I have a 2012 Silverado 1500 with the 5.3 gas engine with 100,000 miles on it . A year after buying it new it started a clicking noise that came from underneath the passenger side of the truck when it is cold. I took it back to the dealer while still under warranty to get it diagnosed and fixed. They kept it overnight so they could start it cold and hear it. I went back and the technician and shop manager told me it was an emission valve clicking that sends gas fumes to the charcoal canister. I said replace it. But they told me the new one would do the same thing. Now I’m very tired of hearing it and I want to fix it. What is the best route for this?

Well, why not replace that part and see if it actually does fix it?

 

How can we diag the problem through a keyboard? The dealership may or may not have told you the truth when they tried to figure out the problem. If the new part makes the exact same noise, then they were right and you will have to live it.

My 2011 has that at times and not at times when I start up.  But on the driver side.  I don't hear it after the motor warms up some.  I've been told its a lifter and is a common issue with 5.3 engines.  I've been driving it since I bought it used in 2019.  "If" it is a lifter the dealership told me it would likely fail at some point and to fix this is about $2800.  My independent mechanic said his truck has it too and I should just drive it because that was what he called the "Chevrolet tick".  I'd be interested to know how yours turned out.  Interestingly enough my niece has a 10 year old Ford F150 that had this same issue.  Hers eventually locked up and ruined the engine, which she replaced with a Jasper engine ($8k).  So, I'd be interested to hear how yours turned out being my reply is 11 months after you posted.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I have never seen GM instructions for the other trucks as per the HD with the 6 speed or the half tons but had got the impression that the HD trucks with the 6 speed were not having the same problem that the 10 speed and pan presented. Also video that I have seen of the HD 10 speed with the gas engine starting in 2024 model year showed that it was a real struggle to even make it work when pulling down hard on the exhaust after undoing the exhaust hanger bracket on the side of the transmission as after all there is little room for the pipe to even go down behind the Y joint as it soon would hit a frame cross member. Also that they had tried just like I did with the gasket off and no way was that pan coming out any way they tried to manipulate the pan. From that as well as the local transmission shop talking about the pain in the rear issue, I was not expecting my pan to come out because GM shows it was not even intended to come out without dealing with the exhaust piping.    It would be nice to claim, here's what you do and its easy to remove the pan guaranteed on any HD truck with the gas 10 speed but dollars to donuts the next guy trying what I did would not have the same luck as the exhaust was just manufactured slightly different and be pissed off at my claim that the pan comes out with no issue. Its more of a try and see if your particular truck might work like mine did .... or not !.

      Sorry I didn't see this until now, but it works on both the 6 speed and 10 speeds, as well as all the half tons too.

      Engine vibration after motor mount replacement.

      By 1998sleaze · Posted

      Hello, I have a 2018 GMC Sierra 1500 that I recently changed both motor mounts on due to the driver's side being blown out. After replacement I seem to have a steady vibration that I can feel in the pedals and the back of the seat. At this point I'm convinced that the aftermarket "Anchor" branded mounts I used are not performing as well as OE, the only real reason I ended up using the mounts in question was because my local dealers were out a few months to get a Driver's side mount. I've tried "Neutralizing" the mounts according to the motor mount TSB published for these truck to no avail. My trans mount is also in great shape and seems to be absorbing vibrations swimmingly. As far as I can tell there is no issues idling, my idle RPM is steady and I've recently put GM plugs and wires on, however, I have not cleaned the throttle body or intake valves. Any one else have a similar experience with aftermarket mounts? Patience certainly is a virtue that I wish I exercised here. Thank you!

      The TCM has to be flashed before it can drive.   If you installed it the way it is, it has the OS (operating system/program) from the 2010 truck you got it from. That will not match with the VIN/OS pair that your 2013 truck has.   You can do the full install. Then tow it to a dealership and they can flash the trucks PCM/TCM with the latest program for your VIN.
