Loud tick at idle

[samsquanch]

Good morning to all. I have never been on a forum before but I'll give it a shot.

2022 ram 3500 laramie 6.7l with 68rfe. Not sure if it's a HO or not. Truck has just over 65,000 kilometers and since my first oil change it's developed a consistent tick at idle and every so often when I'm driving. It would only happen In the beginning when the truck was warm. in the beginning as soon as I brought the revs up itd go away. Now it's way more often at idle and I've had it happen maybe a hand full of times while driving the truck.

I've brought it in several times to the dealer and of course they can't duplicate the issue. Well just last week it was getting worse at idle. Well I hopped in the truck and fired it up. Behold it was doing it right there. Walked back into the dealer and the service manager came out had a look and heard it. He got me to lift the hood and he listened around. Put his hand on the egr valve and immediately said it's the egr valve making all the noise. Correct me if I'm wrong but on my 6 other cummins trucks, not a single one has made a sound from the EGR. I said that's fine when it blows up I won't be paying the tow bill, and they can pay back all the money I've paid to have them look att he issue. I do have the full bumper to bumper warranty. I'll also state that I'm from Canada.

I'll post a video of the truck at idle with the noise. Bear with me I'm new at this and I'll try to attach the video. Any help or input is greatly appreciated from others who've dealt with this same issue or issues like it.

Ok, can't post the video because file size is to large..... it's only 7 seconds long. Any help on how to post a video is appreciated.

Oh crap, I'm not very good with this sort of thing. Thank you for the reply. I'll see if I can make a YouTube account and link it. I have never done anything of the sort before.

Are we allowed to copy paste a link from another web page and use it. There's a video I found that sounds identical to my trucks noise. But mines sometimes louder then other times.

Yes

That's what the tick sounds like in my truck. Sometimes it's a bit louder then other times. I have only heard it a hand full of times while the truck is running down the highway. If any one has had this issue and a dealer has found out what it is. I'd like to know what they dif to fix it with proof. The dealers here in Canada all say it normal operating noise. The truck has also stumbled 3 or 4 times at idle. Pay $100k plus for a truck up here in canada only to have it sound like a powerscrotum. Thanks to all who've helped. Totally new to forums.

Have you put your hand on the egr to confirm what he is saying?

Does it sound like this?

If you are talking about that ticking sound that seems to vary in its intensity up and down and seems to also follow RPM... That's very likely to be a lifter. These 19+ trucks are known to have this "issue".

All of the following is from the standpoint that it is a lifter (which to my ear it is)
Your mechanic can confirm by using a stetho on the driver's side of the block through the wheel well which is where the lifters live and likely will be able to pinpoint the pair for that cylinder that are louder. It sounds like only 1 of the pair.

Now here is the bad news, if you choose to go down the path of intervention, it will likely just be a set of lifters and maybe a cam if they choose, but it won't fix the problem permanently.

Now what you can do, if you choose, is try a different 5/40 oil (or 10/30 if your temperature allows) and see first if that has a lasting effect. The reasoning here is these lifters seem to be quite sensitive to operating viscosity and although any oil you should use meet ck4 there are going to be differences in their operating viscosities and additive packages relative to different manufacturers.

The good thing is that the lifter is only being lazy at idle. What you can do, which is never a bad idea either way, is start sending off oil samples when you change your oil to establish a Baseline and this will let you know how your cam and lifters are treating each other, and if you don't see an increase in iron in your oil then you know that although there is a noise it's not causing excess wear.

There is extensive information out there on this form and others about the typewriter tick or tick/noise at idle and it seems currently that the only permanent fix is conversion back to flat tappet lifters with appropriate cam and adjustable rockers. If you want to stay in warranty then your only option is through the dealer. In the meantime monitor with oil samples and wait for a hopeful TSB or recall but who knows when or if that will come.

Tempering emotions, with oil change samples, this generally isn't catastrophic, annoying yes but not catastrophic.

If you see increasing iron (in sample).. Or it gets much louder/consistent, then dealer ( which honestly will make it much easier to diagnose on their part depending on their skill level)

Yes, I have heard the ticking only s few times while driving. However it was when passing someone when she jumped up a gear. It's also stumbled just briefly a few times as well. I also put.my.hand on the egr and couldn't feel anything at all. Which.is why I told.the guy when it decides to crater they're paying the tow bill. I've also got the full warranty to 160,000km or 100,000miles. Or 5 years.

Yes I put my hand on it and couldn't feel anything. So I told the guy when **** hits the fan I'm not paying the tow bill. I've also got the full warranty till 160,000km.

I just had a service manager imply that 10w30 even if its full systematic is not a good idea, btw I now have the typewriter ticking part time, I got is some 300+miles after switching to 10w30, shortly will change back to 5w40

From what I've seen, there doesn't seem to be much evidence that the tick with these is specifically caused by choice of oil weight. Now that doesn't mean that there isn't some possible benefit of going 5/40 due to it being slightly thicker and alot of the 5/40's seems to favor higher molybdenum. So a bit more cushioning/anti-wear could be helpful.

As far as 10w30 and a service writer's opinion, putting this as polite as possible, unless that person has a closet engineering degree ... I'd not give it much weight, time, or thought. Additionally, Detroit diesels have been using 10/30 conventional and/or blend for quite a long time now...

But opinions being what they are... Don't listen to mine either, do your own research and come to your own education based decisions.

I only used shell t6 5/40 in my 2011 3500 had around 500hp and can't remember what it had for torque. Truck had 500,000km when I had to sell it. Did oil changes every 10,000km. Every time I'd di tge change the oil was still fairly clean. I don't mind this truck but the regen crap is annoying. My 2022 keeps doing a regen 2 or 3 times per tank.
