14.13 INSPECTION OF VALVE
The valve stems must be free from scratches or scuff marks, and the valve faces must be free from
ridges or cracks. Some pitting of the valve face is normal, and is acceptable as long as no leak
paths are evident. If leak paths exist, re-face the valves or install new valves. If the valve heads
are warped or the valve stem is bent, replace the valves. See Figures 14-10 and 14-11.
