Engine Lubrication System
General Description
Engine Lubrication DescriptionS7RS0B1501001
The oil pump is of a trochoid type, and mounted on the
crankshaft. Oil is drawn up through the oil pump strainer
and passed through the pump to the oil filter.
The filtered oil flows into two paths in cylinder block.
The filtered oil is passed to the passage in heat
exchanger and cylinder block to piston cooling valve of
oil gushed to the lower side of piston. In one path, oil reaches the crankshaft journal bearings.
Oil from the crankshaft journal bearings is supplied to
the connecting rod bearings by means of intersecting
passages drilled in the cran
kshaft, and then injected
from the big end of connecting rod to lubricate piston,
rings and cylinder wall.
In the other path oil goes up to the cylinder head and
lubricates valves and camshafts, etc., after passing
through the internal oil way of camshafts.
An oil relief valve is provided on the oil pump. This valve
starts relieving oil pressure when the pressure exceeds
about 350 kPa (3.5 kg/cm
2, 49.8 psi).

Diagnostic Information and Procedures
Oil Pressure CheckS7RS0B1504001
WARNING!
To avoid danger of being burned, do not
touch exhaust system when it is still hot.

NOTE
Prior to checking oil pressure, check the
following.
• Oil level in oil pan
If oil level is low, add oil up to Full level
mark (hole) (1) on oil level gauge referring
to “Engine Oil and Filter Change in Section
0B”.
• Oil quality If oil is discolored or deteriorated, change
it. For particular oil to be used, refer to
“Engine Oil and Filter Change in Section
0B”.
• Oil leaks If leak is found, repair it.

1) Remove front bumper referring to “Front Bumper and Rear Bumper Components in Section 9K”.
2) Remove engine front cover (1).
3) Disconnect oil pressure switch coupler (1).
4) Remove oil pressure swit ch (2) from cylinder block.
5) Install special tools (oil pressure gauge) to vacated threaded hole of oil pressure switch.

6) Start engine and warm engine up to normal operating temperature.
NOTE
Be sure to shift transaxle gear shift lever in
“Neutral” (shift select lever in “P” range for
A/T vehicle), set parking brake and block
drive wheels.

7) After warming up, raise engine speed to 4,000 r/min. and measure oil pressure.
Oil pressure specification
More than 270 kPa (2.7 kg/cm2, 39.8 psi) at 4,000
r/min. (rpm)
8) After checking oil pressure, stop engine and remove oil pressure gauge and attachment.
9) Before reinstalling oil pressure switch (2), be sure to
wrap its screw threads with sealing tape (1) and
tighten switch to specified torque.
NOTE
If sealing tape edge is bulged out from screw
threads of switch, cut it off.

Tightening torque
Oil pressure switch (a): 13 N·m (1.3 kgf-m, 9.5
lb-ft) 10) Start engine and check oil pressure switch for oil
leakage. If oil leakage is found, repair it.
11) Connect oil pressure switch coupler (1).
