Well i had no coolant in the oil or anything and i wasnt losing any power and i put my car on the dyno and put down good hp for my mods. But on the second pull my system go pressurized and was blowing out the overflow tank. i caught it before it got to bad and saved my head, my friend bought an evo with a blown headgasket and had to deck the head because it was so bad and warped

But now I'm wondering why this got moved to the newbie/Faq. There are at least 10 other "coolant overflowing" threads in the Evo General describing similar issues with the cooling system and/or head gasket. I guess I am a noob again.

I have an '03 as well and got a recall notice that the radiator fan controller is failing causing your car to overheat, because your fan doesnt turn on when it should and turns on when it shouldn't. Dont know if you figured out the problem yet but i would look into that. It only takes like 15 minutes to replace. Good luck and hope you find out the problem.

So for now, I'm trying a few more things. We suspect it may still be air trapped in the cooling system, since that's when the problem first emerged. I'm going to spend the next few days flushing the cooling system to try to purge more air. Then after that a cooling system pressure test. Then a cylinder compression test. Then depending on what those tell me, it could be headgasket time. Blah.
