No debris in the solenoids. They look brand new.

Just the Motorcraft specified oil filter. No extended intervals... 5k miles at most. Wasted a lot of money on oil.
5K OCI.
WOW Less extreme? Crank friggen broke and butcher mech was in there previously. Rings were bound up and pistons were NASTY and loaded like a full diaper.
Your engine is super clean, but yeah, you could have used other oils. I do wonder how your secondary rings are (see video).....that said new engine parts going to be cha-ching as well.
Our new van will have same engine, ala 2025. Man I hope improved version!
Yikes heads are 1600 each, cams a couple hundred each plus all the extras.... seems like you're halfway to an engine... assuming they are available.
Wonder if a good machine shop could line hone the cam journals

That's why I looked at it too, to know what you had.
The top end damage. I knew there was carnage below but didn't expect the broken crank until he started removing the oil pump lol.
Yeah, I am already $2K in parts, then new heads and cams are probably an additional $3.5k. A new long block is $7K. I am still exploring my options.
The Ford rep crushed me like a bug. He said, we understand your concern and value you as a customer, but we can't help.
Honestly, find the cause first, or be prepared to spend twice. Either it suffered from no oil, very thin oil (fuel or water) or it lunched some debris at some point. If it was just a poorly hardened cam, the journals should still be perfect.
Are you doing the oil pump also? I have heard the Melling HV ones is the bees knees.
If in there, get the Melling if they have a match, that's a wear part.
Exactly. The clues are there. Possibly you had oil pressure and flow problems all along. Modern vehicles generally don't display oil pressure. Do you know what the oil pressure was?
The issues you describe and show are not common 3.5EB problems.
I am guessing that oil choice was not a factor here, and that something else was wrong. My company 2011 3.5EB had 160K hard miles on it when I retired. No issues what so ever.

Yup, the degree of damage has me thinking long block. Putting heads on it at this point, given the scope of the damage observed so far and the potential damage we don't know about, opens him up to wasting a ton of money and doing the job twice.
Slap a new cam and let it ride into the sunset?
friend has a small commercial construction business. he put 200k on one pulling a 10k trailer. it finally shot a rod out of the side of the block after living at 4k rpms all its life. they then started it up and drove it back to the shop like that.
A fellow f150 owner reached out to me. He had the phaser rattle, got it fixed. He developed the top end knock that I am having. The dealer found similar failure, but the lobes were gone and sent metal through the engine. They put a long block in his truck. Another Expedition owner had the same issue with cams.
So, I guess more cases will start to show up as these vehicles age.
Remember, this is the Gen 2 Ecoboost used from 2017 to 2020 (or 2021). The Gen 1 used bucket lifters.
