Ok I have heaps of white smoke pouring out my exhaust after long like 2hr ish drives boosting alot. It never happens normally only when i'm driving for a long time. It happens when i stop and its idling but fine when i start driving now i don't think and would be really surprised if its the head gasket because that got replace not long ago. Or dealt its the turbo because its only 10,000kms old brand new. my thoughts was it was just getting really hot but doesn't really seem to right. What could it be? ps. its a +t cracked piston or something? i duno its got no lack in performance though.
