Engine Lubrication: Testing and Inspection
OIL PRESSURE
1. Remove the oil pressure gauge unit.
2. Install the oil pressure gauge (49 0187 280) tester.
3. Start the engine and let it warm up to operating temperature.
4. Run the engine at 3,000 rpm and note the gauge reading.
Standard oil pressure: 441-539 kPa (4.5-5.5 kg/cm2, 64-78 psi).
5. If the pressure does not come up to the specified pressure, check for the cause, and repair.
6. Oil pressure drop. Oil pressure becomes low when the engine is cold because the eccentric shaft bypass valve operates.
