Heres the ticking noise I’m getting.. 2016 Sierra 28k. Different than what everyone else’s is reporting. Wtf

I have this same, slow tick coming from under my truck. Its very clearly from under the truck, and is not the valve train or injectors as mentioned in this thread.

Anyone else have or know more about this noise? I can post a video also, but it is exactly this same sound.

 

Thanks for the help

I bought a 2015 Chevrolet Silverado 1500 Z71 Crew Cab 4X4 with the 5.3 engine. I've had it a week and have noticed a ticking noise that sounds like it is coming from underneath the truck at the bottom

They are a bit noisy. Normal noises include:     On the not so normal noises, we did have to replace the vacuum pump on a 2014. Truck sounded like it had a lifter tick. You could hear it from t

I have heard small exhaust leaks present themselves as a tick sounding noise. Since you are mentioning it coming from the bottom, might be something to investigate.

I purchased a used 2015 Chevy Silverado LTZ Z71 Off Road, 5.3L, from a local dealership in the middle of January 2017 with 21400 miles, now 22800 mile. I never noticed the noise while driving the truck but when I was out of the cab with it running it sounds like it's more than a minor ticking noise. I took it back to get it checked out and the Service Manager at the Dealership said it was normal, took them a week to tell me that.

 

I'm not a mechanic but I'm having a difficult time with their analysis so I recorded the noise for others to listen to - https://goo.gl/photos/uof3kuzJuJ2y7sns6

 

I'm at a loss and this is a sound that shouldn't be coming from any vehicle with less than 25000 miles. Another thing is that I have noticed that the oil pressure shows 30lbs when warm and idling.

I know I’m coming in 4 years late, but mine is doing this EXACT same thing. Did you find a fix

Besides my reply from last night has any one seen a fix for this?

Welcome to the site.

 

Have you replaced the vacuum pump, or had the update done on it?

No I haven’t… but UPDATE and most likely the solve/culprit. 
 

ok, I have a buddy of mine that works on Chevy fleet vehicles. Had him get under it today. Culprit is the torque converter guys… it has what he described as a “flaw” but not a fatal flaw. He said the torque converters on these trucks are notorious for rattle and whining. Meeting with him Saturday to do a fluid swap and an additive that is supposed to quiet the noise. He did advise me that these transmissions are notorious for going out at the 150,000-200,000 mark so be on the look out for that as well.
 

Hope this helps y’all, I’ll keep you updated after the fluid swap and additive are put in. My trans fluid needs a good swap anyway from the looks of it. There was supposedly a bulletin issued for this but I can’t find it. GM Blamed it on “over lubrication”. This is the same dude that I’ve gone to and diagnosed problems (correctly) over the phone in the past.

Did you ever get this diagnosed or determine what it is? Mine has almsot the exact same sound as the video you posted, sounds like it's coming from the bell housing or just infront of the transmission pan.  Hoping it's nothing to be concerned about?

I bought a 15 Sierra 5.3 4x4 about 6 months ago. I started noticing a tick coming from the engine in the passenger side. I took it to midas the mechanic said these engines are known for the ticking sound and that it's nothing to worry about. I had them do a motor flush to see if it would fix it and it didn't change anything. I also used Lucas fuel injector cleaner and that didn't fix it either. Does anybody know if it's something I should worry about? Any suggestions?

Where are you at with this? I have the same slow rotational tick/knock coming from the flex plate/torque converter area.... maybe this is normal on the 2016s? Seems to be a lot on here with the similar noise. I just bought it with only 49k miles on it. My 2013 did not have this sound.

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔

      cam upgrade in CA

      By AidenVorpagel · Posted

      hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you

      Possible lifter tick after DOD delete

      By B14Sierra · Posted

      Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.
