• If the engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken
parts.
OIL LEAKAGE
Check for oil leakage around the following areas:
•Oil pan
• Oil pan drain plug
• Oil pressure switch
• Oil filter
• Oil cooler
• Intake valve timing control cover
• Intake valve timing control solenoid valve
• Front cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seal (front and rear)
OIL PRESSURE CHECK
WARNING:

Unit: (US qt, Imp qt)
CAUTION:
• The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.
• Always use the oil level gauge to determine when the proper amount of engine oil is in the engine.
8. Warm up engine and check area around drain plug and oil filter for oil leakage.
9. Stop engine and wait for 10 minutes.
10. Check engine oil level. Refer to LU-8, "
Inspection".
