I have 165k miles on my 6.0 psd with basically a EGR valve replacement and/or cleaning every 80k miles and that's about it. Best truck I've owned to date.
Alot of the EMS truck riggers caused alot of the early 6.0 problems by simply using the incorrect antifreeze and wire harnesses that were routed incorrectly that developed chafed wires causing many of these early problems. It didn't help that Ford's techs weren't trained properly to rectify these problems as well.
