2015 Ram 2500 6.4L Hemi Engine Teardown. THIS IS WHY Replacement/Rebuilding Is REQUIRED! (Hemi Tick) 

Removes 4 hose clamps. Proceeds to cut the hoses and leave them on the fittings 😂

I have been in the hospital all day with covid complications, and I honestly forgot its Saturday. When I saw the notification of a new engine teardown, it literally brightened my day. Thank you, Eric. Thank you.

Eric, you have single-handedly convinced me to reduce oil change intervals on all my cars. It’s just cheap insurance

I just bought a 2023 6.4 hemi vehicle. I've got 250 miles on it, and now I know how to protect it, thanks to Eric.

Is anybody old enough to remember when windage trays were exotic?

My wife, "why do you watch this stuff". Because I am a man. It is amazing what you can learn watching an engine be taken apart. agree?

Fans all over the world. Yes, yes you do. You have such a great sense of humor. Thanks!

I have replaced 100-120 of these HEMI engines now & the one thing I see the MOST is Police, government & company cars that IDLE for 6 to 8 hrs per day. I was actually sued by one company for their engine failures & upon court date I had accumulated 1000s of pages of court cases & DODGES own internal emails to Prove it is DEFINETLY a MANUFACTURES problem & DODGE was even questioning themselves if they should assume responsibility when supplying FLEET vehicles. I won the case & won a counter suit for slandering my business by pointing the finger at me.

Eric does a better job teaching econ 101 then most teachers...

Meticulously removing the hose clamps, then cutting that hose. Gets me every time ;-)

We have one of these in our brush truck on the fire department. It's a ballsy son of a gun even with 300 gallons of water, 25 gallons of foam with a 6" lift and rolling on 35s.

Damn. You know you're doing something right when your video has been up for 13min and already has 1.7k views.

They might not make as much power, but this is EXACTLY why I like the old school Small Block Mopars!

Im 61 years have worked on alot of older motors. Some how watching you tear these down is giving me a good idea of what motor I want in my next truck. So on Saturday night a bag of popcorn, cold Coke and your video I'm good to go. Loved the car crushing with the rubber tire loader

My Saturday is now officially complete. Please please do a Ford 6.7 Powerstroke

I ABSOLUTELY LOVE when you take the clamps off carefully and then cut the hose. Even when I know it's coming, I laugh out loud. Keep doing what you do man. Love the content.

I own a 2022 Ram 1500 with the HEMI. At 32,000 it started to develop a cold start tick that went away within just a couple of seconds, as soon as oil pressure came up. I immediately changed from the recommended 0w20 to 5w30. The cold start tick immediately went away. At 49,000 miles now, the cold start tick has not returned, and surprisingly, the fuel mileage has not changed. It is still 21-23 mpg on the highway! The moral of the story is use the proper weight oil, and don’t let the truck idle for any appreciable amount of time!

My internet connection died yesterday and my first rection was "How am I going to watch this weeks teardown?". I'm in the UK and I always watch these teardown video's before I get out of bed on Sunday morning. Thank you for sharing.

This is my Saturday night special.

My heart skipped a beat when that motor jumped on the stand! Its a very decent core. The machist can take a few mils off of the crank journals and the end user can just go with thicker bearings. There's some very decent parts on this engine and im glad that it turned out well for you. Always glad for the entertainment value as well. Cheers!

That Hemi engine had enough buildup that it was obvious that the oil was neglected to some degree (yeah, we've all seen worse). This channel has made me into an oil change fanatic. It's a pretty reasonable cost compared to a new engine.

Those 6.4 truck engine look to be pretty well made for a stellantis product.

14:08 Did anyone notice that when Eric threw the head gasket into the air, it just vanished? It never hit the ground again. 😮 Maybe he threw it so hard it went into orbit. Thanks, Eric. It's not like we have enough useless junk just floating around up there. Now you have to add to it.

Common failure point. The valvetrain is at 180 deg instead of 120 or 90 deg in other v8s and there's no lifter valley to provide lubrication to the cam and lifters so they will sieze up and fail over time. The LS has a similar problem. There was a very good reason for the lifter valley in traditional V8 designs. Modern engineers seem to have forgotten that's how you lube the lifters and cam.

Another entertaining teardown show in the books. Appreciate you man.

Love watching you tear these down. I’m actually finding myself knowing what I’m looking at under the hood! And your sense of humor rocks! Thanks for doing what you do!

Bigger HEMI size, same HEMI issues. Lifters strike again.

I’ve been watching for a while now and I’m always watching with an eye toward simplicity and reliability. This engine seems like one of the most straightforward designs that I’ve seen on the channel while still making serious modern power.

I like the subtle comedy of going through pulling the clamps and then just cutting the hoses. Solid.

This video came out as I was literally putting back together my 392 6.4 Hemi last weekend! Thanks for the teardown! It makes me feel much better about the state of my 6.4 ;)

My heart sank right along with yours seeing that bearing.. hope the crank is salvageable. Great video as always man

This popped into my feed after refreshing for 5 hrs after work! It just popped up 9hrs after you released it you tube needs to get better!

Another great video Eric. Thanks for the info. You and your family take care and be safe.

I'm just one of those YT observers of videos like this. It's part of my affliction, these fascinate me. Always have. From when I was 14 and putting together a small block Chevy from a box of parts, to my last days as a GM tech and later as a machine shop guy. Interesting that so many late model vehicles have lifter issues, rockers too. Might come down to the increased recommendations of oil change intervals. And we know many owners don't follow them. Although this Hemi was rather clean inside, His suggestion about the idle issues and lubrication might be right on. Thanks.

Good evening Eric. Another exciting Saturday night with the master of breakdown.

My surprised face when I saw that the lifters failed: 😐 It’s amazing to me that people still buy these. Maybe they take comfort in knowing exactly how and when it will fail? Maybe Ram should start offering a spare engine in a crate as an option at the time of purchase so that buyers can just finance the price of a new engine in their new vehicle loan rather than having to pay for it out of pocket a few years later.

Finally, someone stating facts about why the lifters fail instead of just jumping to an uneducated opinion blaming the MDS! The manual trans HEMI's also had this issue.

Another awesome video to wind down my crappy day.

Eric, thanks for the tech tips. Always appreciated and a big part of why I keep watching.

I LOL'd for real when you cut the hoses after taking the clamps off. Thanks Eric.

Thoroughly enjoyed this teardown

Good evening everyone. Another great video.

This issue persists till at least the 2021 models. Cam replacements are often and expensive enough that its makes more sense to replace the engine with the Jasper modified 6.4, with the oiling problems resolved. I see this issue at 60-80k miles on all of the ambulances I maintain and is from idling at 20-25psi of oil pressure. Our solution for the time being is 15w40.

Why is this so gratifying to watch?

That green and black vibration dampener puller is "the right" puller. Remove the hook pins, place the hooks facing outward inside the small holes of the dampener, reattach the hooks to the center, and pull. Thank you for the Hemi teardown.

I am on my 2nd 6.4l work truck and the engines have been very good. 2018 is about to hit 200k miles (hard work miles) and now in a 2024 just hit 12k miles. Transmission in the 2024 the 8 speed is much better than the one on my 2018 I can say that much. Sad to see them go away.

I crank mine in flood mode because my 6.4L sits a lot. Oil analysis came back excellent with 106k miles on my 2017.

Excellent video. It gave me a nice tutorial on the engine in my truck. Thanks!

Love your work Eric.

Chrysler put out a bulletin a while back to check the VVT solenoid for metal shavings. If it's clean you are safe to replace cam and lifters, if it has shavings it needs to be rebuilt or replaced.

Change your oil pump to the hellcat model but keep the regular spring to maintain the normal pressure. You will get better FLOW.

Good call on the mechanic who pulled it

Love your videos. Keep up the good work

Great show!

Very enjoyable, always a good time

cool to see ya get an engine that you have never had before hope you make $$$ back on the parts still learning new things every vid thanks sir

I can't believe it's a 6.4 hemi 2valve with two plugs per cylinder

Good morning from a sunny South Africa. Another excellent teardown. Hopefully the crank and block can be re-used. 👍

After our catastrophic failures with Fords, we've been shifting our fleet to Rams and we have five 390ci (6.4s) and have tore them all down and replaced the oil pumps with Mellings 10452, so far 2 of them have gone over 170K after rebuilt no issues, always wondered if this could be the main issue.

Great video as always Eric. Would love to see another Ford 3.5L V6 teardown!

Take a closer look at that ProTec "Wix" filter. That brand consists entirely of Purolator filters with "Wix" stickers on them. The same goes for "Bosch" filters. The ProTec PXL57060 and Bosch 3334 are both based on the Purolator L12222. I think the Quaker State QS45518 is also the same filter, as are some store branded filters.

I was really surprised to see that main bearing damage. Even more surprised it didn't damage the crank too bad or spin in the block.

Had lifter failure in my 2014 Ram 2500 with the same engine. Glad I replaced it with a new one, but ouch on the replacement cost. Thanks Eric! Mine had the failure at 117K in 2023, I treated it right but it was a used truck when I got it in 2020 with 77K on it, so didn't have a history on it. Seeing what had happened to the main bearings on this engine makes me think about how bad the ones in my failed engine might have looked.

Blue to the rescue!! 10:52

Another great episode

O man, I came within a few moments away from. Buying a 2500 with this engine

Great video. I've been hearing thru the Hemi community that if you change the brand and viscosity of oil early enough it solves the "Hemi Tick"

More like this, please. BGE blocks rock

Ive been waiting for one of these forever! Just to chime in, the splash lube was a myth started by uncle tony because he thought the lifters weren't oiled on their own, he assumed they relied on splash lube, and the internet ran with it. But the lifters have a direct oil path through the rocker, down the push rods to the lifters. Chrysler's issue with lifters has been an ongoing issue, just like GM, because the design is picky. Like you know, Pushrod V8's at modern tolerances HAVE to have good quality CLEAN oil. the lifters have gone through numerous redesigns over the last few decades (indicated by the last two characters). AA is a first design, AB is a redesign of the part, AC and so on. I believe the lifter in this truck was an AA, and the part is now on an AD redesign. So overall we've got a few issues going on. 1. Quality control issues with cam hardness and lifter tolerances 2. Maintenance intervals being taken too far, and 3.the EVIC not properly taking idle time into account for oil change intervals. The 6.4 Hemi has been out for 10 years now, and the 5.7 over 20, if we had a design flaw on our hands, we would have almost every single truck fail by this point. But ive seen these trucks with literally thousands of idle hours on them. My personal truck is a 21 2500, with around 1000 hours of idle time. If you want them to last, change the oil often and you'll be totally fine. They do break, just like everything does, but they're great engines. All cars suck.

double wrenching on a snap-on reversible! That lifetime warranty coming in handy eh?

It surprises me that the 6.4 Hemi can make over 400 HP with exhaust manifolds that look so restrictive.

Really miss a good teardown with carnage, but glad to see you got a build able shortblock to recoup your investment.

The good ole hemi tick, been there done that.

I’m glad I bought my 2500 with the 6.7 Cummins so I don’t have to live with HEMI regret.

You just zipped the exhaust manifolds off no problem, so LUCKY!! 😥 So many Hemis have broken exhaust studs.

The crank is machinable. Use a tripod style hone to hone the cylinders, not a ball type hone. The cylinders will clean up using a medium grit stone. New cam is needed, as you said. Heads look good, but I would get them faced to be on the safe side. You can turn that into a ten k engine with no problem at all.

I watched a video on RU-vid from this guy who with is or was a Mopar tech and owned/owns several hemis and he has swapped out the oil pumps on on his and explained why. He showed that after a certain year the hellcat oil pumps which are I believe 20% larger capacity pumps can bolt right in and fix low oil pressure at idle which he claims is the biggest reason for the lifter failures and also comes up with a fix to still allow your MDS system to still work with the higher oil pressure and not throw a check engine light….. I’m sure a quick search with find his videos.

the size of that front cover is insane

The MDS kills timing chains. Light oil kills lifters.

He is right about the cams. I look at them frequently with service contract claims. It is as though it isn't hardened steel.

I have to say, those intake valves were some of the CLEANEST I've ever seen on your teardowns! I was expecting soot and gunk, but I got shiny and clean (except for the one that had the water stains from sitting: what do you expect from a core return?!). I'm glad Blue got some use on this one. It was coming apart so easily that I was afraid he might suffer from FOMO. I haven't seen a Ford 2.3L EcoBoost out of a Gen5/6 Ranger yet. Are they really that much better than the 1.3L? Thanks again, Eric, for taking the time to teach us and make us laugh at the same time!

I was glad it wasn't worse off. There are some nice design features in that engine, lifters not being one of them.

Chrysler could just install some extra nozzles on those piston oil squirters that fog the cam and the underside of the lifters with a light mist of oil, and would probably go a very long way to solving this problem.

here is a like and i highly recommend this channel thanks

I own a 2009 hemi 215k on it. I was warned when I bought it not to let it idle for very long. I do not understand why dodge doesn't have this motor programmed to bump the idle after a designated idle period. WE have computers on board that could do that.

I actually was impressed with this engine, except for the lifter problem getting proper lubrication, it was better that expected. Timing area was way better than a Ford with 2, 2 mile long chains and guides, not a big fan of that. Also, not a 2 piece block like some of the European models, not a big fan of that either. Great video Eric, I enjoy these every Sunday.

Great video.

The first hemi I saw was 2004. I was in Atlanta at the time . I put 100,000 miles on it and sold it. I will admit it was ticking at the time. The damage you saw tells me you are right. I bet it sit idling a lot. I have a 2012 5.7 now with only 104,000 miles and going strong.

Cool hiemiroid tear down!!

Our 2019 6.4l plow truck idles alot. 10,000 miles. 1700 hours idle. 1200 hours driving. Its missing on 2 cylinders. It has had only 3 oil changes.... My 2020 5.7L 1/2 ton has 45k miles and 300 idle and 1400 driving. Thats with 6 oil changes. Zero issues.

I like the video and WOW amazing TY so much ,,Keep up the great work

Great insights!

Actually, the afm causes alot of headaches with lifters, but usually it's the operators fault for extended oil change intervals, 3k that's it and only high quality synthetic oils throughout the vehicle! Also most engine rebuilders and machine shops recommend the hellcat oil pump or the melling HV pump upon rebuild, this seems to solve any further reliable problems for all the Hemi line. 5.7s get the HV pump and the big bad Hemis get the hellcat pump with afm delete and vvt delete. Problem solved👍

Great video

19:30 I believe they have released some updated lifters but being a 2015 model year it would still have had the old design.

In some service vehicles they put more oil in because of a long time running the engine on idle,but not everyone knows this.

I did not know these had twin-sparkplugs. Apparently you can learn new things every day. Huge valves on those heads.

This was interesting, paused the video when you were removing the exhaust manifolds and compared them with photos of the manifolds from my Jeep 4.7L manifolds, they looked very similar on both sides. 2000 vs 2015 vintage.

Such a simple engine for a company to really mess up!

Thank you for doing cars.
