Glow plug dead shorted to ground
 

Hello,
I have a really potentially serious problem with a 240D for which I am hoping to get some advice or directions from more knowledgeable people than my self. The problem started with the glow plug in the second position w/ respect to the positive side of the circuit, this glow plug only 2 months old dead shorted to ground and exposed the first glow plug to 50 amps at 12VDC until the fuse blew, the ring element burned open and apparently there is a small piece of it left in my cylinder because I can hear it, of course I have not started the engine since realizing that something is very wrong and that this motor never made any sounds like that ever. My question is: what will be the best and most economical way to possibly resolve this problem?
I have an estimate of 893.00 to pull the head including parts. This is a lot more money than I have right now, and of course might only reveal serious engine damage which might total the car.
I really appreciate any of your thoughts or suggestions on the issue.
