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............................
