Seal leak

Well my seal leak hasn’t gotten any worse since this last post.I cleaned area up and put a threaded garden hose connector from bell housing to a hose which goes to a gallon water bottle that lays in bilge.keeps bilge clean and I can monitor how much oil goes through there. I’m getting ready to change oil and was told that adding brake fluid could swell seal then change oil.not sure if it’s a good idea or waste of time.not sure if there are any other products that might work.Bill

3/4″ pipe plug on the bottom of the bell housing in a marine application , IMO, is a true “couch engineer at work” again, as he has ZERO field experience with what happens or can happen in the bilge of a boat.. ”Long story”, but just remove it and think no further..

Leak

Ok found plug at hardware store and closed that plug.realy can’t see anything better than those pictures because it’s at the bottom of my engine.two questions. What is the purpose of that plug and should any oil be in that area.engine is a Cummings 480 ce.Tony would u have any input to that. Bill

Leak

Was able to borrow a camera with scope on it and discovered the hole had no plug in it on port side and stbd had plug in it.does anyone know where I can pick up this plug. Looks to be threaded.Bill
