Sorry if I offended anyone.
I am sure there are some out there that haven't had problems , but all you have to do is google 6.0 Powerstroke and you will find lots of sites and posts with people talking about the problems they have had and how much money it will take to make a 6.0 dependable.
Steve_in_29 you even said in your very first post to have it bullet proofed.
That is not cheap if you do it right.
Yes I did but you can buy the 6.0 cheap now (they are 12 years old at the newest after all) and adding the cost of bulletproofing (if it wasn't already done) still gets you into the truck for a WAY less then buying something new. You also avoid the smog crap of newer trucks. Chevys and Dodges have their own issues with their trucks so nothing is perfect.
Yet there are a million+(?) of these in Super Duties with no issues and what another million(?) of the engines in school buses, etc, that have had no issues at all. The engine is a good engine, it was just stressed due to the TTY bolts and Ford adding another 100hp with their own tuning.
Also many owners simply didn't understand that unlike previous engines you couldn't neglect oil changes on the 6.0. Almost zero owners knew that until recently the ONLY oil that met Ford's requirement was the older "CJ" standard. I just saw a promo for the new 3rd Gen 6.7 (2020) and the engine's oil fill cap was still marked "CJ" and not the newer "CK". For Ford diesel use the oil has to state it meets Ford's "WSS-M2C171-F1" spec. There might be others but afaik only the newest Rotella CK formulations do and have it on the label.
Also there are issues with aftermarket oil filters. Originally every brand of filter for the 6.0 was made in the same plant in Germany. However at some point Ford started enforcing it's patent and the after market had to make varying changes to their filter for the 6.0. Some to the extent it required a replacement (taller) cap for the filter housing. That an unwitting buyer of a used truck might not be aware needed only that specific company's filter and installing anything else resulted in the bypass valve being constantly open.
Major Issues:
Harness chaffing - Pretty much unheard of in 05/06/07
Clogged oil coolers - Chemical flush and use CAT EC1 coolant with new cooler. A big part of the issues were caused by Ford going with their own coolant instead of the IH spec'ed type. If you insist on staying with Ford Gold then flush and refill about every 30-50K miles.
Failed EGR cooler - Pretty much taken care of by the coolant switch or a delete if you want.
Headgaskets - Some head gasket failures are now thought to have been due to Ford providing a radiator cap that wasn't up to the task (Ford redesigned it later). Install head studs, (reported failures after studding are usually due to the shop failing to prep the heads properly before instalation).
The only real mandatory "fix" should be properly installed head studs. As the causes behind the early 6.0 failures have been worked out it has been shown that you don't necessarily need the full on BP treatment. So I guess I should have been more specific.
