2011 6.7L motor trashed
My 13 yr old motor had 104,000 miles. Shop thinks it was main bearing failure as the oil filter was full of shiny metal shavings. Oil & filters were changed religiously. Anyone else have this issue?????????

Not personally but changing oil and filters doesn't 100% guarantee long life, especially if the motor was worked hard or abused in other ways. Sometimes parts just fail because they had undetected issues from the get-go.
Do NOT let them put a Jasper motor in it. You'll regret it in about 13k miles. Go with a rebuild junkyard motor, go with a Ford replacement, or go with US Engine Production - any of these are going to be better than a Jasper.

If the main bearings are toast, and I'm not ready to definitively say that they are, you wouldn't be the only one. It is not a big enough problem that ever forced Fords hand to recall or correct, but it is definitely enough of a problem that you can read about it on the internets; forum posts that start just like yours.

It died on the hwy. oil light first, then battery. And stopped running.

Yeah, had two 6.7L go that route around the 100k mark. Two 2016 F250's used as Forman's Transportaion. Factory stock with hardly any towing. One just quit going down the road and the other locked up and threw a rod. Bearings were shot in both. They were out of warranty, so I did the replacement work and tore down the cores before sending them back. Needless to say we haven't been all that trusting of the 6.7L Powerstroke and have not purchased one since the second engine failure.

I’m not saying they’re the greatest available, but I’ve installed Jasper remans for customers since about 2017, and so far they’re proving to be dependable in the time that they’ve returned for regular maintenance. 3 were GM LS small blocks and 1 was a Ford 6.8 in a 2010 F350.
So I just wondered why your experience with them wasn’t the same.

Here's a good way to put it, I guess.. There are a myriad of reasons that I wouldn't own any new diesel, and this thread Illumiates one of many reasons.

How often was the oil changed? When the truck told you to? Or at a specific interval?
If a specific interval? What was the interval?
What weight of oil was used?
10W30? Or 5w40?

My opinion
the ford 6.7 prior to 2023 suffers from fuel dilution from regens
at the same time…the ccv sends oil foam vapors into the intake
as a result
you do not know how diluted your oil is and at what point are you running on super thin oil
there are many 6.7 engine failures not a high percent…but they are out there. At one point last year ford had a 500+ back order for engines to repair failed engines.
time will tell if things get better for the 2023 and later. A switch was made in the regen process to use a ninth injector which would eliminate regen related fuel dilution of oil. Why do you think ford made this change if it wasnt a serious problem.
me personally i dont care what my OLM says, my oil gets changed every 2500 to 3000 miles and there is always more oil coming out than what i put in due to fuel dilution.
in other words.you did nothing wrong…this is a ford design problem.

Well said and it what I was eluding to. I never ever go by the oil life monitor. On my 7.3 and 6.0, it gets changed at 5000 miles. I would recommend the same for a 6.7 if not every 4000 like speakerfritz.
I also DO NOT recommend the 10w30 Ford says to run in these engines. Seems too thin for a diesel. I've made most of my 6.7 customers switch to 5w40. Especially the ones who tow and work their truck.

150 hours and 15w-40.

The 15w40 helps but between the fuel dilution and long interval, I don't see it helping.

I have taken the time to test oil across my fleet many times before settling in on the 150 hour interval for trucks. My equipment living a much more strenuous life of half to full throttle operation gets by with 300 hour change intervals. Just a bad luck run of engines is all I can conclude as ive got one 6.7L left in the fleet and its in an F750 dump just a hair shy of 200k now and no issues.
