I dis-abled the MDS on my 2010 with a predator, sounds better. Should everyone just do a timing chain change at 30,000 miles as preventative maintenance? Is there an aftermarket timing change that would eliminate this issue? Seems like Dodge would eventually do a TSB on a recommended timing change interval when they have conclusive evidence that the current timing change is a weak link. What are owenrs thoughts on this impending issue? I have an auto and a 6 speed, is it a factor on the 6 speedds also?
That sounds like a good pro-active strategy, even if it is just replacing with a new chain that is the same model. The cherry on top is if there was a designated "specialist" amongst our community who everybody could send their intact old chain to (with appropriate documentation to record the details of its history). If there are consistent wear patterns (or micro-crack fatigues as was described in an earlier post) that are unique to installations on the auto Challengers (as opposed to a typical, high mileage chain from a Hemi in the stick or any other Hemi Dodge models, altogether), that would be an important piece of the puzzle.
An additional perk (not that anyone should hope for this scenario) is if they replace the chain, and something still
breaks in that area (like the tensioner), that would be important to know, as well.
There's probably enough info before us right now for Dodge to officially specify some highly-recommended pro-active measures...like a tensioner mechanism inspection
at 30k? If high wear is noted, a new one should be installed. I'm guessing that still requires tearing off a bunch of stuff to get to, from being just a casual preventative inspection procedure? Anybody know more about such a process?...degree of labor and cost?
