See attached, sounds like the "AC" & "AD" versions of the lifters got larger needle bearings.

Has anybody had or heard of lifter failures on 2018, 2019, 2020.

Thinking the lifter rollers with the enlarged needle bearings were fully implemented by 2018 (possibly 2017 not sure).

Not sure but thinking implementation of the Lifters with the larger needle bearings started sometime mid year 2016.

With 2017 maybe being the first year of full implementation.

I think this guy may not realize lubrication for the cam also comes from around the lifter rollers in route to the cam?? Or maybe I just dont understand.

there were some other posts that touched on that - there are indeed oil galleries @ the lifter bore that would both lubricate the lifter bore, the roller tip and bearings and the lobe of the cam.

the video link in post #4 - that guy wasn't that familiar with these engines. if he'd done a more close up exam of the block, he would have seen that. - instead he made the supposition that it lacked oil galleries and was a bad design and then goes on to mention the cam is up too high in the block for splash lubrication. (hint: its not the 1930s any more for engine design)

Wow, that's a significant change. Wonder if it fixes the problem and I wish mine had it. I bought mine early September 2016 but I doubt it has the new lifters.

Ya id agree with you about the guy not knowing crap. Splash lubrication is out, no one manufacturers that way anymore. Leads to air in the oil and air doesnt lubricate. This is why they separate the oil from the engine with the windage tray now. Took a page from the race car guys.
Interesting they made the roller bearings bigger. Been looking at lifters for the cam upgrade. Gives another option to think about.

Does it financially make any sense to perform preventative maintenance by installing these newer lifters in pre 2017 hemis though?

To just go in and change the lifters and nothing else, no.
If your changing the cam or have the heads already off, then i can see it justifiable. For me, i am changing the cam out, upgrading springs and rockers.

Not sure if anyone with a +2017 posted here with a lifter failure. I do remember one member with a 2016 that reported his lifter crapped out.

Although there was this member with a 2018 RT that complained of lifter tap.

I've got the Chrysler Lifetime warranty on my '16 SP.

I use the correct oil, change it per the factory maintenance schedule, and if and when the 392 starts "eating itself," I'll pay the $100 deductable and get the latest lifters that FCA has to offer.
I didnt know the lifetime warranty was still offered in 2016.

Wonder if there is a way to go in the engine with a small 5mm bore camera to inspect the roller bearings? I guess on could take the timing cover and cam out but I would worry that a lifter may drop if you wait too long or accidentally hit a lifter with the camera. All I know is when I swapped in the 6.2 cam my 5.7 lobes looked pristine...still would like to know which rollers I have but I bet it is the smaller needles as I have a 2015. :confused:

Took delivery of my ordered '16 SP on 10/31/15.

Shorty afterwards, 60 or so days, FCA dropped having SRT powered cars on the Lifetime option.

I'm guessing not a ton of '16's with the Lifetime Warranty.
Dang. That means that I could have had it too for my '16. I'm just surprised the dealer didn't try to sell it to me at the time since that's usually what they would try to do if insurance was available.

They started the usual pitch and I told them to save their breath.

I knew what price I would pay, and told them that I was going to get it somewhere. They met the price and a done deal.

If you don't mind disclosing, what cost did you end up shelling out for the lifetime warranty itself? And is it just powertrain or is it full bumper to bumper?

It's the bumper to bumper, No time or mileage, $100 deductable.

Paid $3100. If the electric steering rack goes out like some '15+ are now starting to do, I'll be "even."
