Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:
Engine Oil Temperature: 176°F (80°C)

Engine Oil Pressure:

At Idle: 70 kPa (0.7 kgf/cm ² , 10 psi) min.

At 3,000 rpm: 340 kPa (3.5 kgf/cm ² , 50 psi) min.
If the oil pressure is not within specifications, inspect these items:
- Blocking of oil filter.
- Inspect the oil pressure relief valve (see OIL PUMP OVERHAUL ).
