I figured someone might correct me on the exact name of that part as it was just something I threw in there because it seemed pretty important to get that done ASAP, where as the ticking from the cam phaser is probably just an annoyance.

I’m at 190k on my engine and other than the ticking it seems fine. Was your worn cam showing an signs of failure? Noises, codes, etc?

 

Operators who are impending members of the 'Failed Hemi Camshaft Club' may experience clicking/ticking on start up. The engine will otherwise appear to start and operate just fine until they lean into the go pedal. Many of these unfortunate folks are consistent in reporting the way in which the cam failure becomes manifest. Leaning into the go pedal, RPM increasing past 3K and all hell breaks loose. MIL starts flashing, engine starts bucking/shaking and now you’re in a 3-ton roller skate. Querying the PCM will typically provide you with a misfire DTC for whatever cylinder is affected by the failed cam lobe. It appears that, in many of these failure events, the cam per se is not the failure mechanism. Rather, the roller assemblies on the lifters are failing and the cam lobe becomes collateral damage. That’s a theory - it may be the other way around.

We know that FCA is saying nothing so there are plenty of theories making the rounds as to what’s at the root of the issue. Many are blaming the oil viscosity specified by the MDS Hemi and the lack of zinc in those oils. Many more are blaming it on extended idling. There are myriad other theories. My take: The cam and/or lifter manufacturer has an inconsistent QC issue. There are far too many of these engines out there that have hundreds of thousands of miles under their respective tires. They’ll obviously last a long time if the collective total of the parts are built correctly. However, that’s little consolation for those of us faced with hideous repair bills for something that should be lasting much, much longer.

 

It's been quite a while since we last communicated Chilly. Hope other than your engine problems you are fine.

Since I've traded off my 2010 with the coast down ticking that symptom is far less the mystery that it was four or five years ago. Although I haven't heard of one in some time now, the techs around here seem to zero in on the cam phaser pretty quickly. The last one I know of was a 2015 with 70K on it. That's been over a year now and I've yet to hear of one since. I think they've finally figured it out.

At one point on mine I strongly considered a camshaft problem, especially since I learned they were using 35 a month nationwide. When they were operating on my engine they said the camshaft looked fine. However, I saw the camshaft out of a 2013 that had a groove in the cam lobe in what appeared to caused by an immoveable lifter roller. I put over 100K on a 2014 and had no engine issues at all using 5W-20 motor oils. We'll see what happens to my 2019.

Anyway, you have been a patient and significant information source regarding this issue and I, for one, sincerely appreciate your contributions.

Best of luck,

I believe that “ticking at startup” probably was occurring on the engines that failed, but was possibly not a symptom tied to the impending doom. Most Hemi’s tick at startup because the exhaust manifold bolts are broken and the exhaust leaks till it heats up enough to seal. The header bolts are way undersized and tend to snap as the dissimilar metals they connect cool at different rates. One should see which side ticks at startup and check those header bolts.

Thanks for the video. Definitely seems to be a poor Choice for lifters by Chrysler.

 

Indeed, the Eagle Hemi has become notorious for its ticks and general valve train racket. I'd also been dealing with failing injectors over the past four yrs and when they begin to go, they sound (tick) very much like a collapsed lifter. The exhaust manifold bolts on the Beast were replaced twice on one side and three times on the other. The bolts that fail are exclusively those locate adjacent to cylinders 7 & 8 because the aft part of the engine runs hotter. They were broken again on one side when I recently sent her down the road. FCA has reportedly been employing an updated (material) fastener to remedy the issue.

 

Dusty, appreciate you comments - thx! I'm doing good but am having trouble lately... Can't seem to wipe the sh_t eat'n grin off my face.

Well I have read this forum completely, I believe, and have not found one person(s) that had this issue (the ticking noise when coasting with eco mode on) after 2011 model, correct me if I’m wrong. I have a 2014 model that I have never had an issue with until my engine blew up on a road trip at around 114,600 miles, no warning signs of any sort, blew up a hole on both sides of the block and one through the oil pan. Always changed the oil myself since new with amsoil filter and air filter religiously at or around 5000 miles, mostly highway miles, the factory pre set on oil change is 10,000 miles. Now I had a new crate motor put in it from jasper motors, not mopar. Supposedly it has better components and what not. And i have about 1200 miles on this motor and this ticking problem just started. It is under warranty and I am wondering if I should have the cam phaser replaced first or what and has anyone else had this problem after 2011? Or should I just buy a tuner and turn off the mds and not worry about it. Also going to call the shop that replaced the motor tomorrow and see if the timing chain was broke( maybe it did and caused the first motor to fail like the charger/challengers did)

 

Good gawd! The whole forum? That's a sh_t load of reading! Or what you meant is that you just read this long-winded thread.

Why did your OE Hemi blow up? What failed?

The cam phaser in your Jasper engine should be fine. Cam phasers post 2011 were redesigned.

DO NOT, I will repeat, do not interpret your engine's ticking as problematic. The late Hemi engine's valve trains are, by design, mechanically noisy. If it's persistently loud when the engine is hot, I would be onto Jasper. If it's ticking after a cold start and goes away, she'll be fine.

 

Still grinning! I thought the Hemi was fun. It was but...The HO Cummins in the new trucks will overdose ya with testosterone. Got a sick Hemi - get a Cummins!

 

Well here it is 2020 now and my 2010 Ram 1500 Sport 4x4 has developed the baseball card in the spoke tricks, 135000 miles. Still runs like a champ however not looking to put a ton of money into it if I can avoid it. A lot of great information as to what the problem may be.
From what I gathered I should start here...

Timing Chain/Guide/Tensioner
Cam Phaser
Lifters
PCM flash

Oy...........
