Since I have no intensions of going toe to toe with you ricohman and you appear to have more inside info than anyone else on the thread I would recommend that you save yourself and unload your 2015 while it still has some value. If i have to eat my words I will be more than happy to come back and apologize to you.

Heck, my 04 6.0 is the best truck I ever had. I just hope I get as good of service on my new 6.7.

The floodgates have opened wide.The things are coming apart.
Anyway the dealer has a sea of them in the lot now. There is absolutely nothing sound about the 6.7.
When I see a crank that has the mass of the average 80 hp. Diesel, it's a problem. Cranks are snapping, no surprise. This lightweight crank will want to spin up faster, a partial byproduct of the horsepower wars directed at 20yr to 40 yr. old market segment.
I see a main and rod bearings with no locking tang, it is a problem. The 6.7 is spinning bearings.
The spindly connecting rods have seemed to hold up well. I was a bit off on the outcome of using a rod that size.
Turbo issues on the early boys was an easy fix but this major stuff is not.
The point is the the catastrophic failures are piling up. We are well beyond whether or not the 6.7 has inherent problems are now manifesting themselves, they do and are.
Bottom line is, somewhere between CAD, the manufacturing in China and the installation in Mexico, there is a very real problem, that is sometimes occurring.
The only time I have used the word mass, is when I have stated the 6.7 crank is lacking enough mass for that engine and there are cranks snapping.
hose of you going through this horrible process of having valves stick and have pistons slam into them and then go through down time while your truck gets eviserated and if for some reason you don't think you should have to take it any more, check your state's lemon law. Get all of your money back. Ide go further but that's me.
This cracking and temporarily seizing valves in their guides is occurring during regeneration process creating heat the valves just cannot handle, just rolling down the road.
It was a gamble setting it up that way to avoid the expense of components, a 9th injector creating the nessasary heat away from the combustion chamber.
And please, anybody attempting a ream, that's fine as frog's hair and all but you better had do it right OR you will create a high end skip/ shake that will be there constantly. The valve will try cocking to the side and not seal properly at mid to high rpms, if you take to much off the guide walls.
It is a pretty fine line opening it up enough to allow for thermal expansion and a normal amount of stem film and not creating a guide that will create the condition that I just mentioned above.
Keep researching and if you can swing the possibilities along with definites like your turbo a WILL blow and it will send trash into your motor go ahead.
I'm not saying you will go thru the wringer but you had better be prepared to. Oh, this boy can leave you stranded.
And on and on it goes....
Makes me think we all got hornswoggled!

I've seen DieselNick's posts over there.......he's either a troll or just really off the reservation. Major drama queen, that's for sure.
Remember, just because somebody is a mechanic(or says they are) doesn't meant they are a good mechanic.

There is a guy called dieselnick or something like that on the diesel stop forums.
He says he has seen massive amounts of crankshaft, bearing and rod failures. Cranks are snapping in half on a regular basis. Front crankcase cover are busting, heads are cracking, injectors are flying out, valves are hitting the pistons.
He says the flood gates are wide open now and Ford lots are filling with busted unservicable trucks. Soon there will be massive recalls for this dangerous engine.
He also advises nobody should ever own such a thing.
