I've had my 97 XJ for less than a year. When I was doing the oil pan and RMS, I noticed that the oil pan flange lip was dinged up. At first I wondered if I had done that, but then I saw a similar mark on the frame rail. I can't see any other evidence that the motor mount was broken, but I haven't taken the mount off yet. I am wondering if this is consistent with the mount coming loose from the block.
