2022 2500 HD 6.6 Gas. From day one there is a ticking noise best heard from the front passenger wheel area. Dealer didn't think it was an issue but bugs the crap out of me. 

Pretty vague I realize but any thoughts?

The direct injection system can be known to make a ticking sound.

 

Kinda hard for us to really say without hearing the exact noise.

Thanks, it's really low around the bottom of the belt. I can try and add a small video in the next few days.

Can you add more about the tick... Is it a random, does it sound like it has rhythm to it? Is it loud like a hammer tapping on iron, or something else. DI engines tick like crazy!

Consistent when engine running.  Fairly fast rythm.  120 bpm ish. Loud enough to hear from anywhere outside the vehicle.  

 

Didn't hear it on last 2 trucks .  But they were the 6.0 not 6.6 gas.

I don't believe the 6.0 is GDI but the 6.6 is. Circle back to Cameron's post. It's high pressure fuel pump ticking. Even my lowly 4.3 does it. You get use to it.

Thank you for the response.  Appreciate the info, thought it was a service issue but seems not to be.

 

Curious, Why does it make that sound?

Mine has this same tick almost sounds like lifter failing to hold pressure. And creating push rod slack .Seems to be less annoying when its cooler out say 50 degrees and lower. My 2019 5.3 had a tic but not like this one does. I went as far as removing the passenger valve cover to check the valve train. After hearing about GM valve spring issues. 3,800 miles no issues. Chocked it up to the character of the 6.6 l8t DI engine. 

 

OP did or have you changed your oil yet. Mine got louder after my first oil change. But has calmed down a bit as the oil gets older.

Yea sounds like mine. passenger side is very audible. I dunno if the high pressure pump or its cam driven lifter is a different design. But sounds more like pump noise than the typical injector pulse sound. Who knows it "aint broke"   so i just live with it.

Mine is a 2022 Silverado 2500Hd and I get this slight ticking upon acceleration.  I've used the same fuel and everything since purchased.  Not sure what it is but bothers me thinking of lifters?

      Wow I'm in a pickle. (Broke down truck) and a story.

      By richard wysong · Posted

      I had an 88 K1500 with a 5.7 that had those symptoms, I know totally different, it ended up being the ECM. Once you get the fuel system fixed if it still runs lousy you may want to investigate that. it didn't set any codes, stalled ,ran rough at times etc

      Trading 7.3 (Godzilla) for G.M.C gas

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.
