Tennessee has hit on your biggest clue. Check the LEVEL of your oil. Are you substantially over-full? If so, that's where your coolant is going. Glycol is extremely hard on the engine bearings, so don't drive it this way except for a genuine emergency situation!
If your oil level is about normal, maybe you got "lucky" and just have an external coolant leak.
Let us know.

My dipstick level was about 2-3 inches above where it should be, it didn't look like a milkshake which is what I thought it should look like too. Maybe its the low rpms of a diesel? When I draned the oil into a 10gallon pan it filled it up to about 7 gallons or so. I'm going to order a reseal kit for the oil cooler and start there when I get my next day off on tuesday. I have another vehicle to drive so my stroker ain't going anywhere till I figure it out. Thanks...
So is there no possibility that it could be a head gasket or head like in gassers?
Oh it most definitely is a possibility. I just didn't want to cause a panic until some of the "easier" possibilities were checked. Popping a headgasket on a stock or near stock PSD is almost unheard of. The 7.3 anyways, the 6.0's do it all the time.
Cuda_jim. I am very familiar with those particular passeges of the service manual, thank you for reposting them. What all that means is that the oil cooler is a full flow unit and does much to confirm my original hypothesis as coolant would only be able to escape into the oil with hot coolant (under pressure) and the engine shut off. With the oil pump running it will overpressure the coolant and push it the other way.
Cookie, thanks for the link to the front cover forum, this sounds logical to me. I must admit that I havent stayed on top of my antifreeze. I have only changed it once during the 50,000 miles of the new engine. Going to get started tommorrow on the teardown. The front cover is probably aluminium so it makes sense to me to start there. I'll let you know after I get there. Thanks a whole bunch. >>Danny<<
Wel I got the water pump off and no pinholes in the casting behind it. I'm stuck and don't know where to go from here, do I go for the oil cooler. There is no oil in the coolant. I'm kinda frustrated.... after a good mornings work. Thanks...
Man I don't like this thread at all!! To me this is a real scare story. My truck is so perfect because I'm thinking I maintain the hell out of it. But ya know what? I never have changed my coolant. Close to 180,000 miles now. The water pump was replaced under warranty way back when. I am going to do the anti-freeze pronto. Please keep us informed of what you come up with. I'm a lot of help, huh?

Banshee, I agree with Mark, this sucks. I bought my rig used and have not changed or even checked diddley since as far as coolant. Now I only have 57k on it but I'm probably asking for trouble with the age.
I woudn't want to tell you to start pulling heads, but, I didn't have a whole lot of faith in the earlier posts concerning the oil cooler and water pump based on the amount of coolant you were losing into the oil pan. You be the judge. That's the old school reason to leak out like that and since nobody thinks the injector cups could cause this, what else could it be? Best of luck with it.

Banshee,
here's a little help on the oil cooler as far as parts and how to. If you are going to replace those O-rings, here's a little advice. Don't go to the Stealership and buy those, like I did and pay $100. Go here and they are alot , alot cheaper. Didn't find those till I already purchased some.http://catalog.powerstrokeshop.com/...&catalogid=4411
well i think you should pull the cooler, have it pressure tested for internal leaks and if all good replace orings and see where that leaves you before you pull the heads. my .02
I am the first to admit that I know a lot more about gas engines than diesel, but is not a leak down test through the glow plug holes possible. That would find a head gasket leak, would it not? Has to be a lot simpler than pulling heads, especially when you only have a 50/50 chance of choosing the correct one to pull first.

Are you sure there are no external leaks? Seems to me that, that much coolant loss would create a bigger mess in the crankcase oil than simply giving it a green tint.

I'm too pooped to read all this but here I go with an idea.
I'd look at the oil fill to see if there is mayo there ... I believe the coolant will evaporate to the higher locations first.
If thats good, I'd look at the water pump weephole ... thats where i had my problem and couldnt find it at first. Then start looking around the head gasket edges for staining, the hot motor might be evaporating the leak.
If all else fails, get an oil sample and tell them what you're looking for.
I thought the injectors had o rings on them to seal coolant in the head from leaking down the cylinders which might be burned out the backend, just enough to hide it from being found.
Could also let it sit for the night and try draining out some oil from the sump, the coolant will come out first by just letting it trickle from the drain plug.
Boy, I sure bounced around on this one,,, must be pooped.
good luck. Digger

if your crankcase is that overfull it would look like a milk shake guarenteed!!! especially if you have been running it. I think you might have some other problems along with your loss of AF. Did the oil smell like AF???? or Fuel???? Oil????
Ths oil is definately full of antifreeze, the oil doesn't feel lubricious when you smear it between your fingers. No fuel smell in the oil, just af. I have the oil cooler into a shop having it pressure tested. Hopefully they find a hole. If that isn't the case then the motor will be coming out I suppose. he dipstick was overfull by about 2-3". I'm pretty well bummed out on ford right now, considering this is my second motor, at least they paid for the first one! lol This one is on me cause my truck is 6 years old but only has 70,000mi on it. 50,000 on the new motor. Thanks a bunch for the help....
