TROUBLESHOOTING
31) Check Engine Oil Leakage
32) Check Engine Oil Consumption Amount
Check oil consumption amount based on the oil level lowering and data from the previous inspection.
Excessive oil consumption causes carbon deposits on the spark plug electrode, which leads to spark failure and
eventually causes an engine start failure.
Such a problem is considered to be caused by the valve drive system (valve stem seal) failure or piston ring
failure.
1. Check the engine block and the gasket for oil leakage.
2. Check if the engine oil hose clamps are attached securely.
3. Check the engine oil hoses and hose connections for
leakage.
4. Check the sub oil reservoir for oil leakage.
