LUBRICATION
DESCRIPTION
The oil lubrication system is a full-flow filtration, pressure feed type. The oil pump body is mounted to the engine
block. The pump inner rotor is driven by the crankshaft. A windage tray, increases power by minimizing oil windage
at high engine RPM. For increased oil cooling, an oil pan mounted, oil-to-coolant oil cooler is used.

OPERATION
Engine oil stored in the oil pan (5) is drawn in and discharged by a gear rotor type oil pump (2, 3). The oil pump
is directly coupled to the crankshaft (1). Oil pressure is regulated by a relief valve (4). The oil is fed through an oil
filter and to the crankshaft journals from the oil gallery (8) in the cylinder block. This gallery also feeds oil under
pressure to the cylinder heads. Oil flows through each cylinder heads oil passage to the rocker shafts (10, 16). Oil
then feeds the camshaft journals (12), rocker arms, and hydraulic lash adjusters.

DIAGNOSIS AND TESTING
CHECKING ENGINE OIL PRESSURE
Check oil pressure using a gauge at oil pressure
switch (1) location.
1. Remove the oil pressure switch (1) (Refer to 9 -
ENGINE/LUBRICATION/OIL
PRESSURE
SEN-
SOR/SWITCH - REMOVAL).
2. Install oil pressure test gauge, C-3292 with Adapter
8406. For Special Tool identification, (Refer to 9 -
ENGINE - SPECIAL TOOLS).
CAUTION: If oil pressure is 0 at idle, Do Not Run
engine at 3000 RPM.
3. Warm engine to normal operating temperature.
4. Monitor gauge readings at idle and 3000 rpm. For
specifications
(Refer
to
