I have an18 year old Hemi 135,000 miles with MDS and it works fine if you follow proper service procedures
:(
Unfortunately I have to replace my cam and lifters on my 2014 300s at 171,000 miles. Started ticking at 100,000. I won’t be buying another dodge I was told go full non mds cam and lifters so I bought the whole set up with the tuner gaskets and all. 1300 just for that and caught a deal for 1600 in labor it sucks. I wanted a challenger Rt or scat but I’m going to just pass goodbye dodge. Luckily I have my Chevy Malibu as a back up with 250,000 miles never had no serious motor issues with it other than a regular tune up. As a matter of fact all the cars I’ve owned from mustang to my infamous 2004 Pontiac gtp got well over 360,000 miles never had to tear down the top of the motor
Just got a 2020 charger v8, and this feature is able to keep my mpg at 20.8 mpg with a 91 gas, not too bad for a big V8 car. To compare, my turbo 4 KIA Sorento SUV pulls in about the same MPG. V8 vs V4 SUV for the same mpg, yeah not too bad.
My 2015 Dodge Durango AWD R/T 5.7 V8 has a a ECO mode button. Willing pressing that button disable the MDS?
No you need to choose a gear for manual mode but it's still automatically shifting in manual or you can shift
It causes failure

Looks broken already
Too bad the VVT camshafts are cheap. Truly feel sorry for those shelling out thousands out of warranty to have the top end torn apart around 100k miles.
Yep I’m in the process now of a new cam and lifters after 171,000 miles on my 300s. I’m going full non mds cam lifters
I won’t be buying another
Cuando se produce la falla usualmente es con los buzos, botadores o taquetes inteligentes, o también ocurre con los solidos? Es decir, solo debería cambiar los colapsables para ahorras costos? Y que marca de buzos recomienda?
16 pushrods or what
Mi señor tengo malo un buzo o actuador hidráulico, es el del cilindro 8, pero se mueve hasta un punto fácil y luego se atasca para salir, como debo proceder para sacarlo sin dañar la camisa donde esta ubicado, será que puedo sacar el árbol de levas y sacarlo hacia adentro o es imposible
He visto videos donde les cambian todos los buzos pero quitan primero el arbol!
That thing got a hemi in it
Good for
Love a dodge ram. like a tus vídeos y suscrito
Hi one of my lister is making a noise is that why one of my spur plugs get wet i have a 2005 hemi dodge ram 1500 5.7
Your dose’t have mds only 2008 plus
I enjoy it personally. I pull 30mpg on the highway, and I love how the sound of the engine instantly changes to a V8 tone when you go past quarter throttle! I think its thrilling! Just keep your oil clean so those lifter rollers dont seize up.
You probably like watching other dudes bang your girl too🙄
👍
No explanation what so ever!
That tells me the Piston Numbers based on that 1 8 4 3 6 5 7 2 firing order demonstration that I'm familiar with. I knew which numbers are for the Pistons lmao
E co its like turning your Mds on Hemi 5.7 ? Right
this system kills off these Hemis prematurely how can anyone support this crap.. If you're on of those that bitch about fuel economy get a fucking honda or Tacoma leave the V8s alone!
Can one of the solinoids going bad cause a valve to stay open and not build compression
Yep
Why no audio?
Fuel savings wasn't worth the $5,500 to replace the engine because of this system.
please educate yourself. This was a flaw on the Hemi period... doesnt' matter if it was 5.7 or not. Doesn't matter if it was MDS-equipped or not.
@@LarryReynolds591 the flaw was the crappy lifters. period
@@LarryReynolds591 If it was a "flaw" every Hemi would be effected, when in reality, 99% of the time it is MDS 5.7s
no wonder they wipe the cams all the time. I bet those things wig out when you start hammering on the throttle. lifter goes flat at high speed? wipes cam lobe?
Yeap.
Im replace the whole engine at 108,XXX miles! Always ran full synthetic oil. Hemi is trash. Now i have to drive a truck i cant trust to justify the cost
Is there a point to this vid!?
Pure junk
Are these engine pretty reliable. Got a super great deal on a low mileage ram 1500 sport. It's my first Chrysler product as far as a trucks concerned. I've always drove ford f150 and toyota tundras so I want to try something different got tired of spending 48 to 50k on a truck. I bought this used and it had 12k miles on it so I really dont know enough about these motors weather they are reliable or not. All my friends told me that these are great trucks!
what year. early models lifters were trash and caused failure. id do a delete with cam.and lifters if you want reliability. if you want mpg then stick with it
Super reliable engines, if you have a 2009-2024 Ram Truck with the 5.7L HEMI, I would highly recommend upgrading your oil pump to a Hellcat/TRX Oil Pump to prevent oil starvation on the MDS lifters along with the rest of the engine, that way your constantly getting pressurized oil on all of the internal components at all times while driving And make sure to NOT EVER idle your HEMI for very long periods of time, this is where your lifters can fail. And make sure to ALWAYS ALWAYS ALWAYS be on time with your oil changes, and never go past 3,000 Miles, or else you will accelerate the failure.
Yep! And that explains the many thousands of Hemi owners after around 2007 losing MDS lifters that eventually destroy camshaft lobes. Our 2012 just bit the bullet a few days ago with less than 105,000 miles, but started at about 94,000 miles. And the "Hemi Tick" which Chrysler and their paid disinformation trolls will say, "Hemi tick is normal"! Such a freaking lie. And for you Mopar fans still in denial about the so-called, "rare" lifter and camshaft failure on Hemi engines, then you might want to explain to the rest of us with bad luck why there is a huge 2 to 3 month back log for lifter replacements? LOL Chrysler knows of this problem and will eventually find a solution. But they are screwing their customers into forking up the $3k to $4k repair costs and long delays. They built a high performance engine using low performance parts. While I enjoy the powerful hemi, I detest premature failure of a camshaft caused by failed lifter rollers because the MDS cuts oil pressure to allow for lifter collapse. Oil pressure expands the lifter. What a dumna$$ idea. Chrysler engineers are not too bright. My 1999 Suburban has out lasted all 3 Mopar vehicles we have owned. 1997 Srratus...lost head gasket causing oil leak at 54,000 mikes. Engine sized up. 2002 Stratus loat water pumo and timing chain at 98,000 miles despite previous pump and chain replacement 3 months prior...engine over heated without warning and destroyed the engine. And now our 2012 Hemi just lost a lifter and has likely damaged the camahaft lobe. Man I love my Chevy with nearly 300,000 miles and still going.
You must have the 2.2 litre engine in your subaru. BTW my dodge magnum rt has 160000 miles same hemi engine
Blew my 2011 challenger up at 42k miles. I didnt buy it for mpg anyways
I have a 2008 Jeep Grand Cherokee with the 5.7 MDS, odometer just rolled over 200K... no issues with my engine or this system. Works perfectly with no noticeable power drop off. Still a gas hungry SUV regardless... but that's all part of the fun of the HEMI... power!
Worse idea EVER? And the reason my family stop buying Dodge crap. Who the fuck buys a V8 for good mileage?
BUYER BEWARE: this engine will have major failure with cam and lifters because the bearings in the roller lifters are not hardened . they are gonna fail and cause the lifter to twist and wipe out the lobes on the cam.
Having the same cylinders cut on and off will give uneven ware and eventually scare a lobe.
Hola les escribo desde Caracas Venezuela tengo una oickuo dogde ram 2500 motor hemi el cual 4 cilindros no me trabajan quiero saber decido aque están desactivados cual es el motivo por la cual se desactivan sin los cilindros 1467
So turning the solenoid ON collapses the lifter? or turning it OFF collapses the lifter? I'm asking because I am in the process of putting an MDS Engine into a non MDS vehicle. and wondering if I should pull the solenoids out or just leave them disconnected?
Did you finish your trnsformayion to non MDS? I have now this problem with lifters and i think to switch of MDS.
Try putting in heavy weight oil and see what happens..... click click click... ... ...
This system is what blew my friends Chrysler not once, but twice.
Deactivation of your right foot is what saves fuel.
Still more reliable engine than cylinder deactivation on chevy
At what speed dose the msd sys kick on I heard it comes on at 20mph and faster if u drive under it stays off
Mostly rpm based under 2000rpm in high gear
I'm currently having a misfire on cylinder 2, did a compression check and its all over the place. Any idea what it could be? I've been told it could be to do with the MDS and perhaps a new set of lifters..why on earth add this kind of system to a performance engine :( its costing me a ton of money already to eliminate what the problem could be...
Probably sticky lifters and valves. Change the oil and pull the valve cover, top off with Marvel oil (maybe a little in the tank if it calls for it)
This could be caused by a loose valve seat in the cylinder head. Better pull that head and check it out before the engine is destroyed.
MDS sucks,GMs version sucks also. today you either get this bullshit or auto stop start garbage,...CAFE LAWS !
doesnt the compression and decompression of the 4 cylinders cause parasitic drag on the engine?
Minutley, but no different than the rest of the Drivelineand oil pump. The NONfiring cylinder is kept in a vacuum on the upstroke (power and compression stages) so parasitic load is on the down-stroke only (Exhaust and intake Stage) . Every moving part in an engine contributes to parasitic load.
Energy produced, is repetitious to energy absorbed. The compression that the deactivated pistons produce, is the same energy used to push them back down hence creating a cushion effect. No compression drag when deactivated. If if there was, it's too minimal to effect efficiency.
@@danielorsborn9464 yes obviously every friction point is power loss. This question was 3 years ago lol, its not a minute loss of power, its a lot. to conserve minimize fuel consumption while keeping your speed, losing 4 cylinders wont add a small amount of drag, its a lot. 4 cylinders pushing momentum through 4 dead cylinders and a drivetrain vs 8 barely pushing the drivetrain.
@@slacinace really dawg. 3 fuckin years later you wasted your time to come back and respond.....
Doesn't this system make un-even wear??!
What I just said!
Moe Leo it causes carbon buildup around the piston rings during cylinder deactivation resulting in loss of compression and oil consumption
About as usefull as ford using start stop "technology" or chevy shutting off injectors on the highway. It may prolong your fuel capabilities but causes hell on internals. They need to get rid of all pushrods and go with overhead cams. You can do so much more with variable timing when the cames are on top and theres less parts that need to move leaving much less parasitic loads
nice engine instruction
It's useless I disabled with my tuner and it's didn't change MPG. Have a 2013 Ram Sport 4WD with 8 speed it's a 5000Ib truck it needs all cylinders working not shutting down. If I was worried about mileage I wouldn't of bought. From day one average 23 MPG with or without MDS
Still has those crappy lifters. They should last longer though since they're not being used.
charlietow Very true they should but I have no issues as of yet knock on wood! !!
Haha! *knock knock* I have a Chrysler 300C in the shop right now with a failed lifter on #6... 93k on the odo.. I also have a GMC Tahoe with a #7 failed lifter. Trying to sell a cam with no DOD(GM) or MDS(Mopar) and a tune. The idea looks good on paper but isn't worth shit in the real world.
charlietow Have no issues as of yet with my tune but rest assured if I do trade before it gets screwed lol
Around 210,000 on my 07 Ram 1500 trx4. The truck runs fine but MDS is causing a light vibration and bogging. I ignored it for along time but now it'll blow a small amount of smoke when they engage all cylinders. I'm going to take it down and have a tuner shut it off. By the way I don't think I have a lifter issue yet, I can let it idle for awhile with not smoke.
Very revolutionary engineering. I have it and it saves me gas. When I need power it shuts itself off and I am going again. This coupled with an 8 gear transmission is awesome. It works.
i mean its a cool idea... but it does make your car slower for a few seconds while you wait for the oil flow, so for #racecar its kinda bad
David Allen mine can be in MDS, hit the pedal and you wouldn't even have known, it's like not even half a second and it's off. It's crazy.
@@Votlon seconds?? more like instantly
@@James28R yeah this was years ago before I was more educated, I didn’t know what the fuck I was talking about(;
I hate the MDS. I wish Dodge would just put a switch or something in it to just turn it off. I put my Ram in the +/- manual mode. It's a 5.7 Hemi, not a Prius. If I were that concerned about fuel mileage, I wouldn't have bought it.
+Phil Harris It's not just Dodge. It's to keep up with new Government mandated emissions standards. Which is also why you cannot disable it by easy option. I feel if it was Dodge's choice you would have the option to enable or disable. I mean come on! We are talking about the hell cat boys!
that's rigth same issue with my truck first time dodge no happy with it runs great sounds ......
Phil Harris. the 5.7 2500 has no MDS. now that's a True V8. but the 6.4 2500 is MDS.
I like the MDS on my 2014 RAM 1500, but I see your point and you're right. There should be an option where you can enable/disable it as one pleases.
I have 2018 5.7 hemi 8 speed, if you gointo the settings and limit it to only 6 and also drive in tow/haul full time it nver comes on, I didnt even want new truck but lady blrw a stop sign n wrecked my 03...
And this is how your tensioner and timing belt breaks on ur hemi. Disable with a tuner and enjoy ur all cylinders in ur hemi v8
bear in mind that was only from 09 to 11
09 to current. 2019 still has it.
Timing chain not belt
