INSPECTION
Check valves for burning. Replace if necessary.
Check separator plate for scratches or damage. Replace if
necessary. Scratches or score marks can cause oil to
by-pass correct oil passages and result in system malfunc-
tion.
Check oil passages in upper and lower valve bodies for
varnish deposits, scratches or other damage that would
impair valve movement. Check threaded holes and related
bolts and screws for stripped threads; replace as needed.
Check valve springs for damage. Measure their free length.
If the free length is out of specification, replace valve
springs.
