Tore open my transfer case tonight to start my SYE. I think the last guy that was in there applied the RTV with a hose and high pressure pump. Entire filter body and area around oil pump were filled. Anyway, noticed that the skirt of metal around the pick up tube port is cracked off. Again, last guy basically caulked it place with RTV. The O-ring does seat all the way in, but should I be worried enough to replace it? Can't image there's any substantial pressure there, with just a push in fitting.
