2020 6.2 with 1500 miles. Tapping sound. Do I have failed lifters??

Upon startup this morning and yesterday and letting  the truck warm up I noticed a off sequence ticking/tapping sound.  I know there is a TSB for lifters so I did the same thing again morning to check.  The noise is still there.  I revved the engine gradually taking it up to 2000 RPM and the noise disappeared.  No DTCs according to my OBD scanner.  See video.  The sound is most prominent from the driver side wheel well.

 

Do I have an issue or am I just paranoid?  I have a road trip coming up from PA to FL in September and don't want to be stuck on the road.

Sounds like normal injector tick to me.

And here I though Amsoil cured all ailments?

I can't tell if its injector noise or lifter tap.  Though the dealership will assuredly tell you it's normal, I would take it in just to have it checked so you have documentation of it if anything happens in the future.

Thanks.  That's exactly what they said.  It's normal and won't to anything to investigate further.  Even my GF noticed it when I pointed out the noise...And she doesn't know anything about engines.

 

I guess I'll just wait until it gets worse/louder or starts doing it on acceleration.  A that point I may just trade it in for a Duramax.  I really don't trust any of these low grade techs tearing into my engine.  When they repaired the oil cooler connector leak they topped off the oil and it was overfilled by at least 2.5 quarts.

Sounds like my wife's Verano.  My LD isn't quite so obnoxious.  Direct injection is noisy, especially on start up.  Mention it at the dealership the next time you're there. Under warranty, you've got nothing to lose.

Thats not normal you can hear a hard tap

Maybe of interest.

Thank you.  Interesting and good read.  It's not happening on acceleration or when the engine has warmed up and driven a while.  Also got an OBD2 scanner and it's not throwing any code.

 

Guess I'm just ultra sensitive after my oil leak experience and reading all the troubleshooting posts.

I have a 2020 Trailboss with the 6.2L. I've watched a few of these threads and finally decided to test my own vehicle. Upon startup when cold (outside temp was 68 degrees) that engine clanks and pings in a way that is scary sounding. For 3-5 minutes I actually thought for sure the motor would come apart when towing my trailer home and then suddenly it was gone. When we hit the road and I had to stop I let the motor idle for about 10 minutes while stopped and never heard it again. Very interesting, but certainly a scary noise to hear for a few moments!

Curious-  What oil and filter are you running?

Amsoil 0w-20 and an Amsoil filter.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      The BORA 3/8" spacers arrived yesterday along with the extended lug nuts. I got the front wheels changed out today, but was overheated and covered in sweat so bad, I figured getting both front wheels done was a win, and took a cool shower. Hopefully, I'll go out tomorrow morning before it gets into the 80+ temps and do the backs. After getting the first wheel snugged up, I backed out one of the lug nuts then hand turned to count threads. I believe I stopped counting around 12-13, so I think I'm good there.

      My fullsize truck is averaging over 26mpg so I'm pretty happy with the increased fuel economy targets. When I had my gas Silverado (2020 5.3) it was averaging 21. Again, for a fullsize truck, that's very different from the 12-15 these things used to get 30 years ago.   Whine all you want, increased MPG is a good thing.

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

      By bluev8 · Posted

      That is a fair point, and I think an OBD-first proof is probably the right next step. I agree that the value is not the hardware box by itself. The marketable part would be the software: always-on capture, baseline learning, event reduction, system-specific reports, and alerts. Also agreed that if an OBD device is always plugged in and has local storage, it should not miss the event in the same way that a scanner plugged in after the fact would. The only thing I would not want to assume yet is that an ELM327-class device gives all the late-GM data needed at the rate needed. Standard OBD live data, DTCs, freeze frame, Mode 6, VIN, and calibration information are definitely the right starting point. GDS2 also proves that a lot of useful ECM data can be viewed through the DLC without needing a DTC first. The question I need to test is whether the data needed for a useful GM V8 event report is actually available through the DLC, and at a useful sample rate: - misfire counts / roughness by cylinder - AFM/DFM state - oil pressure and oil temperature - fuel trims - voltage / reset context - U-codes and communication events - calibration / software information - whether these are standard PIDs, enhanced DIDs, Mode 6 data, GDS2-only data, or not available So I think the right benchmark is: 1. Build the OBD-only version first. 2. Keep it plugged in and logging locally. 3. Compare it against GDS2 / freeze frame / HP Tuners or another higher-end logger. 4. Measure which parameters are available and at what update rate. 5. Only justify ECM-side hardware if it captures useful evidence the OBD version cannot. So you may be right: the consumer product might simply be an always-plugged-in OBD event recorder with much better reporting. A question for you: when you say ELM327 devices can already deliver all the data needed, do you mean generic OBD Mode 01 data only, or GM enhanced data as well? For a useful GM V8 report, would generic OBD data be enough, or would you expect the tool to include enhanced items like misfire by cylinder, AFM/DFM state, oil pressure/oil temp, U-codes, and calibration information?
