Think it's saveable? A good back flush maybe? I guess it couldn't hurt to try.

A flush will never clear a clogged cooler, and yours is clogged bad. Have you popped the EGR valve off yet and checked for moisture? You need to know if the EGR cooler has ruptured, and that is a good easy way to check.
If you haven't seen any of the other signs, get the cooler rebuilt soon. Ford offers a rebuild kit now for around $200 and change that only replaces the internals. Since you'll have the upper portion of than engine apart anyways, I recommend you replace the EGR cooler as well. Usually if one's gone, the other ain't too far behind.

that 2003 has the round cooler there the good ones probably ok
I drove my truck for a year with a 25-30 spread put a coolant filter on it and cleaned the system out before I put a new oil cooler in
be careful a poped oil cooler is a big mess

Since you are going in there, update the STC, clean your intake, update the fuel regulator, drill out or buy bigger fuel banjos. I drilled mine out because it was cheaper and i drilled holes bigger than what you get with the 6.4 banjo.

It does not buy you any time. You do not want the oil cooler to explode either. Oil in the cooling system has to be cleaned out and you would have the added joy of replacing every rubber hose under the hood the coolant runs through.

I'll definately replace it. Now the question is, is it worth spending a little extra for an aftermarket oil cooler or are the new ford oil coolers just as good? I don't think I'd trust a rebuild kit.
