3.6 Engine Tick

[Hootbro]

Does that mean drive side is bad?

How does it sound off idle? Does it ramp up when you blip the throttle or go away?

Will share a video of warmed up idling and blipping the throttle, sir. It is too big to upload directly. There is a whistling noise around 4s, right after blipping , which I didn't notice when taking the video.

I have been taking quite a few videos in the last two weeks while reading the 16 pages thread.

Dropped it off at dealership today. The tech took test drove with me explained the passenger side noise is from a fuel purge control valve mounted on top of the engine. The service advisor checked and no code in the system.
They kept the truck overnight to test drove it in the morning when engine is cold. There is a fairly loud tapping sound when accelerating with a cold engine, peak around 2K rpm. It becomes faint after engine warm up, but sometime I can still hear it when stopped at the light.

Honestly, sounds about normal to me.

Took the truck back from dealership. They didn't find anything abnormal, yet.

Also asked about mods and warranty. Got a quote of $6K for 2.5" mopar lift with 35x12.5 KO2s on factory wheels. Looks like they want to charge $2K for labor. If it were for 37x12.5, I might jump on it.

Are you wanting something wrong with it?

Nothing you have posted leans to or even the dealer thinks you have a abnormal tick.

If you are super paranoid about it, have a oil analysis done and check for iron wear levels and go from there.

No. But I want to have it checked before spending money on mods

• This an observation only
• No, I did not buy a Gladiator for its gas mileage.
• You might have different observations and I could be full of shit. But thought I would share my experience.
• I like to tinker and do as many of my own mods that I comfortable with. But, I’m no mechanic. (Some might say enough knowledge to be dangerous.

I have a 2021 Rubi with 12000 miles and as many of you reported I also have the engine chatter. I don’t do my own oil changes and each time I have taken for service I mention the engine chatter and get the “We will have a look” statement. Inevitable, the final feedback is we could not find any issues. And to be fair, following the oil change the engine is noticeable quieter. For reference I have the oil changes between 4k and 5k miles. Also, there are times when I have stopped at Jiffy Lube with the same results, chattering going in and quiet or coming out.

Getting a bit nervous about needing a lifter rebuild at some point based on posts. I was thinking back to my granddad who swore by a dose of ‘SeaFoam’ as the ultimate in engine protection, so I thought why not. I bought both the formula for the crankcase and the fuel system and followed the instructions not hoping for much. When applied my oil life was at 45% and the engine was chattering as usual. Within 20 minutes of adding the engine was as quiet as any other vehicle I own or have owned and again this observation is from an unscientific perspective but the engine just seemed to run smoother and easier.

Now for the freaky. Today I took a 300-mile trip, I kept to 65 mph, and was using the cruise control like normal for interstate runs on roads that was a mix of flats and mountins. For the trip I averaged 21.3 MPG. I have never, ever, had this kind of mileage since purchasing the jeep, running the stock 33s Wildpeaks, and again I generally don’t care about mileage. Face it we are driving bricks. My normal MPG averages have been 13.5 around town and no more than about 19.5 on the highway since the day I took delivery. After getting back home I took another listen and there was still no chatter coming from the engine.

I’m sharing because I see the posts about engine rebuilds and granddad may have known what he was talking about. In fact when I read the posts about needing rebuilds it makes me want to go back and buy the extended service contract. I still love my Gladdy and have no plans to part with her but based on my experience with service and oil change behavior one may believe that the problem is the recommended oil is not sufficient for these engines over time? I would be interested to hear if anyone else has had similar experiences or thoughts.

I have another trip next month and will add and update on my experiences at that time.

Cool story. I’ve wondered about that stuff in my engine to see what happens with my never ending high IRON count on all my early oil analysis reports.

My 2nd engine is somewhere around 50k kms, runs extremely quiet, and all the wear metals are low except the Iron…. So I might give it a shot to see if it magically helps.

As far as the mileage reading that has surprised you, …did you reset the odometer when you filled up?

I did not do the reset and was at an average was around 15.5 before starting out. Good point though, next trip I will reset and see where it ends up at. It’s was so jacked up to see that range number, had to do a double take.

Mine had it happen - just got it back yesterday. Replaced both Intake and exhaust cams, rockers, and lifters. Dealership had it for about 2 weeks. I *almost* forwarded this thread to my rep at the dealership. Didn't think it would win me any brownie points though.
It was covered under warranty. Thankfully. I did the Livernois tune about 40k miles ago.

If you're getting that on winter blend then great things are coming this Spring.

That's a smart way to approach it. Most upgrades are a wash on the resale market.

Get the oil tested at the next change, as others have advised. It's a little bit of money for a lot of peace of mind.
You request the kit (free), and then pay when you send it in.

Purchased in June 2019, currently 86k miles, started hearing the famous tick of the 3.6 Pentastar like 8 months ago and the noise increased slowly until I decided It was moment to do something about it. I leave a video here to show you how it sounded.

I saw couple of videos online and read threads here, and the most common thing is the failure of the rockers, which cause a play in its movement and eventually damaged the camshaft. So based in these videos, where people was doing the job, I was thinking to do it myself, then I thought to bring it to my friends from a Stellantis Dealership in Mexico, where I used to work couple of year ago, to get a better price, but currently they are short in personnel and I was not sure if they have the same technicians and capable people to do this. Also I looked around for local Engine shops, but not luck or the service and prices I expected. I ended up in my local dealership, located McAllen, TX, same where I did all my services while I was under warranty, they are good people. Reference: After my warranty ended I continue to do my oil changes myself every 5k, so no problem due to lack of maintenance.

The result was, damaged intake rocker arm damaged from codriver side which caused damaged to Intake Camshaft. Taking advantage that both heads were open when the diagnostic was been made, all Intake Rockers were changed (I then though that I messed up since I could ask to exchange the exhaust rocker arms since they had the Heads open, each rocker arm coast around 11 dll, but well lets hope they are ok for another good amount of time). I think the cost of everything was ok, based on the prices that I have seen here, labor and parts, with a 10% discount was $2,844.27.

I have seen people here with these engines failing at 22k miles, others above 150k miles without a problem. So is there actually a trigger cause? I put a snorkel around the 40k miles, is there a chance that the increased air flow cause an extra out of spec pressure and lead to a premature failure of these rockers? Is just natural result of the lack of rocker quality or the engine design? were all that Mud, Sand, Snow, Rocks, donuts too much for the engine? All of the above?

Hope this fixed last for a long time, before anything else fail.

I just got a tick in the last month and its getting worse. I hear it at slower speeds and the sound goes away sometimes. Yesterday I hit a bump in the road and it went away for a couple seconds then came back. Any thoughts? 2020 LE with 52k on motor

I would send in a oil sample, they are pretty cheap now, just to see if your cam lobes are getting scored. You could also up your oil weight as your mileage may have altered tolerances that otherwise wouldn't have been heard with the thinner oil. 5w-30. Id check with the dealer first before running thicker oil in case it screws with warranty.
