So here is my original thread 

 

After the RPMs drop from cold start my engine makes these weird ticking/knocking noise. The first part of the cold start is fine. no noise, sounds normal. Its after the idle settles down when the noise happens. Here is my you tube video. Watch until the end you can hear how loud the noise gets. sounds terrible.  I had it at the dealer 3 times. First time they told me to wait until I had 1500 miles. At around 2500 miles I go back in to have my first oil change and the noise looked at this time. They keep the truck for a bit over a week and they think it was an AC lines and or a lower radiator hose slapping against the frame and skid plate. At this time it fixed the noise but come to find out the fresh oil just made the lifter noise quiet for a few weeks.  Few weeks later noise is back again. It started quiet and got louder and louder.  I bring it in the 3rd time and now GM says its a lifter noise and they are aware of the problem but no fix is available at this time.  Some of the techs at the dealer weren't 100% convinced this was a lifter problem but GM engineers seem to think it is.   The dealer said I had to return my loaner and pick up my truck. They agree that it will be fixable at some point but agree that it is not healthy for the longevity of the engine. I called GM customer service and started a case. They asked if I wanted to pursue a buy back and I told them yes since they cant fix my truck. I hope this all works out. Not to happy with GM at the moment. I understand new truck have growing pains but this is getting out of hand. 

 

Watch the whole video, you will hear how loud the noise gets.

Well I changed my mind. Had it towed to the dealer so I could demonstrate the noise (cold start).  I asked the service advisor if a tech would come out and listen for the noise with me present to avoi

I wasnt assuming everyone has it. Relax. Just supprised no else has had this noise based on that gm says they are aware of this issue.

This has to stink for sure.

I wonder how many others or if there are more experiencing this issue?

I am surprised no one has had this issue on here yet.  I guess if you just hop in a drive and don't listen to it warm up outside the truck people may not hear it.

Stop putting mileage on it. More you drive it, less GM has to pay 

I wish I had the means to not drive it but it's my only vehicle.

I don't have it even after idle drops to 500 rpm. What makes you assume we all have it and just aren't listening for it? Mine has a little DI clatter but no piston slap noise like this. My 2019 is 10 times quieter than my 2014 was. Your truck obviously has some kind of piston slap which sucks man. First one of the 2019's Ive heard that sounds  like this.

The dealer still isn't convinced its a lifter noise. The noise isn't steady like a lifter and it only starts after the rpms drop to regular idle.  On some cold starts it wont make the noise. GM states it is though. My concern is longevity of the motor. Will this issue now cause problems if I keep the truck to 100k miles.

That's a shame on a brand-new truck.  Best of luck in getting a new truck.  If you decide to keep it, watch out for GM stringing you along with the "one of these days they'll have a fix" until your truck is off warranty, and then instantly joyfully wanting to fix it for you for several thousand of your hard-earned $.  I say that from experience.  And ignore those on here trying to hush you.  10 years ago, when I started asking about the AFM problems, a lot of people on here told me and others with problems to shut up, as it was 'only a handful of vehicles' and we were 'hurting their resale values'.  I didn't give a damn about their resale values; I was trying to get info on what to do about my truck's problems, as the dealers were sandbagging us, with an assist from corporate.  [Fast-forward 10 years and there are hundreds of thousands of verified, documented AFM problems that should've been a class-action lawsuit.]  I wish GM could pull their heads out and build a good bulletproof small block V8 like they used to!  Seems like their quality control is MIA.  Keep us posted.

just heard from a senior rep from GM. They were nice about it but at this point they will not do anything for me. Since the truck is drivable and not a safety concern they will not offer a buy back or let me swap it for another truck.  They assured me gm knows about this issue and is looking for a fix. They could not care less about the longevity of the truck. They said we could discuss extended warranty or monetary compensation once the truck is actually fixed but it could be a while before that happens.  I asked about other people who have had the lifters replaced already and she did not have an answer. She just assumes conditions must be different then mine. She made it sound like this is a well know widespread issue.

I leased this truck( with intentions to buy it at the end as long as it wasn't a turd). The current buyout from GM is around 39k. Trade in would be low 30s I would assume. I cant really afford a 10k hit right now.  My last 16 was a shaking turd. I should have learned my lesson but all other brands just don't do it for me. Should have bought a Toyota.

I leased this one too.  I guess if they won't fix yours, just mash on it.  When the lease is up, offload 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.

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

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.
