one other thing i might add is the car still drives fine apart from the smoke, still boosts etc even though im not if i can help it at the moment....
The boost controller fell apart a few weeks ago so i had been running the boost through the external wastgate and was only pulling 10psi constantly but hooked up a new bleed valve today so the psi was back upto the high level and yer it started playing up... so i duno if i cooked something or it is the head gasket or what..
One more thing the radiator overflow tank was full to the top, usually only half full, the radiator it self was full as well so i was a bit worried about that fluid not being in the motor? :S
