Protect this man by all costs

I can't usually watch someone this long very well spoken highly technical point of view one of the best videos I've seen lately

This is not the first time I have heard talk about not letting a Hemi idle. Or not for too long because its not getting enough oil to the lifters. I'm glad I found this video by accident.

My 2015 Ram 6.4 got metal in oil at 98k. Bought a complete engine from Chrysler, cam from crane, upgraded springs Removed MDS, Hell cat oil pump and lifters, new radiator. After JMB in Hillsboro Mo. tuned it the transmission shifts correctly finally after 8 years. (6 speed). The coolant always stays at 215 degrees and the oil temp stays at 226 degrees. 9k miles so far so good. But at a total cost of $18,700. I hope it holds up. I do not want to buy another new truck. I still have the old motor and have not opened it up yet. Also this was during the time of parts shortage 6 months of waiting. Soon I will have dual exhaust and be able to enjoy the slight rumble of the cam.

I just put the hellcat oil pump on my 2018 Ram with 228,000km. I have MDS off so no code came on. I haven't had any engine trouble, and always used pennzoil Ultra platinum. Mechanic said it was the cleanest 5.7 hemi he's seen. Hoping to take this engine to 500k. Thank you for dissecting this topic so miticulously and sharing your knowledge.

Great video ! I have been following for years now, shortly after you started this venture. Glad to see you providing fantastic info, not just guesses.

Never knew of this issue until it happened to me! I am fairly mechanically inclined and usually have at least some insight into common problems on common vehicles. If you start getting this specific lifter tick, don't wait! It starts as a common lifter tick that progressively gets worse. Mine was slow enough that it made it hard to notice it worsening! Im stubborn and always want to fix car problems myself. That in combination with the problem being on my daily driver, just ended up costing me more in the long run. Wish i would have seen this video a year ago! Awesome content! Very informative.

This is an absolute CLINIC, my man! I love it. Thank you so much for sharing your knowledge with us.

Is this like the ONLY video that addresses a solution to this issue? Well done and THANK YOU!!

This was a great walk-through on your troubleshooting process. I'm on my 5th gen3 hemi and thankfully never had this issue but very commonly reported on lxforums over the years

THANK YOU! I've been having the issue for the past couple weeks ever since I installed a 6.2 oil pump. I could not find anything definitive after hours of research. You came In clutch with changing out my cam and lifters on my 5.7 and you came in clutch once again.

All that I can say is " AMAZING EXPLANATION ", you are not just smart and logical but are excellent teacher. Keep up the great work Sr. Thank you so much

Just watched your budget build up series because I was debating pulling the 6.4 out of my challenger to replace my cam next weekend. You made it look easy inside the care. Now I am finding this video, from TODAY after I learned of my lifter failure lol. Oh boy. Thanks for the vids.

Great video that condenses previous videos and updates to the current time. Thanks for putting the work into this for our community. I plan on putting a 5.7 in my 58 Plymouth... With the pump upgrade and higher quality cam/lifters.

I found your videos after developing the lifter tick in my '19 Pursuit. I replaced everything and did the Hellcat oil pump as well and left MDS intact. I couldn't find a 7.4k resistor and used a 7.5k and wired it in last night. The MIL didn't come back on and I believe the MDS was working as my mpg on a route I drive daily increased from before I added the resistors. Thank you for your videos and help!

The best diy presentation I've ever seen. Thank you !!!

Thank you. Completely agree as a mechanic who built couple hundreds of Hemi engines. I have an engineer mechanic background and could not add anything, at least now.👍

😊Great info again. I had to replace my cam, lifters and pushrods at 192,000 miles. That was 29,000 miles ago. I had the hemi tick, but when I started having misfires, I took care of the problem in my garage at home. I bought a Hellcat oil pump after listening to the info you provided based on your many years of experience. I too have had the recurring PO524 code despite excellent oil pressure(too good for the ECM). I will follow these instructions so I won’t have to keep deleting this code to use the MDS for my long drives to work. Thank you for all of the info on this topic!

Had a 2014, 1500, work truck with the 5.7 lifter & cam failure at 176,000 miles. It was driven hard by many employees with a poor service record and half it's life was spent idling in the oilfields. I just bpught the 2023 scat pack shaker 6.4, I have already got 9200 miles on it. Hopefully if I keep it one day I can have the motor built with forged pistons, a lot more radical cam & lifters, and some lively tuning ! Nothing too crazy just a step up on the performance ladder. Your videos have been very informative and greatly appreciated.

Wow was listening to during work and it’s great to have someone who is very informative and answers almost every question that pops to my head. Thanks for all the videos I subscribe and watch all new vids now , they all great man👍👍

This is an outstanding development! I can’t thank you enough for the effort that you have put into the tick issue. I have been through this, replaced the cam and lifters, followed your advice and upgraded to the HC pump in my 2012 R/T. The P0524 error has been plaguing me as a result. I installed a code reader and just keep clearing the error as it comes up. I will definitely be putting the in-line resistors into play as soon as possible. Thank you so much for all that you do. 👍🏻👍🏻

Very good deep dive into this issue. It all makes sense with supportive information, and it as cursory or dismissive as others.

This is one of the most well put together information videos on this subject thank you for youe clearness!!

Glad you explained difference in High Volume Vs. High Pressure pumps, I've heard those called different like that but did not know why. And seven quarts is a LOT of oil! Some people don't like the AFM on GM vehicles, they think oil sits in there and bakes since it isn't constantly flowing.

Extremely well done video. Thank you for your insight and research. I learned a lot! My 2015 Challenger pretty quickly developed the issue and had all the lifters replaced (but not the cam) under warranty in 2017. All this time I thought the newer parts were the cure! It's worth mentioning that the first failure was at 15K miles and now at 65K, it's still totally silent.

Converted the 5.7 EZH to an EZC in my '15 300s. Planned to install 6.2 lifters, but they are indeed the same part # as a 5.7. It runs great, and still obtain 22mpg at cruising speeds.

*EXCELLENT* video, thank you. Very very simply explained, and great level of detail.

This is truly an awesome video! It's amazing me sitting on my couch can learn so much about an engine in 15 minutes! Thank you for the video! I am looking ti buy a truck soon and saw one with this engine in it.

Great info. I used the Hellcat pump on my 2014 Ram after I did a cam/lifter replacement and I have zero issues.

I have a 2013 Dodge Durango Citadel with almost 50k miles. I ordered the Hellcat oil pump as soon as I saw your test results and just installed it. I will go further eventually but I think for now I should be fine. Thank you so much for this incredibly valuable information!

Great video dude !! Your explanation was spot on. I have a 2012 Grand Cherokee 5.7 hemi . Mopar had to replace the engine at 98,000 miles because of this. LI’m one of the fortunate ones that have a lifetime bumper-to-bumper Mopar warranty on my Grand Cherokee. At this point I might just go ahead and install that hellcat oil pump because I plan to keep the car for a long 😊 time .

I almost left the first time you said "gallery" instead of galley. I am glad I stayed for your incredible video. You really made excellent points and were very clear and concise.

This was absolutely awesome, thanks so much for taking the time to explain this 👍😁

Sounds like the similar issues that Ford experienced with their 4.6 and 5.4 engines. Senior Ford technicians, like Fordtechmakuloco extended the life of those engines with installing the upgrades lifters, rocker arms and Melling HO oil pump. In addition, the timing chain guides and related components. The installation of this Melling HO oil pump. The engine oil pressure increased slightly, less than 10 psi, but the flow of oil was increased to to the high output of the oil pump. Excellent educational video!

Facts. The frequent oil change interval is absolutely the best way to prevent wear / failure. Our 2007 RAM 2500 with the original 5.7 Hemi has 150K on it and we had to recently swap the oil pan (due to rust-through thanks to the midwest rust belt doing its thing) & windage tray/gasket. The internals looked fantastic and not a single tick in 16+ years of service due to oil changes being done every 3000 miles. 50 oil changes doesn't seem like much of a price to pay to avoid issues like engine component failure at bay. Cheers!

Very informative as usually. If we didn't have you, we wouldn't have the insight that we do. Good job brother.

Excellent breakdown and discussion on this issue. I watched your earlier videos where you determined that the HC pump was the way to go which prompted me to order one and install it on my 19 5.7 I just put into my 71 charger. I need to order 2 more, one for my 14 Ram 2500 and one for my 10 Challenger RT.

Totally awesome.. much appreciate all your research on this topic. So I read a lot about this topic and on my 2014 Ram 2500 6.4 BGE the oil type mattered as part of my warranty. So Pensoil 0W40 synthetic it came with is the only oil that has been in the engine from day one. I allways change my oil at 30% which is between 7000kms and 11000kms. I worry about idle times so get into a cold truck after 5 minutes...but I have wolverine heating pads on my oil pans with a timer to turn on 2 hours before the truck is started. Living above the 55th parallel I see a lot of Hemi tics and I'll say idle time is number 1 but poor choice of oil and lack of maintenance is proff too. 😊

I’m glad I found your channel. I just purchased a 2012 charger ex highway patrol car. It has the lifter noise and misfire. So I’m adding a comp cam and lifter. Along with exhaust mods.

Melling High-Volume Oil Pumps M452HV, claimed 20% more volume. I enjoy your videos.

I don't think there is another video like this on YT, anywhere!! Thank You!

Great educational video. As I listened to explanation on oil pressure/volume & error codes I kinda anticipated the oil sensor needed to be re-ranged or a different sensor such as on the hell cat engine needed to be installed. The voltage bridge was brilliant but I though the low end readings would be 12% lower now too. Being an old insrrument/electrician journeyman have seen field issues in instruments due to interference of all types from electrical induction to mechanical vibration, nicked cables when pulled in conduit. Anyway, having an 05 1500 with 5.7, 118k miles I have heard a tick now and then but now has quit. After changing crank sensor many codes have dissapeared fuel mileage increased, engine runs well. Thank you for your explanations & time putting together video. Most appreciated & subscribed & forwarded to some other 5.7 motor heads. Thanks Bro!

I have a well maintained ram 2014. and with 260K kilometers i had an issue with cil.no 1 . first thought it was a misfire and changed coils , NO check engine light came on. then tested compression and only cil no 1 had a bad low compression. I took it to a good mopar specialist in the netherlands and they discovered a lifter failure and ate one lobe out of the camshaft. The bad lifter it was even twisted 90 degrees. now i have a rebuild engine with non MDS and new lifters and a stronger cam, a lot of new parts and a stronger oil pump. Idling for a long time in trafic is not so good for a Ram . i hope i can do 200k again. for the rest the truck has no problems. Thanks for the informative video!

The only Hemi advice channel I trust

Great Video, very informative. I’ve been keeping up with my oil changes regularly and I currently have 60k on my 2019 scat pack charger. If I do run into a lifter issue I would definitely upgrade to the hellcat oil pump along with changing out the bad lifters and cam shaft. Thanks

Who else touched their screen and thought their screen was cracked when you went to your white board!? Lol I love your videos! Thank you so much for all your knowledge. You’ve helped me repair my own Lifter / Cam swap.

This is the most informative video I’ve seen in KZfaq. Thank you

Props to you for taking a deep dive look into this. So much speculation, I appreciate a your level headed facts based approach.

You should be an instructor, you explained it extremly well. I was a mechanic till 2006,I don't even own anything with Hemi engine but was curious about what you have to say and I'm very impressed with the information and the way you explained everything. Thanks for posting.

Thanks for this clear summary and update. Still loving my 2019 Scat Charger!!

I have a Ram with the 5.7 Hemi so I was very interested in this awesome and informative video. I change oil at 5000 or before and it runs like a top with no unusual noises but I also use a premium engine oil.

Re: Hellcat Oil Pump.... high end pressure outside MDS acceptable range. If we deceive the system by modifying the signal we have neglected to determine if we are going to negatively impact the MDS sysem by exposing it to oil pressure above the spec'd range. It seems better to very if whether the MDS system can tolerate the range and to edit the range in the PCM parameters if possible or install a pressure relief valve in the oil pump that dumps excess pressure back to the sump. Really appreciated this video!!!!!

I agree . More frequent lof services will do wonders! I worked for years in a dealer service department. Oil life reminders are the worst. People will always push them even further. Oil is cheap! Change it before it tells you to. 3- 5k no excuses!

A most informative video. Nice to know that mds is not the real problem. I change the oil on my 2015 300 hemi at 5000 miles or less and use synthetic oil. I doubt I will go the hellcat oil pump route but it is nice to know there is a preventative procedure available. You explain things thoroughly and clearly. Thanks again.

Brilliant. Thanks for your videos. I've had a lifter failure on a 2013 5.7 in a Ram truck. I do my oil changes religiously between 3500-4000 miles but I did idle the truck a lot. Winter in Appalachia.

Thank you. You have the best explanation I've found so far. Very informative!

Thanks for the great video. Since I bought my 2022 PW, I've been following the advice in your previous videos. Oil change at 1000, 5,000, 10,000 miles. Minimizing my idling. Using very high quality oil, Pennzoil Ultra Platinum. Once out of warranty, I'll see about doing the oil pump upgrade.

Your concerns regarding the oil reminds me of an old 6 cylinder 2 cycle navel diesel. It had a visual oil channel on top of top of the engine. Before starting the engine, you had crank the manual oil pump handle until you see oil running through it. Then, you count 100 cranks before starting the engine. Oh, this engine was so old that they used 6 propane torches that were mounted on a swivel to preheat the cylinder walls. This engine was over 75 years old and had never been rebuilt!

Thanks again for some amazing information! Keep it up!

Hi. I'm from Poland and here this engine is not as common as on the continent, which is why most people succumb to stereotypes rather than delving into the topic of the MDS system, which is considered to be defective. No one could answer why it was so bad. Initially, I thought it was a matter of poorer material of the pushrods, because in engines without MDS the effect was similar with damage. Thank you for such a sensible explanation. Finally someone wanted to delve deeper into the topic.

I believe it's a combination of factors. I believe the fundamental design of the block plays a role and the change for VVT took something that was marginal but working to something that started to fail. The oiling from the lifter bores at idle is not going to splash much onto the cam. As RPM goes up the amount of oil from the crank and lifters splashing would go up and be sufficient. Lots of great info though.

I agree with many that the push to thinner and lighter oils is part of the problem. While many will disagree with me, I have found that using a heavier weight oil helps. In fact, I have solved more than a few problems using a heavier weight oil in many cars and trucks. Personally, I use 15W-40 in most of my vehicles and the results have been excellent. 10W-30 is another good choice for many. Whenever an up graded oil pump with more volumn and another 5-15 psi is also a real help.

Great video. For years I have used resistors to fix pre 1989 gm gauges. Gm used to put resistors right on the back of the gauge itself.

Great video with lots of good information! Thanks Brother!

I suggest oil changes 3000-5000 miles at most, or every 6 months, whichever comes 1st no matter what any factory suggests.....that gives u a chance to inspect the the rest of the engine bay, fluids, suspension, etc and gives u a better idea of what is going on with your vehicle...I think anything above 5000 is asking for problems..great video bro...

Great video, lots of great information. I have an 08 Charger that I am thinking about upgrading the cam and lifters to the 6.2. I will put a Melling pump in at that time also. I am currently getting ready to change a wiring harness to solve a problem with the MDS showing an open circuit and not functioning. I have it disabled in the tune, but want to get it working again.

Outstanding video! Thanks for the thorough description and solid solutions.

Absolutely a GREAT Video. “Thank You” for such in-depth info and logic, it is appreciated….

Melling also has a newly released high volume pump for the later model engines, part number M452HV which has the same displacement as the hellcat pump.

Living in Los Angeles driving city streets to work and back , I have no control over my excess idle time…stoplight to stoplight. 40 minutes to go 8 miles. This video was the sharpest, most data driven explanation of why the Hemi tick (cam/lifter failure) happens and how to reduce the likelihood or potentially prevent it altogether. Thank you!

I have a 2010 Challenger RT 6 speed manual and I have a 2014 5.7 hemi block from a Charger that I plan on building for my 87 Dakota. When you first put out the oil pump video I bought 2 of the Hell Cat oil pumps but I haven’t installed either of them yet.

Both my hemi-powered Mopars are performing flawlessly, with 130K miles on my '12 Challenger R/T w/5.7 hemi & 6 speed manual trans, no leaks, oil usage, or ticking other than normal injector firing noise, same deal with my '14 Chrysler 300C w/5.7 hemi, excellent performance at 91K miles and no "tick" either. I use high quality synthetic oil in all my rigs, it has kept them running very well and change oil & filter @ around 5K miles or 1 year. Thanks for a great video!

Very educational video. I have a 2020 1320 and I change the oil every 5k/6months, whichever comes first. Oil life tends to be in the single digits at that time. I use the recommended pennzoil too...Hoping for the best. This car is actually my daily driver, with around 10k a year. The only oddity I find is the oil filter weeps a bit. I use the 899 filter and tighten it to spec. I wonder if that happens to anyone else. The engine doesn't use any oil either. I have another year and 9 months of powertrain warranty left though.

My respect for your knowledge and advice grows by the view. Thank you sir! Planning on upgrading my 2013 Ram 1500 to Melling HV soon

I love watching this channel, getting me ready to build my 300 srt wagon

Awesome info as always! 💪

I did lab samples of QSFS 5w-30 up to 9400 miles and it easily did it. PUP 0w-40, Redline 5w-30, and QSFS 5w-30 should all allow 10K oil changes. My environment is severe interval recommended also. Tuned engine idle up to 800 RPM also so it never goes below 40 PSI now.

My Pop had a 2005 SRT 300, he loved to pull off the road and talk on his phone. Around 109 thousand he asked me to look into this squealing noise,it sounded like a hamster wheel that needed grease. I told him the bad news ,the lifter. I swapped a OEM take out cam from a 06 6.4 . The old one was a billet steel core,the newer was a casted steel. We think the lobe was soft and killed the roller . It's a lot of work getting to the point of pulling the cam. 12 + hrs to complete, Dodge parts guy said 11.5hr ,so I was happy that I came close on my first hemi cam swap Great technical info ,wish I had it back in 2010 !

Great advice, Thanks for all the info👍

Thanks for making this video its very educational

The thing that worked for me was royal purple engine oil and a mopar filter. Truck had 147,XXX 5.7L hemi no knocking. challenger has 152,XXX 5.7L hemi no knocking and it sat for over a month. Fired it up no smoke no knocking. Both are 2013 year models

Good Information! I have been watching your videos and believe the HV pump is one of the fixes for sure. The problem is no one wants to install it. I am pretty handy but a real world truck install sure would be helpful for many of us!!!! I also believe the new SN oil standard (year 2010) coincides pretty well with the model year 2009 5.7 Hemi. They kept the same amount of phosphorous (hence ZDDP) as the SM standard, but based on the SN standard description, made other changes that surely required more detergents / cleaning agents. More detergents will wash the ZDDP off and reduce its effectiveness. No ZDDP (effectively) = no protective barrier.

Man that's a great video very informative keep up the good work i learn alot from you and its helped me in the past and now i am back for lifter failure thought it was exhaust leak on my long tubes

I bought a retired Idaho State Patrol Charger, bought it from a auction, bought it on line. Drove from Washington state, they drove it around and I heard a tick! I pulled the cam out, one lobe was wasted, had another going bad, but it wasn’t the lifter, it was the hardening on the cam wasn’t good! Spinning at 1,000 revolutions per minute, I’m sure the cam lobe started destroying the roller first, then the lifter destroyed the lobe! The one lobe was getting rough, the roller was still pretty good!

Great information! I wonder if the upper psi limit was set to prevent damage to the MSD system. Thoughts?

Excellent educational video. The only thing I recommend is you expand these discussions by doing 1-2 Live KZfaq sessions so we can all group collaborate in a Live forum. 👍

Great break down here man! I came across your video while searching for oil cooler, I’ve got a 2014 2500 with the 6.4 Hemi with 108k miles. My plan it to install a hellcat pump next. It’s a solid truck, I always drive with MDS off by gear limiting the trans. It works well. I also don’t let it idle, once the idle comes down after a cold start I leave the driveway as a way to keep it from idling for too long… thanks for making this video!

Just put a mopar reman into a 2013 ram1500 which did have a lifter failure at 112k miles (on a non mds lifter). And thanks to your previous videos I knew to install the hellcat pump when doing the job. Thank you very much for the help.

Wow, an automotive video that keeps it real and isn't trying to sell some miracle cure or expensive aftermarket parts. As an engineer, every word you said makes perfect sense, and I could not pick out one single word that doesn't comport with my knowledge, education and experience. The pressure vs volume, the voltage divider explanation are all accurate, and as far as I can tell, and the insight that the MDS and its attending block redesign was implemented in 2009 when the problem started makes perfect sense. The oil change interval advice and the extended idling caveat are both also dead nuts. You got yourself another subscriber just with this no-nonsense, anti-bullshit video. You earned it.

Thank you this helped me greatly. 2014 jeep grand cherokee 5.7L hemi 126k mile number 5 lifter. I did get the hellcat oil pump and swapped the spring.

Thanks for sharing your expertise and honesty with your awesome video. I learned a lot from it and know others will too.

Thanks for this video! How long have you been driving with the hellcat oil pump? Any other issues?

A lot of great information. The comment on switching up to a hellcat oil pump is interesting. As someone who has faced the dreaded lifter tick 3 times on two different trucks, I can safely say that part of the reason is the move to thinner oils. On pre 2009 engines, the manuals state to use 5w30 engine oil, but on my 2014 trucks, the manual said to use 5w20. This is only for better EPA ratings. GM has the same issue with their 5.3 and they too specify thinner oils. I believe the bearings are not getting the lubrication they need. I followed the manual and did the changes right to the letter and it bit me in the ass. That is why when the tick happened, I was puzzled. My brother's Durango had done much more miles and it didn't fail at all. Not a single issue, and he was sloppy when it came to maintenance. I noticed that the dealership here in Dubai does not use 5w20. They keep using 5w30 to every engine (despite what the manual says) that comes to them for oil changes. But they will happily sell you 5w20 when you're doing the changes yourself. There are those who have been using 5w30 / 0w40 engine oils on their Hemis and have never faced a single tick or issue. So my advise to any Hemi owner is to keep the oil change intervals short (like 4000 miles) and use a good 5w30 / 0w40 engine oil like Mobil 1 or Valvoline. If your budget can include Redline, use that as it is the best oil for the Hemi IMO. In my own reading online, it has been noted that Hemi engines respond very well to oils with a lot of moly in them.

Rebuilt my 2008 charger SRT8.... used cam bearings that had oiling trenches " grooves" that led to the oiling hole vs the OEM cam bearings that dont and used new lifters that had oiling holes vs the OEM lifters that don't and put a mellings high volume oil pump in it....

Your solutions are most likely right, a lot of engines these days both gas and diesel have oiling problems, mainly at startup. It's the manufactures way of getting their customers into new product

Great info. Super easy explanation. I don’t own a Hemi up here in Canada, but have and do own some Dodge products. I always tell people to do what most manufacturers say, (I tell my wife the same) get in vehicle and start it, then put seat belt on and adjust whatever you need to, turn radio on etc. Then put it in gear and go. Don’t drive like a maniac if it’s -40F, but start driving & tack it easy for a few minutes. The vehicle warms up way faster driving than idling.

Awesome information, thanks for the video. I always rebuild with a hellcat oil pump, but also remove the mds. This resistor mod is a lot like what Sonnex did for the 65rfe transmission, where they created a plug that works in line with the wire harness to fool the pcm to increase the transmission line pressure. Seems like this resistor mod for the oil pressure sensor could be created into a plug that would work in line with the factory plug.

Literally explained what was happening to my old 2014 challenger rt redline edition.

Hi Sky thanks for the videos. I cannot believe that it took youtube so long to suggest I watch this because this is exactly the type of content that interests me. You describe yourself but I want to make a suggestion: You're more than a 10 year Dodge tech you are an enthusiast! This is an integral part of the American culture missing from the new generations of technicians. Enthusiasm! Then, sharing your information to other enthusiasts. One question and concern I want to raise is that I feel lubricants such as motor oils may have somehow taken a step backward. I have experienced lifter failure on my LS7 engine. The roller scuffed on the cam lobe or the roller failed. The older spec gasoline engine oils may have some slightly higher chance of forming deposits and slight catalytic converter fouling but I am betting the reduction in zinc and other metalic anti-wear additives have diminished the effectiveness of engine oils. Thanks man!

About using a heavier oil weight, couldn't the thicker viscosity help protect the lifters? I'm not talking about the oil pressure at all, only the viscosity. The 5w-20 vs 5w-30 debate for the hemi has gone on for awhile, and when leaving out the oil pressure, studies have shown (for example, on projectfarm's channel) that the thicker oil can do a better job at lubricating. I know that there can be problems with the VVT and maybe the MDS with a thicker oil, but just for lubrication, what do you think about running a thicker oil?
