Picking up the coach from the Detroit Diesel gurus in the morning. The lowdown is that they stuffed a midget up behind the engine and found two (2) diesel leaks and two oil leaks (imagine that). One was the aforementioned return line and the other was the aforementioned plug in the back of the head.
The line has been changed, but they say to tighten up the plug, they have to pull the head because the bell housing interferes with it. I say that pulling the head off just leads to a bunch of future problems, so I have opted to see how much the leak was taken care of by changing out the hose and go from there. I am also thinking about making a special allen wrench to slide between the head and housing to see if I can get a couple of turns on the plug. A tool that looks like a slim jim with a stub allen wrench piece welded onto it. That has to be worth a try.
The oil leaks turned out to be the clamp on the breather tube and one of the valve covers. Oil and fuel consumption should abate. Sweet.
So the cooling system is flushed and filled with new PowerCool, the oil changed and the power steering pump is new, so if the bus gods are smiling on me, we are about 11 days from launching for the left coast.
If the vintage 8V92 will cut and tie every bale for another 4700 miles, we should be in good shape.:)

Jerry, can you get a picture of the loose plug. I like the idea of the special tool. Go for it.
If that doesn't work could you clean the area real good and apply a dollop of " DEVCON" over the top. It is a metal fortified epoxy. Mc Master Carr or Grainger or a bearing supplier should have it. Different grades for different tasks.
Degrease with tooth brush and acetone or MEK,( aerosol break cleaner) then wire brush (small like tooth brush, or round wound on twisted wire shaft in electric drill) degrease again and blow dry, and apply material.:eek:
If you had one a small sand blast of the area would be best.:p
Don't forget SHOW and TELL! :D
