In the spirit of troubleshooting, are any of you guys able to hear this noise in park or neutral when you give the engine some gradual RPM?

 

I'm experiencing something that sounds pretty similar to this noise in my 2015 Silverado (5.3L 13k miles), but it's only when I'm in drive going down the road, and only when there is slight throttle being applied (may continue under more throttle but engine noise likely drowns it out). No noise when coasting or when revving in park. Severity fluctuates day by day and sometimes I don't hear it at all. The 2014 Sierra (5.3L ~40k miles) doesn't do anything similar.

 

I guess I'll try giving it some gradual RPMs in neutral or park after the engine is warm, can't really remember if this sound presents itself immediately when the engine is cold or not.

 

Similar to some others in this thread the noise seems to be coming from the driver's side footwell, or at least the driver's side of the vehicle. I'm just stumped at the fact that it only wants to make the noise when throttle is being applied, and so far as I know only when the vehicle is in drive and underway.

 

I'll get it looked at soon, and hopefully will have some useful info to report back.

Have you found anything. Thats the exact same issue i have only in drive under light throttle. I have recently swithed from 87 to 91 octane and for some reason hasnt made any noise since then 2 weeks of no ticking. Strange

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

UPDATE: Since June i've been to the dealer 4 times and had 3 drives with technicians to diagnose my engine tick. the replaced the fuel line to the DI pump. It didn't fix the problem. the noise has gotten worse to the point that it is ticking very loud in V8 or V4 mode. pulling a trailer it is ticking like a sewing machine.

I have driving my friends 2014 LTZ Chev and it works perfectly.

 

Finally got it in again today and the dealer called saying they have ordered a new fuel pump for the truck. Fingers crossed this will fix it.

Well whats the update is it gone now wirh new fuel pump

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
