1. Coolant Leak:
- Look for low coolant levels.
- Inspect hoses and clamps for leaks.
- A blown head gasket or cracked cylinder head can also cause this issue.
2. Faulty Fuel Injectors:
- Excess fuel entering the combustion chamber due to a bad injector can result in white smoke.
3. Worn Piston Rings:
- Old or worn-out piston rings can let oil seep into the cylinders.
4. Blocked PCV Valve:
- White smoke and rough idling suggest the PCV valve (Positive Crankcase Ventilation) that regulates airflow may be restricted.
5. Head Gasket Failure:
- If coolant mixes with engine oil due to a compromised head gasket, you'll see white smoke and low coolant levels.
