I have a 99 F350, and just turned it over 142000. I bought it because the
experience of my family members with them over the past 10-12 years. My
brother-in-law, a diesel mechanic, has told me 400k miles is not out of
the question. Main thing is regular oil changes, with filter changes with
a good quality oil, and do not let them get hot. We use Rotella, and use
a mobile 601 filter (made for synthetic oils, smaller particle
filtering). He has mentioned nothing of burnt valves. Does recommend
getting the head gaskets replaced around 250k -300k as a preventative, as
he has seen a few blow head gaskets at around 300k, resulting in
overheating. On another note, he said the chrome rings will wear until
around 300K, after which you may see some wear on the cylinders, but it
will keep running well beyond that.
You did the right thing though, asking the guys who own one.
