FAQ:
Cost: The heads were $550 plus shipping and there was about another $500 in other parts and gaskets. Time cost was about 4 days with 2 people cleaning every part and bolt.
Heads: It was a machine shop in Grand Prairie, Texas via eBay, seller name: headsonly, that the heads were purchased from. Listing Title on ebay: "DODGE CHRYSLER JEEP HEMI 5.7L V-8 REBUILT CYLINDER HEAD 2003-2008 ONLY"
They have a core return program where you give them a casting number and some info, they send you the correct set of rebuilt heads with improved valve seats, and you send your heads back in the same boxes with the return label provided. There are plenty of people doing a service like this so do some research and find a seller that you like.
Cause: This car was a classic case of cost cutting being the main factor in the valve seat failure. Making radiator end tanks out of plastic is a bad idea because they get brittle and crack with heat (this problem is accelerated with the desert heat where we live). So the radiator cracks an end tank on a hot day and the engine starts over heating very quickly causing the valve seats to drop. Don't think this would have happened if not for the radiator since the car had 207K on it at the time.
Thank you!
I just changed the cylinder heads on my wife’s 2011 Jeep Grand Cherokee Laredo with the 5.7 Hemi. In this forty minute video you showed everything that needs to be done.
Not only was this video easy to follow, but there were times I would wonder if I could complete this. I’d watch this video and my confidence would go up again. Until now, I’ve done almost everything else under the hood, but this was the deepest I’ve gone. All the garages quoted us $10k-$12k to get a new engine. For the warranty on a new or a remanufactured engine you need to also replace the cooling system as well as buy a new intake manifold.
Thank you again.
Bet it's not running anymore if u didn't shave those heads after taken them off
You should do this for a living. Very entertaining to watch actually. Good job!
Did this on my 05 Magnum almost 2 years ago. I used a head rebuilder out in Simi Valley and they included new head bolts, gaskets and a great warranty. The heads looked like brand new. Few pointers I’d add to your already excellent tutorial: 1)Replace those little O rings on the water pump hard lines. It’s EZ to do while everything is apart.
2) Check your pushrods to make sure they haven’t been bent by the force of the valves impacted the pistons. Again very easy while it’s torn down.
3) Getting the air pockets out of the cooling system is a pain. I’ve found the best way is to use one of special funnels that allows the air bubble to rise out of the reservoir. Don’t forget to use the bleeder port on the water pump when you add the coolant too.
4) Check your heater hoses! With these cars getting up there in age it’s probably time to replace them to avoid another overheating issue down the road...,don’t ask how I know this....
5) Consider replacing the motor mounts for the same reason.
6) My new water pump was purchased on eBay from a dealership and had a metal impeller. Mopar!
7) I used a engine support bar from Harbor Freight instead of a cherry picker so that’s another alternative.
Great job, thanks for taking the time to document all your hard work 👍
what is the issue with plastic impellers? I've seen plastic impellers used on heavy duty diesel engines without problems. is it a creep issue?
Just replaced water pump on 05 and no bleeder hole in new pump.
Now heater water has air in it.
Great video. This is to all you who ask way too many questions that are in the video, you shouldn't be watching this because if your attention span is so short that you missed parts of this great video, you certainly don't need to be working on an engine, especially this generation Hemi.
I agree to some extent. I did have to keep going back because this video is so information packed. Watching so carefully, I actually missed some bits of information he would be talking about. One thing I really appreciate is how he goes over all the fasteners, bolts, and connectors as he’s pointing out procedures. Some connectors are not always obvious, and when they are frozen in place it’s easy to doubt you’re doing it correctly. If you’re doing it wrong and you force something you’ll break it.
Lots of short bus window lickers seemed to comment on this video
Best engine rebuild video I’ve ever seen
Excellent video, I have a 2007 Durango with the 5.7 and over 170k miles. Nothing major yet. Thanks for taking us along on the repair, you made it look easy and simple.
Excellent job guys. I'm retired now but spent 45 years in dealer service depts and found your video spot on! I'm dreading doing my 5.7 Grand Cherokee Limited with 137 K, but better to change heads before the seats drop. I've already used a Diablo tuner to have the fan come on 10 degrees early, shut of the MDS, and put an 87 octane tune on. I get 16.5 - 17.0 mixed, which is 1.5 better than stock, plus more balls. Highly recommend turning off MDS since some research says it might be involved, although it seems yours was on non MDS cylinders. Great job, once again!
Wow by far the best Hemi how to video on youtube... i just bought a 2018 charger 5.7 hemi ..I hope i get 200k out of her like you did without major issues ..Extreme Heat can kill any motor Hemi or not
I highly doubt it. There was a major revision in 2009 that was supposed to fix the issue with many more small revisions since then.
@@cardesinr whats your opinion on a 2016 Ram 1500 5.7 hemi? with 60,000 kms on it. I just bought one but wasnt aware of this valve seat failure. does the revision you mentioned previously in 2009 apply to the Hemi engines in the Ram line up?
cardesinr How did you manage to get the valve cover bolts off the bottom passenger cover it’s a very tight fit any special tools? Or modifications?
I hope you replaced the lifters while you had it apart. Excellent video!
Great instructional video. Detailed and easy to understand. I am surprised that there was no visible damage to the cylinder wall with all those valve seat pieces bouncing around in there. You're lucky you didn't need to do a cylinder bore out.
Please note...I've had a set of ramps, in the style that you are using, in your video, actually collapse! Luckily, I was NOT underneath the car (A 1968 Dart), yet!....Stay Safe, young fella!
You did outstanding job, I noticed on your cap you are a veteran!, same here USMC also born and raised here in Houston, TX! I just now purchased a Dodge 1500 Longhorn with 5.7 hemi. One owner, also from a Marine! He had one head overhauled due to valve seat issue also. I know I will have to do the same to other head, engine has 133k miles, 2014 year. I was looking to see how much work removing heads, not to bad. But your right all due to cutting nickels to make more money. Its greed, and knowing most will take vehicle to dealership for repairs, or buy another from same dealership! Honestly you guys did a fantastic job with video and explanation, thank you very much!
Just curious, why would you still decide to buy a truck with this engine knowing it will potentially drop the valve seat and give you this headache? Why didn't you consider other trucks that are more reliable like a Toyota Tundra or even Nissan Titan?
Good job on the video. Can’t believe your block survived that piston breakage! It’s nice to see a diy’er solving problems in their driveway.
Very good breakdown on 5.7, did my cam and lifters 2011 Grand Cherokee, minor differences but the same concept, wish more videos were like this
Very thankful for this video. I'll be taking on this job soon due to the Dodge dealership wanting charge around $4500 🙄

So I was told bad heads and valve issues call for a new motor. Is this true or is there a possibility of new remanufactured heads like this video? Trying to see if a new motor is the only option. Pricing things out
@@BURNZ2ACRISP it depends it a valve seat broke a piston and destroyed the cylinder wall. A machinist will tell you the block needs to be decked but it probably won't. Again depends on the condition of your block. I can't tell you if it will or won't work for your car, you'll need to determine if your engine is to far gone.
Can u tell me how u installed the piston rings what was the orientation of them
When you changed the Pistons did you have to re time it?
What year is this magnum? I would like to use that type of coils can i use those type of coils i gave the rat nest wiring. Mines a 05 dodge magnum 5.7
You Sir.... Are An ABSOLUTE! Certified BADASS😎💪🏾💯, I Replaced my Wall Poster of Chuck Norris and Replaced it with your Channel Photo 😂. Thank you fr this EXACT Video of what I needed 🎉.
I couldn’t begin to thank you enough. I was contemplating how to double check my stroker build from my local performance shop and a camera through the spark plug hole is a great start. Thank thank you.
AWESOME video Sir! Excellent narration and some very good tips. Count me in as a subscriber!
Outstanding video from start to finish! Thanks for taking the time to film and post it
Nice video. Those cracked rods are WAY better than machined. Caterpillar started using them when I worked in one of their truck shops in 2006. Landed on this vid because I'm considering edelbrock heads on my 300
I.m in the middle of doing my jeep Commander , It's very important you'll have pieces of the broken valve seat in your intake manifold that will get sucked into the engine and damage the cylinders . Trust me they'er in there . I washed mine out with a degreaser and pressure washed it ,all kinds of pieces came out , small pieces will stick to the inside of the intake .
Great video, I will be doing this to my 300c it is missfiring on number 6, Very much appreciated this will save me a lot of headaches.
Great video! I would’ve liked to have seen you go further into the engine with the cam and lifters, timing chain and guides
Sir !! You are a Hemi hero! I am driving a 2005 Dodge Magnum with almost 300,000 km on it. I have to say your video was very informative and I could tell the level of professionalism was at the top. Thank you for making this video. I only have one question my Magnum has slight vacuum leak. I can’t find where it is. So I want to go ahead and take that air intake off. Do you attach the intake gaskets to the intake or to the Block? Thank you so much
There a rubber gaskets for each intake port. They are placed on the intake then you put the intake on the engine.
Awesome video man! This really helped me convince my dad to let me rebuild the top end on his 2011 ram 1500 sport 5.7l w 150k miles! Lifter went bad and messed up the crank
That's the hemi tick. You should watch some videos on it. You need a bigger oil pump
That's the best how to video i ever seen. THANK YOU.
extremely informative, very good
One of the best videos ever seen, when it comes to how too... 👍🏽
I'm halfway through the exact process. I'm doing all the pistons and rings since I'm in there. They're che as a set.
My 2011 Ram HEMI 5.7 at 93k miles broke a valve spring and my #3 intake valve hit the piston. Dealer wanted $13k to replace the engine. Will do what you did to save money. Thanks for the video. My only feedback is why didn't you replace the lifters and cam while you were there? They cause the same failure modes.
At the same job I need done what you just did on that Magnum
Great video! 👌👌👌 Question after 3 years those heads are still in good shape???
Just throwing it out there it's a tight squeeze but the fans will come out the top, I did it when my radiator cracked on my charger.
I’ve done it both ways but it definitely works best with the least issues to pull it from the bottom
Great share thanks
on a ram 1/2 the motor is under the firewall
Your basically laying on the engine lots of fun
Thank you for such a thorough video! I have oil on my number 7 spark plug and it misfired. I am wondering if this is part of the issue that caused it, or at least now I know how to take it apart to get a better look and find the problem.
Ever figure it out?
@@jsteez7656 Still diagnosing the problem. Luckily I have another vehicle to drive in the meantime, so I'm not moving too quickly on the Hemi, but I will update when I have more info. I think my next step is a leak down test.
Great job Radiator fan assembly does come out from the top also👍🏻
Great job with this video. Good explanation and great video footage to show the issues and how you fixed them.
Hey this video is real helpful,I live out Philly it’s so hard to find the parts I need to do this, because the dealer straight up told me I need an engine which they want $8000 for. I’m only 22 & I refuse to let my 06 charger 5.7 go to waste
Get rid of it dude,it's a POS trust me..I know they look nice,but what counts is whats under the hood and that 5.7 is a POS..25 years in the engine parts business..
rockauto.com for parts
I know one guy who has over 360,000 miles on his 05 Hemi Magnum. Mine I bought new only has 113,000 on it and I ain't getting rid of it. I love that car.
5.7L is definitely not a POS engine if you take care of it. The one part that cuts half the engine value is the damn cheap ass lifters they put in them. If not for those, with regular oil change these engines would be nearly unstoppable
Lol pulls up the purge valve "it's part of the emissions system or something like that" idk why I found that funny
Nice job and camera work - I wish I could give it two thumbs up. Well done.
Wouldn't be easier to pull the whole engine as a unit you are having to tear the engine apart anyway.
just asked the same question. hate doing inframes.
Very informative video. A couple of thoughts. The rear cooling passages are really caked. Same thing with the block water passages before you scrape the carbon off the pistons? Why are they this way when all the others look clean?
Great video. If I'm not mistaken that's a 3rd gen hemi so almost everything should be pretty similar amongst all 5.7.
PS they send me to right gaskets for my Subaru. Had to reorder too. Lol.
Awesome video. Thanks for all yhe great information. Mine is gonna be a pain because its in a grand cherokee and its 4x4 so everything from the bottom will be tough. I may end up pulling the engine. But I'll see how it goes once i get into it.
It's a Mopar thing... I've seen it many times... Usually from overheating. I suggest staking your valve seats so they don't fall out.
This is actually a common thing with Dodge,the valve seat issue happens on their 2.7,3.7,4.7,and 5.7 models..
@@QBN37 yup, I agree. I seen and fixed it on a Jeep. Best thing to do is stake the valve seats when possible.
@@StealthyWolfDaddyWerewolf how do you do that
Awesome video!! Explained everything in detail and some good time saving tips. Definitely giving me the confidence to try and do this myself, thank you:)
Good morning & friendly nice greetings from Bavaria ( Allgäu, Germany ) & me👋🍀🙂
Nice Video about the issue of lose valve seat rings & a great repair Guide, THANK YOU VERY MUCH for this 👍🙂
Oh mate, what a bad issue and damage of your HEMI in your nice Dodge Magnum, i'm very sorry about that, a sad thing....😓
And i'm so AFRAID about that my HEMI could also become this damage, especially it's the same 5.7 Eagle 3rd Gen. HEMI in the 2006 Charger R/T Daytona what i've bought 2 months ago with 132.000 or even 222.000km ob the clock. I've found it via Internet at North Carolina and imported it and it arrived me ~3 weeks ago.
And the Car looks great, especially for its age of 14 years and the mileage. I see the car was not used a long time, and the seller gave it away to the shippers without filling up the motoroil. And so the HEMI had Not enough oil and runned that time when it was in the way, in the vessel. Motoroil It was under the "Safe marking" at the oil Stick. I gave ~1.5 liters of Motoroil in it and then it artived the middle of the Safe marking. What a big shame for the seller i think! That's really really Bad i think. BUT, the HEMI runns quiet and very nice, so i really hope the low Motoroil didn't made any damage.
It's a beautiful Motor, i love it!
But now i've found some Videos of the issue of the loosing valve seat rings. And also about the HEMI Roller lifters issue what is also called the "HEMI tick" & now im very very afraid about that....
Especially because it's a 2006, it's a 3rd Gen. Eagle HEMI, with the mileage when these engine failures could be possible.
What do you think i should do now?
And could you Tell me about, what is the most often worn part at the belt drive for the wather Pump, AC and steering pump?
Because i listen a little "queeking" when the Engine is running what comes from this belt drive.
For your knowledge i'll be very thankful.
I Hope my english is good enough that you'll understand me right, but i think so😅...i'm a real Motor Enthusiast, and i Spend more than 17 years with Alfa Romeo Cars in Motorsport, upgradeing, repairing, working on it and so i know every Bolt & screw of these very nice Cars and engines. But American Cars, especially Classics, but even also these modern MOPARS with HEMI's are a big love of me /since i was Young, US classic cars are my big Love. And this 2006 Dodge Charger RT Daytona, a Top Banana is a big Dream of me and to own one now Made a big Dream true.
And at this time i'm fixing different things on it before i could Drive it.
And now, with the knowledge of these possible Bad issues im really afraid about that my new old HEMI Dream could get that....
I wish you a great day and i hope for a answer of you, THANK YOU VERY MUCH, Bye👋🍀🍀🍀🙂
The cooling fans don’t exactly have to go up through the bottom you just gotta remove the upper radiator hose and turn the fans on. It’s on its side it’ll come right up.
Wow! Since you mentioned getting two left head gaskets in your gasket set, I decided to go look at the one I just got in the mail from rockauto today. It has two left head gaskets. And the cylinder size on the gasket is larger.
That was a lot of work. Great info, and thanks for sharing.
Pistons install MUCH easier when you use a little lube. At my shop, we use Schaeffers Moly EP in an oil can and use that as assembly lube for everything but the cam.
Awesome video....great job on getting your hemi magnum back on the road again....
Having that many seats dropping at the same time it sounds like it over heated. Change exhaust studs and replace the valve springs. There are updated one's.
he says that
Excellent video. Thinking of doing this proactively in my 2005 300C
Looking to do this on My 2007 Chrysler 300C, 64,000 miles...same piston rear passager side...no compression, plugs covered with metal......Are you saying $1,000 dollars in parts ?
I have a question, you couldn't install the Oil pan with the gasket already on it. Or is there a specific reason why you had drop the oil pan gasket separately through the front to sit on top of the oil pan ?.
I was wondering also lol
One of the most informative videos I have seen thank you! DO you have a video of what is sounded like or how it was running before you performed the repair?
I can make you one LOL
Have you ever had problems with your PCM and had to replace it with an aftermarket one?
Having to pull the heads to get to the lifters makes a cam/lifter swap a pain. Not like the old V8s. But this would have been a great time, if you are wanting more cam, to do it. Looks lucky that piston didn't damage the cylinder wall beyond honing.
Informative video, I am wondering why not pull the engine
Great video. I know I bought an 06 charge police editio. The valve seats fell out and destroyed the engine. So now I'm looking for a used engine and redoing the heads
Nice video, just wondering why didnt you change the coolant tank because it looks very rusty
As already mentioned, excellent step by step build!
Insanely thorough video for this job! One of the best I've seen on the net. Love how you showed the fix with the engine in the car, which is what most shade tree mechanics would do. Since you had that picker though, did you ever contemplate just pulling the motor out to make life easier?
I had to have my rear main seal replaced under warranty. Apparently they never fail, according to forums. Still don’t know why mine did, and it was sudden and poured oil out with anything more than about 1500 RPMs (oil pressure). One very important thing- The people in the know ALL stress the importance of using the Mopar sealant on the oil pan gasket. Crucial.
Exactly what I did to my charger. This is what I have to do hopefully my pistons can be salvaged it only ran with the dropped seat for maybe 20 seconds
Awesome video, very informative. Thanks for sharing this, going to use your time saving tips when I do my aftermarket head install
Great video! Thanks! I am in the process of doing this job on my 05 Magnum.
Thanks for taking the time to shoot and post this video.
I just bought a 06 300C 5.7 with this issue.
I'm hoping to get it a part to have a better look this weekend (have already had the camera down the plug hole).
Unfortunately Headsonly don't ship to Australia, so I'm going to have to find another supplier if I choose to exchange them.
I wish you the best of luck trying to find parts on the other side of the world.
Watch that upper radiator hose, folks. It's too short! The torque of revving the engine will rip the hose from the radiator. Happens more readily when engine mounts are torn.
hey man good ass job explain this. i wish you made this video 5 years ago my valves dropped on my RT 05 magnum. i have a 07 now and IF that happens again....im coming back to this video for reference.
How is the engine holding ? Im looking into having my mechanic do the same thing valve seat dropped doing minor damage to pistons
I have heard sooo many horror story’s about this issue..iam the original owner of my 04 2500 5.7hemi with 156k.lately I have noticed a lil tapping sound coming from one of the passenger side cylinders..been an excellent truck..did your motor give you any signs before dropping the cylinder head seat..excellent content buddy
I don't think the 04 has the valve seat issue it seems it only effects 05-08 the hemis with the mds
Excellent detailed video. Learned a lot. Thank you.
I hope you learned to pull the fuel pump fuse before cranking to build oil pressure instead of unplugging all the coil packs?
Now that's how ya do a video!
Man u love your dodge magnum. A lot of work..
It just wasnt worth throwing away since we are not phased by work as you can see.
@@cardesinr Yeah, I just freshened up my 5.7 Hemi Magnum RT. Once I got used to the power, comfort ,and utility of the Magnum it's hard to give up. They don't make them anymore, there's really not anything out there that compares. I've got Blastin Bobs exhaust and 22"X9" gray Viper wheels. The car looks and sounds great
I believe these cars will go up in value over time
Great video lots of good information well done sir. By chance do you remember what size the piston bore was for over 200k miles? oversize piston or stock?
Great job i watched it completely and i enjoy to see it
Hate that you had all the damage, just a tip, take off upper rad hose and fans slide out the top.
Did you guys use new head bolts?
Very informative video. Great job.
You should make it a review of the car too, exhaust sound, drive by and all
Hallphamazing305 car is stock this was not bout high performance mods
trips me out when i hear him say bottom lol great video though
What a great and informative video!
Great video very helpful! 👍 Just curious, given the mileage, did you have good compression in the other cylinders? Also what brand of lifters did you use? Seems like OEMs have a history of failing on these engines. Thanks!
Excellent demo 👌
That oil pan looks like a pain!!! Sheeeese
Good first vid of the job on this engines. But, you didn't even show what the failed Valve seats look like from the top.. ?? Not everyone knows or have seen it, that's part of what I came for.
Plus the Cylinder heads looks brand new, are they New or same old ones, But Cleaned?
Awesome video guys! VERY informative & gives me some tips for when i have to do my charger lol.....hopefully not. 👍👍👍
You make this look so easy though I know it takes time and broken knuckles. I have a 2006 Dodge Ram 1500 5.7 Hemi with 177,300 miles. It overheated beginning of December and now I have white smoke coming out of the exhaust. It runs very rough and I'm afraid to use it for fear I would damage more. I want to get it repaired. How much did it cost you to repair the Magnum including parts & labor? Also, how long did it take to repair? I would love to make the repairs myself but don't have all the necessary tools. Wish I could find a mechanic that would be willing to help me repair.
Excelente, actualmente me ha estado llegando trabajo de Hemy's y es algo nuevo, sistema MDS ruidos en lifters cadena árbol de levas etc, el boroscopio increíble, aquí en México caros y difíciles de conseguir, los conocí cuando trabajé en Ford dealer, un saludo, gracias por tus conocimientos.
Feliz de ayudar.
Good video but was wondering how much harder it would have been to pull the engine. seems like you were pretty close to pulling it anyway.
Working on a 5.7 hemi and need the leaf blower to blow out valve seat pieces from intake manifold. Lol. Damn dodge.
Great job I did it all by myself, LOL
Thanks for the vid you should look in to swapping to 09 5.7 heads they fixed this problem on them or even the 6.1 heads both will bolt up
Outstanding video. Thank you!
What was the original symptoms on the engine before you start looking into the cylinder heads?
Thank you! not a lot of videos showing the whole process!
Hope it gets your car back on the road. It's a waste to see that cars less than 15 years old are getting tossed because of this issue...
cardesinr Agreed. This is my first charger. I’ve never realized the 5.7 had these sort of issues. Welp, I’ve started yesterday half way done. Thanks brother!
