I've been researching mod/con boilers lately and there are two decent forums to try if you need more info -
heatinghelp.com and the boiler section of doityourself.com is actually pretty good on older boiler tech
Good luck!

Finally got around to doing this just now. 
My expansion tank is definitely full of water. It's going to be a slow draining process because there is no way to let air into the tank so it will drain. I can't do it with a hose at all, I have to put a bucket under the drain and then jiggle the tank back a forth a bit so it will suck air in through the drain more often. If I let it sit it will only suck air every 15 seconds or so and let out about a tablespoon of water with each burp.
I'm sure this is the problem though. thanks again
