What Can Cause An Engine To Smoke?

Valve stem seals, worn rings, a closed PCV valve, not changing the oil for lengthy periods of time, a high oil level, or transmission fluid being sucked into the intake manifold as a result of a faulty vacuum modulator can all cause this.

Overheating in automobile engines frequently results in the emission of smoke. A defective wire casing, hot residues on the engine block, and overheated liquids such as oil, transmission fluid, and braking fluid are all possible causes. Alternatively, a problem with your cooling system or insufficient lubrication in your engine might be the cause of your problem.
