Best Answer

A very small amount of white smoke at startup is normal and is nothing more than condensation in the winter. However combined with a loss of coolant with no apparent leak, overheating, white foamy substance on the underside of the oil fill cap, or overfull oil level, means you have a blown head gasket and or cracked head.

Yesterday you just had your oil changed in your 2007 mustang GT This morning a puff of white smoke came out the exhaust as you started it No smoke afterwards Why did it do that?

White smoke in the exhaust means water is being burned in the engine. A small puff of white smoke the first time you start a car in the morning is normal. Water condenses in the intake, and engine and when you firsts start the engine it burns off producing a puff of white smoke. It is nothing to concern yourself with unless the car is constantly blowing white smoke.
