This reminds me of the timing chain guide problem (and breaking timing chains) that affected the '09 - '13 and some '14 5.7 & A5 engines in Challengers.
There was a filing made with NHTSA about the incidences of this, citing that chains could break down on the road, creating a safety hazard.
FCA took notice and came out with a service campaign.
So for there's not been that many instances - I recall about 3 - 4 (to date) on the forum. They've involved 6.1 SRT engines and the 392 / 6.4 SRT engine as well.
The needle bearings in the roller lifter appear the failure item. This lifter is used on 5.7 / 6.1 / 6.4 engines (same part #). So its spanned multiple years.
There may have been bad batches from the supplier - there's millions on these engines (Jeeps and Ram trucks use the 5.7 and the 6.4 BGE) and I've heard of this occurring at times on high mileage Rams, but more the exception than typical...[Eberspacher is the supplier of the lifters...]
With the 392 engine being more recent in production, I don't if its a matter of time when they get more miles on them and if this turns up more frequently.
If more claims turn up, FCA might take action on this.
