I replaced the motor mounts. The pipes no longer hit the bottom of the opening but I dont like seeing where they have hit in the past. I just want to clean up the deformed area along the bottom. The rest of the opening is great. Right now I have 1/2" clearance on top and 1/2" clearance on bottom. If I enlarge the bottom by 1/4" it gets rid of the damaged area plus I can remove a shim from the passenger side motor mount and center the pipe in the opening. I know I am splitting hairs but I am bored.

If the pipe has insufficient clearance from the bottom of the pass side hole AND you have soft motor mounts, this could be the problem. (Been there...). Fix with polyurethane motor mounts (as someone suggested above) and make sure you have at least 3/4" between the pipe and bottom of the hole. Good luck.
