Sorry, I came in late in the game. I read your thread at work while waiting on other things. I'd be interested to see what happens with the pressure bleeding. If you have air in the system it will bleed out unless new air is being introduced into the system. You should have seen improvements if you were bleeding air out. If you do go with the pressure bleeding have them hold pressure on the system for a while before cracking a bleeder to see if they can find a leak.
