I haven't seen this mentioned. What about the variable cam timing on the auto? That's hooked directly to the gear and the chain and could cause all kinds of problems, and it would explain why it's happening to the autos. I believe this is a British made part and I would like to know have they had any problems before or am I just barking up the wrong tree?

oh **** Landy's 484 cube hemi with a broken timing chain, not much of anything else
I've done that, and searched using all sorts of combinations, and I'm coming up with nothing much either.

I'm a numbers guy too, and I have to honestly think that this issue is not a huge failure problem, like huge in that most or all Hemi's will eventually fail, or some high percentage rate will fail.

There's a lot of other Chrysler products other than the Challenger, that have the MDS system too, and are probably racking up more miles than the average Challenger owner. Failures of these others just don't seem to be showing up on the net.........for whatever reason.

Does this make owners that have had the problem feel better? I'm sure not. I would be upset too, very upset.

I guess for me anyways, I feel that it may be more of an "isolated" type problem, and not an "inherent" problem with the MDS 5.7's.

Chain/tensioner assemblies that have every part in tolerance, with all part materials "in spec" , and correctly assembled, may not be failing. But, just one or two pieces of this assembly, out of tolerance or spec will fail in time.

I'm not a nervous wreck about this, but I hate to hear about forum members having this failure, and then wondering of the why, and possibly when, this could happen to me.

I just hope that Chrysler is keeping an eye on this, and counting the number of failures that are coming in. Time will tell as more folks rack up more miles.

I'm going to keep on driving with MDS as usual, enjoying the car, and what's going to happen, or not happen, will happen.

I'm heading out for a good cruise in a few minutes. Hope I don't hear a "pop" and then............................ LOL

Is this new? Only the autos come with Variable Cam Timing as far as I know.

Only the automatic cars have the MDS (cylinder shut down on 4 cylinders in easy cruise mode). Both automatic and manual cars have the variable cam timing.

My RT has been gutted. I now have pictures of my bent valves which they are going to replace. The heads are on the work bench awaiting new valves and head kit(this is on back order and they are checking with other dealers for availability). When I looked in the engine compartment it reminded me of the movie Se7en. Man-O-man. And she is sooooo dirty. Only one thing to do...listen to some Iron Maiden....should make me feel better.

P.S.
There was no "pop", no warning, just total engine failure.

"Z" is short for poser.

I know this doesn't happen to every Challenger with an automatic tranny, but reading about these failures makes me sick. In my opinion, a timing chain failure should not happen. It seems to me the chain is too weak for the MDS system and they should all be replaced. Something else is the resale value of a Challenger with an automatic vs. a six speed car. After reading this thread I know what direction I would go.

My car is totally stock, absolutely no modifications, except tinted windows. I don't think the tinted windows affected the timing chain, but I can't be 100% sure.
