Ok, went out and diagnosed a few things. Have oil in the anti-freeze but none in the oil. Ran engine for a minute and no compression appeared to build up in the radiator. Removed oil cooler and pressurized to 75psi and no leaks were found.

How so? It's either blown, or it is not blown.

Yes, but a blown engine would mean the car does not run. The car runs perfect now. No loss of power or anything. Will just overheat if run for any length of time.

did you notice in the cars for sale thread that i asked him to confirm if the car had been previously supercharged but he ignored my question?
maybe the owner had a thicker headgasket on the motor for the supercharger then replaced it by re-using the OEM headgasket so now it's not a perfect seal? just a thought anything is possible these days. good luck w/ your situation.

Sounds like you need a new OEM head gasket. I also would not rule out replacing the thermostat for grins.

a damaged gasket can be replaced relatively cheap and fast, a blown motor consist of mechanical damage(2 parts or more part trying occuplying same space), which is much more expensive to fix.(if worth fixing, at all)


it's like comparing a burn down house vs a house with a leaky bath tub, there's a difference in the scale, no?
