Can anyone identify this knocking noise?

Have you tried using a mechanics stethoscope?

Is the sound when cold or hot?

The expensive tick everyone is afraid about is when hot, at idle, and isn't a consistent tick, its inconsistent and pings around, unlike the sound in your video.

What repair does this tick cause?

I have a 2024 Hemi 4x4 with 25k miles. It's been developing a ticking/knocking noise. The dealers told me it's normal and that they can't hear a problem. "It's got Hemi tick." "This manufacturer's engines get noisy" they told me.

The video is from underneath. It can be heard from anywhere. I'm aware of the lifter issues and the exhaust problems. This sounds like a knock. It sounds like its coming from the bell housing, but it could be from anywhere. I've sent the engine oil to blackstone for analysis but it looks clean visually.

Any help or experience would be appreciated! What do you think it is?

no that is not normal as another person stated the Hemi is a very quite motor that sounds like lifter issue , they need to fix it , good luck.

My 2020 Laramie ended up needing camshaft and lifters at 39K, and it was like showroom new at 5.5yrs. Lucky I had an extended warranty. The invoice totalled $5,500+! Sold it and got a 2026 Laramie with the Hurricane, and not looking back. Quicker, faster, more powerful, and the sound isn't important because sound don't feed the baby! 10yr/100K mile warranty to back it up. Really nice truck.

What repair does this tick cause?

This tick is the "bad" one, essentially a failed lifter which will require the head to be removed to access the failed lifter. Often requiring not just a lifter (or lifters) to be replaced, but also the camshaft. This will likely include "while you're in there" replacements of other lifters, etc.

This repair from an independent shop can run into $3,000 - $5,000 or so out of warranty.

Could be, not sure though, but kinda matches, especially if this is a hot engine.

Yeah it's hot, that video is yesterday after a 30 mile drive from work.
Gonna hit it with a stethoscope to try and rule out anything on the lower end of the motor but im leaning towards a lifter...hopefully its not a rod knocking or piston slap

Rod knocking is like a hammer on an anvil but little softer, would most likely have spun a bearing already, piston slap, almost like a rod, just softer, where the skirt hits the cylinder wall due to a gummed up wrist pin.
This is from my past experience with a`97 expedition and a 2000 grand Cherokee. The Cherokee 4.0 six actually broke the piston skirt. What a lovely simple engine to work on BTW.

Thanks for the info. Ill update when i figure out what it is, hopefully it is JUST a failed lifter.

If thats the case while im in there im going to do a mds delete.

Looking for honest thoughts. I have a 2020 Ram 5.7 Hemi, 88,000 miles. Ticking sound extended into clunking sound. Lifters and camshaft required and dealer has given me best case scenario of $6k, worst case scenario of $7,200. I asked about complete engine replacement and that price was $9k. I am edging towards the $9k but would appreciate any thoughts, I really do not know much about engine mechanics. I have an extended warranty but they are refusing to cover it as the fine print in the warranty dictates that all oil changes must be done at a commercial enterprise, I have been doing my oil changes using Mopar filters and Royal Purple oil, I have all the receipts but did them at home which is why they refuse to cover repairs (expensive lesson to learn).

There is no need for a full engine replacement if it is a failed lifter/camshaft.
I just had a failed lifter along with casting failure on the camshaft on my 2019 Ram 1500, 60,000 miles, did everything for about $3,000, thats including a MDS delete kit, upgraded oil pump, and getting my computer unlocked for the MDS delete. It took us from Friday after work to Sunday evening, the weekend before last.
I know you said you dont know much about engine mechanics but just wanted to give some insight.
Get quotes from a reputable mechanic outside of the dealership, i don't see why you can't find someone to do the work for around
$4-5,000.

POOLBOB, CONTACT RAM CARES. THEY CANNOT DENY YOUR WARRANTY FOR DOING YOUR OWN OIL CHANGES. SOUNDS LIKE YOU STILL USED CERTIFIED OIL AND FILTERS. USE YOUR RECEIPTS TO BACK UP YOUR CLAIM. THEY CAN ONLY DENY YOUR WARRANTY IF OIL IS NOT SPECIFICALLY CERTIFIED. READ BELOW...
"To maintain your Ram 1500 warranty, you must use a full synthetic oil that meets Chrysler material standard MS-6395 (for gas engines) and carries the current API (American Petroleum Institute) certification. While Mopar/MaxPro oil is recommended, any reputable brand meeting these specific standards is acceptable."
YOU NEED TO CHALLENGE DEALERSHIP'S DENIAL.
GOOD LUCK!

I'm looking at purchasing the same truck. Told the dealership i hear the ticking noise and they say they don't hear anything. Its been in for service 5 times in the last 5 months. 31k miles. Even though i know something is wrong, most likely exhaust manifold bolts, will the dealership be responsible even after factory warranty for repairs being the problem hasn't been corrected.

Thank you. I'll reach out when I take it back. There's a problem somewhere. I'm waiting on the oil sample results. The dealer did eventually offer to drop the sump to see if there are iron filings on the magnet. They would have to remove both front knuckles, drive shafts, and the differential to do that, though. That would probably do more harm than good. Sampling the oil and filter contents should get that data without the overhall.

Did you ever get it sorted out? Good, bad, or was death knocking on the door?

 

[woods767]

It isn't fixed yet, it's the same about 6k miles later. I'm going to take it to a different dealer. It's still under warranty.

Edit: The only new clue is that it knocks every other revolution of the engine. So by that logic, it could be a cam or injector.

For OEM warranty and Mopar extended warranty, this is true. If he purchased a 3rd party extended warranty, it may have had other stipulations like this in it that he agreed to when he signed it.
