You probably have a little oil seeping into the combustion chamber while the engine is off. Once you start the engine, this oil is burned and causes the smoke you see.
WHERE IS THE SMOKE COMING FROM ?
Black smoke coming out of the exhaust of a car is usually due to oil being burned in the engine's cylinders. This can be caused by a worn piston ring or rings.
Car maintenance is very important for a smooth ride. When there is white smoke coming out of the exhaust, it is usually an indication of water in the engine.
If you have knocking from the engine and smoke from the exhaust then you have far more problems than the car just not starting. Sick professional help immediately.
White smoke coming from the engine can mean many different things. One such thing is that your car may have a blown head gasket or that oil is burning in the engine.
Smoke could be coming from the vents of your car for a number of reasons. You may have an internal car fire.
White smoke is usually vaporized coolant. You may have a blown gasket or a crack somewhere.
If your engine is blowing blue smoke your engine is burning oil.If the smoke is present on acceleration, the piston rings are bad.If smoke is present on deceleration, then the valve guide seals are bad.
Have vehicle scanned to determine problem
White or gray smoke coming out from under the hood of a car could be the result of a small water leak spraying water on a hot engine. A running engine is naturally hot enough to create steam when water hits it.
