I hope this isn't a head gasket, but when I start my car, white smoke billows out. After it warms up for a minute or so, the smoke goes away. I know I'm burning colant, but there is no sign of coolant in oil and the spark plugs (front 3) look good. If I were burnging the coolant in the cylinders, I would expect the white smoke to continue until I turn the car off and coolant in the oil. This is not the case.
Any ideas?
