Heard back from the dealership, and they concur that it's the turbo that died. Fortunately, it's still under warranty, so it won't cost me anything, but it'll take 7-10 days for them to get a new part, so I'm without a truck for at least a week, more likely two. They're working on getting me a loaner, but that might not happen until next Monday, depending on when one gets returned.
Glad they’re taking care of you. Still having trouble with the fact that you drove it that far with a “dead” turbo. I too am anxious to hear just exactly what failed and hope they’re not just throwing parts at it. Sorry if I sound skeptical but my background is sales and servicing of turbos for the last decade or two.

The fact that these Turbochargers have an Electronic Waste Gate I'm sure that is where the problem is. Personally I prefer the old school vacuum/pressure waste gates as they work very well!

Yeah, that was my first thought that the waste gate was stuck open . But why the audible clunk and then loss of power ?. Maybe the actuator constantly trying to close it ? Codes would probably tell us everything but alas.

Do remember that it has a potentiometer in there. This makes the waste gates a bit precise for electric control. If there becomes a small open in that potentiometer then the turbocharger will end up failing

"Dead" is my word, not theirs, and I admit that I'm no mechanic, so I'm probably getting the details wrong. Perhaps I should just have said that they agreed that the turbo is where the problem lies. I'm hoping to get a few more details tomorrow, and will share them; I welcome feedback from more knowledgeable minds than mine.

Did they give any more details? Was just a bad unit, bad blow off valve, or oil starvation or anything like that?
I just talked with the dealership, and oil starvation was the major issue. They got a new turbo in today, so I might even have the truck back by Monday; aside from installing the new unit, they're going to check all of the lines and see if they can figure out why the oil wasn't getting through. Apparently some propellers inside the unit were also a little chewed up, but we don't know if that was a cause or an effect of the situation; they're going to send my bad unit back to Ford so that they can dissect it and see if it was a one-off or a larger problem, but I doubt that I'll hear anything about that unless it becomes a major recall.

From what you are telling my I do have a thought as to what could have happened and it is considered common for Turbocharged Engines. What I'm figuring is the oil may have gotten hot enough under load(towing or heavy throttle) and then shut off right away without letting the Engine idle for a minute or two to let the oil cool.down a bit. This will cause the oil in the Turbocharger to build up in the shaft. Let that do it long enough and a failure like what you just had can certainly cause that. That said I know the Engine Coolant going through the Turbocharger is supposed to help mitigate that be letting the coolant col the Turbocharger vs the old days where it was just Oil that ran through.

That could be possible. I don't tow very much, but I do have a bit of a lead foot, and this did happen while I was trying to overtake someone through a mountain pass, so it's possible that the combination of those three factors led to the build-up that you mentioned and just overwhelmed the system at that moment. Hopefully, I'll get a few more details once they've completed the swap, and I'll have more of an idea.

Makes sense now. Probably just seized the turbine shaft to the bearings thus stopping rotation and the no boost. Also kept it from a rapid unscheduled disassembly which would have much messier. They should just replace the oil feed line as a precaution. They can inspect it but I would tell them not to reuse it . I think Chris is on to something with it being coked up and finally seized up. Thanks for sharing the findings.

I appreciate everyone's feedback, and if my experience can be helpful to someone else, then it's worth sharing as much detail as possible. It's both the least and most that I can really do to be of help to everyone else on here.

One other scenario could be that the oil feed line( screen )plugged and starved the turbo for oil. That would also mean that it couldn’t pump oil out the exhaust after failure which would explain your oil level maintaining proper level and no smoke out the exhaust.

Picking up the truck today, and here's the report on what was done.

Thanks, everyone, for your feedback.
New oil feed pipe ? doesn’t say if old was plugged/restricted but betting it was. Thanks for sharing the info!

And the oil feed screen too. ( JT4Z-6C683-A) ?
