Haven been here much in recent years but I still have my 09, though it’s been relegated to farm/beater so to speak.  But still a valuable member of the family and just rolled over to 100k miles. At less than 5 k miles I had Blackbear delete AFM and do a very mild tune, as well as to the tranny ECU.  I’ve been very good about oil/filter changes at around 50% on the OLM. A few oil analysis came back fine every time.  May have used 1/2 qt last change. No engine or trans problems despite pulling 4000# boat at highway to freeway speeds for 10-15k miles over a few years I’d guess. Got a dedicated better puller in 2018 and 2022 ….from the dark side 😉


Anyways, so I’m jump back on here and refresh myself with the goings on with these trucks and see a lot of talk about lifter failures…. 

Question on consensus- is it just a matter of time till my lifters fail? Anyone take a guess as to a percentage of these 5.3 AFM  that will despite short interval high quality oil changes?  
 

As I understand it, neglect could make it more likely with clogged screens and low pressures.  But it also seems there is a degree of randomness (suboptimal lifter design) to the problem?

I’ve heard of crazy expensive repairs, and replacing the lifters prophylactically might not make financial sense.  I’d like to keep this truck for hauling stuff as well as hauling the dog, but don’t necessarily want to hang onto a grenade.

Oh brother here we go again....

 

 

Personally I would delete it ASAP. It is probably less than 10% of vehicles that have lifter issues though.

Well, it was deleted 95k miles ago…

But the percentage is encouraging. 👍🏻

But seriously I would consider deleting it. It is not a very difficult job to do at home in the garage if you have the space for it.

LOL I have lots of space, but not that much bravery or skills- dirt bike top ends is about as far as I’d go!

But I do have a shade tree type guys with the skills.

I think your more frequent oil changes are a huge factor and your worrying about something that may not happen. Now is not the time to be buying any vehicle.

True that.  It took me around 4 months to get my ordered truck.  Yea, I’ll probably just keep an ear on it for now.

Let's recap here:

 

  • 100K miles of trouble free service.
  • The AFM is tuned out.
  • You do approx. 3500 mile OCI's.

 

Your way past the point were a defect in metallurgy (heat treat) would be an issue EVER. 

Knowing that most lifter failures (99% of the >1% that fail) happen as the result of a mistimed switching event (oil foaming or low oil pressure) and yours NEVER EVER switch....

Your OCI length keeps lifter guides happy....

🤔

 

What is your concern again? :dunno:

 

Give it a sharp and complete tune up (including trans, diffs, UOA) , keep doing what you do and drive it another 10 to 15 years. 

 

They sky is not falling......😬

 

And if you still can't sleep drop it off at my place......

I'll take that grenade off your hands, for free naturally, me taking all that risk. :crackup:

What diyer2 and grumpy said are true no need to worry about something that most likely will never happen to you :)

BUT I hear a lot of this stuff saying how frequent oil changes are why the lifters never fail and that is a laughable claim imo. The K2XX with AFM that my father owned got it's oil changed whenever the truck's oil light popped on, and we all know that thing comes on when it feels like it, and that truck lasted over 150k miles and went on many a trip with no issues. I know some guys who change it religiously at 3.5k-5k and they still had failures.

 

I just think it is mostly random.:fingersx:

I ask a service writer when my vehicle was approaching 120K miles if there was any reasonable time frame to replace certain parts. I referring to wear parts such as starter, alternator, wheel  bearings things that could ruin a trip, especially now. Of course certain things effect that life, highway miles or town driving. With the exception of my past collector vehicles 120K miles was the max in mileage for me or 5 years.  They were little help.

Thanks for the thorough recap, Grumpy.  What I didn’t know was that metallurgy related failure would be unlikely at this juncture, though it kinda makes sense.  
I’ll be sampling for a UOA before running in for a bit my occasional pre-change 1/2 quart MM oil- another part of my routine.   I know the MM may be controversial or snake oil, but I like the smell!  My thinking is it may get goo and boogers in solution to be filtered out and dumped.  Well, probably not goo and boogers, but I have no idea what be accumulating there on the inside.

      Yes, you must have seen my thread on the Blazer. HOT GARBAGE, but I love them anyway. I'm convinced every car guy has a soft sport for an S/T series somewheres. Probably even a Panther too, if I'm being an honest car guy. That doesn't mean they aren't junk. And they definitely don't get better with age. I sometimes play with old cars, but that's by choice. I don't rely on them and they aren't my everyday fleet.   Derek plays the common man on Youtube and that's no doubt where he started. Now he has Youtube money (and Motortrend, etc). You think his crews and his wife ride around in old beaters when they're chasing him and his wrecks across the country? No he's got newer and nicer stuff for that, you'll see glimpses of it in the footage.

      You refuse to own anything made in this century yet you reportedly own... a 2007 Silverado, which is now almost 20 years old. The dissonance.... turn up your hearing aid?   You clearly don't understand the government contracting process, brother. We send people to die on front lines, keep the public safe, and make people's husbands, wives, children enter burning buildings with equipment from .....wait for it.....   ...the lowest bidder....   Just because something is used for a long time doesn't mean it's good. But it might be cheap and plentiful.   Please, continue to whine about new trucks in a thread dedicated to new trucks, which you've said you'll never own. We get it. Go tell everyone how you're stuck in time on a Panther forum. I mean, Jesus, an 86 isn't even one of the good Panthers.

      It really is comical when people don’t agree or see the reason some people prefer the older vehicles. They become condescending. All the while they may be busting their knuckles on old vehicles. I have found memories of swapping out engines in my old GM cars in a weekend without much hassle. Unlike today. One wrong move a computer will shut you down. Even on something as easy as a brake job. There’s a pretty comical YouTuber called the car wizard. A garage owner who puts it all in perspective. Another Vicegrip garage that’s shows just how tough the old stuff is.

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.
