Valve Inspection

or brush.
2. Check valve face for runout, pitting, and burnt spots.
To check for bent valve stems, mount valve in a drill
or use “V” blocks and a dial indicator.
3. Check the end of the valve stem for flaring, pitting,
wear or damage.
4. Inspect split keeper groove for wear or flaring in the
keeper seat area.
NOTE: The valves can be re-faced or end
ground, if necessary. They must be replaced if
extensively worn, burnt, bent or damaged.
