Crankcase
Inspection and Service
Check all gasket surfaces to make sure they are free of
gasket fragments and deep scratches or nicks.
Check cylinder wall for scoring. In severe cases,
unburned fuel can wash necessary lubricating oil off
piston and cylinder wall. Piston rings make metal to
metal contact with wall, causing scuffi ng and scoring.
Scoring of cylinder wall can also be caused by localized
hot spots from blocked cooling fi ns or from inadequate or
contaminated lubrication.
If cylinder bore is scored, worn, tapered, or out-of-
round, use an inside micrometer or telescoping gauge
to determine amount of wear (refer to Specifi cations).
If wear exceeds published limits, a short block or
replacement engine will need to be considered.
