Collapsed lifter AFM issue

Looks like I just had my lifter issue appear - 2016 Silverado 6.2 liter with 108k miles.  Suddenly misfiring badly (engine light, traction control lights on dash).  P0304 misfire code on engine.  Local shop ruled out plugs, wires, coil packs, and fuel injector.   Reading the forum is sounds pretty typical of this VFM induced failure.   

QUESTION - I probably want to keep the truck long term (comfy, fast, and still paying it off!) so the choice is either (1) have a local shop fix the lifter(s), get it running right, and use the plug-in VFM delete controller.... or (2) fix it with the new cam and full mechanical delete kit (if I am using close enough tech terms).   If going with the normal lifter fix and plug-in VFM delete, does it solve the problem of lifter collapse in the future as well as the full mechanical delete?  I like the V4 highway miles, but not enough to have this threat of collapsed lifters hanging over my head forever.

And do you think its wise to have them change the timing chain while in there?  Anything else??

And before you visit the dealer, try driving the same trip in manual mode, M5, as mentioned above to help diagnose if is AFM you are feeling or not . Sent from my Moto Z2 Play using Tapatalk

Make a copy of the bulletin as provided in the previous posts and show it to the service manager. Ask why he isn't doing what GM states should be done. Escalate issue to dealership General Manager a

I am having the same issue. 
I have a 2015 Sierra all terrain 5.3L 

60,****** miles on it. 
Brought it to dealer with Check engine light, traction light, smoking, shaking, etc.

dealer said I have a bad injector.  $1300

i said ok. After waiting a week for the parts to come in. They started to work on it and then call me saying I have 2 collapsed lifters on 1 side.  
They also say my power train 5/75,000 is expired 

obviously I’m well under 75k but it’s 5yrs 8mo old.  
service manger says they’re gonna “talk to the rep” on Monday and see if they can get it covered for me.  
is there any chance they will fix this ? 
or should I prepare for battle ? 
thanks

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
