Hey guys,

So a coworker of mine’s sister bought a 2008 MINI Cooper two days ago. I don’t know if its an S or not, haven’t even seen the car, but apparently when she tried to start it up yesterday - in 70 degree weather - white smoke started billowing out. She left it running for an hour and it continued to smoke, albeit not nearly as heavily. Half way into a 2 hour drive, it started belching huge plumes of white smoke again.

My coworker asked me what the most likely cause of this is, because the dealer is telling her its carbon buildup. Personally that sounds like a head gasket to me. Any thoughts, everyone?
