ok heres whats up.

I just went and drained my radiator, checked my thermostat, its fine. refilled and burped. when i rev the motor up though it would bubble up a little bit but that seemed normal to me because of the circulation. it would bubble just sitting there idling anymore though so i capped it and drove. I drove for about 15 minutes just like this morning. then i beat the shit out of it. Now normally when i would really get on it hard, the needle would rise to exactly half way then fall back to normal temp. thats what it was doing this time. it would go to about half and then float slowly back to normal temp. I dont know if its cause im using a stock dual core radiator or not, but my old motor did that as well. When i got back, the needle was at normal temp and i popped the reservoir and the water level was near the top and small bubbles were coming out, does pressure bleed off into the catch can, im guessing so. the revervoir was about half full when i left to test drive it, i guesss when it cools off it will get sucked back in. i know that i saw wetness on the upper hose from it spattering out of the catch can lid which wiggles anyways and doesnt make a seal. its the kind that just twist about an 1/8 of a turn to seal.
