LIQUID GASKET APPLICATION PROCEDURE
a. Before applying liquid gasket, use a scraper to remove alltraces of old liquid gasket from mating surface.
b. Apply a continuous bead of liquid gasket to mating sur- faces.
(Use Genuine Liquid Gasket or equivalent.)
I Be sure liquid gasket is 3.5 to 4.5 mm (0.138 to 0.177
in) wide (for oil pan).
I Be sure liquid gasket is 2.0 to 3.0 mm (0.079 to 0.118
in) wide (in areas except oil pan).
c. Apply liquid gasket to inner sealing surface around hole perimeter area.
(Assembly should be done within 5 minutes after coating.)
d. Wait at least 30 minutes before refilling engine oil and engine coolant.

Oil Pressure Check
WARNING:
IBe careful not to burn yourself, as the engine and oil may
be hot.
I Oil pressure check should be done in ªNeutralº gear posi-
tion.
1. Check oil level.
2. Remove oil pressure switch.
3. Install pressure gauge.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.
Engine rpm Approximate discharge pressure
kPa (bar, kg/cm2, psi)
Idle speed More than 78 (0.78, 0.8, 11) 3,000 294 - 392 (2.94 - 3.92, 3.0 - 4.0, 43 - 57)
If difference is extreme, check oil passage and oil pump for oil
leaks.
6. Install oil pressure switch.
Use proper liquid sealant. Oil pressure switch:
:10-13N ×m (1.0 - 1.3 kg-m, 87 - 113 in-lb)

Oil Pump
OIL PUMP INSPECTION
1. Inspect pump body, gears and drive shaft for wear and dam-age.
2. Using a feeler gauge and fuse wire, check the following clear- ances.Gear side clearance: Less than 0.13 mm (0.0051 in)
Gear backlash: Less than 0.43 mm (0.0169 in)
3. Measure inside diameter ªAº of bushing. A: 13.012 - 13.098 mm (0.5123 - 0.5157 in)

4. Measure outside diameter ªBº of drive gear shaft.B: 12.974 - 12.992 mm (0.5108 - 0.5115 in)
5. Calculate oil pump bushing clearance. Oil pump bushing clearance (A þ B):Less than 0.15 mm (0.0059 in)
If it exceeds the limit replace oil pump bushing or entire oil
pump assembly.
