Lifter failure!

[mdc1990zr1]

Have a 2021 Ram Truck with 985 miles.
lifters are clacking away!!
Dealer told me it’s common.
Have to wait for complete failure??
Last RAM truck.
Stick with my old MOPARS made here with USA METAL!!!
340/383/426/440 BEST MOPAR MOTORS EVER!! OK I will throw in the weak 318

Just change the oil. Keep the oil filter in place and change the oil. I did that a few times and my lifter symphony went away. I have come to the conclusion that it is the newer oils breaking down in our Hemi motors sooner than anyone wants to admit.
I used PUP 5W20 as recommended and sometimes the lifter singing would start before 2000 miles were put on the oil change. PUP 5W30 would go a little longer, but would never reach 3000 miles on the oil change. Listening to the people on this forum, I have done 50:50 mix of PUP 5W30 and Red Line 5W30 or QSUD 5W30 and Red Line 5W30 and either a Royal Purple or Mobil 1 oil filter. I change the oil between 2500 and 3000 miles and leave the filter on for 5000-6000 miles. Never a chirp since using this stragagy, even when the truck sits for a week or two.
The reason I do the shorter OCI is because of the grit and contaminants that accumulate in the oil. The oil may be able to go farther, but it is still loading up with contaminants whether it is synthetic or not. There are too many tight clearances in the Hemi from the bearings in the lifters and the screens in the MDS solenoids. I believe any contaminant that is large enough to slip through a cheaper filter may get caught in these tighter tolerances and help with the lifter/cam siezure.
Bought with 16,000 miles and now have 36,000 quiet miles.

Hmmmm... SN+ and SP oils have less antiwear? Despite supposedly having to be completely backwards compatible with SN?
This happened on the diesel side with the new CK-4 low SAPS emissions oils. Rotella had to reblend.

I know this will sound a little crazy. I had an issue with a Ford Taurus with a frozen lifter. I took a quart of oil out and put a can of Sea Foam in when the engine was hot. Kicked the idle up a couple of hundred rpm. I let it run for about 10 minutes. It completely freed up. Drained and replaced fresh oil.
It’s worth a try.

I feel your concern, also have a 2017 with 185000 miles. Hemi tick has been there for the last 85000 miles on mine. Dealer says it's normal and it's just a bad design....I used Ultra platinum 5W20 with a Mobil 1 filter up to about 165000 then switched to Redline 5W20. The extra Moly in the Redline seemed to quiet her down but it's still there. With all the highway driving, I usually change around 10k.
I also have a full extended warranty up to 220k which I might have to use someday soon.
Good Luck with yours.....

Dont know if it helps but I run Rislone every other oil change with Valvoline and a good filter. I go about 7-8000 between changes and I rarely get any tick at 60000 miles. Mine is a 2017.

Motorcraft blends boast that they use cj4 level antiwear

I got into this when the boy bought an old Ford with Navistar requiring the Ford high antiwear oil spec for HEUI engines. Shell Rotella dropped it with their 1st CK-4 diesel oil neglecting all the old heaps still in service. There was a big hubbub over it. They reformulated and added the Ford spec.
I smell the same situation with this LSPI and high fuel economy spec SP.
Damn EPA has no more real mission so is after minutiae regulation to remain employed without purpose.

the original poster was playing with the towing mode... very bad idea... USE THE RECOMMENDED OIL also fools... you guys are just asking for failure...

Who the F plays with your towing mode all the time? Its like a scab... stop picking at it, change your oil, i know idiots like Uncle Tony said oh its a fatal flaw but he doesnt know jack about modern engines... change the oil at 5k, use good oil and a good filter...

If only it were that easy. I do agree with you on tow haul mode but the fact is changing your oil with the recomended oil at 5k intervals just dont cut it for alot pf folks here

My 2 cents here. I liked Ford cars, and Dodge Trucks. My preference.
I did buy a 69 Mustang Fastback for nothing ( it was free to tow away, in 1979 ).
My first Dodge Truck was a 76 1500 Club Cab, slant six, 3 on the tree.

Anyways, I spent over 2 years researching what to buy for a truck and settled on a 2018 2500 Cummins, used, with 91000 km. Before that I bought a 95 1500 Club Cab 6 1/2 ft box, with the baffed 318.

Now, Chrysler has built a ton of amazing machines, and I believer the 318 is one of those engines will run forever, like the slant six.

Somehow, they screwed the pooch on the new Hemi's. I would have loved to own a HEMI...

I remember going a test drive in a 69 Roadrunner, 426 Hemi, roughly 3 years old. It had a aftermarket cam and clutch, and I watched the owner lay rubber at 95 mph when he Power Shifted into 4th gear. I was sitting in the rear seat, and I could feel the tire spin.

This forums is chock full of bad stories, and threads about the new Hemi's failing. People are second guessing themselves about oil changes, filters, etc etc etc... barf....

I bought a Cummins Turbo Diesel... It may not be as fast as a Hemi, it may be a lot less fast, but, they have a reputation for Reliable. Chrysler messed up with this design, end of story... Some get lucky, some lose out.

Wish I could say I owned a HEMI... honestly... I understand the original Hemi engines ran like a bag of dirt until they warmed up, who cares... I remember solid rubber ( both rear wheels ), 1st gear until 4th gear, and then roughly 100 ft of rubber from both rear tires, when we shifted gears at 95 mph. Eventually it was only 1 rear wheel, but at that point it was over 100 mph. Who cares... rubber from any tire at over 100 mph...

The new Chryco cars are amazing, but, they are flawed. Buy a V6 and put a supercharger on it. I followed a thread on here about that, and it worked.

Apologies to anyone I offended.

You made the right choice. I want a cummins bad. Wanted one before but i already had a 12 valve so i went to the hemi

thats funny. i sold my cummins to buy my 6.4 hemi. no way i would go back either!

I I’m impressed with the engine’s performance. Tows my trailer over the mountains in WA like nothings behind me. I sometimes look back to see if it’s still there.
With that said, I don’t like the temperature of the oil. I will only run synthetic oil. I overhauled multiple turbines on commercial jets. They only use synthetic oil.The temps are extremely hot especially in the south summer months.You never see any bearing with carbon buildup. I do believe that running synthetic oil with a boron additive would keep any lifter bearing lubricated enough from loosing it’s oil barrier and failing.
Just my opinion backed by many years of experience.

 

[NOV87]

the original poster was playing with the towing mode... very bad idea... USE THE RECOMMENDED OIL also fools... you guys are just asking for failure...

Use of tow/haul is recommended by the manufacturer, if driving through hilly areas. Some people use it 100% of the time with no adverse effects. It's in the owners manual too. Just an FYI... Also, 5w30 oil is perfectly OK to use, per the same manual.

this is first truck with an oil temp gauge. so i have no idea what others may have been. i see 245 -250 climbing some grades with my rv. cools right down when i get over the top. but i dont back off the power either.

What are you talking about i never stated anything about playing with any towing mode....i don't even tow anything.
I simply stated i deactivate the MDS....

Also the truck has been run on PUP 5w20 majority of its miles until recently i switched to redline because im sick of hearing the ****** knocking from the design flaw of these engines.

This lifter/cam failure is crap. Ram engineers have known about this problem for a decade and yet it keeps happening. This crap is why people hate on Dodge.

This lifter/cam failure is crap. Ram engineers have known about this problem for a decade and yet it keeps happening. This crap is why people hate on Dodge.

The engineers did their job, so did the materials engineers. The problem was the accounting department that decided to cut costs on the cam and lifters. Well, they didn't specifically "cheapened" the cam and lifters, it was more something along the lines of squeezing their suppliers to manufacture them for less money. I believe that in an effort to save money, on the supplier's part, there are certain quality control aspects that are being ignored. This means that even parts that aren't supposed to make the cut are finding their way into Hemis, which isn't good. In an effort to avoid issues, and as extra insurance, I am now running Red Line 5W-30. So far, I like it.

@LuFc92 - did you run your truck for a while without disabling MDS? Did that change anything? For example, I got noise on the passenger side that's either the catalytic converter or something loose in the exhaust system. I have that noise hot and cold, it doesn't matter. The only other thing I can recommend is to run a Rolay Purple 20-820 oil filter, or AMSOIL EAO11 (they are the same). Oh, and ignore the trolls. I saw the message earlier left by someone who told you not to use tow-haul mode and some other stuff. Once in a while, we get trolls around here. I even caused one out to the point that I got a two-week "vacation" because it's a rule violation to do so. From now on, I just hit the "ignore" button and move on.
