Alright kids, heres the update.
Parked the car on up a hill today to let the radiator cap become the highest point in the cooling system. Turned it on and let it warm up. Added water to the system. There were defenatly bubbles coming out of it. A lot of them. After it reached operating temperature, i topped off the system, blipped the throttle a couple of times, and put the cap back on. Went for 10 mile spin, beating the car pretty hard, boosting, chucking it in turns, all of it.
Needle never moved off of operating temp. YAY!
I stopped once to make sure my overflow fill had stayed in the catch can. It hadn't, and it was spewing coolant down the intercooler pipes. Put it back in and drove home. Shut the car off and let it cool down.
Took the radiator cap back off and checked. The coolant level had dropped about 1L. Here is where i'm unsure. I don't know if the drop is from the coolant simply being squirted out of the overflow (and since it fell out of the coolant tank, there was nothing to suck back in but air). That is what i want to tell myself.
The other possibility being my headgasket is fuxored. My car doesn't smell like coolant, and seems to run just dandy. No smoke, leaks (other than the rear main seal), nuthin.
I am going to duct tape the overflow tube into the overflow can and redo the process again, but is there any secondary checks i can do to check if the headgasket is gone? I don't have the equipment for a compression check. Anything else that might be an indicator?
The last car i had that the headgasket went out on just smoked white smoke out of the tailpipe, so thats all i really have to go off of.
Thanks again for everyones input. You guys have already helped a lot!
