LUBRICATION
DESCRIPTION
The lubrication system is a full flow filtration pres-
sure feed type. The oil pump is mounted in the tim-
ing chain cover and is driven by the crankshaft
OPERATION
Oil from the oil pan is pumped by a internal gear
type oil pump directly coupled to the crankshaft. The
pressure is regulated by a relief valve located in the
timing chain cover. The oil is pumped through an oil
filter and feeds a main oil gallery. This oil gallery
feeds oil under pressure to the main and rod bear-
ings, camshaft bearings. Passages in the cylinder
block feed oil to the hydraulic lifters and rocker shaft
brackets which feeds the rocker arm pivots (Fig. 95).
DIAGNOSIS AND TESTING - ENGINE OIL
PRESSURE
(1) Disconnect and remove oil pressure switch
(Refer to 9 - ENGINE/LUBRICATION/OIL PRES-
SURE SENSOR/SWITCH - REMOVAL).
(2) Install Special Tools C-3292 Gauge with 8406
Adaptor. For Special Tool identification, (Refer to 9 -
ENGINE - SPECIAL TOOLS).
(3) Start engine and record oil pressure. Refer to
Oil Pressure in Engine Specifications for the correct
