Oil Recirculation System

External hoses and fittings, and intake manifold
passages are used to recirculate any accumula-
tion of oil from various locations in the powerhead.
The movement of oil is controlled by check valves.
Crankcase / Main Bearing Recirculation
The movement of oil through the main bearings is
controlled by internal passages, external fittings
and hoses, and check valves.
Lower to upper main bearing oil flow:
•
Lower main bearing cavity to internal crankcase
passage to external fitting, external hoses with
in-line check valve to external fitting at upper
main bearing, and into upper main bearing
through internal crankcase passage.
