Blue/grey smoke is usually oil. White smoke is usually coolant in the exhaust. IE: blown head gasket or something. note: if the smoke goes away after it runs for a minute it's oil runnung down the valves when it sits. Common problem, won't hurt anything.
grey exhaust smoke is caused by your engine burning oil during the combustion process. this could be caused by a piston ring that doesnt properly seal, or another leak in your engine.
Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.
In most cases white smoke means you are burning gasoline inefficiently, black and gray are usually oil, however, that's the extent of my knowledge.
if it is white smoke engine need to rebuilt.
White smoke means head gasket, cracked head or equivelant.
AnswerThere are several possible answers to what makes a car smoke. If the smoke is blue-black the engine is burning oil. This could be caused by worn rings or valve guides. If the smoke is gray black it is caused by a to rich gas mixture. This could be caused by a malfunctioning choke or injector, oxygen sensor, or other fuel related equipment. If the smoke is gray white it could be a blown head gasket or cracked block, allowing coolant to get into the exhaust system. Other causes of smoking could be an oil leak that is dripping on to the exhaust pipe or muffler.
Sounds like you are getting coolant into a cylinder , is your coolant level dropping ? Could be a bad head gasket , warped or cracked head
Piston rings or Rich oil .
White, water vapor. Gray/black unburned gasoline. Blueish, burning oil.
It can be a number of things, but the most common problem is worn valve guides.
Black smoke means you're burning fuel, blue smoke, you're burning oil, white smoke, you're burning coolant.

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.
No, it will not cause smoke from the exhaust pipe. However the leaking oil can drip on the exhaust manifold where it will be burnt and smoke.
the "smoke" is always there when you breathe in the morning, when its cold, you see like a mist, that what that is, its just you usually cant see it
Water vapour due to condensation in the exhaust pipe.

White smoke at start up is due to moisture in the exhaust or on a diesel it can be normal due to the engine being cold.White smoke at start up is due to moisture in the exhaust or on a diesel it can be normal due to the engine being cold.
If the smoke is black it could be caused by a faulty fuel pressure regulator which could be causing the engine to get too much fuel.
