OILING SYSTEM
COMPONENTS
On 3.3 L models, one oil distribution hose is
routed to a tee fitting at the top of the block, above
#2 cylinder.
Oil Recirculation System
External hoses and fittings, internal cylin-
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
the top reed valve.
Check valves pressed into the crankcase below
#4 and #6 reed valve assemblies connect to
