Oil level and contamination
Before starting the engine, check the oil level with the vehicle level. If you have already started the engine, stop it and wait 10 minutes before proceeding with the test.
Make sure the oil level is within the range shown in the figure.
If it is outside this range, bring it up to normal.
Check for white cloudiness or significant contamination in the oil.
If the oil becomes cloudy and white, it is highly likely that engine coolant has entered the oil. Find the cause and fix it.
While inserting the dipstick into the guide, apply oil to the handle rubber seal.
Oil leak
Check for oil leaks around the following areas:
- Oil pan;
- Oil pan drain plug;
- The switch of a control lamp of low pressure of oil;
- Oil filter;
- front cover;
- Front cylinder head cover;
- Contact surface between cylinder block and cylinder head;
- Contact surface between cylinder head and valve cover;
- Crankshaft oil seals (front and rear)
Oil pressure check
Caution: Do not burn yourself with hot engine oil.
Oil pressure should be checked in neutral position.
1. Check the oil level. See above «Oil level and contamination».
2. Turn out the oil filter. See section «Oil filter».
3. Unscrew the low oil pressure warning light switch using the long socket (suitable special tool).
4. Connect oil pressure gauge and hose (special tool).
5. Screw in the oil filter. See section «Oil filter».
6. After warming up the engine, check that the oil pressure matches the engine speed.
Note: When the engine oil temperature is low, the oil pressure increases.
Engine oil pressure (oil temperature 80°C)
Engine speed (rpm) | Speed x.x. | 2000 | 6000 |
Approx., pressure, kPa (kg/cm2) | Approx. 44.1 (0,45) or more | Approx. 265 (2,7) or or more | Approx. 373 (3,8) or more |
If the pressure is significantly different from the specified, check for oil leakage in the engine oil passage and oil pump.
7. After completing the test, screw the low oil pressure warning light switch back into place as follows:
- A. Remove the old sealant from the switch and from the mounting hole on the motor.
- b. Apply sealant and tighten the switch to the correct torque.
Use branded sealant or equivalent.
Tightening torque: 18.7-20.5 Nm (1.9-2.0 kg m).
Caution: Do not burn yourself on a hot engine or hot engine oil.
