The motor mounts were shot, and I guess the vibrations caused the K-member to wear through a section of the oil pan. This one isn't broken through at all, but I don't know if I should bother using it, or just get another one. This is the second one too. The one that was originally on this engine that I'm rebuilding was actually cracked all the way through, so I know that one is junk. This one isn't all the way through, but it is worn down. I still have the one on the original motor, which is still in the car, and I have no idea what that one looks like. I also have another motor in another car that I could pull out and see how that one looks. What do you people think, would this be OK to put back in, or should I junk it and hope one of my other ones is still good?
