A small amount of smoke or steam from the exhaust pipe of the car is normal at start up or under power.

In this case, bad seals or piston rings cause oil to leak into combustion chamber which then mixes with fuel and burns. The result is a white or light bluish smoke that comes out from exhaust manifold. Usually, it is water vapor or steam, since it is introduced into the chamber. For that reason, you will have the water dripping from the tailpipe. Drivers can also see the water in the fuel or a leak in the head gasket.

As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen. This is generally steam caused by condensation. Indicators of an internal coolant leak include billowing white exhaust smoke accompanied by a sweet odor or a low coolant reservoir level.

One cause of white smoke from the exhaust might be the engine leaking coolant. If the engine leaks coolant, it will be burned by the heat of the engine and then come out as smoke from the exhaust. A problem with antifreeze might also be causing white smoke to come from the exhaust. Antifreeze is used to stop your car from seizing up in cold weather. There may be several reasons for a car smoking white smoke from the exhaust.

When the engine is new, it will run fluently without any problems. White smoke from the exhaust is a sign of coolant entering the combustion chamber. With the excessive oil usage, it sounds like this engine has been destroyed by this coolant. It has mixed with the oil, and has ruined the engine.

Black Smoke Diesels are fuel-throttled engines, meaning that rpm is controlled solely by the amount of fuel that goes into the engine: The more fuel goes in, the more power the engine will make within the constraints of the oxygen present. A diesel engine in good condition should produce no visible smoke from the exhaust, under most operating conditions. A short puff of smoke when an engine is accelerated under load may be acceptable, due to the lag before the turbocharger speed and air flow is able to match the volume of diesel injected into the cylinders.
