is there any coolant left in the radiator at all after it drains down? The oil cooler is lower that most of the radiator so it would drain the radiator almost complete if it is the problem, the water pump impeller sits around the center of the radiator so the water level in the radiator would only drain down to the level of the water pump....folllowing that if it was a head gasket water would only drain down to the level of the head....
I'm not sure of an exact way to test how far down the radiator is draining other than filling it with hot water and seeing where the heat ends on the side of the radiator after it drains down........the level of the water in the radiator will give you an idea of the physical location of the leak in the engine.......does that make sense? its early, I can picture how I would do this but my communication skills may be lacking right now.

I guess I'm gonna have to pull the engine and see. I have to find a good diesel mechanic though if I pull it. I cant loose any more work time guessing what it might be.
Around here most diesels are large equipment and dump trucks. Mechanics are around but the knowledge of them is not experience, just books.
I have a large equipmeent guy that I was buying my Stanadyne additive from and he said he has a guy who works on PSD's. I'm gonna call him Monday and see.
Now the question is do I just take it apart and see what's wrong (I feel I have to now) or just buy the bottom end and re-install all my stuff
The wife says sell it and buy another one but I think that's just asking for more problems
Just for the record here, my son car's T-stat stuck shut and blew the expansion tank cap and he broke down. I was just out buying parts for his car

What about taking the oil cooler of & rigg up those blow-up pipe plugs to do a leak test? At the rate of leak you got it wouldn't take much pressure to show up. Hate to see you take it to someone & get raped, But Marty on PSN knows these things inside out, good guy & he is not far Elkton, MD. If it comes down to that I might be able haul it for you

Ok here we go.
I bought the Test Ball and hose clamps
Took the cooler back out and popped it apart
Cleaned the cooler but left the oil/water(milk) in cooler
Here's the end cleaned up
Cut the test ball in half and slide on each end and tighten
Attach bike pump and start pumping
This is all set up .
I pumped it to 5 lbs and I should have seen something either a bubble or something . The cooler is slippery but I pumped it up till the end blew off . Sounds like a shot gun when it blew off .
That's it . Tested and not bad . At least I know it's not the cooler anyway
I found several places within 30 minutes from me that work on diesels . I'm gonna do some interviewing tomorrow . I also have to talk to CJ and see if Marty has any openings and how long it would take to pull it apart
I'll keep you posted . I think that's it for now
