Engine Lubrication: Testing and Inspection

Engine Oil Pressure Check
1. Check for dirt, gasoline or water in the engine oil.
a. Check the viscosity of the oil.
b. Change the oil if the viscosity is outside the specified standard.

2. Check the engine oil level.
The level should fall somewhere between the "ADD" and the "FULL" marks on the oil level dipstick.
If the oil level does not reach the "ADD" mark on the oil level dipstick, engine oil must be added.
3. Remove the oil pressure unit.
4. Install an oil pressure gauge.
5. Start the engine and allow the engine to reach normal operating temperature (About 80° C).
6. Measure the oil pressure.
Oil pressure should be:
150 kPa (21.8 psi) at idle speed.
7. Stop the engine.
8. Remove the oil pressure gauge.
9. Install the oil pressure unit.
10. Start the engine and check for leaks.
