Just had a tick start on my 2022 ram 2500 with 6.4L hemi. Ant ideas where to start?

When does it do it?

I had a pinging sound and it was a cracked exhaust tie bar just behind the cats.

I welded it and the noise went away.

You may want to also check the exhaust manifold bolts.

I had experienced a tick on startup for about three seconds and it went away. First time it happened today, hoping it’s only a broken exhaust manifold stud, and not a lifter

If its a startup tick on a cold start that goes away within a second or two its totally normal. Nothing to do about it other than use oil filters with quality/silicone ADBV. The Hemi is sensitive to oil draining from the lifter galley when sitting resulting in a tick that goes away once oil pressure is restored. Annoying/crappy design IMO but not damaging.

I use Wix -xp filters
 
For the record I've tried almost every decent filter out there. I've had a slight startup tick with all of them. I'd say that Wix, and Fram Titanium have the least occurrence but it still happens.
 
Most likely exhaust manifolds. The coolant passage is too small at the back and the back of the block heats up more, no fix with out a reman. Jasper takes care of this issue it seems. So the rear bolts are the first to pop due to this over heating. ( does not cause engine cooling issues, just manifold) My 2018 ticked from almost new as well, and I started attempting repairs at maybe 125K. Now after so many helical coil inserts and such I had to give up, the heads are worn out from popping bolts. My advice is to deal with it as early as you can. Part of my engines demise was just excepting the tick I think and the holes just get stretched worse over time. Its so disappointing Ram will not fix this nightmare. I believe 2019 saw an updated manifold design, but obviously not working. As for lifter failure, my experience and opinion is with oil changes they start to fail closer to 175K or so. Maybe even longer if you do not idle the motor. But the exhaust while less serious, could lead to valve problems and other issues. So far I have skated by for lots of miles, but its nerve racking. My research has discovered;

> The Coolant passage design flaw in the block is the #1 Cause
> The manifold bolts are not large enough or long enough #2 Cause
> Ram would be bankrupt if they warrantied this issue, but I am astounded at the lack of effort to address the issue. ( RAM if you fixed this for the long delayed 2025 model please jump in and let us know!)
> Regular oil changes at or before the oil life meter is critical
> Never allow a Hemi to idle for long( wish I had know that, but the dealer does not say "These 6.4s are problematic, better never let it idle" LOL
> There is an interesting header to help fix the 5.7 but not the 6.4. I called them to see if anything was in development, and no.

I feel like Ram has a real opportunity to become a more reliable brand, and so many things have improved it seems its hard to wrap your head around. But not fixing the Hemi tick is holding them back.

Look, I REALLY do appreciate Ram taking a look at these forums. Its quite smart. But warranties are really not honored much at all any more with out a check engine light, recall, or some obvious failure that cannot be pawned off as something the consumer did. I just received a a 200.00 "diagnostic bill" from Ford Friday to "help me out" fixing a broken door lock on a Transit Van. It could not be warrantied because it was damaged....I took a look and there are almost 2 nearly invisible scratches from key insertion. To them it was an attempted break in :mad: I typically figure with rare exceptions I am on my own. So, with that out the way. What would be simply amazing instead of canned AI like responses that skirt all potential legal liability, would be engineers or other product managers having honest discussions about designs, and problems that need addressed so we know, say our next 6.4 wont be tossed away early due to a simple manifold problem. Or start discussions about what real Ram owners would like to see on the next refresh or generation. Maybe have some discussion public and visible so everyone can see how much Ram cares. And maybe some sensitive development work progresses via a more private setting with a smaller group of owners, with NDAs as needed. ( but everyone needs to know its happening behind the scenes) That kind of thing would be cutting edge and mind blowing. Way more then adding a 75" flat screen to the next model with 75 way seat massagers and 20K to pay for it. The respect a car maker would gain from such an endeavor could be priceless to brand loyalty, and product development. There are things that cannot be done, we all know that. We all understand emissions, crash testing, Federal regulations, and the effects of regulations on the brand in other countries. As someone who attempted this once, but the brand at question would not support the engineers, in just a few short months we solved a very silly design flaw, cleared up several insane miss understandings about the US market ( not a domestic brand obviously) and helped create the only successful TV marketing campaign that brand would ever have.

-Coolant system in the Hemi is just fine. Actually its phenomenal and overbuilt IMO - especially in the newer 6.4. The exhaust manifold warping problem is not due to a cooling system problem - moreso a manifold that doesn't flow well enough and develops a lot of heat. It is extremely typical for the ends of manifolds to break attaching studs/bolts on their ends before the middle due to the termination of clamping forces there. The manifold "bananas" for lack of a better term. Larger studs might help but in order to do the job correctly the manifold needs to at least be straightened on a belt sander - a straight edge used to check for true. Ideally a new manifold and all new hardware. If this isn't done it doesn't matter how many times you do the job it'll happen over and over and over. And heli-coils are garbage. If you've got bad threads for one of the studs then drill it out bigger and install a time-sert - its the only thing that will work and if done properly the threads will be stronger than OEM.

Exhaust manifolds leaking is common across multiple makes and models. Chevrolet/LS, Ford/5.4/Ecoboost, Nissan/5.6, etc etc. It is not even remotely a Hemi exclusive problem.

Oil changes have nothing to do with the exhaust tick you're describing. (however good advice for general maintenance).

Hemi idle has no effect on the longevity of the exhaust manifolds and the tick they develop from leaking. IMO the long idle theory as it relates to lifter health is seriously overblown and I've never seen anyone with a convincing argument as to how a "lack" of oil flow at idle contributes to it.... One guy said the lifters don't get very much splash lubrication at idle which might be true but the lifters are fed by and lubricated by a dedicated galley in the block itself. The lifters get plenty of oil. More than likely it is subpar metallurgy or hardening of the needle bearings that support the lifter roller itself. We see this on other MOPAR products like the 3.6 V6. Same failure. Totally different valvetrain layout.

OP don't buy into all the internet smoke. Just change your oil on time and enjoy the truck.
 
Sorry for the confusion. The no idle and oil changes are to prevent lifter failure down the road. And you are right, the coolant system is very solid. Its a coolant passage that is too small and causes the heat build up at the back of the block. But that does not cause traditional over heating. Its somewhat similar to the surprising failure of the prior Tundra V8 that's plaguing higher mileage engines. All be it it Tundras causes head gasket failure.
