I had a ticking noise. At first only at cold starts. Then it got worst. Took to dealer, the problem was broken bolts on exhaust manifold. $500 labor. $600 total

 

That's the first thing they usually check because the bolts are known to break on the Rams around 50k miles or so. The issue with mine was no that manifold but something more serious that they couldn't find. They ended up buying the truck back from me.

 

Following this thread cause I have the same problem. Hopefully someone with hands on experience with the timing tensioner and guides will see this and speak up. From what I've researched it seems whats happening is the timing chain guide/tensioner wear down to the point that it will drive fine on 8 cylinders but as soon as the timing adjusts to get into 4 cylinder mode (MDS) it gives the timing chain just enough slack to slap against something in there causing this rattle noise. As soon as I get my backup vehicle going I will be tearing my hemi apart to fiqure this out once and for all.

I dealt with this problem for four months last year. 2011 ram Five different visits to the dealership and ended up being the same as your 2009 issue. Lifter broken pushrod they replaced one head all of the M DS it fixed the problem temporarily. Problem is back 6 months later. Exact copy of the ticking you all are mentioning. Chrysler and especially the dealerships act like they've never heard of this problem. It's embarrassing to drive around town at slow speeds. Tow haul off does stop it.

 

I have a 2011 Hemi with the same issue. Several trips to dealer Replaced 1 head lifters broken push rod all MDSs fixed the problem for 6 months. Now it's back. I'm glad to see others are reporting this as last year nobody was recording issues. Time to head back to the dealer again.

 

Late to the party but wth...

This Hemi has the MDS tick subsequent to the damage (2012) depicted. It's not a timing chain issue! Chrysler (FCA) flipped me off just prior to the power train warranty expiration because... "It's normal." Horse puckies, it's normal.

 

Ok so since the nice weather has hit ( atleast in the Maritimes Canada ) . It's a pis off not being able to put window in truck cause of this noise. It was briefly mentioned above about Chrysler never hearing about this before. I'm in the same boat! When I reached Chrysler Canada they pretty much did what I already did, which was notify the dealer. So really no help at all other than the case being recorded. After almost three years I still have this issue and can't fathom for the life of me that if anyone from the dealer or Chrysler itself had my truck they would think this is reasonable . Question! Has everyone here sarted a case or pitched a call to chrysler? Cause I'm starting to think they know of a lot more complaints than they are letting on about. Like any recall this has to be sorted. I
Love this forum! It's helpful and I guess in a way nice to see im not alone! But it's not right for us to pay X amount of dollars and warranty and get that type service and answers regarding this issues. This obviously seems to be on both sides of the border within Canada and the U.S. So have we all put in a work ticket? Complaint? To Chrysler? I'm calling again and having numbers may go a different route with guys. This time there better not be any " never heard of it before" thanks everyone.

 

Good pictures. Based on the imbedded marks (possibly from a screw or bolt or a piston fragment) it looks to me that something got into the combustion chamber causing the damage. So I'm not sure this was even related to the MDS noise, much less proving or disproving a loose timing chain theory.


How many miles were on this motor?

I believe Chrysler is aware but also believe at least as of the fall of 2014 do not know how to completely resolve this problem.
After my fiasco last summer which include about 3 months of pushing the dealer and many many parts thrown at it because they didn't know how to resolve the problem. Ill be going to the dealer again next Monday to see what they say this time. Chrysler was involved last summer and the case was closed in the fall but only after I got an extended warranty from them paid for by them because I had a feeling the problem was not fixed and the issue would come back, as it did. I called Chrysler again before I called the dealer to ensure we don't start over from scratch. Now my info is linked to the issues I had last fall. Ticking.
Will keep you all posted.

 

55K km. Damage was caused by a screw with 10mm head - similar to the one used to fasten the TB to the manifold. Theory (dealer's) was that the screw was somehow left in the intake manifold during manufacture. The screw had been in there for some time - the inner walls of the plenum were scored up bad. The engine was purring like a kitten when I approached the dealer about an oil leak on the intake near the PCV valve housing. Shortly thereafter, the internal damage was discovered. MDS ticking began shortly after this repair. It took me over a year to get somebody at the dealer to acknowledge that. They agreed that it was not right. Chrysler engineering disagreed.
