First clue to the problem
I have a 2005 E350 van with the 6.0. I purchased it with 127000 miles and put about 2000 miles on it. While it was idling in my yard, something occured and it started running rough and emitting white smoke. Using Forscan, I could turn off injectors and found cylinder 8 seemed to be the problem. I purchased an adapter to check compression but can't get it to fit into the glow plug hole due to lack of clearance. I installed a new injector and found the original lower o ring was degraded and probably leaking. New injector made no difference. I've decided to pull the engine. Last night I got the intake manifold off and found this on cylinder 8:[.com/user/mharneyva/media/IMG_20170215_214936535_zpssxf09h3o.jpg.html]

One of the intake valve sides has erosion on one side. That's not debris, but damaged fiberglass gasket frame material.
What happened?
BTW, it fails the smooth crank test. When I spin the motor with the starter it's not even; speeding up for about 1 cylinders worth of revolution.

I would recognize speeding up for one cylinder on smooth crank test is indicating no-compression in the cylinder.

Degas bottle was full. I dont know if the exhaust smelled of coolant. I have a CTS Edge engine monitor with EGT and had no suspicious readings to my newly trained eye in the couple of thousand miles I drove it.

That piston needs to be replaced. You could rebuild or use Ashville Engines and transfer your stuff over to the new block.

It looks to me something got in that cylinder and bounced around (indicator B) and interfered with that valve that appears bent (indicator A). I'm pretty sure I can see daylight past that valve seat.
So what was happening since you have a bent valve that is not seating it will not hold compression, resulting in no combustion of the injected fuel. That's why it smoked and is wet with fuel.

Earlier inspection of the turbo looked alright. I'll check again.
No sign of foreign object damage in the intake manifold or head air inlets.
I think chunks of the piston did all the impact damage.
There are signs of fuel getting by injector 8's lower o-ring.
So it had been overfueling for awhile, probably before I got it. I installed the fuel blue spring update. Overfueling gets worse, and the piston eventually begins to disintegrate. This prangs the intake valve ending anymore compression.
Fortunately it occured while idling in the driveway at home.

It looks very similar to what happened to mine with foreign object damage. I had a bolt/nut get dropped into the intake during oil cooler repair. About 250 miles later it dropped into the cylinder, bent the valve, beat the daylights out of the piston, bent the glow plug, then exited with no more damage. It did not damage the head, probably due to the generous carbon layer. The piston, connecting rod, valve, glow plug, injector, etc. were replaced and it is running nicely. Dealer did all the work and tossed in new HG's and ARP studs for both sides to make me happy.
Your other scenario is possible too, though I found our piston to be pretty tough. It looks like something got in yours. Things can sit in the intake for a while before moving on. Mine survived about five minutes of torture before the object was ejected. Never did find it. It sounded like dwarves with hammers under the hood though.
Note: Whenever you have the intakes exposed, do what Diesel Tech Ron always cautioned, put tape over them and clean the area well!

Thanks!
After seeing the damage, I was looking at options and saw there is a local Powerstroke remanufacturer in town. Great! Blackwater Engines. After looking them up, I was looking for other options.
I'll check out Ashville.

Check the glow plug on that cylinder. If the previous owner cycled the key several times before starting, he could have melted the tip off and that caused the damage. A member here, TooManyToys has had that happen.
