Ok here we go one more lifter question, according to some fan members  on this forum there is no lifter problem with those engines . It’s all in your head .

The big portion of lifter issues was a select production window from September 2020 to March 2021.  This was the known window of manufacturer issues with the AFM/DFM lifters.

 

Some 2022 LTD and all 4x4 2022.5 trucks with the 5.3 have DFM disabled still EXCEPT for NHT Max Trailer Package trucks due to the chip shortage.

I'm a heavy line tech at a chevrolet dealer and I can 100% tell you that the 22's have lifter concerns as well. (personal experience)

What about the 6.2?

6.2 still has DFM enabled.  Not affected by the chip shortage.

That is not correct, I am on my 2nd 22 LTD, both have had DFM ENABLED

What trim?  I know most all LT and some LTZ have it disabled.  All NHT its functional.  Not sure on High Country, it might be enabled on those.  

 

Refresh 2022 all 4x4 5.3 lose DFM.  2wd and NHT keep it.  All trim levels.

Both were 5.3L 4x4 High Country. The first had everything installed & working, current one came without Auto stop (no retrofit) & Park assist not enabled w/ later retrofit. Both have/had DFM, still undecided about a Pulsar LT or an Autosync to get rid of the DFM

Engines are built at Tonawanda, NY, regardless of where the truck is assembled.

This explains why the engines keep on blowing up , they are built in NY by democrats.

You know the tonawanda plant has been assembling engines for GM since 1938, right?  Politics aside, as much as i really hate liberals, that does not mean politics involve issues with engines due to an issue involving part sourcing.   They assemble the engines with the parts they are provided.  The issue has been the parts they have been sourced.  If there was an issue with the liberals assembling our engines for us, it would have popped up since 1938 already.  But here i am talking to a wall again.  Can only provide so many facts before you go "but muh dodge" when they have the same lifter issue.

With engine components sourced from China, India and Mexico.  
 

Waiting for GM’s next $50 billion taxpayer funded bailout.

Actually not true. Engine components are sourced and machined in factories in ohio, michigan, and new york.   Looking at ac delco oem engine parts, i have only seen USA made components.  Only parts made in mexico are hoses belts etc.

    • 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.
    • 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?
