DESCRIPTION
A valve insert, also known as a valve seat insert, is a component of an engine's cylinder head that provides a durable and heat-resistant surface for the intake and exhaust valves to seat against. The valve insert is typically made of a hard metal alloy and is press-fit into the cylinder head. Over time, the valve inserts can wear or become damaged due to high temperatures and combustion pressures. When this occurs, it may be necessary to replace the valve inserts to ensure proper sealing between the valves and cylinder head. The part number for this specific valve insert is 3943449.
