We have a 1988 Astro, and have been running into the same problem. As it turns out, the freeze plugs are being eroded from the inside, and have to be removed and replaced. Out mechanic says he's nervous that the engine block itself may have the same thing happening to it, so he's pretty careful when he changes the things. So far we've only replace the plugs as the problem occurs, and not pulled all of them for replacement.
