Yeah i ordered parts on friday so far I will be replacing
-Camshaft phaser - # 53022243AF
-Timing chain - # 53022316AC
-Tensioner/Guide - #53022115AH
- Chain Guide - #04893429AA
- Mopar OEM oil pump #53021622BH
All parts are supposed to be upgraded with a more heavy duty material to prevent premature wear.
So far I'm down $280 for the timing component parts and $68 for the oil pump (not bad for a dealer ordered part imo) plus I'll have whatever the cost comes to for new antifreeze and oil change stuff. I paid $60 to ups for 3 day shipping so I could have all this done by Thursday and be able to use the truck to make the holiday road trip but now ups is saying I may not get everything til after Christmas, just my luck..

 

It's that time of year. UPS and other carriers are likely up their collective eyeballs in gift-giving alligators.

Curious though... why are you changing the oil pump?

 

DRUM ROLL PLEASE!! I am proud to say that I have solved the "ticking sound when coasting" issue. After long hours laboring out in the below freezing temperatures I got the truck back together and let it idle until it reached operating temperature to confirm I had no leaks. Went on a 15 mile test drive mostly through my neighborhood where I'm surrounded by houses/fences and can hear everything going on, and another 25 highway miles. NO FUNKY NOISES. Now I can't say with 100% certainty that the cam phaser is the issue, but it is definitely the most likely culprit. My truck now has all new cam phaser, crank sprocket, timing chain, timing tensioner and guides and oil pump. The oil pump was still good but with 130k miles on the clock I replaced it while i was there. The guides are plastic so they were worn but no more than expected, old tensioner took slightly less effort to compress than the new one, no visible issues with the chain and the crank sprocket seemed fine. The cam phaser is held together with 5 torx head bolts, I pulled it apart as much as I could but all the removable pieces seemed to be fine. A few things I took note of...

-the drivers side chain guide is updated with ridges on the sides (the original was just a flat surface)

-oil pan has to come off to get to the pickup tube bolt on the oil pump but on 4x4s it won't come all the way out just drop a few inches.

-every timing procedure I found says that after lining your timing marks up and turning the engine two full revolutions they will line back up, for me this was not the case. I pulled the plugs and hand cranked the engine about 30-40 times and they still never lined up but no internal components were making contact so I called it good.

- the timing cover gasket absolutely must be replaced!! After I got the cover off I decided I would reuse the gasket but upon further examination I saw that this also seals the coolant passages going from the water pump to the engine block and if it leaks there its gonna be sending coolant straight into the oil pan that will quickly result in catastrophic damage.

So to any and all other ram owners out there, even if this issue is just an annoying noise maker and never actually snaps a timing chain like it did on the chargers, challengers, ect. I can definitely say that doing this was worth the piece of mind knowing I won't have to rebuild my engine anytime soon. I said in an earlier post that I was going to just wait for whatever it was to fail and repair it then, but I found out a few weeks ago I have a baby on the way so that option kinda went out the window. Hopefully this helps a few others and if anyone feels like I saved em some cash and is feeling charitable I'll be glad to give you my PayPal info! Lmao

 

Awesome news! However, I'm gonna be the devil's advocate and suggest that the drum roll might be premature. Immediately subsequent to having my TC, guide and tensioner replaced, things sounded rosy. It wasn't until I'd accumulated a few hundred miles that the dastardly racket came back. I hope you nailed it but we need to know if all is well after a few or four hundred miles.

Can you elaborate on that? Why is the phaser the the most likely culprit?

Yikes! That ain't right. How far out were the timing marks after rotating the crank twice?

That's good planning and congrats on your impending sleepless nights.

Cheers,

Keith

 

Apparently timing chains do fail in the trucks. Interesting that the the complainant is making ref to the issue with the cars.

Hi Keith,


I agree that the proof will be after the accumulation of at least several hundred miles, maybe more. Mine came back after almost 25,000 miles.


I've been monitoring this issue for some time. There is one major difference between this repair and all others except one: the cam phaser was replaced. If I remember correctly, you did not replace the cam phaser on yours, and it wasn't replaced on mine either. I know of only one other that the cam phaser was replaced for this issue.


Hope your holidays were good.


Bests,
Dusty

 

Since you were able to do some disassembly on the cam phaser, may I assume there's a spring of some type in there?


Like Keith is saying, I think you need to put some miles on the motor to properly test the repair. I'm hoping this does solve the issue for you. I've been monitoring this problem here and on another site and I've been getting suspicious of the cam phaser since just replacing the timing chain and associated components does not seem to solve the issue in all cases. Please keep us informed.


Nice pics, by the way.


Bests,
Dusty

 

Im guessing it has more to do with the phaser simply because it is the only part that I couldn't examine to see if something failed internally. I was able to access The five fins inside of the phaser have a small L shaped metal piece behind each one and those all seemed to be fine. Soon as I get home tonight I'll be tearing the phaser apart completely, didn't do it wat cause its gonna require some drilling. There is what looks like a recoil spring inside it. (Like the pull string on a mower operates). As for the timing marks, after two full revolutions the marks were several chain links away from where they were supposed to be according to Chrysler. Not the first time I have found that a engine timing procedure was completly wrong. I will continue to post my findings.

 

Dusty, that's correct. I didn't replace the phaser because there was simply not enough evidence (anecdotal or otherwise) to support its replacement. I'm now in that shoulda/coulda/woulda camp in that regard. Good old hindsight...

Keith

 

Dusty, don't hold out on us. What other site?
