Is the "hemi tick" still a thing in the latest models?

My 2015 developed the tick at around 40K. They fixed it under warranty. The next year FCA reduced the powertrain warranty from 100K miles to 60K on new ones. In year five, 65K miles both sides were ticking... Since I had the 100K warranty they fixed both sides one involving a manifold. At 75K I traded with NO ticks. I spoke to one Ram tech with years of experience and he said he just cut to the chase on his and got titanium lifters? I think that was what he said. He described what happens that leads to it in detail and how the titanium ones due to their hardness are not affected. Of course, I'm not a Ram tech so it might cost a bit more...

So, is anyone aware if they finally fixed this well known "issue" with the 5.7? I sure don't want to get a few years down the road and start hearing that again...

Yes it is. There is tick due to manifold leaks (either bolt snaps or the manifold cracks), and there is tick due to lifter issues. They did fix the main lifter tick back in 2014 or so, but there will always be a non zero amount of hemis with this problem it seems.

If it's your manifold thats cracking, you can replace it with shorty headers and be done with it permanently.

If its bolts snapping but your manifold is not cracked, you can get your manifold machined flat very lightly to take out the warp, then reinstall with new bolts. This seems to be a permanent fix for bolts snapping.

If it's your lifters, many have good success running Redline 5w-30 and a Royal Purple oil filter <--- this may void your engine warranty because Redline is not certified, but it is definitely a better oil than factory spec, they just never bothered to get it certified. But run at your own risk of course.

Just took to dealer for exhaust noise heard by service tech for oil change (Pennzoil 5-20 syN). Dealer found crack in driver side manifold. 24k old man’s truck. No heavy hauling and mixed city and highway. Absolutely love the truck but bummed that this showed up and known issue. Waiting for part with patience.

2020 Limited with the works!

My understanding is that older (e.g., 4th gen) had a problem with the manifold bolts sheering off due to heat/expansion/vibration leaving the bolts in the block. This caused the manifold to "tick" loudly and was kind of a PITA. In an attempt to fix this issue, RAM changed the design to use a stronger bolt. So now instead of the bolt failing, the manifold (being made of weaker material than the bolt) cracks instead.

Could be off but that's what I gathered when learning about the known issues with the 5th gens.

100% yes. Mine had a very pronounced tick until the day I sold it.

My 2019 just broke the passenger side rear bolts. I’m waiting on two warranty repairs at this point. One for a steering rack failure and now the manifold.

Well brought my truck in for snapped bolts driver side exhaust manifold , and it was about an hour and half ,before convincing them it was covered under powertrain warranty I have 44k on a 2020 1500 big horn , I can't believe that I had to call FCA and the place of original purchase, before they would even check it, FCA said it is covered till 2025 or 60k where I got the truck from but nobody would call each other to confirm , the truck is in south carolina and I bought it in new york ,
They quoted me $1600 for both sides changed out , now with warranty they will only replace driver side not passenger side , I dont get it if its under warranty you cant do both sides ? it is an upgraded manifold , the passenger side is easier , ????? if it fails after 60k then I might go stainless headers ,
I always have bad luck getting warranty work done Thats y I dont buy extended warrantys I have yet to waltz in someplace to get something fix without a big stressful drama scene , But I hear other people walk in get loaner cars and their truck fixed and detailed with out any drama , what is up with that ? O well at least 1/2 is getting done anyway , Just a little rant

Wait, what? They are only honoring just the one half of the pair? That's ludicrous.

My dealer has a guy almost dedicated to these things. He spends a large percentage of his time doing them under warranty mostly. Apparently there is a bit of an art to getting the broken bolts out without damaging the manifold. I spoke with another tech on a forum who "since he could do the work" and when the first one went he just went ahead and spent the 800 bucks I think he said for the upgraded manifolds and titanium "lifters?" that he said solved the problem. It is an intrinsic design problem for the engine, something about dissimilar metals and temp differentials between the block and the manifold and having to do with the downstroke on the cylinders. Most of it went over my head so that is what I remember from a few years ago when I was dealing with it and I could be off on details as I was plugging what I read/heard into my sparse database in my head. It was apparently why FCA shortened the power train warranty from 100K miles to 60 starting in 2016 I believe I remember being told. I had the first one go out at around 40K. then at 60K, they did both sides. I kept it another 10K with zero problems and traded here six weeks ago. I also heard that FCA/Ram decided actuarily (or whatever it is called for mechanicals) it was cheaper to continue to fix em than to go back to the drawing boards or upgrade the materials. Adding four or five hundred bucks to the engine cost per unit as an "upfront" capital outlay per vehicle was apparently prohibitive whereas a warranty fix hits a different financial stream that is more favorable from an overall fiscal standpoint to both MSRP and from a tax, write off over time perspective, was my interpretation. I did a bit of a deep dive into it a few years ago but not from a mechanical standpoint. If you do a search on "hemi tick" and Ram's I think it will get you to some of the other Ram forums where it has been discussed and discussed. I think the 5th gens, for the most part have yet to have this particular issue raise it's ugly head. And since this is a dedicated 5th gen forum, that may be why it has been discussed so little. That's sort of why I asked the question. It IS a consideration for RAM as eventually they will move away from the Hemi's. And ongoing "threat." I don't believe the 6.4 suffers from this particular issue... But, there is an entire after market designed to address the problem with specific parts designed to address the intrinsic design flaw. BUT, other than this, the engine is extremely robust from a design standpoint and thus it has this issue, but few of the issues other engines often have. It is actually considered an "obsolete" design by most engineers. Essentially it is "old tech," but boy does it sound good...when it's not ticking...

Curious... wouldn't the exhaust manifolds be considered part of emissions instead of drivetrain? Might be different from state to state, but generally emissions related components have longer mandated warranties and I would argue the component responsible for collecting exhaust gasses pre-cat are most certainly emissions related.

(Ya... I know... RAM and every other mfg. will classify it any way they want.)

This is interesting. I took my 19' to the dealer where I bought it. The dealer offered a 200K/20 powertrain warranty when I bought it but said exhaust is not covered on the warranty. My truck was "one of the early 2019's (August production)" and did not have the upgraded bolts that they started to use in late september. Long story short, I have replaced nearly all bolts on the passenger side from the back to front. The most recent was all but one of my manifold bolts broke and when the quoted the work, they said the Driver side was easier and would be $550 for parts and labor (new manifold, gasket, studs) and passenger side was $1000 because it was the more difficult side. Luckily Mopar sent me a coupon for 20% off parts and labor. If my driver side starts to act up, Im going to a muffler shop and replacing the entire system.

Now that I think about it... manifolds are definitely part of emissions because CARB has regulated aftermarket ones into the ground. Again, it's probably state by state.

If mine goes again definitely going with headers stainless something less ridged than cast iron., ,,,,Where I bought the truck they said if its bolted to the motor its under power train warranty, because it is a documented problem to avoid class action suit cheaper to fix it ,but anything after the flange isnt covered it took about an hour or more of phone calls they have been getting away with charging people before I walked in there and I am sure they will do it if no one says anything !
