Answer
Wendi,
    Well, unfortunately, the clue here is in the way that it just keeps bubbling when you are trying to get all the air out of the system. Generally this means that small amounts of compression from the motor are getting into the water system, which is usually an indicator of a bad or blown head gasket. When a head gasket goes, it will not always present it's self with a leak or water in the oil. Unfortunately, when these cars get hot too much, or too hot a time or two, they also have the tendancy to warp the head. It really sounds to me - especially with all of the new parts and work you have done - that it would about have to be the head gasket.
