Something tells me a rebuild will take more than a weekend and besides, The Mitty > CCVT car show.

I'm going to try one more bleeding technique as suggested by the Haynes manual, which involves running without the radiator cap with the car cold. If that doesn't do anything then I guess it's time for a rebuild. I can't think of any other reason why I'm getting a constant stream of gases, occasionally accompanied with coolant, flowing into the overflow bottle other than a water jacket o-ring or housing failure.

Bottom line: is there any way this could be attributed to a bad thermostat or leaking radiator/water hoses? If not, like mentioned above, it looks like rebuild time.
