1. CHECK THAT SPARK OCCURS
(a) Disconnect the high −tension cords (from the ignition coil)
from the distributor cap.
(b) Hold the end approx. 12.5 mm (0.50 in.) from the body ground.
(c) Check if spark occurs while engine is being cranked.

OIL AND FILTER
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SH Energy−Conserving II multigrade en-
gine oil or ILSAC multigrade engine oil.
Recommended viscosity is as shown in the illustra-
tion, with SAE 5W −30 being the preferred engine oil.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ”L” and ”F” marks on the di\
p-
stick.
If low, check for leakage and add oil up to ”F” mark.
3. REMOVE OIL PRESSURE SWITCH, AND INSTALL OIL
PRESSURE GAUGE
4. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
5. CHECK OIL PRESSURE Oil pressure:
At idle
29 kPa (0.3 kgf/cm
2, 4.3 psi) or more
At 3,000 rpm
245 − 490 kPa (2.5 − 5.0 kgf/cm
2, 36 − 71 psi)
6. REMOVE OIL PRESSURE GAUGE AND REINSTALL OIL PRESSURE SWITCH
(a) Remove the oil pressure gauge.
(b) Apply adhesive to 2 or 3 threads of the oil pressure switch.
Adhesive:
Part No. 08833 −00080, THREE BOND 1344,
