Valve Seat: Testing and Inspection

Check the valve seat for evidence of overheating and improper contact with the valve face. Replace the seat if necessary.





Before reconditioning the seat, check the valve guide for wear. If the valve guide is worn, replace it, then recondition the seat. Recondition the valve seat with a valve seat grinder or cutter. The valve seat contact width should be within specifications and centered on the valve face.
