Anybody have a engine tick warm or cold ?

[@californiajeeping]

Did you have a rough idle? I traded my gas for a diesel and NVH is much lower than the gas.

My 2020 3.6l had a rough idle and tick like the rest two dealers said it was normal and wouldnt teardown unless it was on my $. I bet we have the same symptoms that are related. Multiple misfire when driven hard, rough idle, ticking/rattling etc.

I have an appointment with the dealership in early July, but hoping to take it in sooner. 21 Sport S and just hit 7k. That tapping is just too distinct to ignore. I could care less about general engine operation noise. My YJ ( may she rip) was loud and my XJ (everyday) still roars, but neither had a tick/tap. If I learn anything I’ll be sure to share.

Mine sounds exactly the same. Upon start up until it reaches temp and subsides a bit or goes away completely. I have had it not present itself once or twice as well. I may have the dealer inspect during my final free Jeep Wave svc. Keep me posted and I will do the same!

Do any of you guys have like a fluttering sound ? I have one around 3k rpm’s. Now it’s starting to sound in lower rpm’s as well. I have a slight tick at start up. Thought it was lower octane pinging. Went away for awhile when I started running 93 octane, now it’s back.

And my luck with Jeep has been the opposite. Mine is so quiet, both my wife and I have stopped the truck and started to get out before realizing we didn't shut it off. Very quiet engine.
She actually has gotten out of her Grand Cherokees forgetting to shut them down.
No MIL lights, no misfires. It starts, it runs, it's quiet (except for cabin noise and back in 2019 the dealer saw I was driving a Silverado and warned me the Jeep would be LOUD, and any wind would be very annoying. He wanted me to know........... hey, I've driven early Broncos and Scouts from decades ago, Blazers, etc. - might as well be running your tractor. Rattles, wind and more. This truck is relatively quiet compared to those, cabin is not quiet compared to a thick walled, insulated Chevy.
I expected it, dealer made really sure I knew all about it (he was concerned)

Multiple reasons the doors and main top stay on a lot here - heat, wind, 100% relative humidity, dew points 91 or better.......... high UV warnings. The hot wind in the summer will take your breath away, when you are hit with a side gust of 30-40 mph, it's like someone stuck a Hoover hose on your face. The other thing is our "forecast for today is for clear skies, gentle breezes and no chance for rain" and 2 hours later, a gully washer, 5"/hour. Or worse, a record-breaking derecho and the forecast was for mostly sunny, no rain.
So - you take off doors and roof at high risk. Wear plenty of sun block, take a hat, tie the hat on your head, and remove anything that can move from the cabin - the wind will remove it for you otherwise.

Anyway - no engine tick other than the expected injector and valve train sounds that are normal.

This is what I consider normal engine sounds. Ignore the crap K&N filter I have since thrown away - this was right after getting the engine in, before I got the air box rigged up and made other tweaks -

What do you think about this one. Video taken from drivers side wheel well. Sound i think is passenger side. Hard to hear. Just a couple minutes after startup. Seems too light to be a rod. But too slow for upper engine stuff. Seems too loud for injectors.

Same pitch and cadence as my vid above. Watching.

Yes, that’s what I’d consider to be normal engine noise…for a 30+ year old vehicle.

I had a ‘95 Mercedes E300D and I also had a CDL, so I get what a really noisy engine is.

Who knows…maybe it’ll quiet down after it’s first oil change. That’s how my ‘16 Ram was (noisier approaching oil change time).

Mine had a tsb for a pcm update on ticks and noise at idle. Might be worth looking into for those of you experiencing it. Mine's near silent at idle

I'm curious as to how a PCM update would impact mechanical sounds - especially valve train.
Valve timing won't impact mechanical sounds,
Valve lift is a function of the rockers and oil supplied via the solenoid valves on each end of the head. It's either got pressure to hold it in low lift mode, or it doesn't. The PCM for that is either go or no-go, not "we'll adjust pressure".
Valve lash is controlled hydraulically like the old days.
I know of the one for misfire detection, but am not familiar with one for valve train noises, which are mechanical in nature.

Well the Gladiator needs another camshaft/rockers and lifters. Opened up FCA ticket and was told the work will be performed. I then said what about a new engine and was told no its under warranty. I said I don't want to do this every 2500 miles and again was told it's under warranty. That's BS, as soon as it is repaired I am getting rid of it. So done with FCA!

I have lots of racket when the engine kicks down from cold start, and then a steady tick before it runs at peak temp for a while. I can hear it best from the driver side, both inside and outside the vehicle. Sometimes it’s louder than the video sound. Any thought would be appreciated. After the axle leak repair, I just dread more BS to deal with.

Get ready for the FCA runaround!

I would tell them that since this is the second time - I would not be surprised if it counts as the same problem still unresolved so you could be tracking for possible lemon law actions.
and/or
Tell them they owe you a full 100,000 mile warranty for your troubles.
Since it's the same problem, still unrepaired, you MAY be able to add the number of days together to get to the lemon law terms in your state.
The problem is that the warranty will run out at some point - and you'll be stuck, so I'd not let up on them quite yet.

so your saying that's the sound of a bad cam/rockers?

I thought this was a 2020/2021 problem... I seem to have the same noise with a 22, although a tad quieter, at 1,700 miles. Maybe I should be getting mine in the shop. ugh what a mess

For mine, the tsb was 18-042-22A , but mine is manual, and the TSB number is different on the autos, so I have no idea what it is for you "normies" with autos.

Short videos taken on low end equipment from under a vehicle aren't very telling, IMO. I'd want to be there and hear it from above, from the area of the valve covers.
Videos made with mics like that distort sounds a bit from "being there" and then there's the conversion and uploading to the web, then the reproduction on the other side. I have yet to see any video made that once it gets to someone at home sound exactly the same as it did in person.
And under the vehicle - that's not where you pick up valve train sounds. That's where you hear exhaust, rattles, knocks of crankshaft or rod.
The entire valve train is on top - in fact, more on top than any typical V8 from years ago.
The overhead cams are on top, any sounds made will be on top.

this was made from the wheel well, drivers side. but I do get your point. could you describe, if you dont mind, what the sound of this 'problem' should be like, as well as what sounds ar normal? I'm not new to engine noises and problems; however, I am new to these newer vehicles...... Just dont want to go unnecessarily to the jeep dealer because they already told me that steering clunk is 'normal' lol. plus its 2 hours out of the way. and I honestly thought this was resolved for the 2022 MY. but maybe not?
