Re: Head gasket????

I would try driving it some first and see if coolant is disappearing. After we swapped the radiator cap and filled the coolant system, I did a couple pulls with the car fully warmed up and someone else watching the coolant overflow and on those runs they didn't see anything come out. The car didn't seem to be suffering from any overheating issues either.

Pushing coolant under boost is a fairly common problem on DSMs caused by non flat head/deck surfaces, bad install, knock, too much power/head lifting. They can drive normally and not lose any coolant or act like a blown HG, until you boost them and the coolant gets pushed to the overflow, but not sucked back in.

I wasn't sure on your car yet though, it wasn't just spraying out like crazy under boost, like a lot of cars that I have on the dyno.

It does smoke burnt oil way too much though. Could just be that old Mutt turbo. Hopefully not rings. The dipstick on your car was not secured in any special way and it didn't blow out during any pulls, so that is a good sign toward it hopefully not being rings causing the smoke.
