19johned53 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!

No - that wouldn't happen. There's plenty of travel in the tensioner to take up any slack.

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):

The design of the tensioner allows it to be pushed out well beyond the thickness of the nylon runner. All that would happen is the timing chain would run on the bare aluminum and probably make a lot of noise to warn you of the need for a new part.

It would beneficial to know if this was a car that had all the updated timing parts, specifically the aluminum/nylon guide shoe, or whether this was a screw up (early build '13) that had a engine built with the all -plastic white color (2nd revision) guide [these appear to be a late '11 through late '12 OEM part].

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...

My understanding is that it was resolved long ago too.
