I posted a thread under overheating, but nobody has any advice. What do I do? Need to get car ready for tonights race.

 

I own a '94 Eclipse with a 2.0 DOHC non turbo. I race it at the local track here in Iowa. Dirt track that is. The last three races I have overheated. The first race, I thought it was the alternator cause I lost a belt, same thing on the second race. I replaced the alternator and that is fine now. But at third race, overheated again. This week I replaced the thermostat, radiator cap(went to a 16psi instead of 13psi) and but a brand new radiator in it. I did not give it a chance to overheat this time by watching the overfill tank. Which my overfill tank is just a 20oz. water bottle. Tonight I messed with it some more. I noticed that it bubbles in the overfill tank, like it is pushing air into the tank and it fills up. I took the radiator cap off and let some of the coolant overflow out of the top of the thermo housing. I have been told by certain people that it might be a head gasket? I rented some tools from the local autozone and nothing is showing exhaust fumes in the coolant. What do I do? I did notice one thing, this whole time it idled for an hour it did not overheat. But my check engine light stayed on after the motor warmed up. Nothing from the exhaust either. If it is air trapped how do I burp it or is it a head gasket? I want to get this fixed right away cause another race tonight and do not want to put anymore stress on the engine.
