Love your videos man!! I have a 2014 grand cherokee with 5.7, what's your opinion on the idea that running a thicker oil (instead of the 5w-20) will help prevent the lifter failure tick?

You've got quite a few excellent observations, and as a powertrain engineer that daily drives a high mileage Hemi ('08 300 6.1L with 110k), I've been looking into prolonging its life. As some people have stated, vehicles with VVT and lots of idle hours (police Chargers, fleet Rams, etc) are the most commonly afflicted with lifter problems, but no Hemi is immune. Looking at the factory PCM tunes for the common Hemis, they tend to target a 500-550 RPM hot idle speed with 5W-20 oil. This is done to ensure the lowest emissions in these bread-and-butter engines. Meanwhile in non-MDS Hemis, they target a 700-725 RPM idle and mandate a 0W-40 Synthetic oil, and SRT engineers put out a TSB saying 15W-50 Synthetic was okay in warmer climates (TSB 09-011-06). As you can imagine, low emissions are not as much of a priority for these low production SRT and manual trans vehicles, so the engineers can recommend what the engine actually needs. So if you wanted to improve longevity, I'd start with the easiest thing: tuning in a higher idle speed for more oil pressure, and using thicker synthetic oil. And for more in-depth hardware changes, ditching the solenoids like you said and possibly switching to the high-volume SRT or even Melling oil pumps. I'm not sure if it's wise to use non-MDS lifters on an MDS cam. Typically, a deactivating lifter collapses faster/further than a non-deactivating lifter. To compensate for this, a deac cam lobe will have an additional 4-7° duration at 0.050" tappet lift, sometimes 60° or more additional duration at 0.006" tappet lift, and an additional 0.25 mm of valve lift. I'd imagine using the same style lifters on all cylinders with an MDS cam would put the engine out of balance with half the cylinders making more power than the other half. But it may not be a big deal. Sorry to put an essay in your youtube video lol

@@ReignitedAuto Absolutely, go right ahead. The idle speeds I posted are sourced from factory stock PCM calibrations read with HP Tuners, and the MDS camshaft numbers are based on GM Gen III - V small blocks with DoD. I haven't seen any cam doctor results from Hemi cams, but I'd be surprised if they're super different. Fun fact about GM's cylinder deac: every version of it turns off cylinders 1, 4, 6, & 7 except the new Corvette's LT2. The LT2 deactivates cylinders 2, 3, 5, & 8. Makes you wonder if there's some NVH from DoD that changes when the engine moves from in front of the cabin to behind.

What happens if instead of ditching the solenoids, you deactivate the solenoids by limiting the gear shift to the 7th gear instead of lettung it go all the way to the 8th? Any negative effect on the engine itself or the transmission?

My 2012 lifters destroyed the shaft. 8,100 dollars for the new engine

Thank you for this, as many others have said, you did a better job going through this subject than all the other videos I have watched. A lot of the others almost seem like they are trying to freak us out, like the evening news with scare tactics. I am a long time ACVW guy but recently bought a high mileage 06 Charger R/T. All the Hemi chatter on this subject really freaked me out to a point that I was considering doing a major teardown just to eliminate the MDF lifters and solenoids and doing a tuner delete on the system. I really can't afford to replace or rebuild an engine, so I thought this was a good option. But you have eased my mind quite a bit, especially with your number that you threw out that less than 5% of them have an issue, most of them being fleet vehicles or people that sit in NYC traffic. I do not sit in traffic, I drive 55 mph for 40 minutes to and from work every day and I run good oil and change it on time. Thanks again.

Hi. I thank you for your time in researching this potential issue! We have a 2006 300c SRT-8. The 6.1 has almost 130.000 miles on it!. At 67,000 miles, we had a oil pump failure! It always have mobile 1. 0-40w in it. We Put a melling pump 10432 select. With stock pressure rated spring in it. Up to the pump starting to fail. This 6.1 was a little noisy on cold start from day one, for my taste. Being a Dodge Cummins fantastic. That started in 1990. I changed from the mobile1 0-w40, To Rotella T-6 0-40w.WOW! No!! Lifter tick! And no main bearing knock or gargel is what we call it here in TEXAS, don't let your local part store tell you that Rotella T-6 is not made in 0-40w! Put a vacuum oil canister on your gen3 or gen4 HEMI too. I was shocked how much oil was in it after one thousand miles! There was 5-6 oz's in it. Reminder! If you're Hemi has piston oil squirters! Check your vacuum oil canister about every 500. Miles or so. I know people are going to say, That's a Diesel oil!! All the chemicals or additives that are needed for flat tappet Cam in a Cummins to live. And only need adjusted every 100,000-150,000 miles!! By the way. My daily drivers is a 2004.5 DODGE 3/4 4x4. A 5.9 Cummins triple compound Bullseye 366/71mm turbocharged, twin Cp3 12mm pumps.For a very short list. Runs 10.20's @ 132.59. And the Rotella T-6 0-40w. Is all this truck has ever seen! O Yeah?

I just bought a 1200 mile 2010 Chally auto and have been told if I drive it in Autostick the MDS won’t activate…therefore NOT jolting the timing chain and not having to worry about breaking the plastic factory tensioner. But now u have me re-thinking this because with the MDS off I’m not ever getting the better lubrication to the lifters and bores. Hmmmmm…. There is a recall available on my car for the timing chain tensioner upgrade (to aluminum) but I’m hesitant to open up the front of the motor for this and create leaks, as this car is basically brand new and SUPER CLEAN under there!

As for the oil: I run 5w30 redline. I have no ticks and I have no CEL, though the main reason I choose to run 5w30 is because of the pcv design. Before switching to 5w30, I had to dump my catch can every 500-750 miles, after switching to 5w30 I'm at 2000 miles and the bottom of my catch can is filled. So like 1/8th of my catch can at the most. That alone was a huge benefit. Another thing i did while cleaning out my intake manifold was unplugging the solenoids for cylinder deactivation, that did throw a cel, but a tune got rid of that cel for me and it makes me more comfortable as I believe cylinder deactivation is the direct cause of the lifter problem in these hemis.

Your videos have cleared up so much and pointed me with knowledgeable info and in the right directions. Everyone thinks they know things and i almost listened. After 210k of abuse and 20k miles between oil changes just top off i only need to replace pistons. All bearings are perfect, im obviously still replacing everything i have some upgrades but i am basically building it like your 300. Im keeping the mds i had a solenoid go a year ago and turned off the mds and now replacing the solenoids. I have so much gunk in my intake and cai, so bought a better catch can and will have it on a fresh build instead of installation at 140k. These motors are great i beat this thing, beat charger rts, srt8 can pull away after 40mph and it goes through anything.

Its a super clean jeep i get compliments everywhere and now ill get even more.

Love this explanation. First time Ram owner but lifelong car enthusiast. So I obviously research the crap out of things like this. What I couldn't wrap my head around is the only 5% failure. Mostly due to me following a ton of fb pages for the 4th gen Ram, and it seemed like every other member has had a lifter failure. So it seems like 5% is pretty low compared to what I see just on fb enthusiasts pages, where we generally overmaintain our vehicles. But if your theory is correct, this would make sense . I would say that 80-90% of members turn off the mds manually with the gear selector, myself included because we hate the sound and are under the assumption that it doesn't harm, or helps with the lifter issue. So this whole time, while trying to prevent the issue, we have been doing the opposite and starving the lifter. This would actually make a lot of sense

I would really be curious to know how many owners continue to properly maintain their vehicles after the warranty expires. Newer vehicles are plagued by problems related to poor maintenance. Theses newer vehicles especially rely on a minimum oil pressure or they self destruct; meaning as they age oil changes become much more important. These 5.7 l msd engines must run on synthetic oil with a maximum of 5000 miles between oil changes Chrysler says maximum of 10,000 which I would not trust (the change oil light will usually come on much sooner than that).

@joebobbrown3835

Жыл бұрын

5% failure rate is probably only under warranty period. These lifter cam failures are extremely high just over 100k miles. Engines today with synthetic oil, fuel injection, computerized engine monitoring and regulating should get a minimum of 300k miles before catastrophic engine failure occurs. The 5.7 hemi engine will not do that and I know because I am about to have my second lifter/camshaft failure on my 2014 Ram 1500 5.7 hemi engine with 255K miles. First failure was at 154K and you couldn't get lifters because they had backorders of more than 20,000 sets. That's when you know there is a problem. I believe it is an oiling problem as well as a camshaft and lifter specification problem.

@derekv8534

Жыл бұрын

I’ll estimate maybe 10% of HEMI owners are “enthusiasts” enough to regular FB communities, with no data other than the people I’ve encountered over the years. So if half of them have lifter issues then the 5% is pretty accurate. Also, it’s estimated only half of vehicles produced are still on the road beyond 120k miles, so there is that variable as well.

Great video, I just got done watching the uncle Tony one also. I've got a 5.7 in the shop it's a repeat from one of my customers. She had the original cam go out due to lifter failure at 160k, I put in a low mileage engine that had 25k on it. It lasted to the 170k mile mark and is starting to have the same failure. I think this is where Tony hit it on the head with the lack of oil over a long period of wear. Unlike other engines that the lifters/cam ran forever. I went to a tech school in the 80's so I spent a lot of time on how things are built. I get lost on the forums with people talking about oil and you mentioned also about the engineers. The funny part on the oil between 5/20 and 5/30 is we start talking about CAFE and CARB standards. We all talk about going down rabbit holes and I see people talking about only 5/20 but when you read every single owners manual under what oil they will all show using 5/30 under severe heat conditions and when I used to work on fleet vehicles. All fleets used to only run 5/30 including all of the rental car fleets in America. I hear all the stories about dealerships saying wrong viscosity, but i've never seen one in 30 years, but i'm a single mechanic and dealerships are seeing a much larger volume than my little shop does. keep putting up videos it was very informative.

I have no idea if this helps your theory but I will offer this information on my situation- Engine 1- I bought the truck used with 111k miles, how it was treated prior I have no clue.( In my possession I take good care and maintain the vehicle as it should be, 3500-5000 miles between oil changes keep a good eye on all fluids and temperatures frequently etc..) at 148k the roller lifter "shell/wheel" broke and the needle bearings escaped to the oil pan. The noise was something between a lifter tap and a rod knock. Little louder than a tap not quite a knock, very apparent mechanical contact. The specific lifter was a non-mds type (no holes) it was the very first one from the front of the engine on the passenger side. Engine 2- came out of a totaled/salvage 2015 ram 1500 with 54k on the dash. The non mds type lifer on the driver side , 4th from the front failed when my odometer was at 266,500 (266,500-148,000=118,500 I put on it + the 54k it had already= 172,500 total miles on the engine) the noise was the same in this instance, but when examined the shell/wheel hadn't broke or released any needle bearings but instead kind of crammed down into itself and jammed up. In both instances I did not get a misfire, I pulled them both out and tore them apart to find a badly gouged cam lobe though. The first one I gave in for a core fee refund. on the most recent one I learned my lesson and am rebuilding #2 for the inevitable failure of #3 ( pulled from a 2013 with 115k miles on it already) . Here's the thing, an American V8 Truck engine should last until 300k if maintained properly, that's not a question. they did it in the past, I had an 01 silverado 4.8l 5 speed that I dogged the $h!+ out of for years it was my first truck and I raced it at every light and was known to pull thousands of pounds more than it was rated for on a regular basis (so heavy the problem was stopping ) I parted that thing out at 350k with the original engine and transmission STILL working in it not an issue in the world with it ( I didn't have the title and needed to get rid of it for a back seat after my daughter arrived) people calling for a recall is ignorance because it's not a safety issue but it is flat out despicable and complete horse $h!+

Awesome in depth review of this issue 💪

Great video sir. MOST videos don't go into depth on HOW a system works. You have and that's super valuable. I have a Hemi on a RAM 1500 and #7 is deactivated. I'm trying to figure out what's causing this. The system keeps burning up the coil on #7 and the time it takes keeps getting shorter and shorter. I'm also getting an overvoltage code. I'm trying to figure out what sends the voltage to the coil to see if that part has failed, etc. This most important fact about all "engine stuff" was left out. That is that the US government and the EPA work endlessly to make sure Americans have the most INEFFICIENT engines the world has ever seen. They devise mechanical systems like the one in this video to give consumers the illusion that they will get better fuel economy, when in fact the system doesn't even need to exist. We have had the technology for DECADES to make an engine equal size to this Hemi get 100 mph no problem. But, they like our money... and nothing else.

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!!!

Hi, I have been a FCA mechanic and shop foreman for 26 years , seen and done DOZENS of lifter/cam repairs ....your video is very informative . I currently have a 2013 ram with msd with no issues at 170000 k. I also have a 5.7l with stand alone fuel injection in a 1946 international truck , with the mds disabled and holes plugged . I would like to add my 2 cents worth.... out of the DOZENS of cam /lifters i have done , probably at least 90 % were on left bank cyl 1,3,5,7. ????? of course there were some on right side , very few . in fact just today I picked up a core 6.4L (292 ) BGE out of a 3500 that I am going to build for my International, and it also have # 7 cyl cam issue.

What oil do you use? I use 5W-30 Full synthetic Mobil 1. I have 255 idle hours and 64,000 miles on it. I have a manifold tick but unsure of what the correct fix would be. Grade 8 bolts, new manifold?

As a tech who owns a 05 300c awd 5.7 without mds i don't worry too much as ill repair the engine. But this is very informative. And thank you, when I cam my engine soon ill for sure be upgrading to the hellcat lifters

Your videos are good dude. Super fair assessments. To the point in general. Rock n roll doggy dog. Keep er up. You’re in your flow and helping people out. Bomb bomb good stuff.

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.

Love the video. Had a 2014 hemi with lifter failure. Cost me $3800. Was told by a couple other mechanics afterwards to run it in 8cyl constantly to avoid the issue. That it’s the mds system that causes the issue. After watching your video now I’m afraid I’m damaging it by not letting it go into mds mode. You make a lot of sense for sure.

Interesting idea you presented. I was told by people that race new Gen Hemis (1 guy worked for SRT for several yrs) that the fix on ALL 5.7s, and 6.1s that DO NOT have MDS, is to use the updated HellCat ( also used in 392s) lifter. They are stronger and have been redesigned where the roller does not fail. They say to continue to use a top quality synthetic oil, changed at about 4k. For those with MDS, there is no update at this time.

That's an interesting angle on the issue, thanks!

Another thing to check when the cam/lifter is replaced is to change the VVT solenoid. There are screens in there that catch the stuff from the cam/lifter destruction and will make their own ticking noise. The screens also get brittle and come apart on their own.

Conventional 5w-20 for first 76k miles with OEM oil filter. Full synthetic high mileage oil since. Have not had any problems with cams or lifters (fingers crossed). However, I did have the dealer replace broken exhaust manifold bolts at 64k miles, and taking it to the local muffler shop tomorrow to replace the OEM manifold with new shorty headers (broken rear bolts again!).

My daily driver, done lots of towing, hauling heavy loads in the box, and I have always tried to get it into 4cyl as often as possible. At only 3,000km it started to "tick" at idle when below minus 20 celcius (Calgary Canada), swapped to full synthetic, instant fix. At around the 30,000km service I used regular oil, within 2,000km it ticked again, so drianed and refilled with full synthetic, noise stopped. Been using full synthetic ever since, no problem. I am a Technician of 40 years, thanks for the indepth demo of he system, as I understood the MDS concept, but never having worked on these didn't know the full operation.

I've been driving my 2012 Ram with the MDS shut off for about 200,000 miles. I haven't had any lifter issues. I disable the MDS simply by pressing the gear limit button on the shift lever. I've been doing this for years because when the truck goes into MDS the rattling/ticking noise the engine makes drives me up the wall, and I'm too cheap to delete the MDS.... lol. I even noticed an improvement in gas mileage after I started doing this by a couple miles per gallon. I also have only ran Mobile one full synthetic oil since the day I bought the truck new in 2012. 240,000+ miles and runs like a champ.

Thank you for your explanation, very good. Just for everyone knows I have a 2018 lifter issue with 56000 miles and it happened a few miles after a late replacement, I read a metallurgist analysis in the roller and they couldn’t find any pitting on it was mean it have good lubrication but the oil was not sticking to it so the added properties to the oil were lost so I do really recommend not to wait until your car tell you to replace the oil, oil should be replaced earlier than every 10000 miles. Just giving my opinion and experience with this issue.

This is the best explanation I have seen ..... Thank You

Nice explanation! I'm an old, out of practice A&P mech and this system is definitely genius! I also believe the problem lies in your lack of lubrication theory.

If not that lack of oil, what else would cause the excessive wear on the mds roller bearings and the mds cam lobes only? Perhaps it's a simple as the mds lifter being allowed to collapse and not function as a solid, sliding lifter throwing oil around? Or maybe my thinking is off. Wouldn't be the first time...

You folliwed the trail of clues in true professional form, and seem to have found the issue, or at least a few contributing factors, although I personally think there's another cause of lifter roller failure if I am correct here. Here goes: I've always had the impression that the lifters were the part of the lubrication system that was similar to the weight on a purge valve in a steam boiler system, and is designed to trap oil and keep it until it reaches a speciffic pressure before the oil pressure exceeds the limit of the lifters mechanical restriction and it escapes up the puhemup tube rods, and spits on the rockers and valve stems, and is left to gravity drain back to the sump, but never actually looked into this in detail, since it seems logical. If what I've been led to believe for all these years, is true, then I think there's a chance that this holds a possible clue to the issue as well. It's a 50/50 shot, but since you've directed the lifters, and have an intimate understanding, maybe you can answer my question, but I'll probably look into it like right now.

As a FCA parts manager, and former tech this is an exemplary explanation of the lifter management system. He is absolutely correct about idle management. It seems key to livelihood of the lifters. The only commentary I may add if that the roller bearings in the lifters them selves seem to be the weak point if any. Usually that is due to poor maintenance. General Motors has the same issue. Oil changes and quality of of oil can prolong the the use of the engine significantly.

Police departments have big issues with the lifters because they idle so much. Out of a 12 hour shift, the patrol unit is prolly running/idling for around 7 hours at least and for a K-9 patrol unit, per policy, the patrol unit must stay running for the entire shift because of the dog. So it's running/idling for 10 to 12 hours a day, at least 4 days a week for at minimum 5 years. Lol so yeah, lifter issues ha. 7k idle hour

We also had to change vent valves on fuel tanks due to emissions. I JUST got done replacing my cam and lifters. The MDS lifters were the bum ones and ate the cam.

Police departments that are using the Chevy Tahoe PPVs from 2018 to 2022 are having lifter and camshaft fails at or near 10k miles because of GMs version of the fuel saving displacement system and its not just a few of them. Its A LOT of them that are failing that soon and when replaced and fixed, the lifters and or camshafts are failing again within 5k miles. Now that can't be factory issue right? Can it be that the fuel saving system is that horrible on the GMs or the material used for the lifters and camshafts are just junk? Police department maintenance policies are to not disconnect the fuel saving management system.

Good points. A couple items to consider: Did you notice that the connecting rods don't have traditional squirters to oil the opposite bore and reciprocating assembly? Maybe this also contributes to a loss of cam and lifter lube. Some of the engines have fixed block squirters, but not all of them; and those are just for the bores. The old way slings and squirts the oil in all directions. Also, you have to use the thin oil because the new engines are close bearing tolerance engines. Finally I noticed Jasper has videos where they are fixing the valve seat issue and other issues. I think the factory could make a few changes without re-tooling. Also, a video by MMX shows how defectively designed aftermarket lifters can dump the oil pressure as they move up and down. It's pretty interesting. Observations of an Engineer. Shalom
