Ok so here is the problem. The Engine mount is rubbing on the pulley that runs the serpentine belt and making a nasty noise. Its not affecting the belt at the moment. I first changed the engine mount but then discovered the bracket that is attached to the engine and bridged to the mount is broken. (it had completely sheared in half) I found this part in a junkyard and replaced it. Now the center bolt holding on the bracket broke inside the engine so I was only able to attach it with 3 of the 4 bolts. All this was put back together and the engine ran perfectly for 3 days. The sound came back and the part had broken again in the same spot. Here is my question. What is causing the extra force to break this mount? Could it be that one of the other mounts is bad and it is putting too much pressure on the bracket? Or could it be that one bolt that broke off in the engine? I figured that the bracket had enough support with the other bolts so I am assuming that the problem is another mount I just want to confirm.

Any one else seen this break before?

Check other motor mounts and trans mounts. Chances are you have another one broken.
