Am in the clear on the lifter issue?

Thanks

You should be fine. Mine was built on 3-18-21 and I have 13,000 on the clock and she runs great! Break point for questionable engines was 3-4-21.

Thanks, getting close to the 8k mark on the odometer, glad to know this issue is potentially behind me.

Anyone……What engine plant is “A”? Just picked up my 21 Trail Boss 5.3 that was built on 8/31/21 so hopefully out of the woods!

Thanks!

Look like I missed the cut off by 1 week, I am running Pulsar LT to shut off DFM and Auto-Stop.

Can you tell me what plant?

All AFM/DFM lifters are inferior to the 2500-3500 lifters and could fail. Its just that the ones from September 2020 - March 2021 are even more subject to failure. If durability is more important to you than fuel mileage, buy a 2500.

Thanks! That's funny because the window sticker says engine country of origin: United States. Ugh.

Engine was built in US truck was assembled in the Mexico plant, many if not most of the parts are shipped in.

Yeah I get that, but according to Firehawk99, my engine was built in mexico even thought the window sticker says US.

I could be wrong but you have the 5.3. Which is only built at Tonawanda NY-T, Spring Hill TN-N St Catherine's Canada-K and Mexico which I believe is A. I'll have to double check.

Thanks for info. Yeah, I guess it wouldn't be out of the realm if the window sticker was wrong. Heck, they built my truck with the wrong back window (no tint at all!!), had to have that replaced. If you do find out for sure what "A" plant is I would like to know, just because of my curious nature if nothing else. Thanks again!
