Wear, Scratches, and Burrs Inspection

CAUTION: Small scratches, scores or scuffs on the valve stem will damage and wear out the valve stem seal. Always lubricate the valve guide and valve stem before installing a new valve stem seal. If a valve stem seal is removed after installation, it must be discarded.





^ Using a ball gauge or SA91102NE (or equivalent), measure the inside diameter of the valve guide bore.
