Oil Pressure Test

Check the Oil Pressure

NOTE: Check the oil pressure at the given engine speeds. Carry out the measurement of the oil pressure at a temperature of 80°C.

The oil pressure depends on various factors (engine speed, oil temperature, oil viscosity, degree of contamination of the oil filter).

Oil Pressure Test
1. Disconnect and remove the oil pressure sensor from the engine.
2. Connect the Engine Oil Pressure Gauge to the oil pressure sender oil galley port.
3. Run the engine until normal operating temperature is reached.
4. Run the engine at the specified rpm and record the gauge reading.
5. The oil pressure should be within specification.
6. If the pressure is not within specification, check the following possible sources:
^ insufficient oil
^ oil leakage
^ worn or damaged oil pump
^ oil pump screen cover and tube
^ excessive main bearing clearance
^ excessive connecting rod bearing clearance
