4. Examine for any sign of damage
or score marks on separate plate. If

oil passages causing many types of
abnormalities in the system.
5. Check oil passages in valve body
for sign of damage and other conditions
which might interfere with proper
valve operation.
6. Check bolts for stripped threads.
Replace as required.
