3. Worn Piston Rings: Worn piston rings can cause oil to leak into the combustion chamber, which can result in white smoke coming from the exhaust. The piston rings are responsible for sealing the combustion chamber and preventing oil from entering it. If the rings are worn, oil can leak into the chamber and mix with the fuel, causing white smoke.

4. Clogged Air Filter: A clogged air filter can cause the engine to run rich, which can result in white smoke coming from the exhaust. The air filter is responsible for preventing dust and other particles from entering the engine. If it becomes clogged, it can restrict airflow to the engine and cause it to run rich.

5. Faulty Fuel Injectors: Faulty fuel injectors can also cause white smoke from the exhaust. If the injectors are not working properly, they can cause the engine to run rich, which can result in white smoke. The injectors are responsible for delivering fuel to the combustion chamber, and if they are not functioning properly, they can cause a number of issues.
