Planenut, I will do that if I need to split that case again. I feel very foolish to not have looked for a seal in the Alt.Parts List first so I would have known the part was unknown. I literally let the opportunity slip through my fingers when I was cleaning that “O” ring and thought to myself , should I measure it? I assumed, bad thing to do, that someone had done so. I had the calipers on the bench and had that part laid out and just didn’t do it. Damn!

Kankel, I split the case to drill and tap the top of the case for a remote fill and the return line from the oil cooler.

BTW, No RTV is used in that joint, just the rubber "O" ring.
