While moving cars around in my driveway, I heard a nasty tapping sound in the engine compartment. As it turns out, the upper muffler bracket had broken. And the remaining piece hanging on the muffler was hitting the alternator blades. I can't figure out for the life of me what caused the bracket to break. The crack that goes thru isn't a clean snap. Nor is it a new fracture. Only a small portion was clean where it had just snapped. The remainder of the crack was caked in what looked like years of road grime. So evidently this isn't new damage. Since the DeLorean is my only car, I need to get this fixed. I've temporarily used a length of steel strap to hold the muffler up. I enlargened the hole to slide the welded post on the muffler into, and I bolted the other end to the coolant bottle bracket. It's not as high up as it was before, but at least the muffler is no longer resting on the rear portion of the chassis. In the meanwhile, I'll keep driving to a minimum, and will take it easy. I don't know if I can weld the bracket back together. But it doesn't matter anyhow since I don't have access to any welding equipment anyhow. So it looks like I'll be ordering a new bracket. Any idea as to what caused this? This wasn't a sudden fracture, it looks like it took a bit of time. When i get a chance, I'll go over the other brackets to check for any problems. -Robert vin 6585 "X"
