So I just got my car tuned and ran it at the track once and already I may need to replace the head gasket. I lost coolant pretty fast and almost positive there are no leaks. At idle there are clouds of white smoke, other than that the car runs strong. Head gasket? yes? i was wondering if I re-torqued the head bolts- would that fix the problem? If not what would you suggest for a HG for a turbo car producing 300+ whp. If it matters its a H22. The motor was built and I thought the machine shop used a good thick HG? I dont know? Any help thanks
