Oil Recirculation System

External hoses and
der/crankcase passages, 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.
Cylinder Recirculation
Internal powerhead oil drain passages connect
the lowest point of the intake port area of the cylin-
der block to external check valves. External hoses
connect these check valves to a hose fitting
pressed into the top of the intake manifold / throt-
tle body. Intake manifold vacuum draws any accu-
mulation of oil from the intake port area of the

cylinders into the incoming air stream in front of
