I try to figure out how to repair this thing myself as much as I can, but this one is out of my league. I've had an antifreeze leak for a while (although the van has sat idle for the past year). It's coming from near the back of the engine, and not from any hoses that I can see. I got under it, and still don't see anything (although I'm not sure what I'm looking for). From reading around online I'm guessing maybe the head gaskets? Are there any other possibilities, and could anyone tell me roughly how much I could expect to pay for the repair? I need to figure out whether I pay to get it back in shape, or take it to the junkyard. It still runs very well, so I'm hoping it's not much.
Any help is very much appreciated.
