I feel honored to have my Charger on one of your videos. It's incredible to see all the hard work everyone at Dave's has done to get The Green Machine back on the road. Dave, you have a customer for life. Big thanks to you and your team...and yes, I'm getting that suspension fixed 😅
That fresh engine sounds amazing. Should run you many miles. It looks to me like these guys really care about the quality of work they put out. Its refreshing to see.
This is a serious hardcore shop. They do everything. Diagnosis and very professional, knowledgeable repair. Machine work , and assembly. These shops are disappearing. I love the videos. 😊
I've been a Mechanical Engineer for 26 years. I absolutely love seeing the machining operations on these blocks. As one who knows how much precision is required, it is very impressive when it is done right.
I think everyone who’s engine failed because of a cylinder deactivation system destroyed it, should join together and class action suit the automakers, with a requirement for a full recall and deletion of this wholly unnecessary system that only causes premature, catastrophic failure of the engine.

Hello Dave: I love your channel & extremely impressed with your operation sir. In 2004 I retired from the auto repair industry as I had 2 independent repair shops. I would have combined them both as what you have done so brilently but the costs of real estate here in N.J. is ridiculous + the EPA fees ,& taxes. You have a terrific team of guys that you can trust + the way you run your business is admirable. All together I've been working on cars for 63 years & still do from time to time but I'm tired. After working all these years of 80 to 100 hour work weeks takes a toll on the body. GREAT JOB SIR & GOD BLESS. TMP from N.J.
Thank you Dave for your kind words. I wish I had started my business earlier in life so I could have built an amazing business and life as you sir. God Bless & my best to your family. TMP from N.J.
Make sure to use the Isky bushing type lifters and a Melling HV or Hellcat oil pump! This also happens on the non-MDS engines due to piss poor oil volume! I’m on my 4th set. Last time lost the cam and spun a cam bearing. Took the opportunity to go to a 426 with the Isky lifters and a Melling HV pump! Now has 47psi at idle at operating temp compared to the stock mopars 23 psi!

I did IT for a chrysler dealership and I was in the shop talking with the A-techs all of the time because they're ALWAYS tearing apart HEMIs. Despite popular belief of Displacement-on-Demand destroying HEMI lifters & cams due to it being a culprit for GM V8s, MDS isn't the issue here. MDS lifters aren't even the lifters that typically fail on the HEMI. The problem comes from a major design flaw from Chrysler where oil flowing from the cylinder heads back down through the block does NOT lubricate the camshaft at low-RPM. GM's AFM/DFM system takes 80,000-100,000 miles to do this kind of damage, yet you're showing us brand new lifters & a cam that failed and blaming it on cylinder deactivation. This kind of damage is probably from the owner constantly leaving his car idling for a long time whenever he parks it. No amount of good maintenance nor a DoD delete will stop a HEMI from blowing itself up if that's how the owner likes to treat his car.
@@petefroehling8704they aren't failing. And these hemi engines are sometimes going all the way to half a million miles. They have a better track record than any other V8 for the most part. They are also the most efficient V8 in all of history. People don't change the oil enough. They go too long. Low quality oil should realistically not stay in the engine past 2000 miles.. it's not rocket science. Oil changes should be done more often than the oil companies are not making a very good product to be honest. These engines are phenomenal.
Lack of oil changes is a big cause of AFM lifter failures. I work with a lot of guys that own 2014+ GM half tons with AFM. None of them have disabled it yet a few of them have over 200k miles. The biggest thing that they have in common is that they're old and they change their oil a lot. Like every 3000 or 4000 miles. They don't care what the 0w20 label claims, they change their oil very often. Makes sense. Especially with direction injection and the diesel-like soot it generates. Abrasive soot flow right through the oil filter. They also are not the type that remote starts their truck over and over every morning just to drive a few miles to work.
@@petefroehling8704 You beat me to it. These defective cop Hemi engines cannot sit at idle because the oil channels are not over the cams. Hence no lubrication.
Wow , From Junk to Running in one Video ! Very cool. Wow , The Machines You have there are a Whole lot different than the machine shop i Worked in n the 70's. That Block Boring Machine is insane !!! Boring & Cutting the deck in the Same machine & Spins the block for you too ! Absolutely nuts !!! We were all Manual back in the 70's. Had to jig it up , check everything. Then move it to the Mill if u wanted to Deck the block & Re Jig every thing up again. secure it down. check everything. i Guess it has been 49 years since ive been in that shop. Wow , Time Flys !!!
I hate multiple displacement engines but that is NOT the problem. This Hemi engine was designed defective from the factory .Oil reciprocating from the cylinder heads back down through the block does NOT lubricate the camshaft at low-RPM because the channels are not over the cams. Fix it as many times as you want but it will DO IT AGAIN !!!
Only way to keep them together is high quality synthetic oil, adding additional ZDDP to the oil, 5k oil change intervals and little idle time. Crank her up, give it 30 seconds, and drive gentle toll operating temp and enjoy. If you’re going to idle more than 3 minutes shut it down. You’ll get 300k plus easy
They fixed the lack of oil pressure at idle on the Hellcats with a much larger volume oil pump. Keeps the pressure up at idle so the can and lifters get oil. Melting now has a high volume pump to fix this on the non-Hellcats.
Not deactivation causes lifter failure. Happens on non deactivation lifters. Needle bearings in lifter roller too small and weak. 2018 onwards Hemi v8 fitted with heavy duty lifters with fatter bigger roller needle bearings. Same lifters used in Hellcat.
Correct but also wrong. Non MDS HEMIS have always had the same lifters used in the hellcat. From 2015 onward. There is no such thing as “hellcat lifters” non mds lifters in the 2500 trucks and 6 speed manual cars are the exact part number as the hellcats.
I am a poor guy from Ghana west Africa to be precise. One of my biggest dream is to be the best in engine rebuilding. I have a small shop with little or no set up at all. Even though am 41yrs old, am not giving up anytime soon. I came across this your channel like 3months ago and i enjoyed watching it. Looking at the kind of investment you made on the kind of set-up in your, i kept asking myself. Will i ever to set my shop up even with a quarter of your shop. Constantly watching you and your boys give me hope, that one day i will also get to see my dream come through. Am not giving up and my prayer is that i should live long to see it materialise. Keep up giving us such videos to keep our hopes alive. Peace
I really enjoy watching this channel. It reminds me when I was younger and my dad shop helping him build motors for customer cars and doing service and diagnosing problems.
An extended length video showing each step of the rebuild, what all the machines do, etc. would have me glued to my phone regardless of how long it lasts. Or maybe a series? Realize that’s a huge ask and y’all are busy as hell but there isn’t enough internal engine work content on YT, especially at this caliber. Getting to a point where I’m hooked, waiting for the next video you release. Keep up the outstanding work!!
I have done a dozen of the 5.7 and 6.4 or more for lifter failure. Its mostly on cylinder 3, and i found that odd. Its NEVER been an MDS lifter on any i have done. So thats not the problem. The MDS cylinders are 1,4,6,7. Now the Chevrolet is ALWAYS an AFM lifter. The pinlocks fail and the lifter stays collapsed, then the pushrod pops out and the lifter gets hammered until it spins and eats the camshaft. I have done over a dozen of these engines as well. The deactivated cylinders is also 1,4,6,7. Thats the 2 inside cylinders on one side and the 2 outside on the other side for balance.
Looks like someone did a crap repair on that one. The higher the mileage and the more worn it looks the less likely I will do the repair and sell an engine, or just refuse.
If all mechanics were honest it'd be easy to always say, "Yeah rebuild the engine". In the real world though, some guys will sell you a new engine for no reason at all. Good to see such passion for doing it right though.
Amazing, the gentleman Dave from my state, represent my state and all other states as assertive and direct towards the customer, who delights in in honesty and talent, which I delight in, two thumbs up
I remember when my srt grand Cherokee ate a lifter, the dealer did a cam and lifter instal and I specifically said I want a NEW motor, long story short, the gave it back to me and in 500 mile it had a lifter noise, well I proceeded to drive it so hard that the damage was beyond repair and I got a new motor out of it and the dealer paid for it. I have to say, they could have saved themselves 9k because my new 6.4 motor is 10k they spent 8+ on a top end rebuild.
It's known that the 3rd gen hemi engines have oil starvation when ppl idle their engines for long periods of time. Fleet vehicles are more known to happen the fix is replace the oil pump with a hellcat oil pump for more volume. Mds is not the problem they are just more susceptible to fail first. Lots of vids on this.
If you switch to a high volume oil pump you have to also install a larger oil pan, otherwise you'll empty it at higher RPM's. Many, many "car guys" have found this out the hard way.
@@COBRO98 This is an OLD known issue on Hemi's from the 392's in the 50's. Especially the 60's Hemi's run the pan dry and KA-BOOM goes the engine. These newer engine are NO Different, NONE! Fact Many other engines went to the grave for this specific reason Stock pan, prolongs High RPM's starvation issues exploded engines, Lotsa Chevies, Pontiacs, Olds, Buicks. My 428 SCJ would FILL the rocker lids in maybe 5 second and the oil press gauge "flickering right at the end of a run. NO engine can drain back fast enough!!! NO ONE ! To alleviate this dilemma is Only resolved by 3 qt capacity addition on oil pan, Plus oil feed restricters on RA shaft feed or and oil restrictive pushrods. .I seen this way back in the 70's and heard this exclusively in the shop I was in. Guys buy the car craft" magazine "hop up kits" and two weeks later with 50 more HP out at the cruises racing, one explosion after another coast to coast. The Gen 3 engines Dodge, are WELL Known for the very stupid design of Oil splash is WOEFULL insufficient, the cams lobes need oil, and consequently, ALL the cam grinding shops portray this engineer design FLAW. Go look at the 110 blocks POOR design degree angle, actually prevents cam lobes from getting proper oiling, LOL, It's pure unbelievable stupidity of a design. I've had to address this Oiling FLAW design Issue countless times yet the donkeys thing Dodge are OK", Absolutely are NOT! The GEN-3 are the WORST engine for this problem. I'm surprised this guy didn't speak to this Well known FLAW issue. I'll NEVER own one even if it was given to me wouldn't do anything but SELL IT Immediately.
I wanted to commend Dave's son the engine builder. You can tell alot about a craftsman by looking at his work space and tool box. He learned well Dave, clean and organized!!! Good job.
If I ever need or want an engine done, I would love to have you guys do it. Dave, your son has learned to be one of the best engine builders and he should be proud of himself, his knowledge and skills.Great work as always.
2008 and down Hemi was good for dropping the valve seats and blowing holes in pistons. 2009+ are good for locking up the roller lifters and wiping the cams.
An absolute pleasure watching true "craftsmen" working there magic vs just a "tradey" who has no passion for doing the job right. Great episode again Dave & Co. Very informative & educational. Keep up the good work 👍
From watching these videos, I’ve learn tons. Not a mechanic , I do maintenance on my stuff. Gives me more understanding. Especially on oil , lubricant stuff
What a great video, I prefer these where there's a start to finish and you guys do such a great job, don't be shy though to tell us how much that rebuild cost.

My 11 Grand Cherokee has the hemi, I do my oil changes early, every 3-4,000miles to avoid this. So far so good, so have a stud missing on my manifold lol.
Was going to mention, once I did a 300c 5.7 hemi engine job and the new reman engine was shipped with special intake gaskets that were implented with screens to prevent shrapnel from going back into the engine because they drop valves or have lifter failure. Its important to really keep intake manifolds clean or atleast check it out before you throw it back together! I shook mine about and heard pieces and went and got a new factory unit as a replacement, screw doing the job over again because you reused a vital piece!
Yes, start to finish episode, loved it! thx! would be cool with some performance numbers, improvements or not, how long it's estimated to last etc and why :)
I just love this video, and all the others like it. Just listening to all your knowledge and experience you so willingly share with us all is a real eye opener at times. I hope your competitors watch too, some of them obviously really need too. Many thanks David in the UK.
Cylinder delete was a bad idea from caddilac's first try in the 70s and 80s. Chrysler has enough problems with cams and lifters........ without variable displacement gear!!
In hemi engines, the only time the MDS lifters get oil is when MDS is activated. All other times, they are starved for oil, which is what casues them to fail.
You are completely right about those multi displacement engines MDS they’re called on the hemi’s . The thing is is if your engine eats a lifter, you have to tear the engine apart to clean it. You can’t just leave all the debris in there like that it’s gonna eat another lifter. I think the other thing is also is there’s low oil pressure when the engine is running at idle it’s not sufficient enough to get all that oil up to the head when the multi displacement MDS drops you down to four cylinders those lifters are still smacking. A few guys have gone and put the hellephant engine oil pump in the 5.7 and change out that mds lifter and system . But not all engines are doing this just the ones that sit ant low rpm lots it starve of oil because of the oil pumps that’s what I think
The weird thing is that the 5.7 hemis from 2005 thru 2010 had MDS and lifter failure was not an issue. When they added variable cam timing in 2011 the lifter issue rose its ugly head. They also had about 50 more hp so that proabably meant higher lift cams that may have started the lifter failure due to stronger valve springs. The early hemis did have a potential problem with valve seats dropping which was fixed in the later models. I bought a new 2005 Dodge Magnum with the 5.7 hemi and I loved that car. It was roomy comfortable and fun to drive due to the hp/torque of that engine. I sold it last year 2023 with 120k miles on it.
The roller bearings in the early lifters are tiny. The 2009+ are much bigger with a thinner piece of metal that rides on the cam. Did this cause the issue in the 2009+? I have used used lifters from early engines in cam swaps😆
Blame the EPA, dodge, our government in general for saving us all by causing the premature failure of many products which gets paid them thrown in a landfill and forcing the manufacture of another, usually three times per life cycle.....
These a e great videos, clearly very professional and experienced shop and striving for excellence but please NO more music, just the shop sounds are good enough.
Dave, I own a 02 Ram and about to trip 200K on it. I always use 15-50 synthetic oil. The only problems I have experienced is the water pump, starter and alternator. I have not been nice to it and it still runs great. I appreciate your videos. Congrats on your Discovery deal. Looking forward to watching.
Thank you for the information! I love to know WHY these things happen, and what happens when you just fix the issue without looking at the bigger picture.
Dave, if I could afford it, I would definitely send my engine to you to delete the AMF from my LS3 Caprice. I am very fussy who touches my engine. You are the real deal. Love your work brother.

You know, I just randomly came across this channel as it popped up in my feed. The old algorithm just knows that I watch a lot of car stuff. I'm so glad that they did that for me because now I am a subscriber and make comments here and there and I watch every video. Just wanted to say I think it's a great channel and I'm glad I found it.

I wish I was 40 years younger. As a retired qualified artisan in motor vehicle technology, I would have taken a wild card and asked you for a job. I still enjoy doing repairs but only smaller stuff. I think it is the most enjoyable trade ever!!
Wow this thing took out the whole motor, that’s crazy I know once a rocker arm blows those little needler bearings are bad. Usually I see just a lifter gets stuck and eats a cam journal. You machining everything and making sure it’s right from the start, wow speaks volumes great video
Hey Dave, I've got the same motor in the same type of car. I just wanted to give my two cents on the big reason these hemis fail. The 5.7L specifically was built for lower hp when it first came out and oiled well for that application, but it was upgraded all except the oil pump into the chargers, challengers, 300s, durangos, and newer rams. The cylinder deactivation isn't the big killer of these engines, but rather the piss poor stock oil pump that gets around 9 to 14 psi of oil pressure at idle with warm oil. Idling at operating temps can damage these engines, thus, personally, I would offer a recommendation for a Mellings Oil pump, which has had extensive research on it to increase oil pressure by some amazing creators on this site. Just my two cents, great video and I love learning more about all types of engines, especially the one I have
Awesome shop Dave! Wish I lived in your area, would love to work there man, you have no idea! Great work, great job, you guys are precise to every single little detail. Love that man. You guys have the respect of millions!! Need more Dave’s in this world. And his team!! 🎯
As a wee lad back in the day, when I first started buying tools and twirling spanners on my first car. My father said to me 'cry once'. Don't half do a half-arsed repair, because you'll only cry again when the repair fails and you have to do it again, properly. This is a prime example. I'm 60 now, he's 85, and all he does now is accuse me of being too pedantic 😅. The Hemi sounds awesome. I owned Chryslers for 20 yrs until Chrysler Australia folded. Dodge and Jeep are back here now, I wish the Chargers and the Challengers were. Great vid. You guys make it look all too easy. 👍🇦🇺

Correct but also wrong. Non MDS HEMIS have always had the same lifters used in the hellcat. From 2015 onward. There is no such thing as “hellcat lifters” non mds lifters in the 2500 trucks and 6 speed manual cars are the exact part number as the hellcats.
I am a poor guy from Ghana west Africa to be precise. One of my biggest dream is to be the best in engine rebuilding. I have a small shop with little or no set up at all. Even though am 41yrs old, am not giving up anytime soon. I came across this your channel like 3months ago and i enjoyed watching it. Looking at the kind of investment you made on the kind of set-up in your, i kept asking myself. Will i ever to set my shop up even with a quarter of your shop. Constantly watching you and your boys give me hope, that one day i will also get to see my dream come through. Am not giving up and my prayer is that i should live long to see it materialise. Keep up giving us such videos to keep our hopes alive. Peace
Love visiting Accra ! Oxford st ❤😂
This is cool to hear. I wish you luck in your ventures.
Your tremendous courage is evident. We are cheering you on from Utah!
That engine block looks great after it got cleaned. Awesome job guys
I really enjoy watching this channel. It reminds me when I was younger and my dad shop helping him build motors for customer cars and doing service and diagnosing problems.
Very cool!
An extended length video showing each step of the rebuild, what all the machines do, etc. would have me glued to my phone regardless of how long it lasts. Or maybe a series? Realize that’s a huge ask and y’all are busy as hell but there isn’t enough internal engine work content on YT, especially at this caliber. Getting to a point where I’m hooked, waiting for the next video you release. Keep up the outstanding work!!
Appreciate the feedback!
I have done a dozen of the 5.7 and 6.4 or more for lifter failure. Its mostly on cylinder 3, and i found that odd. Its NEVER been an MDS lifter on any i have done. So thats not the problem. The MDS cylinders are 1,4,6,7. Now the Chevrolet is ALWAYS an AFM lifter. The pinlocks fail and the lifter stays collapsed, then the pushrod pops out and the lifter gets hammered until it spins and eats the camshaft. I have done over a dozen of these engines as well. The deactivated cylinders is also 1,4,6,7. Thats the 2 inside cylinders on one side and the 2 outside on the other side for balance.
It’s low to no oil pressure at idle to the top end, from what I understand.
Looks like someone did a crap repair on that one. The higher the mileage and the more worn it looks the less likely I will do the repair and sell an engine, or just refuse.
Enjoyed this condensed start to finish. Well done
Dave, wonderful to see you saved another sublime sister car of mine, great job Sir
Sublime is the best Charger color!!
*Dave's Auto Center* Bravo well done, thank-0you sir for taking the time to bring us along. GOD Bless.
If all mechanics were honest it'd be easy to always say, "Yeah rebuild the engine".
In the real world though, some guys will sell you a new engine for no reason at all.
Good to see such passion for doing it right though.
THANK YOU!
For showing a diagnosis to complete rebuild.
Fantastic job, thanks for taking us through the whole process.
Its so good that you are honest and upfront with your clients, it says so much trouble later on down the road
Watching the engine get cleaned is so therapeutic
Amazing, the gentleman Dave from my state, represent my state and all other states as assertive and direct towards the customer, who delights in in honesty and talent, which I delight in, two thumbs up
Awesome channel Dave. Great shop. 🙂.
nice recovery, appreciate the break down! A car worth restoring for sure!
Given the quality of work you guys do, it blows my mind how you guys never have gloves on.
I remember when my srt grand Cherokee ate a lifter, the dealer did a cam and lifter instal and I specifically said I want a NEW motor, long story short, the gave it back to me and in 500 mile it had a lifter noise, well I proceeded to drive it so hard that the damage was beyond repair and I got a new motor out of it and the dealer paid for it. I have to say, they could have saved themselves 9k because my new 6.4 motor is 10k they spent 8+ on a top end rebuild.
It's known that the 3rd gen hemi engines have oil starvation when ppl idle their engines for long periods of time. Fleet vehicles are more known to happen the fix is replace the oil pump with a hellcat oil pump for more volume. Mds is not the problem they are just more susceptible to fail first. Lots of vids on this.
Very true
Exactly
If you switch to a high volume oil pump you have to also install a larger oil pan, otherwise you'll empty it at higher RPM's. Many, many "car guys" have found this out the hard way.
@@COBRO98wrong. Hellcat Oil pan is the exact same. No issues at all. These engines actually have very good drain back
@@COBRO98 This is an OLD known issue on Hemi's from the 392's in the 50's. Especially the 60's Hemi's run the pan dry and KA-BOOM goes the engine. These newer engine are NO Different, NONE!
Fact Many other engines went to the grave for this specific reason Stock pan, prolongs High RPM's starvation issues exploded engines, Lotsa Chevies, Pontiacs, Olds, Buicks.
My 428 SCJ would FILL the rocker lids in maybe 5 second and the oil press gauge "flickering right at the end of a run.
NO engine can drain back fast enough!!!
NO ONE !
To alleviate this dilemma is Only resolved by 3 qt capacity addition on oil pan, Plus oil feed restricters on RA shaft feed or and oil restrictive pushrods.
.I seen this way back in the 70's and heard this exclusively in the shop I was in.
Guys buy the car craft" magazine "hop up kits" and two weeks later with 50 more HP out at the cruises racing, one explosion after another coast to coast.
The Gen 3 engines Dodge, are WELL Known for the very stupid design of Oil splash is WOEFULL insufficient, the cams lobes need oil, and consequently, ALL the cam grinding shops portray this engineer design FLAW.
Go look at the 110 blocks POOR design degree angle, actually prevents cam lobes from getting proper oiling, LOL, It's pure unbelievable stupidity of a design.
I've had to address this Oiling FLAW design Issue countless times yet the donkeys thing Dodge are OK", Absolutely are NOT! The GEN-3 are the WORST engine for this problem.
I'm surprised this guy didn't speak to this Well known FLAW issue.
I'll NEVER own one even if it was given to me wouldn't do anything but SELL IT Immediately.
ComeOnMan......A good and honest mechanic is worth his weight in gold.
I wanted to commend Dave's son the engine builder. You can tell alot about a craftsman by looking at his work space and tool box. He learned well Dave, clean and organized!!! Good job.
I like the pre-oil system, really nice !!
Yeah those systems are fine when they work. Just like DPF and SCR on diesels. When they break gets expensive. Great work Dave!
Engine looks so mint after the fix. Love to see it!
If I ever need or want an engine done, I would love to have you guys do it. Dave, your son has learned to be one of the best engine builders and he should be proud of himself, his knowledge and skills.Great work as always.
The cylinder deactivation is a joke, I don’t care what anyone says it’s not good to run dead cylinders.
Don't forget a melling high volume oil pump.
I was gonna the pan makes it a pain😭
Extremely impressed with your work.
So glad you were able to show us a project from start to finish. Thanks Dave and Team
2008 and down Hemi was good for dropping the valve seats and blowing holes in pistons. 2009+ are good for locking up the roller lifters and wiping the cams.
This is a perfect description for any lay person considering one of these used.
An absolute pleasure watching true "craftsmen" working there magic vs just a "tradey" who has no passion for doing the job right. Great episode again Dave & Co. Very informative & educational. Keep up the good work 👍
Thanks 👍
From watching these videos, I’ve learn tons. Not a mechanic , I do maintenance on my stuff. Gives me more understanding. Especially on oil , lubricant stuff
Damn, you guys are good. Just watching that CNC boring machine was amazing.
Wild guess, lifter failure? On a Hemi, who would have guessed. Now I’ll watch the video.
What a great video, I prefer these where there's a start to finish and you guys do such a great job, don't be shy though to tell us how much that rebuild cost.
Thanks for the feedback We usually don't quote prices on a video because the videos will be out for years. But you can see our products and prices on our website at monsterengines.com 👍. Appreciate you watching our channel. Have a wonderful day.
Man that shop of yours is state of the art. All the machines to handle any task.
9:55 Wow 🤩 so satisfying to watch the machinery in action and see the precision and detail in every engine…Saludos!!!!👋😃👋
Great wholesome all the way thru the process video, outstanding I'd love to work for this guy.
Much appreciated!
@@DavesAutoCenterCenterville not only the content, but your values, I work on houses for a living. I have my own business and its not a given to find people with integrity quite like you do. To people like us its a way of life. But its not a a common thing. And when I see people like Dave i really appreciate it because its an everyday practice an every decison practice. Each and every decison even if it goes unnoticed. Thanks for being wholesome to the core.
My 11 Grand Cherokee has the hemi, I do my oil changes early, every 3-4,000miles to avoid this. So far so good, so have a stud missing on my manifold lol.
That won't avoid anything. You need to get the AFM system deleted to avoid this
@@Sixpointtwoliter the rear diff just went, clutches broke in it… selling it now lol
@@Sixpointtwoliteryou’re wrong. Non MDS HEMIs have also got this problem.
@@pushhrodd01 that's great. The specific problem in the video was due to an AFM lifter
@@Sixpointtwoliter mopar does not have AFM it’s MDS. And it’s been proven that’s not the cause of it
Honest mechanic can’t do much better great job. Regardless of cost you have to charge what you are worth, you do a good job you get rewarded
Was going to mention, once I did a 300c 5.7 hemi engine job and the new reman engine was shipped with special intake gaskets that were implented with screens to prevent shrapnel from going back into the engine because they drop valves or have lifter failure. Its important to really keep intake manifolds clean or atleast check it out before you throw it back together! I shook mine about and heard pieces and went and got a new factory unit as a replacement, screw doing the job over again because you reused a vital piece!
This is a great American honest auto mechanic shop! Wish all shop owners took pride in their work
Idle time is a big killer on these I know in the fleets that idle all day this is a huge problem
Yes, start to finish episode, loved it! thx! would be cool with some performance numbers, improvements or not, how long it's estimated to last etc and why :)
Bot.
@@highnoon5189 troll
Your shop is top-tier second to none great job on the whole engine repair. It’s nice and clean.
Love your videos. The professionalism of your guys shop is amazing to see.
Thank you very much!
I think it's a oiling issue at lower RPMs?
Yes, it definitely is. At idle these engines, for 2 decades, can’t produce enough oil pressure to lubricate the top end.
Nice work
I just love this video, and all the others like it. Just listening to all your knowledge and experience you so willingly share with us all is a real eye opener at times. I hope your competitors watch too, some of them obviously really need too.
Many thanks
David in the UK.
Always a joy watching your videos Dave 👍🏼
Cylinder delete was a bad idea from caddilac's first try in the 70s and 80s. Chrysler has enough problems with cams and lifters........ without variable displacement gear!!
In hemi engines, the only time the MDS lifters get oil is when MDS is activated. All other times, they are starved for oil, which is what casues them to fail.
Thats not true
Love this channel well informative and love how they do all in-house work themselves. As a mechanic myself Dave is as solid is they get!
You are completely right about those multi displacement engines MDS they’re called on the hemi’s . The thing is is if your engine eats a lifter, you have to tear the engine apart to clean it. You can’t just leave all the debris in there like that it’s gonna eat another lifter. I think the other thing is also is there’s low oil pressure when the engine is running at idle it’s not sufficient enough to get all that oil up to the head when the multi displacement MDS drops you down to four cylinders those lifters are still smacking. A few guys have gone and put the hellephant engine oil pump in the 5.7 and change out that mds lifter and system . But not all engines are doing this just the ones that sit ant low rpm lots it starve of oil because of the oil pumps that’s what I think
The weird thing is that the 5.7 hemis from 2005 thru 2010 had MDS and lifter failure was not an issue. When they added variable cam timing in 2011 the lifter issue rose its ugly head. They also had about 50 more hp so that proabably meant higher lift cams that may have started the lifter failure due to stronger valve springs. The early hemis did have a potential problem with valve seats dropping which was fixed in the later models. I bought a new 2005 Dodge Magnum with the 5.7 hemi and I loved that car. It was roomy comfortable and fun to drive due to the hp/torque of that engine. I sold it last year 2023 with 120k miles on it.
The roller bearings in the early lifters are tiny. The 2009+ are much bigger with a thinner piece of metal that rides on the cam. Did this cause the issue in the 2009+? I have used used lifters from early engines in cam swaps😆
Blame the EPA for "saving" the earth
Yes because they had direct hand in creating the motor ...good job bud
Clean air. Who needs that
Blame the EPA, dodge, our government in general for saving us all by causing the premature failure of many products which gets paid them thrown in a landfill and forcing the manufacture of another, usually three times per life cycle.....
These a e great videos, clearly very professional and experienced shop and striving for excellence but please NO more music, just the shop sounds are good enough.
Dave, I own a 02 Ram and about to trip 200K on it. I always use 15-50 synthetic oil. The only problems I have experienced is the water pump, starter and alternator. I have not been nice to it and it still runs great. I appreciate your videos. Congrats on your Discovery deal. Looking forward to watching.
Thank you for the information! I love to know WHY these things happen, and what happens when you just fix the issue without looking at the bigger picture.
Greetings from Canada 🇨🇦. Always a great pleasure watching you and your team work your magic. Thanks again, Dave 😊
Our pleasure!
Love to watch you guys work! Pros!!
These vids must watch all the way no skipping great job and couldn't agree more to document document document!!
Dave, if I could afford it, I would definitely send my engine to you to delete the AMF from my LS3 Caprice. I am very fussy who touches my engine. You are the real deal. Love your work brother.
Love these videos! The crew at our shop loves the work you guys do and the awesome coverage. Top shop for sure!!!!
Awesome! Thank you!
I always like to see value added to older well kept vehicles. Thanks Dave.
I'm pretty sure that job had to cost more than the whole vehicle is actually worth.
@@daveclark8337 you mean like the value of the ever depreciating federal reserve bills in your bank account? I prefer hard assets. If the customer wants to spend his or her money on a known commodity than give them the choice.
You know, I just randomly came across this channel as it popped up in my feed. The old algorithm just knows that I watch a lot of car stuff. I'm so glad that they did that for me because now I am a subscriber and make comments here and there and I watch every video. Just wanted to say I think it's a great channel and I'm glad I found it. (Even though it was an accident) 😂😎 Hey, just because I'm lazy and don't wanna go look, are you guys doing merch yet? Thanks!! 🤣👍🏼👍🏼😎
Best content on UA-cam these days. Always entertaining 🙏
Best automotive channel on youtube
i love the work you guys do. Im currently in trade school to become a technician and this channel inspires me when things get tough! love you guys!!!!
I wish I was 40 years younger. As a retired qualified artisan in motor vehicle technology, I would have taken a wild card and asked you for a job. I still enjoy doing repairs but only smaller stuff. I think it is the most enjoyable trade ever!!
Wow this thing took out the whole motor, that’s crazy I know once a rocker arm blows those little needler bearings are bad. Usually I see just a lifter gets stuck and eats a cam journal. You machining everything and making sure it’s right from the start, wow speaks volumes great video
Hey Dave, I've got the same motor in the same type of car. I just wanted to give my two cents on the big reason these hemis fail. The 5.7L specifically was built for lower hp when it first came out and oiled well for that application, but it was upgraded all except the oil pump into the chargers, challengers, 300s, durangos, and newer rams. The cylinder deactivation isn't the big killer of these engines, but rather the piss poor stock oil pump that gets around 9 to 14 psi of oil pressure at idle with warm oil. Idling at operating temps can damage these engines, thus, personally, I would offer a recommendation for a Mellings Oil pump, which has had extensive research on it to increase oil pressure by some amazing creators on this site. Just my two cents, great video and I love learning more about all types of engines, especially the one I have
Awesome shop Dave! Wish I lived in your area, would love to work there man, you have no idea! Great work, great job, you guys are precise to every single little detail. Love that man. You guys have the respect of millions!! Need more Dave’s in this world. And his team!! 🎯
Thanks 👍
Dave you are a freaking neurosurgeon with an engine. Great vid
😂👍
A great looking engine machine shop and like the fact that you have to completely fix the problem or suffer the consequence.
Dave, love your work. You know how different components work great master mechanic with a well run shop. Have a blessed day jimmy Dixon
Fantastic episode. Well done!
Recently found gour. Channel sir.i am Jamaican and i love how knowledgeable you are sir..i wish for you and your team good health and Long life.🙌
As a wee lad back in the day, when I first started buying tools and twirling spanners on my first car. My father said to me 'cry once'. Don't half do a half-arsed repair, because you'll only cry again when the repair fails and you have to do it again, properly. This is a prime example. I'm 60 now, he's 85, and all he does now is accuse me of being too pedantic 😅. The Hemi sounds awesome. I owned Chryslers for 20 yrs until Chrysler Australia folded. Dodge and Jeep are back here now, I wish the Chargers and the Challengers were. Great vid. You guys make it look all too easy. 👍🇦🇺
