2. The fuel injector is damaged, and the carbon canister solenoid valve is damaged.

3. The oil has not been replaced for a long time or the quality or model of the oil does not meet the standard.

4. Oil leakage leads to oil shortage.

5. Effective oil pressure cannot be established, and no effective oil film is formed between components.
