82toy - No bubbles.
cmdeshon - Actually bought two thermostats at different times on accident, tested both, both worked fine out of the car, car overheats with either.

I bypassed the heater core before and had overheating issues too. Having a heater core can help to dissipate heat and avoid BHG while you track down the issue. Since you've looped lines, heater control valve is not in question, though adding water wetter might help. Some 5m's seem to be more prone to run hot. GLWT

I've had the lines looped for the year or so I've had this engine, and never had any issue before. water wetter might help if it were just running hot, but it's full blown overheating after just minutes of driving.

Ph the coolant if acidic then most likely a BHG, exhaust gases getting into the cooling system...Regards,

well, opened the cap after some testing today and found that it was coated with sticky black gunk and that now when doing 82toy's bubble test, I have bubbles. ah, C'est la vie...
Thanks for the help everyone, learned a lot this go around.

Ha and LUCKY YOU get to learn MORE!!
Replacing a head gasket isn't too tough, many of us have done it, there are ample threads about it, you are in good hands. You can leave a lot of the upper items on, Intake/Exhaust, if you have an engine hoist available to you (you can probably rent one somewhere if Not), Good Luck let us know what you decide to do.

I've actually done the head gasket a couple of times. Just takes 2 guys and an hour or so. Fun times.

Well then you can certainly do it faster than I can, good for you.
It took me two days with an engine hoist and my wife! LOL. One day to get it off and one day to put it back on (probably because she isn't that good with a wrench) JK. I wasn't in any hurry and didn't want to mess anything up.
