I remember once my friend put a cold air intake on his ford probe. For some reason after he put it on, there was white smoke coming out the back. Head gasket was fine. I am not exactly sure why it happened or why im posting this here, but it just goes to show it could be other things.
Slow down there. White smoke that instantly dissipates is coolant. It will also have a very distinctive odor to it (think of burnt marshmallows mixed with the normal coolant smell).
However white smoke that does not instantly dissipate is due to a lean condition. pull your spark plugs and if you see an overly white porcelin with a white powdery substance your running very lean.
Your compression should be higher than 130 up to 175. If the motor is cold it will be closer to 130 as the rings might not be completely seated. All cylinders should be within 15psi of each other regardless of the pressure they pump up to.
