Best Answer

You will see steam come from the tailpipe in the winter which is caused by the hot exhaust coming from the engine making contact with the cold metal in the exhaust system. This is normal and no cause for alarm. However if the white smoke does not dissipate almost instantly and seems to continue you may have a blown head gasket. If the exhaust smells sweet you almost certainly have a problem and the gasket is blown. A blown gasket will destroy the engine in time. If you are not sure have it looked at by a professional.
