I do not know if it is due to the modified EGR system.
Supposedly on later models improved heads were installed. But the high mileage engines that ran untouched were all in 03 models.
My personal 2006 got new headgaskets with ~35K

The 20mm heads were not installed until mid 2006. There are examples of all years with long miles. But I've seen the trend, too, of failed EGR coolers then after some mileage, failed head gaskets.

It's threads like this that make me think that going with a long block built right as a replacement for my '06 is a solid choice.
It's been parked for a few months now, after a catastrophic lifter failure. I think of a good build as a reset of sorts. Pretty much a new truck that I will know 100% of what's in it and how it is maintained from mile/hour zero.
The knowledge and willingness to help each other within this forum is hard to beat too.

Do you know your engine or truck manufacture date? If not, how about the injector hold down Torx size?
Also - did you ever have issues with your oil cooler, or have excessive heat?

I missed this post until this morning when I was reviewing this thread again. It's a good point. I've often wondered if owners might have a small leak for some time before they notice it, and during that time there is coolant getting into the combustion chambers and raising the pressure. The EGR cooler is something I would replace ASAP if I acquired the '04.5+ engine design, not wait until the coolant loss was easily noticed. I'm not sure where the tipping point would be, but that's not an experiment I would care to undertake.

Mark,
Date on the door jamb is June of '05. This seems to check out with a May 1, 2005 date on my FICM.
My injector hold downs are Torx 40 (old style with 1838 and 901C4 marking on top).
As for temps, oil temp seemed to hang out around 205-210 all the time. coolant temp never much more than 190. My difference in temps always 15+. I didn't realize this until I started using TorquePro and watching!
Pretty sure the EGR cooler and probably oil cooler as well are not OEM. My plan was to make it a few months longer at which time I would have done injectors, O-ring heads, studs, oil and EGR coolers, a turbo refresh (or replacement). In other words, address the usual suspects since there were about 170K that I didn't know how it had been ran or maintained.

Depends on your definition of bulletproofing. We definitely had parts that were issues that needed upgrading (ie bulletproofing).
04.5+ EGR coolers
Ford Gold coolant
Fuel pressure regulator spring
03-04 HPOP
04.5+ dummy plugs and standpipes
05+ STC fittings
FICMs
Just to name a few.
