INSERT - VALVE SEAT EX (CAT CT0679565)

A worn valve seat insert can cause poor sealing and reduced compression in the cylinder head. This aftermarket replacement part references CAT as the OE maker and carries the cross-reference part number CT0679565. The insert is a valve seat component that provides a sealing surface for the valve head during operation. A common failure consequence of a degraded valve seat is loss of compression, leading to hard starting or misfiring. In a typical usage context, this part is replaced during a cylinder head overhaul to restore proper valve closure. The item ships at approximately 0.082 pounds.
