Sounds like a head gasket. If it is pushing coolant, you can almost bet thats what the problem is. The only other thing that comes to mind is that you might have pockets of air in the cooling system. Based on everything else you have said, Im leaning towards the headgasket.

Good luck.

PS- if it is the head gasket, make sure to have the cylinder head checked that it doesn't need to be planed/milled or you will be doing the headgasket again soon.
