my car smokes white smoke will idling and taking off from first. also when shifting gears, when you put your foot back on the gas, it smokes for a short while. it only does this when boosting so im assuming its my turbo. anyone who has had this problem, please give me some info on what and what not to do. how much will this cost to get fixed? any info is appreciated. thanks guys.

The turbo would have to be really screwed to leak coolant, as in a cracked water jacket in the bearing housing. Not impossible, but probably less likely than other things. Have you checked all the coolant lines for any obvious leaks? Heater lines, lines to and from the turbo, lines to and from the oil cooler, lines to and from the throttle body elbow, main radiator hoses. Check around the thermostat and the cap for leaks. If all these are clean then it very well may be the head gasket. Usually a car with a blown head gasket won't run very well, like Rob said. I'd check the compression on it before tearing it all apart to find that the head gasket is still intact...speaking from experience here. rolleyes.gif

When the seals on my turbo blew a while back, it smoked light blue almost white under the hood and out of the exhaust pipe. You might want to check your turbo. Try to move the shaft back and forth. If there is a lot of play, more than approx. two or three millimeters your turbo oil seals may have blown out. Another good indication is if your car simply won't build boost.
