Engine blowing smoke

One reason for white smoke is very common and completely harmless. A car engine can smoke for several reasons. This could be caused by valve stem seals, worn rings, a plugged PCV valve, not changing the oil for extended periods, too high of an oil level or transmission fluid being sucked into the intake manifold from a bad vacuum modulator.

Different colors of smoke can indicate different problems with your engine. Blowing white smoke is a red flag for your diesel engine , yet we see this happen all the time to our customers.

Engine oil capacity is dependent on your specific engine model and can be determined by checking the Oil Recommendation FAQ. An under-sized piston leads to blow by when the engine is cold.

WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned. Some causes of this include. This typically occurs due to the engine being too cool to burn the fuel, often resulting from low compression in one cylinder, problems with the fuel injection timing or a defective fuel injector.

Worn engine is another culprit responsible for blue smoke from exhaust. Each engine has pistons which are move up and down a cylinder. Each piston has metal rings round its side like bracelets.

The function of these rings is to help the piston forming a tight seal against the cylinder.
