Re: car overheats

Ok, I looked at the car for a few minutes tonight. I started it up and let it run with the radiator cap off. After 10 minutes, the car was still right in the center of the gauge. I sat the car at a constant rev for a little to warm it up more and I noticed that when I reved the car, the coolant level would lower in the water neck. When I let off the throttle, It would come up to the top and dump a little out. When the car was heated up more, I tried it and some white shit came up (possibly little bubbles) and some larger bubbles came out. This happened each time when the car was warmed up. After about 20 minutes, I shut the car off and the coolant, which was at the top of the water neck, dissapeared and was not visable anymore under the radiator cap.

My original guess was that the car has a warped head. Comp was 140-140-130-90. James blew coolant past the HG on a pull at 25psi. My guess is that when the car heats up, air is sucked into the coolant passages by the HG. The car has ARPs torqued correctly and blew coolant on the second pull. Any second opinions???
