Exclamation Disturbing Hemi Catastrophic Failure Rumor

As most of you already know, I am a Ram, Dodge, Chrysler, Jeep tech at a dealership. Occassionally, we talk to Chrysler technical support and hear a few rumors about upcoming recalls, bullitens, and things that just happen.

The other day a coworker was speaking to a tech rep and it seems that some of the newer Hemi engines have a problem with the timing chain guide/tensioner assembly and it's causing the chain to fail in some fashion and evidently it's causing catastrophic engine failure (valves and pistons coming together at high speed).

Now, when asked what "newer" meant, the rep says it is unclear at what point these guide assemblies were installed but he did say that the part is a redesign that was intended to save money. Looks like that's going to backfire.

As of this point, it is also unclear what will be done to identify affected vehicles and what will be done to remedy the problem. I don't know if this is a problem limited to the 5.7 engines or if the 6.4 is also included. I will keep an eye out for more info on this matter and post anything I find. Keep in mind that though the source is a Chryslelr tech rep, it's still just a rumor at this point and I have yet to see this failure for myself.
