I think we need to be cautious to not become paranoid or needlessly have it affect our world when people post horror stories about similar engines or vehicles as the ones we own. Sure, we feel empathy for their plight, but remember, 80% of folks who post on these sites, only post negative comments. (Just look at the list of subjects) It's human nature to lean negative, but are not indicative of any issues you'll ever see.

If any of you guys remember, Johnny Langton had a valvetrain-related failure before he passed. He caught it before it caused lower engine damage.

We have a 2012 V10 F-450 at work with 28k on it. So far it's been nothing but perfect. Very odd being only 2013 trucks. I have not received any info back from the contacts I inquired to about their failures yet. But I know they(various fleets) have a ton of 2011-2016 V10s.

Just another quick note and reminder... These are high Idle time units... some have over 3000 engine hours on them already. But once again, not this kind of failure rates in the 2011's, under the exact same working conditions.

Makes me really wonder about oil pump, pickup, sump, and filter potential changes.

My v10 company truck has mid 5k hours on it with no problems, but it is a 2011. There is a 2014 in my work group, but no problems with it as of yet.

And is it just the camera or maybe just me but are some of the other follower bearings bluish like they were hot?

I did some searching and it appears that that is exactly what it is and if the seal is compromised oil pressure to the cam and associated parts will be compromised.
Is this the common find on the engines????
Edit, I meant on Fleetguy48138's truck Engine problems...

This is what I'm thinking too after seeing that tensioner seal, unless it was damaged on removal. I wonder where the roller on that rocker arm went.

looking at the pics, here is my latest theory.
- 90% of failures have been on the right side of the motor (end of the oil system).
- These are high idle time (1200 rpm) units, which are already operating at the lower thresholds of oil pressure
- Timing chain tensioner on that right side is leaking (end of the line).
- This is causing a lack of lubrication, thus failure of the valve train, and if not caught in time, Catastrophic engine failure.
