Yeah that definitely is not the case with my truck or anyone else’s with this problem that I’ve heard yet. Sorry to hear man, that is crazy. My truck is at 23k now and the motor doesn’t consume or show over filled a drop of oil, great gas mileage too. How was your gas mileage?

My 2014 Silverado is at 120,000 and running just as good as day one, not one issue with it. I know there’s problems out there, but complaining to others saying “should of bought a ford” doesn’t help

Just got this from a buddy at my local dealer. Looks like Chevy is aware and they are working on a fix. Sent from my iPhone using Tapatalk

Well. I got my exhaust on today. I can definitely say it’s not the flapper valve or the stock cats. As stated above, my oil is a little over full. I may send it for analysis and see what happens.

Also look at your oil cap and see if it has any condensation and if it smells like gas.

I’ve never had a vehicle that the oil cap didn’t have a SLIGHT gas smell. That’s normal at least I thought it was. I checked mine and it has no condensation at all but that very slight gas smell

Yes slight is normal, mine smelt like you were standing over an open gas can and I have a feeling the condensation was gas that was splashing on the back of the cap. The tech smelt the gas as soon as he pulled my dip stick didn't even have to put it by his nose it was that strong.

Gotcha. Yeah I do remember on my 06 Silverado before I traded it in I had two burnt cylinders that lost some compression and the oil cap definitely had gas in it, you could see that condensation and the smell was there. When I just checked my 16 Sierra there was a gas like smell for sure on the cap but the only thing I could see on that cap was just oil. Oil level was normal as well. I wonder if this is the problem that a lot of people have with these half ton GM trucks and it’s a time bomb. Yours happened with super low miles though and on the trucks I’ve heard people complaining about mine included there are no issues at all. Did your truck throw any codes by any chance?

No codes the only thing is my oil pressure gauge started running 5 lbs lower at operating temp. After driving this loaner they gave me my truck was way down on power.

Was your ticking sound focused only on the driver side footwell or was it across the whole dash?

Mine was only on the drivers side.

Eek. Did it go away for months at a time and then every once in a while a bump would trigger the sound and then it would go away?

I only had the truck for 3 months so I can't say, it started at about 6000 miles and at 8200 started getting worse.

Gotcha. Mine definitely has gotten better, more than worse. It’s so weird. What did the dealership do when you brought it there to diagnose this and perform the fix? You brought it due to overfilled oil you said?

      The whole story is false. The screw is there as a temporary fix to allow the pump to even turn on. When the nozzle is returned the pump shuts off.. At this point people are just being punked   https://youtu.be/1DtlaEuHXAA?si=06mrRmw9HLUwdeRk   https://www.facebook.com/share/v/1CyRZdsaSc/ https://www.facebook.com/share/r/1DxV1Hyrqi/       SNOPES: https://www.facebook.com/share/p/19HPYUnRik/

      Not exactly what I was hoping for, but I do like it. I wonder if they'll bring back Smokey Quartz Metallic? 🤔 https://gmauthority.com/blog/2026/06/here-is-the-all-new-2027-gmc-sierra-1500/

      Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.

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

      By bluev8 · Posted

      New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.
