white smoke and lots of it!

[ther1pper]

well i was driving and floored it pretty hard in first gear and then i heard a loud pop and the next thing u know white smoke is pileing out of my exhaust, the sides of the hood, and even into my car. first thing that came to mind was a blown turbo. cher was over the other day and we took the intake off and looked at the turbo and the wheel had very little play back and fourth and thats it so i dont think that, that could cause that much smoke. cher said it could posably be a blown head gasket, well befor i go on, i can drive the car fine but once i build boost smoke just piles out, well i can build boost fine in first gear w/out smoke, but when i switch to anohter gear it really piles out. so cher said to run a compression test. so today at work i ran a compression test and it was fine, i think that max hd it went to was 4. iam kinda stumped, and not that knowledgable, and iam goin to florida on the 27th of this month, so im trying to get my car running good. help is needed pls.
