Oil Recirculation System

External hoses and
der/crankcase passages, and intake manifold pas-
sages are used to recirculate any accumulation 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 intake port areas of the cylinders to circulate
residual oil in the block.

fittings, internal cylin-
External fittings and in-line check valves on each
side of the cylinder block control the movement of
oil from the lower cylinder port to the upper cylin-
der port.
Crankcase / Main Bearing Recirculation
The movement of oil through the main bearings is
controlled by internal passages, external fittings

and hoses, and check valves.
Oil moves from the crankcase areas of the higher
cylinders through grooved passages in the crank-
case to the center and lower main bearings. Addi-
tional oil moves through intake manifold passages
to the crankcase and lower main bearing.
Lower to upper main bearing oil flow:
Oil moves from the lower main bearing cavity to
an external hose with in-line check valve and to
the upper main bearing. Additional oil from the
rear oil manifold is supplied to this oil circuit.
Oil moves from Intake manifold passages to exter-
nal check valve fittings and hoses and to the
upper main bearing.
