I do frequent powerstroke.org for advice and research purposes.
I just had my EGR cooler and oil cooler replaced under warranty and I'm having the same problem again. I'm taking it in next Tuesday to another local shop for diagnosis. I hope it not the heads or headgaskets.

Do you have a coolant filter?
There appears to be a ton of stuff, like block casting sand, floating around in the coolant system.
This debris plugs up the oil cooler which causes no coolant flow to the EGR cooler and the Egr cooler breaks due to the excessive heat. The oil cooler/Egr cooler are in series.
Put on a coolant filter. Dieselsite.com sells them.
Make sure you use the Ford coolant or (Zerex G-05) only. If you mix coolants it will cause an emulsion.
That's what bothers me about the 6.0L. I did my research and homework when I bought mine used. I figured most of the problems with the 6.0L where worked out by 06 and 07. When I bought it in November it had 84k miles mostly highway miles pulling a small enclosed tool trailer.
The 6.0L shouldn't need a coolant filter to prevent EGR problems. I've contemplated getting one.
The 6.0L shouldn't need a bypass filter to filter the oil better. The full flow filter should do that. I've contemplated getting one of those too.
I've decided to NOT buy either one b/c the truck should have been made to NOT need those things to properly last. I'll continue to use MC oil, MC or OEM oil and fuel filters and if it doesn't make it, oh well. Shame on Ford for continuing the relationship with Navistar who made those motors.
When my EGR was replaced, they re-filled with Motorcraft Premium Gold. And yes, Zerex G-05 is an OK substitute.
