2022 7.3 with engine noise

I've got an E450 with 80k that has an interesting engine noise.  If this was an LS engine I'd say it was a frozen lifter roller.  It sounds pretty similar to a belt squeak.  It's pretty audible with a stethoscope in the right exhaust manifold.  

Are cam/lifter problems common on these?

I just finished one last week. It had the exact same sound. The truck was a 2021 with over 100,000 miles 12 months old construction truck runs all the time.  One camshaft lobe was worn pitted (looked like an old bearing) and the roller lifter did not spin right could get to spots where it would not turn. Customer said it just started. 

Replaced cam and lifters that fixed it.

 

(A few were reported on hotline past reports.)

Thanks for the reply!  That sure is what it sounds like.  It's coming apart soon.  Thankfully it's not me that's going to do it.  Vans are miserable.  Ambulances are even more miserable.

I wanted to follow up with the final outcome.  See the attached lifter pic.  It needs a cam and lifter.  Cylinder has a bit of a scuff in it, so customer is deciding if they want an engine instead.

Interestingly, last week I visited a fleet of ambulances that runs a fleet of units with this engine.  They have maybe 200 in all.  They see lots of idle time because they are stationed at various points around the County with crews in them.  They said they've had about 30 cam/lifter failures just like this one.   They had a few of them stacked on a bench.
