|crow||It is a recall, not a TSB.|
|10-16-2014 09:39 PM|
I had my work done to my 2011 RT at the dealer this week. I asked them afterward about the oil, since i run synthetic and they said they did not replace the oil or filter. They may have drained it and refilled. It looked semi-dark so i dont think its new oil. The car runs nice and quiet, seems to have much less engine tick/noise then before. I have 43k miles on my car.
I am confused as to why this is not a recall, but a TSB. Seems to me its more of a safety issue if your engine goes at highway speeds. I did not even know about this TSB until i took my car in for the air bag wiring harness recall. Chrysler had been sending me letters and called me several times about the wiring harness recall but never mentioned the timing chain TSB. It was the dealer that saw it on the computer and told me i should do it when i brought the car in for the airbag harness recall.

I've got a little over 10k on my P01 service. No noises, no problems.
Car runs as good as ever, and I don't even think about this "issue" anymore.

Mileage on new parts
I now have 13,688 miles on mine since my failure on 11/13/13. I drive about 28 miles round trip each day on interstate at 68 to 75 mphs almost always with MDS engaged since the repair. It's been to St Louis for a Cards game and back in June, over 1,000 miles roundtrip, again with no problems. I have noticed absolutely none of the problem noises from under the hood that had been occurring for over 10 months before mine failed. I don't plan on "running it with MDS disengaged" so if mine fails again with the aluminum guide and all the other new parts (2 new heads, 16 new pushrods, etc., etc.) I'll be very disappointed!! And believe me, Pietro and Jill will be the first to hear about it. Recall they both assured me there was "nothing to worry about" back in August 2013!!

|salvy59||I guess it seems right what you are saying after all the original guide part had to break for the chain to jump!|

The nylon material gets slick(er) in the presence of oil (the TC system gets oil all over chain, guides, etc inside the timing cover)
The chain runs from the top (thicker portion) to bottom (toward narrow portion), there's an overhang on the nylon part - the tabs are there for assembly onto the metal base part.
Here's what the guide looks like - the material is ~ 3/8"thick and installed on engine (engine runs CW viewed from front):

|salvy59||How thick is the nylon part on the aluminum guide? is it thick enough where if the nylon top piece breaks on the guide the chain could jump a tooth and still destroy the engine?|

I find it difficult to believe an aluminum guide could have failed. Most every mfgr. that has timing chain guides use that type of construction.
A remote possibility is the tensioner failing (those are still all (black) plastic parts)...if that part went south, all kinds of things would go wrong then...

|72/340||What with failures well hashed out and recalls being done, let's see how the replacements are holding up. Post up your milage on the new TC. Mine failed at 42k, the replacement went to 26k before I got the recall, all parts looked fine at that time. Coming up on 6k on the newest TC...|
