Mine`s been making this ticking noise since 5 miles or so. Last night I ran the piss out of this thing. 5600 rpms more than a few times.

 

If it had bad lifters, would it have blown up by now?🤔

I had a non-AFM lifter fail before the AFM lifters did in a 2010 5.3. Several of them actually wore out the lobes on the camshaft. Oil had been changed religiously every 5,000 miles, too. Mobil1 full synthetic. Only code present was for a dead misfire on cylinder 2(?), and was obvious no matter what we did. We changed everything on the affected cylinder from the coil, to fuel injectors, to plug and wire, to downright pulling the valve cover. NOTHING surprises me anymore.

The most current version of this covers to 2024 - 19-NA-218 1..3   I listened to your video again.  Definitely is engine related.  Lifter not pumping up, broken valve spring, bent push rod.

Ouch.  The rattle issue sucks too but ouch for the engine.  That blows.

Mine does the same thing since new. `25, 5.3. Goes away when hot.

GM has an audio clip in TSB 23-NA-170 of bad crank bearing and its not an intermittent noise like what you've got going on at idle in your clip.  Its a constant noise.  So I don't "think" your issue is lower end.  23-NA-170 1..3  Dealer can pull up the audio file in the TSB. 

 

They can run a power balance per PI5832A to see if it can isolate to a top end or bottom end noise - MC-11007011-0001.pdf

 

It does not sound transmission related as others have suggested.  There is a TSB for 10 speed noise concerns with audio files that the dealer can pull up.  The noises are very specific and are gear, bearing or fluid level related.  TSB is 24-NA-264, service dept. can play the audio.  

A gentleman and a scholar. Thank you. I submitted this to the service advisor and he said he appreciated the heads up and will most certainly have his tech looped in.

I noticed today, at 2600 miles, this ticking was mostly gone. This thing has been doing this ticking since new. Go figure.

Oh boy. What broke….?

Iv`e got my factory warranty. As we used to say," it`s either gonna go or blow." I ran the piss out of it last night. Seems happy now.

I do have 5w30 in it.🤫

Have you been running 5w-30 in it since you bought it?

Of interest;

 

On new vehicles, the various mechanical and electrical systems adjust during the first 6,400 km (4,000 miles) of routine driving to provide optimal fuel economy and transmission shift performance.
Electrical systems will adapt and calibrate during the break-in period. A one-time occurrence of clicks and similar vehicle noises is normal during this process.
Normal driving charges the vehicle battery to achieve the best operation of the vehicle.

***Dealer started a case. Tick is engine related, the rattle is transmission. They’re going to start teardown tomorrow.***

They’re replicated my concerns. Tick is engine related, rattle is transmission related.

I hope everthing gets fixed for you. I have had 3 T1s and have had no problems so far.

 

Knock on wood.

It’s aggravating. I read on another post that the rattle could be exhaust valve related, with age…but my truck has less than 700 miles on it. I guess that, if the case is exhaust valve, I got a bad one. That still doesn’t explain the tick in the video at idle, CLEARLY coming from the engine.

 

I've had 3 T1 trucks, and only one was not problematic. It was a 2021 LT Trail Boss, 6.2/10 speed. It had 12,000 miles on it. I had to trade up because my job status was questionable and I had a baby on the way. Now I regret doing that.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?

      Tire pressure for 37s

      By PBNB · Posted

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
