- What starts off as preventative turns into a necessity when we find out this engine was closer to failure than we thought.

Why did I just get an SRT and start watching engine failure videos!
sasme lol
Same 😂😂
I have a love/hate relationship with these engines. I am not a mechanic, but have done all my auto work since a teenager. I rebuilt the top end on my dads 2015 5.7 and my 2014 ram with a 5.7 a few weeks apart. Both had #5 intake lifter failures around 100k miles. The engine was easy to work on and simple enough that I wasn't too intimidated to do it myself. We are both a year in with no issues. We have not had any other major or even minor issues with our trucks. I hate that the lifters fail, but it was cheap enough to rebuild and hopefully get another 100k miles out of our trucks. Other than the cam and lifters our engines looked practically new. Really impressive. Side note: MDS is NOT the issue. OCI, type of oil, and lifter quality was the issue.
What oil do you use ? I'm trying to take care of my 6.4

Thanks for answering 21 ram 5.7 and now 21 SRT Jeep both low milage but new to me under 30k. Just did truck with 5/20 so I think 5/30 seems to be a better choice
Nice work guys. It's pretty crazy that that's the engine that's in the 392 Jeep Wrangler.
Edit: I'm a little shocked you went that deep and didn't replace the timing chain.
I have yet to drive the 392 wrangler but i can imagine it goes pretty good after driving this.
wtf they didnt replace the timing chain? wow
I pulled an 09 5.7 from a charger that caught fire. I dont have much $$$ to throw around, so I had to repair the lifters I had. I used the rollers from a GM 3.8L V6 , pressed out the junk hemi pins and installed the GM parts, worked perfectly. Took off the cam phaser, machined the sprocket flat and flipped it over so it would bolt on backwards, welded a Ford 4.2L v6 oil pump drive gear to the sprocket. Using the gear and shaft from the ford cam sync, I welded them to a modified GM distributor. Down next to the timing chain guide I made a small bearing for the oil pump shaft to rest in. The hole for the cam sensor had to be widened to get the correct angle of the cam gear , it ain't pretty but it works. The throttle body on the intake had to go, and in place of it an adapter. An adapter for a TBI system from a 94 GM pickup truck. Does it work, yes. Is it powerful as it could be? No. But it still kicks @$$ with the modified 4L60E. Thats a story in itself. Casted the bell housing and all to adapt the hemi to the chevy trans. Lots of beer cans.
Thats impressive, well done!
I’ve pulled my 5.7 down a couple of times and if I do it again, the ‘Hellcat’ lifters and oil pump will be mandatory.
We thought about doing the oil pump but decided against it since it ran fine we were just doing it preventively. Wouldn't have been a bad idea though 👍
@@desertwrench The only reason I would go the ‘Hellcat’ pump is that it has a higher oil pressure at idle. My replacement lifters ( 2nd set) has one that occasionally taps at idle, so with a few more rpms, it goes away. I regret trying to do the job on the cheap. Next time, nothing but Mopar parts, especially anything to do with the ‘Hemi tick’.
We went with the Texas speed kit and they use OEM lifters
The updated Mopar lifters are the way to go. It's usually not the MDS lifters that fail. You cam was not bad, nor did you have a locked up roller. The cam and lifter that came out of my 5.7 was chewed up. You did have what looks like a little metal fatigue on the cam nose.
Yeah there was a little chunk missing out of the top of the lobe, we changed the oil and flushed everything prior to starting it up.
I have been an automotive technicians for 19 years. I have owned my own shop for the past 11. I have done, hundred (if not thousands) of spark plugs on Hemi's. I have actually owned a 2012 RAM 1500 w/ 5.7L & a 2016 2500 w/ 6.4L & have never had a spark plug break inside the head, not have I ever seen it on a Hemi. Ford 5.4's it was very common, actually expected, but not on a hemi. Someone definitely over-tightened those spark plugs
It was definitely surprising, you expect it on 5.4's
A Melling 10452HV oil pump is the highest volume pump, this and high grade 5w-30 oil changed every 3,000 miles is the best way to go. I have just bought a Grand Cherokee 5.7, only 13,400 miles on it. I have ordered the pump from Summit. Lots of idling is what creates Hemi tick. The Melling 10452HV gives 20% extra oil volume, essential at idle.
Nice work you guys, can't wait to hear it rip 💪
Finally got it back from the body shop so hopefully soon!
I'm reluctant to call those combustion chambers hemi! (hemisphereical) compared to old 426 that is, It seems the new hemi's are in name only. Now I know why Chrysler bought the trademark name hemi! Even Harley-Davidsons 1984 & earlier were all real genuine hemis (little known fact) anyway there still pretty Kool and can really haul ass!
Hence the all caps (HEMI) ...Branding versus (shape)
The plastic plugs open up the oil passage internally not block it off. That engines been apart before, the factory didn't put that copper spray on the head gaskets. I've been working on these hemis for 20 years now and almost every single failed lifter I've replaced was 09-14, not 100% in that year range but definitely most of them. Non mds engines have high lifter failure rate also and most lifters that have bad rollers are non mds lifters. Also I can tell you that there are plenty of failures in low miles engines with great oil change history. Good maintenence does tend to save the rocker and push rod mating surface but the lifter is doomed from new. In 2009 dodge was on the brink of another bankruptcy and cheaped out on lifters plain and simple. It is not the oil system that causes it, they are the same as earlier ones that were just fine. I've seen several guys over the year stick a push rod in the oil hole and wonder where it went, they actually get stuck in the block and don't make it to the oil pan.
Those are absolutely NOT oem lifters! That little oil hole in the cut out is not on any factory lifter. Also not the right box or lifter tray, they are the cheap chinese ones on fleabay. Texas speed got in some trouble about that, I would get real Mopar lifters.
Spot on. Current MOPAR lifters are beefier in final evolution design to outlast time itself.
I've been Mopar to the core for 50 years. Walter P. would roll in his grave to see the influence Daimler left on his company. I now drive Toyota.
Man, what a lesson, I really enjoyed your video, and it surely borders the unbelievable how this thing is designed with so many imbeded gremlin gadgets that it just must fail sooner or later
I wonder why do so many people enslave themselves at work to then buy hunk-a -junks like this, the reliable simplicity of yesteryear is well gone, new designs are being implemented here and i can''t help thinking that this monstrosity, as the like ones from almost all the other brands, mostly the big named ones, are created due to only ONE thing, the Climate Histeria, why else would a competent car manufacturer ultra complicate things, and build to fail and then repeat it, over and over, if he was not made to...
and of course people are to blame too, because they lay down their money on thin gold plated big hp fake gems like this, built to fail, even when most of the time they are still being driven slow, at the speed limits. Regulations are failing big time,for too long now...
Good luck with the engine now, that was a lot of work, hope you won't have to pull it again like many have.
Glad you liked it! Yeah, with stricter regulations all the overly complicated systems do create more failure points for sure but at this point its best to enjoy the ride and do what we can, while we can 👍
Fragile, garbage engines. They all fail by 80-90k
It's mostly a hardening issue or a failure of the lifter roller bearings that causes the dreaded tick. Newer motors should have the updated lifters and better hardening on the cam.
yeah manufacturing during bankruptcy... a few micros of bad machine work and your lifter is doomed... these are machined down to a single micron.
I mean ya but are there newer 2017+ motors still experiencing this commonly?
And on that note idk since my truck isn’t tuned yet a 2018, should I use mds or try to leave it off?
It's called zinc. Put about 3oz. Of zinc assembly lube in when you change the oil. I have 160k on my 06 5.7 and it's so quiet you can hear the injectors.
there are lots of choices.. i think Assembly Lube is the best ..
If I owned that motor it would be Redline 5-30 oil only with an OCI of 3000 miles. Only oil on the market that gets rid of Hemi Tick. Its all I use on my cars.
Is there a place that sells it for a good price?
@@mtn-endeavors67 Not really Jegs is your best bet.Worth every penny.
Here I am with my 392 charger at 92k miles having lifter failure 😢
For the mds solenoids do you have to leave the one with the screen plugged in? And also what did you guys put on the oil pan as the gasket? Nice work 🔥
We removed all of the solenoids and then just tuned it for the CEL. We used ultra black rtv for the pan gasket. Still holding strong!
Why didn't you drop the oil pan to ensure a quality seal instead of using the gasket maker?
Because we dropped the engine out the bottom of the vehicle in a previous video so at this point it's still mounted to the subframe, with transmission and everything still bolted up. Since it's just flowing down into the pan at this point it was a risk we were willing to take.
Hi there …. I already have a very faint tick.
my 2019 392 Challenger has only done 16,000 miles.
There is no guarantee because it is an import vehicle in Germany.
Also, I need 1 liter of oil for 1000 miles... is that normal for HEMI's?
For example, my Iroc Camaro doesn't need anything ... I never have to refill anything ...
my 392 didnt use any oil.
I've heard all the theories about why this happening, the last guy i talked to was an engine designe engineer he said the Valvetrain geometry in the hemi puts the rockers in abnormal loads subsequently causes a lifter roller failure and he praised GM BBC Valvetrain designe in contrast
wrong...
@@darthhemi1735 what's right?
@@Airman.. it was just crappy lifters during bankruptcy... 2009-2013... the geometry has been the same since 2005... and 2005-2008 hemis did not have this problem... so that eliminates geometry and oiling... and the geometry is STILL the same today..
@@darthhemi1735 I've seen newer models doing it at around 60-100k mi
@@Airman.. but very very rare
I hope you guys submerged those lifter in oil for a 1h at least before installing them😢😢
awesome video, you guys know your stuff? How many miles did this engine have on it when you received it for repair?
Thanks! It had 97k miles on it.
2019 onwards Hemi production have heavy duty lifters installed. Same heavy duty lifter in 6.4 same lifter used in Hellcat engine aside from MDS lifter. Issue with earlier lifters are pissy little needle roller bearing used in roller were too small, too weak and suffered from early life failure. Not MDS issue. Just fit latest factory lifter and problem solved.
the final lifters were in 2015... they have been the same since then. They are all "hellcat" lifters.
@@darthhemi1735 sure 2015 used similar lifter design from original supplier, but also not so reliable. Change of supplier thereafter. Block also changed to BGE,same as Hellcat block.
The new hemi doesn't have hemisphrical heads like the old hemi, they're just using the name....
Great video!! Really enjoyed it
You all say what you want but the HEMI is and always will be king but not the new model its sad they bring it back only. To F.?.?.?. It up.
Did you use 5w40
Putting everything back together we used Lucas Assembly Lube and for the oil change it calls for 0w40.
Fix the 5.7's all the time. Delete them as well. Fix the 3.6 pentastar tick alot as well.
Were they still pretty common in the 2017+ models? I’m worried about mine being a 2018
@mtn-endeavors67 dodge always says they've updated the lifters in newer 5.7s. I work on 2012 chargers with 5.7s and never had that problem. I think it's hit or miss.
Hellcat oil pump.
We thought about that, for now we have good oil pressure (yes its reinstalled, video should be coming out May 13). If we end up having to do it in the future its just a lesson to do everything on the next one 😅
Well. If you maintain your vehicle, do good oil change intervals and don’t dog the engine and it still breaks it’s time to switch brands. Engine just has cheap internal parts.
This is what is called an accountant engine made cheap low cost will it fail they do
що вони розбирають ВОНО ВСЕ НОВЕЕ!!!!!!!!!
"Tearing it down" to the short block isn't really tearing it down at all. I wouldn't be too optimistic about this mill living a long and fruitful life.
I think they did ok. That engine was super clean inside and the pistons and combustion chambers looked great. Other than overtightening the driver's side spark plugs, it appeared to be fairly well taken care of.
Myself, I would have pulled the oil pan and checked some bearings, while the engine's out of the vehicle, cleaned the pan and used a new gasket to reseal it. But I wouldn't expect to find anything terrible, just for peace of mind.
Many hemi engines live a long healthy life after the cam is completely chewed on a cylinder. This one has very little wear in comparison.
pretty rusty old a$$ engine...
90 thousand miles? Good I have 50 more to go.. I'll trade my srt by then
Be more worried about the “ hemi” rods out the side of the block😂😂😂
😂 Hopefully it doesn't come to that!
@@desertwrench don't worry about the rods, that happens from hydro locking them, the early Durango in particular had a bad design that caused it. Unless you drive through deep water or otherwise flood the engine the rods are very good in a 6.4.
