert is typically made of hardened steel or other wear-resistant material and is pressed into the cylinder head where it sits in a machined pocket. The valve insert serves to protect the softer metal of the cylinder head from damage by the reciprocating motion of the valves while also providing an air-tight seal to prevent combustion gases from escaping past the valves. Part number 3686785 refers to a specific type of valve insert used in certain truck engines.
