Has anyone heard of any issues with the 2015 6.7L Power Strokes having main bearing problems? I have a 2015 F-250 with 29,996 miles on it, took it in for an oil change and they discovered metal shavings in the oil pan. They pulled the pan off and discovered two of the main bearings had come apart.

Just wondering if anyone else has seen anything like this.

By the way....new short block is on the way!

 

Never heard of this, but it is possible.
Anyone else?

 

Never heard of it.

Did it run okay? Make any noise? Two main bearings torn up is pretty strange with no symptoms.

 

No noise, was running great....even got better mileage than I had been getting. Just took it in for an oil change.

 

Ford uses tangless bearings in the 6.7l. The clamping force of the caps keeps the bearings in place as I understand it. Maybe Keith will chime in and give us more info on this.

but in mean time you can go to this link and view the cookbooks for the 6.7l and see the internals of the engines. There is an update that list differences between 2011-2014 and the 2015 up 6.7's

Hadn't heard of this issue either.

 

Well, now you get a new engine, that's cool.

 

The techs didn't have any input as to what may have caused it? New engine or not, that is far from ok in my book. I hope they do a stand up job for you.

 

I see that the 2015 and up, has an IROX polymer coating on the main bearings. I wonder if plastic bearings are a bad idea.

 

Wow...that's not something I've heard of either.

Can you post a picture or two?

 

I have heard of it but the engines I saw with the bottom end coming apart had maintenance issues. A lot of municipal and city fleet trucks unfortunately are not serviced correctly and oil changes can occur every year or two... with no regard for engine hours. Another failure I dealt with was a remanufactured engine that spun most of the mains for no apparent reason... at least I could not explain the failure.

There are several discussions on the DTS website about spun bearings and reports of this failure happening. The tang-less design requires the proper amount of bearing crush to keep them in place... apparently it does not always go to plan. So, YES, this is not an unheard of failure but it is not wide spread so lets not panic. We need to remember that bearing failures can be induced by lack of maintenance, improper oil, contaminated engine oil whether it be fuel dilution or coolant contamination. We need to be reminded that when the turbocharger is removed from a 6.7L coolant always drains out of the return passage and spills into the crankcase. Cannot be avoided. It is absolutely necessary to change the engine oil and filter when servicing the turbocharger BEFORE starting the engine. Here is that the workshop manual procedure states at the very beginning of the procedure: That is all I have to say about that.

 

I don't think anyone is "panicking", but catastrophic engine failure isn't something to take lightly. Thanks for your input.

 

No, not yet. LMAO! Anyone (like yourself) who has spent significant time on public forums knows how one post regardless of it's accuracy or intent can go viral and get people whipped up in a frenzy. I could cite several topics right here on FTE alone that immediately come to mind but... we need to stay on topic here.

 

I'd bet money that a high number of 6.7 that had turbo work are sent out as repaired without that "post-op" oil change.

 

Tangless bearings... WTH were they thinking?
