I live in Florida and have had that noise on all 4 of my LT motors from '14-17'. Sounds like oil starvation of the lower bearings for 3 seconds. Can't be good but the all do it, cold or hot. 

There have been engine pre-oiling systems available for decades, I've never felt the need to install one, but sounds like the newer 5.3's with the new design oil pump might benefit from one.

A bad service experience like this can reflect on the brand.  I'd take my concerns to GM customer support.  I was discouraged at one point and was going to take my service to another dealership 40 km up the highway.  I reported my concerns.via customer survey and now receive great service at my local dealership.  GM expects consistency in service throughout their dealerships.

I never have any noises on startup with my ‘17 5.3. What oil filter are y’all using? Make sure you have one with a good ADBV (anti-drainback valve)

I use a Wix (Napa Gold)#7045 or AC Delco PF63E on all of my vehicles. When I use the Wix my oil analysis comes back with lower better numbers.(its a better filter) But either way the sound is identical with either.  My new '17 Denali 6.2 did not make the sound initially, and I thought some change was made. But within the first months it was definetly the same as the others with 7k on her now. It is the loudest on the first cold start of the day on the outside of the vehicle. I think most people would not notice it inside the vehicle if they were not listening for it. Seems gearheads and mechanically inclined people notice it as not a normal start up sound.

I live in Florida and received one of my free oil changes on two different 2015 trucks that I owned. One was a 5.3, the other a 6.2. I noticed both times on the receipt that the part number for the oil was 5w/30 Dexos approved?? I asked why wasn't 0w/20 used? Was told thats what they use in all of them and it was a dexos synthetic blend, better for the heat in Florida. 0w/20 is for fuel mileage. I have only used 0w/20 once and have used Mobil 1- 5w/30 for 4 years in all of my LT motors since. My oil analysis is perfect. I tow, and it is Africa hot here and I haven't had one issue. After break in and 2-3 oil changes my change interval is 5 -7500 miles depending on use.

 

The start up rattle is the exact same with 0/20 and 5/30.

      Ac not keeping up

      By Aimatdeer · Posted

      2024 l8t . Ac has never felt really cold even new. But lately it seems a little warmer. When it gets in the upper 80s and a little more humid it just does not keep up. And sometimes at idle it gets warm. My wife's 2008 envoy is better. My son's 2016 is colder. I have an apointment for a third try Monday the 29th at a third dealer to try and get cold ac before my warranty is out. The first two told me something about so many degrees under ambient temp blah blah blah seemed like they didn't want to mess with me. This was set at low. Max air fan speed high. 87 degrees and a little humid.   .

      OCI, not when but why?

      It isn’t all that bad in the world with purchasing power versus quality. My first car had just basic equipment. My oil choice was conventional oil. The life expectancy was around 100K miles. During that time you could expect to change all the accessories. Today with inflation you can buy the equivalent. It comes fully loaded with 4 doors. The life expectancy passes 100K miles replacing no accessories. If reaching that milestone is your goal you simply follow the recommended service intervals. If you want more miles simply do more maintenance. When in doubt you can check the internet or YouTube for information. The selling of any product hasn’t changed since the beginning of time. The power of the buyer has. The price of the product hasn’t changed much with inflation. The buying public wants more. Competition and the buying public has put the sellers in a box. The greed is on both sides. You can still get more for less. You just have to do with less. That used to be popular. The buying public has changed . It’s the sellers that are trying to keep up. As Grumpy tries to inform the readers in this case with maintenance. If you want more. More effort is required. That information wasn’t available this easily just a few years ago. I believe the public has more power. Getting information is easier.

      2023 DRW Wheel Liners

      By SFC Retired · Posted

      Gentlemen, I'm new to this forum. My question is, I thought I have read somewhere that the rear wheel liners for 2024- 2026 GMC Sierra HD3500 DRW can/will fit the 2023. I can't seem to find that information again and wondering if anybody has any knowledge if these will work or not with the 2023? Part# is 84892542. Thank you for any information. The GMC parts counter wasn't able to give my any definitive answer?

      Spacers aren’t safe anyway, so you’re better off just buying something else.

      OEM Trailer Hitch Receiver - Impact tightened by shop

      Its because they have thread locking compound on them. I would bet money that they are actually reusable and not a literal TTY bolt because GM and most other OEMs don't trust techs and the end-user to apply thread locker properly in the same way they don't trust anyone to solder properly (and instead instructing crimps everywhere). Torque To Angle =/ Torque To Yield.   If you think dealerships or any technician replaces every 'discard' bolt in every procedure, I have a bridge to sell you.
