I hate to hear of your headaches, I just had to go through with this last month on my '02 with 102k miles.
There is not a TSB for this with Ford, and you are over your 100,000 warranty with this as well. This is a very common problem in the East Coast and "Rust Belt" areas, as well as the valve cover and fuel lines rusting through.
You will have to pull the engine to change the Oil Pan on 99-03 Superduty Trucks, there is not enough clearance between the pan and the cross member to pull the pan out. (Even with the turbo off and the engine raised against the firewall). Secondly, the pan and gasket must be applied with the engine turned upside down, as any oil seeping down inside the block will ruin the seal and the leaks will start!!
There isn't a whole lot than you can do for an inexpensive or temporary fixes; I researched everything from epoxy coating the pan, 2 piece replacements, even having a fiberglass replacement made.
Find a good local diesel shop to do the work and stay away from the dealers, my local guy did the whole job in under 12 hours and the dealers wanted 23-30 hours at rate!
Be prepared to find a lot of other small problems while pulling the engine out to replace the oil pan, like:
1. Rusted Fuel lines
2. Radiator Hoses, Lower and Upper
3.Thermostat and Housing
4.Glow Plugs and Valve Cover Gaskets
5.Starter ( The terminals were corroded so badly that they broke off when turned)
6. Water Pump and Antifreeze change
7. Turbo pedestal O-Rings
All said and done, I was out $2750 for parts($1490) and labor($1260). And a case of beer......
Start to save you pennies now and hide the receipts from the wife.....
