My 2005 5.7 hemi lasted 245k miles and failed in April 2023. It was still running good to its last day. Unfortunately the timing chain tensioner failed which allowed the engine to jump time and pretty much destroyed the valves and pistons. I bought a replacement from Jasper Motors with a 100k mile warranty. It's been great so far.
Lead - Thanks for sharing your experience. Sorry to hear about your 5.7.
Do you have the mds deactivated or not
And do you drive a lot of long distance ?
Because many say that with mds when it's active, the shut down cylinders starve of oil
You are correct with proper maintenance on those 5.7 hemi’s you can get 200k plus miles out of them, I have 212k and just now starting experiencing cam/ lifter issues in my 2010 Ram 1500. That truck has been rock solid, the normal wear and tear brakes, cv axles, etc. I’ve only changed one alternator, one fuel pump and I’m still on my original starter.
Sean - Sounds like you have an impressive 5.7! Thanks for sharing your experience.
Nice! What year? And what oil and filter do you use?
@@mtn-endeavors67 2010 Ram 1500 bighorn Crew cab 4x4 and use I royal purple 5w20 full synthetic, and I use mopar 899 oil filter.
MY 5TH GEN RAM 1500 JUST HIT 100K…..NOT ONE ISSUE….BEST TRUCK IVE EVER HAD….
Marty - Nice! Love hearing this.
I love the 5.7 Hemi. Take care of your engine, and it will take care of you for a very long time.
Joe - Absolutely agree!
How can you avoid the cylinder deactivation problem?
I've owned 8 Rams and have never had that problem. I know that you can do an MDS delete and get rid of it all together. It's pretty poplar and fairly easy to do. The lifter issue, I believe, is an oiling problem. Not enough oil is getting to the top end. I replaced the stock oil pump with the Hellcat oil pump. It's bolt on and pumps a higher volume of oil through the motor. I've never had a lifter problem. Fairly easy to do also.
@@JOEMASON-ql7gs ok thanks that’s what I figured cause in my experience it always comes back to lubrication on a generally good engine would you think lighter oil might help too?
I run 5w20. That's what the dealer recommends, but you are correct. The recommended oil does keep getting lighter, which helps with oil flow.
Very useful video, thank you !
Piotr - Thanks for the feedback!
I had a tick for 10 secs on my 2019 Ram. Yesterday I replaced a broken bolt on the muffler pipe. Right at the clamp before the muffler. Passenger side. No more tick… I was leaning towards manifold bolt. Exhaust pipe was the tick issue. Put your hand on it after it starts and you can easily feel the air coming out at the clamp.
R - Great diagnostics! Thanks for sharing your experience.
Well done and Thank You,
I Just picked up a mint 2014 Jeep GCL with the 5.7 Hemi with just over 150 miles on her.
Ray - Thanks for the feedback! Sweet pickup, hope it lasts you another 150!
429,000 miles on my 04 hemi.. never been apart does not even burn oil..mobil 1 every 3 thousand miles from day 1.. that is over $11,000 in oil changes. i could have bought 3 engines with .
Mark - VERY impressive! We love hearing/seeing this things go 400k+. Not very many of those on the road. This goes to show that it's all about how you maintain a vehicle.
Do yourself a favor and replace the timing chain tensioner before you have a sudden destructive failure. My 2005 model was running perfect and completely destroyed itself at 245k miles earlier this year. Wasn't burning oil or anything. Did have broken exhaust manifold bolts, but that's it. Tensioner failed, engine jumped time, and total destruction was the result. That tensioner is plastic with a metal chain riding against it. So it is definitely a wear piece that does eventually fail. Good luck.
Lead - Very true! Thanks for adding this insight.
My ram is junk
I hope I make it as far as u..My 04 is at 240 thousand miles on original engine and transmission and I'm still daily driving it! It's never left me stranded
Greet video very helpful!
A - Thanks for the feedback!
My son bought a 07 Chrysler with 120000 miles with a slight tick, switched the oil to Royal Purple and the tick went away, now has 350000+ miles and still no tick and it is an MSD engine. I have 244000 miles on my 07 ram 5.7 non-MSD engine, no problem and I recently acquired a 09 Chrysler 300C non-MSD engine with only 62000 miles, no tick. The main problem seems to be the lack of oil changes due to excessive idling and not accounting for it in scheduling oil changes and poor oil circulation because of the lower oil pressure at idle which I believe Chrysler opted for a higher volume pump to help alleviate the problem.
Stephen - Thanks for sharing your experience! This will certainly help future viewers.
Wow! This guy really knows his stuff! Great video!
Matthew - We appreciate the feedback!
He needs to check on spark plug change times!
@@johnm.harper77330k miles copper plugs (Champion/NGK) recommended on my ‘07 Ram, just like he says.
5.7 Hemi is one of the best engines on the market today. Every 5,000 kilometres I change the oil. 2023 the kinks have all been worked out over the last 20 years. 2025 there will be problems with the Ram new 6 cylinder turbo engines. Lots of kinks to work out. I will stick with my Hemi engine!
G - Thanks for sharing your experience! We agree with the next gen engines.
I'm at 278.000km engines been great. Pulls 19.5 bassboat. Where the problems are is tipm, fronts axles and rockers rusting. Forgot gas tank and fill tube. Nuff said. Forgot replaced starter.
L - Thanks for taking the time to share your experience! Sounds like you take great care of it.
Hey man maybe a selfish request here but I personally would LOVE to see your opinion on the best platforms for performance Cars, SUVs & Trucks maybe your personally ranking and understand it’s all your opinion but you know so much about these engines that I’m sure the community would like to see your two cents when comparing BMW’s B58s & N54s vs Ford’s 3.5L ecoboost & V8 vs Dodge’s 5.7L Hemi & Cummins … I currently own an N54 and looking to buy a second car to support the build whenever it’s under construction 😂 but really not sure what would be a good engine for a bigger car like an SUV? I’ve been looking at Ford’s 3.5L ecoboost in the Explorer & Dodge’s 5.7L in the Jeep Grand C or even considering getting another bmw and going for either an N55 or B58 SUV … In terms of performance potential, ability to rebuild(some platform are more rebuild friendly like the N54 that has so much information online on how to build them and lots of aftermarket support to buy affordable forged internals) and ofcourse reliability! Appreciate if you read this 🙏🏽
Bass - This is something that is actually in the works. Come New Years, we'll have different content such as comparison videos, mod guide videos, and more. We'll add the N54 vs B58 to our list. Make sure to stay tuned! Thanks for the support!
Just got an 04 2500 with the 5.7 motor was completely rebuilt about 30k miles ago and car was completely taken care of I’m hoping it lasts for a while
Tay - Based off of your description, it certainly will, so long as you take good care of it as well!
Seems like the MDS being the cause of the lifter issues is still debated. The other cause some folks suggest is lack of oil lubrication during idle. Thoughts?
C - Both can definitely be it. We would lean to MDS more often.
@@8020Media Some report despite "disabling MDS" they have still experienced lifter failure. Would be nice if there was a definite answer to this quandary!
Unfortunately, there is no finite answer here. All problems are not, and never will be, the exact same.
I think it is mainly poor oil flow at idle, and the fact that Mercedes directed them to have oil squirted to the underside of the pistons instead of the he cam and lifters.
And of course the refusal to change the oil enough
I have a brand new Ram with the 5.7 Hemi with 1100 miles. I already had to have it towed due to a MDS issue. Cylinder 6 misfiring, they replaced the MDS and now said the actuator is broken. I’m concerned there could be other issues as a result. Is there anything else that you think could have issues as a result of this type of failure?
HD - So sorry to hear about this.. That's rough.
Just get a cam and MDS delete kit
There is magnet debris collection underneath the MDS solenoids just sitting down inside MDS holes. Chances are it could fall into the engine and had nothing to do with engine functions. Debris collection magnet collects metal shavings while using 5w20. The guy pulled the debris collection magnet out and discarded it. The other Guy uses 5w30 full synthetic volvoline because his store sold out other brands and his cold climate. I guess he used 10w30 in the summertime climate. The clapping or tick is gone for used 30 weight oils. Running like a kitten. Like all engines you change oil if you drive nearly 3 months before 3000 miles. Doesn't matter what brands of oils you are buying. Still have to use MDS solenoids for MDS lifters and MDS camshaft functions for circulating the oil flow. Thinking about the debris collection magnet caused our confusion.
Nearly 200k on our family’s 12’ Hemi, runs great. We love our Ram!
Self Care - Nice. Thanks for sharing your experience!
I know this post is about a year old I live in the north east I have a 05 single cab short bed 123k miles truck not rusted but the oil pan had to be replaced because it was made to thin leaked pretty good now got the manifold leak on passenger side I bought tuned headers and nobody wants to fix it they don’t want to hang up the lift for a hole day
F - Sorry to hear about this. Thanks for sharing your experience.
Unfortunately, I just replace my Hemi 5.7 in a Jeep Grand Cherokee 2014 at 166,024 mileage. Vehicle was always serviced at Jeep dealer; regular oil changes (6K to 8K mileage).
Vic - Thanks for sharing your experience!
8,000 is too long, regardless of what marketing says. 5,000 - 6,000 would be better.
Chrysler 300 hemi haven’t change the spark plugs in 3 years lol only problems was cooling issues and suspension issues replace the fuel pump valve body intake gasket and exhaust manifold gaskets valve covers. I only hear the hemi ticks when the oil is low 😂😂😂 and I immediately change it. 5.7 hemi maintenance are not cheap
D - Thanks for taking the time to share your experience!
MY 2007 HEMI HAS 358K MILES STILL RUNING LIKE A CHAMP ORIGINAL ENGINE ORIGINAL TRANS
Anthony - Thanks for sharing your experience! Sounds like you've got a good one.
i tried ecoboost engines they are very good i have to say.
Loyal - Which EB engines have you tried out of curiousity!
Year of update intake?
David - What?
@@8020Media You mentioned an updated intake came ou on the hemi. What year did that updated intake come out?
2009
People just don’t change their oil and expect their cars to last 🙄
2 - Spot on.
You don't know your Hemi engine very well, spark plug change is 100,000 miles! I have a friend with 360,000 miles on his, no engine problems same spark plugs!
Bet it would run a lot better with some new spark plugs
100.000 miles before you have to change spark plugs, do your homework before giving out data!
John - We wouldn’t advise 100k miles. Especially since the recommended is basically half of that. But to each their own!
@@8020Media - That's what John was saying. The recommendation from Ram is 100k on the spark plugs. Don't know if it changed over the years, but that's the recommendation for a 2020 Ram 1500.
Our advice would be to follow what is in the manual. There are ranges since there are different variations of the 5.7 Hemi.
Should not go that long without servicing the plugs, regardless of what marketing says.
In most cases, service intervals are decided by marketing, rather than engineers.
