I have seen some 09 and 10 dodge challenger 5.7 hemis breaking there timing chains on some other forums. Anyone have that happen with there hemi on here? Seems like it is only affecting mds engines such as the auto trans challengers. The 6 speeds are non mds.
Dodge challengers breaking timing chains

I don't understand how the chains can break, unless they're just horribly engineered. I know they do stretch a bit over time...
Does anyone know for sure if it is a belt or a chain?
I thought so. It's puzzling why this could occur.
Chain. Probably a "Hy-Vo" Chain, not a Roller Chain, but not sure. Don't know what the new name for Hy-Vo chain is, but it is the one that looks like this vvvvvvvvvvvvv, but the Roller Chain like like this oooooooooooooo, like a bicycle chain. I think they may not call Hy-Vo chain "Silent" endless chain.

I'm not sure what's up w/the Challenger chains, but this sorta thing can certainly happen. The good news is that you're less likely to need dental work when your car's timing chain bites it!

It's probably just like any configuration of cam drive. It's almost never the belt or chain itself, it's another associated component causing the system to fail. Bad idler, tensioner, guide, etc.

Search the Traverse/Acadia/Enclave forums, or anything with the 3.6L. They're having timing chain problems too.

There are a few engines notorious for chain problem, and not all the chains came from China.
Some came from the USA:
Ford modular V8
Ford Cologne V6
Chevy Caviler OHV
In Germany the 15 degree VW VR6 has plenty of chain failures
The Mitsubishi 4B11T has chain problems during some years, I don't know if related GEMA engines do too.

so how was the car driven?
Remember the exact same engine is used across the entire line of V8 cars and trucks.
IMO it appears to be far less than 20 folks involved. A whole lot of "Internet Amplification".
Chrysler has a complicated VVT setup moving the cam that is in the drive sprocket, I'm sure that has something to do with this. But it may be a quality control issue with a bad part or it may just be a programming issue fixed with a PCM flash.

Considering the number of pieces in the assembly of a roller chain, I'm surprised we don't hear of more problems than we do. Ed
Aah, the PCM reflash that will stop it from going in MDS as often
