Watch this video or skip to 7:37. The stuff quiets this truck down significantly. According to the Lucas bottle, you could add up to 1.6 quarts of the stabilizer to 6.4 quarts of 0W-20 for a 20% concentration.

Yes I am having the same issue however I don’t really think of it as an issue. The engine is operating normally, it’s just a bit of an annoying loud design.

The only other thing I can think of that it might be is if you drive around in 4hi or 4auto all the time and eventually the front diff fluid broke down and you’re now hearing gear noise from the front differential.

Mine does it too, 2016 Sierra slt all terrain. Really annoying. It directly correlates with how much I press the gas, when I let off it dies off     Sent from my treestand using Tapatalk

Has anyone been able to resolve this issue? Chevy has told me it's normal time and time again but now at 106K miles it got louder and this time when I dont hear it the check engine light remains off and give it about 30 miles later the ringing/Chattering gets louder and the check engine light comes on. Obviously theres a code being generated but some how no one knows what it is because the code is a rough idle code... its frustrating to say the least...

Good day,

 

Not sure if anyone is following this topic still however I had a very similar noise on the drivers side of my 2018 Yukon with 5.3. They changed the oil pump and the fuel lines (fuel line has a check valve that sometimes rattles) and on the 3rd visit to the shop the Tech started taking parts off and going for a drive to check for noise. He discovered it was the heat shield on the drivers side exhaust manifold that was making the noise. I took it for a drive while the shield was off and yep no noise anymore. He is putting back the heat shield and ordering a new which he'll change once in. So if the new one rattles then I will up date this post later but for now looks like my mystery is solved.

Hi, I believe I have the same issue. Can you confirm that replacing the heat shield resolved chatter/fluttering noise?

I will post soon as the part just came in so they will be installing it in next day or two. Once I have a chance to drive it for a day or so I will let you know if it is for sure gone.

Hopefully your heat shield replacement will fix it. Can’t wait to hear more about it.

I’m sick of this fluttering noise...

Did anyone ever figure out a fix or what exactly shattering noise is? I have a 2019 Suburban and this noise is driving me crazy! So obnoxious!

      My First Project and GMC has me stumped

      By davester · Posted

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.
