5.7 HEMI Lifter Failure Could this FIX the lifter issue FOREVER?

Never heard of anyone throwing a code for improper oil viscosity, been using the “wrong” oil viscosity for years.

Even your comment section is full of information. I'm liking your channel😊

thank You so much for your knowledge on the MDS system. I had owned a 2007 RAM hemi and a 2018 eco-diesel. Loved them both but did not trust the eco-diesel so I sold it when it had 50k miles on it. I wish I would have known about the MDS system before I took on my 2012 RAM 1500 5.7 hemi project. Bought it from a bank repo and knew nothing about the history of the truck. It was not well taken care off. It had the hemi tick. Ran very badly. Watched many videos. I tore into it and found four lobes on the camshaft worn down damaged, one ground down so much there appeared to be no lobe. Lifters also very worn and damaged. I wanted to do the MDS delete but did not know how plus an added expense to have the PCM software changed. I was told the dealer would not even do the delete and it had to be aftermarket like Diablo. Wish now that I did it. After putting in a new camshaft, lifters, and MDS solenoids, new timing chain kit and an upgraded oil pump like you recommended, and a couple sensors and 4 new O2 sensors and a few minor non engine things, I thought I was doing pretty good. It started it and it sounded great. But I still had an O2 sensor code, a new MAP sensor code and the dreaded flashing red throttle light and a check engine light and it was in limp mode about now I was going bonkers and being a fair DYI mechanic, decided that I was going to beat this beast. Figured out the O2 issue (electrical connector and it was very difficult to reach it B1S1) and the MAP was also an electrical connector issue. So I start it up O2 sensors all read good. Now a new code popped up. Misfire in #4 cylinder. Oh crap. Took off the valve cover. Number four Intake valve was not moving at all, but the exhaust valve was working. By now I am cursing the MDS system. No way this could happen. Did not think it was the MDS solenoid because the exhaust valve was working properly. reluctantly, took off the head and verified the lifter was stuck in MDS mode. I am thinking cheap chinese parts but I used good OEM parts. I could stick a probe in the oil hole and push the little pins in and it would lock into the normal mode, however, I did not trust putting it back in the engine. I bought the front four lifter set. It has been too cold to put it back together. So this is where I am at. What a nightmare.
I thought about what you said... to do the delete lifters and plugs and just run it like that. The thought crossed my mind that the PCM might want to throw out more DTC codes because at some point it is expecting to go into MDS mode. Any how.
I asked GOOGLE AI if the upgraded oil pump could have possibly provided enough oil psi where it could have activated the Lifter??? It responded "unlikely" because the MDS solenoid would have to be activated to allow enough oil pressure to do that. I still question that it might happen. But at any rate, it would not go back into normal mode so I just relaced it. Have not finished it yet and will wait a bit for warner temps. Sorry for the long story but I thought you would appreciate this hemi sob story.

My car does this to save fuel, I find this fascinating, great video... A big fan!!!

When that system shuts down and turns back on I really don't notice a power change going over grades on the roads on the highway...

I am a over three year mechanic professionally, walked away and became a truck driver. Bought a 2020 Ford truck, had no problems with this 3.3 V6 so far. Then bought my 2014 Dodge Challenger 5.7 Hemi from a dealer used of course, first thing I had to fix was a $1600 upgrade for new stock alternator, reworked for power wire off alternator and a new battery from a Dodge dealer. Now it works fine. But after buying from a dealership that wasn't a Dodge dealer I was very discouraged. But I love my car. Also the coolant tank was really low, and I was very concerned, but after filling it I haven't had any problems so far!!!

May I ask what kind of gloves and brand name are they, please???

Mds is shit!!

I have a 2019 dodge ram Bighorn with a 57 hemi my lifters are bad and I don’t know which ones to buy off of Amazon. Can somebody help me

What a JOKE !! This video has ZERO info on fixing the gen 3 lifter tic !!!

Waist someone elses time trying to half ass explain how the big 3 & others do business !!!

Get a life !!

Is this about problem with engine.or problem with company fixing the problem with engine.

Can I Inject oil into lifter after I install cylinder head to activate mds lifters prior to starting engine

the company needs to streamline the ability to make changes so that faulty products are not continually made. The cost maybe high, find ways to fix it, its the lifter that's the problem swap in better lifters seems easy enough.

I was told that using heavier weight oil help. What are your thought? Great video

Hey i have question my hemi was rebuild with new lifters and camshaft , mds lifter on cylinder 1 failed after 8000 miles. What could cause it to fail so soon

It's way more than 5% failure rate on these lifters and cams. It may be 5% during the warranty period but it is way high just after the warranty period. When mine went out on my 2014 Ram you couldn't even get lifters for it from anyone including Dodge and they hac over 20K backorders and could not give you and estimated time for new ones to arrive. That is a major failure rate.

Here is a very small bir of data, probably so insignificant that it's far from useful BUT...while sorting out my oiling issues on my third hand 2500 with 6.4l, if I turn off the CEL. The MDS operates for a short while but the engine oil heats up more and my oil pressure drops quicker AND lower. With the CEL on the breakdown I'd slower and pressure does not fall off as much.

2022 ram power wagon 2500 6.4l and I already have the hemi tick, piece of crap, 130,000 is what I drove, REGRET!!! REGRET!!!! REGRET!!!!🖕🖕🖕that’s for for DODGE RAM

You're info and how you're helping all of us is doing a tremendous service sharing your wisdom and hard earned experience. Thank You!!

Thank you for the knowledge.... I have a 2013 Ram 1500 bighorn that I believe has a lifter failure.... I have been weighing options on how to fix it. I am in such a bad spot in my life at the moment with my mother having cancer, and work being slow, well I could list a whole bunch of things that have just put me in a streak of bad luck but we won't get into that at the moment. What I am getting at is , is it best to go with the factory OEM parts and delete the mds system or is there a better solution to the problem that you recommend and the price difference because I am trying to figure out how much money I have to come up with to perform the action. I am mechanically inclined and very comfortable with doing it myself but I am not a Mopar man. So not very familiar with the engine

Less than 5%, 🤦‍♂️yeah that sounds like the kind of luck I have. I just happen to buy the truck with that lifter problem.🤷‍♂️

I always used mobile 1 0w40 for my 6.4 never lesson lifters noise for long time, after using liquimoly 5w40 for couple miles i lesson alot noise from my engine 🙃🙃

I have a 2015 5.7 Hemi. I've had the hemi tick. Had to cam, lifters, pushrods, ext. Everything was replaced. Getting ready to do the 3rd set of push rods. Keep wearing the ends off. Everything else looks great.

Neither lifters are a solid lifter they're both hydraulic

Im lucky enough to have a 2005 grand cherokee. The engine runs fine, but the plethoria of electrical problems make it undrivable. I've spent over a year diagnosing it. Maybe its the PCM but hey they discontinued the part and all the replaced part numbers for it. I'm not trusting these shady reman companies that are charging $1200 for a used one.

5% but it happened to me. At least I could afford the dealership garage to rebuild with new cam and lifters. If I'm swerving and cursing Chrysler in rush hour traffic on 40 approaching Knoxville, that's a safety issue 😅

I have a 2003 ram 1500 4x4 5.7 hemi with 300,000 miles on it and I have run nothing but 10w30 in it
Great running little engine

I got a 04 Hemi Durango 280k went to get an oil change they put 10w30 here I am 7 days later and a tick has developed

Can I just replace the lifters if the noise just started

Good analysis. Decades ago, I sort-of MDS'ed one cylinder of my 1969 slant-six to disable a worn cylinder until I could swap in a long-block. First, I just removed the solid lifters and pushrods, but a co-worker said that would cause loss of oil pressure (untrue). Fearing that, I put the lifters back, but added weak springs w/ copper tube "pushrods" so they ran against the camshaft lobes but didn't open the valves. Turns out the slant's lifter bores have no oil ports, rather the lifters are just oiled by splash and drip.

Chevy has the same problem with their cylinder shut down. The old Magnum 5.2 and 5.9 engines didn't have cylinder shut down but their lifters didn't get a significant amount of oiling especially to the ones furthest from the oil source. They had a similar size if not smaller oil bore but the hole feeding the oil from the main galley to the lifter galley was smaller. Not a lot but enough that over time they would wear. Not suprising but also makes sense. They were hydraulic rollers so similar to the mds lifters but not solid until you got enough rpms to keep them pumped up.

I have the hemi tick and kept running the car. Question do I need to fix it or keep running the car as is? 2009, 5.7 145K miles

2015 Ram 1500 5.7L Hemi with failed lifter in cylinder 3 at 111,000 miles.

Air bag clockspring broke at about 60k miles.
Leaking third brake light and cabin vents.

Thank you for an absolutely excellent video. I could not help but wonder if the failure of the mds lifters might actually happen as the result of a broken spring inside a lifter. The result would likely be that the lifter is no longer always be rolling on the cam and instead starts hitting the cam at every rotation of the cam, and that with the roller itself on the lifter, remaining fixed in the same position, and considering that a hit would take place at every rotation of the cam, that is a lot of hits in just an hour when the engine is running, and it naturally follows that the damage exactly as we see it on a failed lifter would be inevitable.

As I think more about this possibility, it seams to me that all it would take when mds is engaged, is if the spring inside a lifter would simply become weak enough that the roller on the lifter to no longer stay in touch with the cam, and the cam would then act like a bat a ball against the roller on the lifter and the result could be the distinctive hemi tick. Also, as the roller on the lifter is being hit by the cam at every rotation, it is no longer made to roll on the cam and that would explain the lifter failure always having the side of it to the cam being worn down. I would like to know if the experts think that there is any possibility that this is accurate.

What would happen if you just unplugged the MDS solenoid? Left everything in there just unplugged the wires that tell them to open or close?

Im rebuilding a 5.7 im going with 20 50 oil

The mds makes no noticeable difference and is a lot of needless extra junk on this engine, If l wanted a 4 cylinder l would have bought a 4 cylinder l cancel it out. They should made better lifters my engine had this noise brand new the dealer told me can’t fix it if nothing is broke. Now at 115000 km the noise is getting louder,my oil changes are 5000 miles with full synthetic.

Has anyone else had a problem with the cam on ram 1500 costing a lot of money. It appears that this is a problem that jeep dodge Chrysler is aware of and has not addressed

I think I just messed up ! I’m replacing cam and lifters but my engine is not mds, and I didn’t know that was a thing 😭😭 my replacement kit came with mds lifters! And I’m almost done with my build 😭😭 am I going to have problems if I run my non mds with those MDs lifters?

Yep! Fix it FOREVER by not buying JUNK quality Stellantis GARBAGE 🗑 Lmao 😂

So basically does it to itself basically the engines own fault

I have a 2013 1500 5.7 hemi i have a lifter failed and I have torn it apart my question is I want to upgrade cam what would you recommend and gaskets what name brands do you recommend do I stay away for eBay parts

What happens with the MDS system when towing or using tow/haul mode?

right on thank you

My 2021 has this issue . Ram Rebel
😊

Question. I am looking to buy a 2018 Ram 2500 with a 5.7. Some people tell me the HD trucks don't have MDS. Others say they do. I bet you know!

Fist of all thank God and Bless you for all you do! I’m have a 2013 ram 2500 5.7 I decide to repair my camshaft and lifter my self thanks to your videos , I need directions on who to order my cam and lifters from who would you recommend? I also took your advice on getting the high flow oil pump

Does this apply to the 6.1, 6.2 and 6.4 hemi and hellcats?.

Your last statement is good but the problem is that the cylinders that have mds those lifters would only lubercate cylinders 1 4 6 and 7. So only half of that portion of the valve train would get the attention. I agree with the hellcat oil pump for more volume at idle where pressure is not as prevent.
