2017 6.4 4x4. 105 K miles.
Been using PUP,0w40, at first, changed to RL 0w40 at 40K. RP filters,and Bio Lubegaurd.
I have done 18 oil changes, last at 104K.
Blackstone reports, were always great, last one was at 85K.
Now out of warranty,at 90K.
CEL came on, not flashing, running a little rough at idle, some solid ticking on the left bank. pulled code, P301 misfire.
It was running fine until yesterday. Had to pass a couple of semi trucks, at higher RPMS, went to the store, in the parking lot, heard the ticking. CEL on. Drove 20 miles back to the shop I use, taking it easy.
Best hope, at the mechanics that I use, might be lifters, maybe cam, depending on how much metal contamination, otherwise looking at a re-manufactured long block. or rebuild. Total bummer.
The truck was flawless to this point, no warning signs.

That sucks man. How often where your oil change intervals? Sounds like roughly 5k?

I'm completely spit-balling here...if your UOA reports were coming back good...could it be a broken valve spring? I don't know how common those are with the HD engines, but I do know it's not unheard of.

stock 5.7 with 6.4l cam and MDS delete
easiest way to see if its a lifter or a spring is to pull the valve cover and turn the engine over by hand. watch for the rise and fall of the valves on the opposing cylinder

Sorry to hear that man, not only for your pocketbook but also what that might mean for the rest of us who were counting on Redline and friends to carry us through.

Did you post your UOA's in the blackstone thread?

Please keep us updated!

Totally stinks man. I'll be following along to see how this works out for you. Best of luck. From what I've read on here, if you rebuild, going with non mds hell cat lifters is the way to go. Nope you caught it quick enough you can just do cam and lifters.

I'd change oil and filter again just on a long shot, but maybe some debris is in oil locking a roller/rollers. When plug is out wash the bottom of pan with a clean 1/2 quart of oil. Some junk might have loosened from detergent in oil and be effecting rollers.

Man, that is a terrible week. Hang in there brother! I'm looking forward to your update and hopefully just cam and lifters.

Did you go with stock parts or the hellcat / mds delete stuff? Hellcst stuff would require a custom tune I believe, but i also believe or model year trucks (2017) was the last that you dont need a special cable to unlock the ecm. Good luck

Next time, try this.
Boot in safe mode

Run Hijackthis
Run Malwarebytes Antimalware
run Advance System Care or McGlarry Utilites

If those steps don't fix it, then your going to need someone to lay their hands on it.
Cna do=wnload those three programs through Cnet Links, after a simple google search

If you got to do clean wipe, zero out the hard drive, I still prefer GWscan.
Then use this site for re-installing a ton of the normal apps

Update after repair: my mechanic found#1 MDS lifter internal lifter stuck, push rod banging the end, was the tapping noise. The roller end was not flattened or scored. The heads removed , all lifters replaced, OEM Mopar, lifter guide kit.
Cam inspected, oil filter cut opened, drained oil also inspected, no metal found, internals were spotless. New head bolts and gaskets kit. Also had new spark plugs and boots since it was there, coolant replaced. RL 0w40 oil and filter.
$1500.00 labor. Parts and supplies $2986.76.
Haz mat, tax, etc, TOTAL:$4680.42
This 6.4 ALWAYS had a slight tick since it was new on the left bank, bugged me. Ram dealer said it was normal. I have been using PUP 0w40, first 40 K, then RL 0w40 plus Biotech Lubegaurd to now at 105K, Royal Purple 10-48 oil filters. I will continue with same.

When the P301 code and check engine came on two weeks ago , I limped 20 miles home. I didn't drive it at all. Maybe it saved me . Time will tell.
Will probably do a oci in a few hundred miles and get a Black stone report. I had done several oil analysis, till about 100K all were great.

It now is has less ticking than it was new.

It's amazing these damned Dealers are still dishonest after 20 years of well-known lifter issues ticking. Ticking is NOT NORMAL. It is a design defect. They should be ashamed of it. But they're not.

I'm glad you got your HEMI back up and running and ready for another 100k miles.

Imo, I'd move up to the larger Royal Purple 20-820 if it'll fit or the Royal Purple 20-500. That RP 10-48 is less in oil filtration, but that would be what I would do after lifter/cam,etc. replacement.

Hammer down and Happy Motoring.

Glad you got it sorted.

IMO, best to replace all as you did since already torn down. Sucks to part with the $$$, Good that no damage to cam, and no metal in system.

You had one hell of a rough patch there, sorry for your loss. Hope your other issues get resolved too.

Wishing you many trouble-free miles.

Certainly that roller seizure is the precursor to catostophic failure. You did great by hearing it and stopping use - would have starting pitting the roller and wiping the cam lobe.

The question on the Forum has always been what is causing the roller to seize? Failed engines have been tested and documented in this Forum, showing full hardness for the other lifter roller and cam surfaces.

Yes, the needle bearings in the rollers themselves could be defective, but you would think we would see more failures. My best educated conjecture remains it's marginal oil to the needle bearings, with some failing faster than others. Exacerbated by high cam centerline (no oil splash upward) and poor drainage from cockeyed Hemi lifter bores.

The fact Forum Members have stopped early ticking by changing oil and filter to superoil and superfilter is smoking gun evidence.

what you state is 100% accurate, however the OP said his lifter stuck internally, the roller end was fine in this case. I think he just got unlucky, although on occasion I get lifter tap on a cold start after a short run just to move the truck in and out of my garage to get other items out.

To the point that I now let it run a little longer when I move it back in and rev it to 2k rpm and hold it there until I see full oil pressure for a minute, then I let it idle a few seconds and shut it down.

That seems to have helped stop that cold lifter tap a significant amount.
