I already thanked you but I’d like to again, I just finished replacing my HG and replaced my bolts for studs. Without your videos this would have taken longer to find all the information than to actually do the job. Thanks so much man. Really appreciate including the torque specs.
Glad I could help buddy!
Was about to say the same thing!

Great video, just got my 2013 cummins running again after a month down since the grid heater bolt melted off and went through my engine. Rebuilt head, 6 new pistons, injectors rebuilt, rebuilt turbo and grid heater delete with aftermarket heater on intake tube. Anyone with a 2013-2020 cummins make sure you check where your power cable connects to the grid heater, if it's loose do not drive it until you replace the fridge heater. Ram service bulletin calls it the wiggle test!
After watching the removal video, I have my head back from the machine shop. It has been pressure checked and resurfaced. I watched your video and wrote down all of the torque specs. Replaced my head gasket with an original Cummins head gasket as my truck has 193k miles on it with and the head gasket looked fine upon removal. Lowered the head into the engine compartment and installed a new set of ARP head studs. Followed your steps to the T and “Shazam” she fired right up! I would have never tackled this job without your videos. Thanks again!
Glad I could help! Thanks for the comment I appreciate it!
Excellent video. I am about to replace my HG on my 2007.5 6.7L due to failure. My truck has over 300K miles on it so I believe I have gotten pretty good life out of the original. I will definitely watch both of the video’s again before I begin and probably a third time before install. I would like to make one comment/suggestion on your procedure. I am retired from the military and worked on helicopters. I seem to recall a technical bulletin that came out against using petroleum jelly. We used to use it when replacing seals to keep them in place when working on the fuel cells. Petroleum jelly does not dissolve in jet fuel which is a high grade kerosene, much like diesel. Try it out….place a blob of it in some diesel, it will just sink to the bottom and sit there. It also calcifies in high heat which will reduce the life of the seal. Use wheel bearing grease instead. I hope that helps. Thanks again for a well done video.
I just completed an in-frame rebuild on my '13 6.7. This video was awesome for reassembling the head, injectors, and valve train. Wanted to say thank you for the in-depth info. Subbed!
Thank you so much! I’ve been building hot rods and race cars my whole life, but this was my first HG job on a diesel. I had already purchased the ARP studs and knew most of what the job would consist of, but diesel fuel injectors are new to me so thank you so much for sharing your knowledge.
Thank you for the effort made in this video!! It was super useful. First time I've ever done a job this big on my own and your video made it really easy to find the answers. Torque specs and all! Very nice. Well done. Amd Thank you for putting this out there!
Nice video and thank you for making the decision to skip all the little beginner details but still providing some very helpful tips. You are absolutely right in thinking that someone who tackles this job should already have some experience.
Excellent video man, fixing to have to do a head gasket and studs on my 07 6.7, not alot of really good videos that explains everything like u did thank you so much 👍
Probably the best video of any vehicle repair ever! Super clear and you state the torque specs! You are amazing! I think my head gasket is going. Gonna bypass the egr cooler then if its still losing water it will be the head gasket. And your video is gonna help so much!! Thank you
Thanks buddy! Glad I could help, that’s why I make the videos!
Just found this vid and watched for pure entertainment and to see if there's an easier way to do this stuff and you are the most informative RUclipsr I've seen
Thanks buddy! I appreciate the comment, really fires me up to keep at it!
@@darkirondiesel yeah man keep it up! I'm a mechanic and I know how to do this crap but I find the hardest way 🤣
Thank you for the awesome videos on this. You did a good job explaining all the important stuff.
just replaced my 08 head gasket watching this video, can't thank you enough saved me a ton of money!
Great video! Thanks for gong in depth on this! Almost comfortable to do mine!
Great vid , super helpful for the weekend wrencher. satisfying to finally hear that baby fire !
Thank you!
Long time listener first time caller,
Watching your video of the head gasket job gave me the confidence to do it our selves vs having a shop do it. We are half way, heads at the machine shop. Most of the parts I ordered are here and we should be firing it back up with all the new goodies installed this Saturday.
Thanks for posting !
Love comments like this!
Thank you. I have to do this job so I appreciate the view of the work and tips and specs.
This video was excellent. much appreciated, thank you.
Great job on your videos ! I had to subscribe ! Very detailed ! Thanks for spending your time filming ! Please make lots more !
Thanks for the sub buddy!!
Great job sir on both videos!!! Thanks for taking the extra time on creating the 2 videos!!! You boosted my confidence level! I will be installing the ARP 625's and contemplating if I want to put in a new HG too...
How many miles on the truck?
@@darkirondiesel 100k
great video! i keep coming back to this video as im doing mine in my driveway
Great video man. Thanks for putting in the work.
Thank you for both videos man, I just finally got the head on but you have made everything so much easier. Great video and great instructions man, I want to give you a hug haha. Things wouldn't have went so smooth if it wasn't for you!
When I installed my Rocker Pedestal, one old bolt sheered when torqueing. Luckily, everything is so lubed up and there was enough bolt exposed that I was able to remove it easily. I installed the ARP 247-7201ROCKER PEDESTAL STUD KIT to replace the OEM bolts. It was a pain in the ass as I had to temporarily install a grade 8 bolt until the kit came in. Then I took apart everything again to complete the install.
About to tackle my 13’ with 350k your videos are definitely a life saver. So much info. Much appreciated
Thank you! Good luck!
How did it go? I was thinking on doing a full rebuild on a 6.7 with 350k miles that blew the HG. Maybe i can just replace Hg.
You videos are life savers man!! Keep it up!
Awesome video. I just bought a 09 Cummins and anticipate doing a head gasket at some point in the future and will definitely refer pack to this video. Just watched it for entertainment this time. Thanks for making it. Great job.
Hey, you’re welcome!
I just finished changing my head gasket followed your video exactly and came out perfect thanks so much bro!
Thank you for taking the time to post this. 👍
Well, I finally got everything in today, just need to get the valve lash set and button it up tomorrow..
I screwed up and over torqued #6 injector hold down but loosened it back up and set it properly like you described. Hopefully it’ll be ok, I found in a forum some guy had a hold down bolt break on him while torquing it down eww..
Thanks man. I referenced this video often while tearing down and replacing. Tomorrow will be the glorious moment of truth.
No problem buddy, if it torqued down fine the second time you shouldn’t have any issues
@@darkirondiesel she’s good to go man. Thank you for your in depth video’s, they aren’t easy to make by any means. She fired up after bleeding the injection lines. Much appreciate from Nevada brother. Keep on keep’n on!
Great video! Your instructions were perfect
Amazing video.
Thank you for all the great information
Thanks!
I have no need to do this, have no desire to do this, but jesus christ you just got my sub. Watched the EGR/Flo-Pro install. Doing that this weekend for the second time, but I wanted to see how it was done on a newer truck. 07.5 to 2016 is a big change lol
Bro that's was an a great explanation God bless you
Dark iron ..
I haven’t commented on a video quite possibly ever. Thank you very much for this video, unfortunately you should be getting paid more than most of these videos that mean nothing (hear this whistle diesel).
Only some people know how to explain a process, you sir are one of them. If you ever find yourself in Alaska, let me know if you need anything.
You helped me immensely on my head gasket replacement.
I can only image the people you help, and I’m guessing you only hear from a small portion of them.
I am extremely thankful for the time you put into the video. !!
Thank you for the comment it means a lot to me! I’m glad I could help
I agree with everyone else, thank you for the effort. I’ve tried making videos and just don’t have the patience! Anyway, I know I’ll be doing a HG sooner or later on the Beast outside, thanks for all the pointers!!!
These videos are the worst to make haha, so boring and dry. But I appreciate your support!
awesome video Bro.
Well done!
thank you so much! you have saved people thousands.
Great video, very helpful
Just picked up a 14 3500 w/aisin c&c 4x4 truck for 6000, head gasket went out. Really looking forward to tearing into it 17yrs old I'll let you know how it goes. Should be fairly smooth especially with a video like this seriously I greatly appreciate the information, got yourself a sub
Awesome, How d it go
thank you for your time. this was a very good and detailed video. I have subcribed.🥇🏆
Thanks a bunch for the video. Very good
Thank you so much for this video
Awesome video and thanks for sharing
Thanks a million for this video without it this job would be a major pain.
One thing I’d add if you mark the back of the harmonic balancer with a paint pen it makes life much easier and imo it gives you a more precise tdc. I marked one of the teeth on the crank shaft sensor ring. There’s a mark on the bottom of the engine to line it up
Thanks for this absolutely grateful
Great video appreciate the insight
Tank you for taking your time and explain it out perty good 👍I feel better and comfortable to do my 6.7 head gasket and studs and turbo, but I'ma put a whole new rase Head on my truck 😁🤙 gracias por Todo
Great Job...Thanks for sharing...
Thanks for that helpful video
Thank you buddy for your info
Awesome Video Thank You !!!!!!
Well done!!!!!!!
AWESOME !
Great video .
We are about to undertake this project and are stoked to have this great tutorial to help. Thank you! You seem professional and pretty chill. Mahalo from Maui! Where are you?
I about to tackle this same job on my Uncle's truck and also an egr delete. I greatly appreciate the amount of effort and time you've put into both of these videos.
With that said, I do have to ask what was the initial cause that had you do this job?
Very good video.
Good job thanks for sharing
Thanks!
Excellent
Great videos sir. Thanks for the info. The studs (and or bolts) are springy and with bolts they are already bottomed out, no way to add more torque to them without taking them out and adding washers which is not advised since they are already stretched to load.
good job brother
Thank you for putting this out to the world. I am literally watching your how to videos over and over until I understand everything. Would you recommend going to a junkyard and practicing taking apart things or just buy an old beater to practice?
I just started out by working on my pos and all my friends pos cars I’m no expert but I can fix just about anything and much easier these days with RUclips
Very good work. Great video. Unfortunately I am about to be doing the same job. Just got the truck less than 2wks ago, guy told me it was a great truck, "wouldn't hesitate to drive it to florida tomorrow ". Mmmmhmmmm they all say that 1 line of bs. Damn water pump puked on me on the way home from buyin it, got sorta hot, 240 for literally a few seconds before i shut it down. Now im noticing too much pressure in the coolant system and the overflow is taking on coolant beyond the max line. Had i watched this video first and noticed that you can see if the head has been studded or not before hand, i would be sittin much more happy. Dont buy a truck that has a tuner on it and has been studded. Especially from someone you dont know to be a reputable human. Thanks for a great video. Wish me and my knuckle skin luck.
Damn good video man
Thanks!
Dropping in a fe studs makes the head alignment super easy
Ya I guess, once you have the cylinder head hovering over the block then I could see it being easy for sure!
You are my hero! I have everything disassembled and I'm currently waiting to get my head back from the machine shop.
I see in the video you're using a Fel-Pro head gasket (I copied you and got the same one) Just curious though, How has that gasket worked for you? And is there any particular reason you chose that gasket over other gaskets, namely an OEM Cummins gasket?
Thanks for all of the content you're providing! Keep it up man!
Solid Videos! Out of curiosity what was the exact reason for the head gasket change? Completely blown or did it have gurgling in the coolant reservoir like mine does when you shut it off?
The videos were well done, made it very easy to replace the HG, I'm all done and tried starting the truck - no go. I've gone over everything from valve adjustment timing, connectors, put back the old injector harness as the truck drove in the garage. Fuel at the injector tube, charged Batts. Any suggestions Sir?
Thank you so much for this series! Very helpful for a first timer. Quick question, where did you order your ARP studs and gasket kit from?
How do know if he is blown?
How do you know if HG is blown?
@@reginaldpugh4691 My radiator was getting pressurized and blowing coolant out of my overflow tank.
Can you make a list of all the gaskets and Orings and little parts you would need to tackle this project... Have to do mine but don't want to pay a shop! Thanks great videos will follow everything you did.
I just get this head gasket set MAHLE HS54774-1
i was curious what grit the pad u were using on the di grinder was.
Rocking video. I am a shade tree and tackling my 16...kill me...
When adding head studs, what are your thoughts on hot retorqing them?
What is the typical time involved for this project? Good job on the video!
Would you recommend the Fel-Pro kit over the Mahle?
When doing studs, do you not go back and do a "hot torque" on the studs
what brand headgasket do you use? is there a gasket kit you recomend that comes with injector seals??
What are the red and blue tools you used to adjust the valve rockers ??
are there advantages to the felpro gasket over the mopar gasket ?
I have one question about a 2013 6.7 cummins. I found out the hard way that the grid heater stud got burned off and fell into the in take. What are my options? Back in the 80s i was a ase cert but never work on a diesel engine this is my first cummins I bought it new. I jest need to know what I need to do to find it ?
Can you add a parts list. Of all the gaskets and such you needed to get the job done
Awesome video about to tackle my 08 6.7 how long did it take to pull and drop the head start to finish not including machine shop turn around time?
It usually takes me about a half day to remove it and then a full day to put it back together if it goes well. So about 12 hours I guess, but I’ve done lots of them!
Dark Iron Diesel awesome thanks so I can expect twice as long if everything goes right lol 😂 definitely watching this during the whole process!
Haha ya definitely took me a lot longer my first time
What kind of hours do you put in doing a gasket this way?
Where did you get those stepped feeler gauges? I can’t find any that are angled.
Hey bro I just replaced my head gasket but when the truck started there was this nocking and a bunch of black smoke any ideas what it could be
Should there be any fuel coming out of the fuel drain line that's hooks up on the backside of the head?
not sure if anyone is going too see this i just got done replacing my gasket and head watched both of your videos now i can't get it too start pulled a fuel line and it's pushing fuel out but still will not start cranks just fine gonna try and get ahold of a scanner tomorrow and make sure i'm getting enough fuel pressure too make the injectors fire any tips or pointers too look at?
Awesome videos. Thank you. How many hours would you say this job takes. I was quoted 15hrs witch made me think im going to give it a try. Ive done everything eles on the 2011 over its life. Why not the HG haha thanks again
Haha 15 hours is pretty reasonable.
so mine failed and unfortunately was driven you a bit once i got the head off the stench was gnarley im pretty sure some oil got in the passage you said dont let oil go there is there any extra step i need to do if im pretty positive oil got in there?
Video is great but I frown apon people that use a diegrinder on a gasket surface so important, especially on a surface that already has trouble sealing, Just pure laziness.. its one thing to use on a water pump install or intake if your careful but, on a head gasket surface??? It risky business.
And to add further you won't warranty your work without a performance related upgrade.
You should realize the only thing keeping that gasket in check (in regards to coolant and oil) is the film coating on the gasket face and between each layer of the MLS gasket.(most cheap gaskets are a hard coating that are little help in sealing but do ok) just a better gasket is one that has a slightly rubber like thin coating... these are the best at sealing imperfections like what you caused. Most people don't have 500$ for head bolts so sticking with a proper "more professional" habits will get you further.
Great content good video. Just glad that truck isn't mine
You should not try to bleed high pressure common rail system fuel lines, that could end in serious injury or desth these systems see as high as 28k psi of fuel, I know startup is not that high but still very dangerous, it is a self bleeding system, Also shouldn’t be using air powered or any rotary tools they can remove too much material and create high and low spots other wise great video
Personally I’d rather bleed the fuel system like this instead of cranking the engine for 5 minutes until it self bleeds. It shouldn’t build rail pressure with one of the lines loose, and even if it does just don’t go near it when you’re cranking.
As for cleaning the engine block I know technically you aren’t supposed to use an air tool but I clearly say in the video to use a fine grit disk instead of a rough one and to do it gently so there aren’t any sparks because you don’t want to take material off.
Chances are if someone is watching this video to do it themselves at home they probably aren’t going to be doing it by the book anyways haha
Great info great video. I have a question.. this is my first time doing this. I did NOT take the head off or any of the stuff that needs to come off. A "mechanic" did. Anyways I'm about to put everything back up. But..... injectors and injector tube and so are the small fuel lines were all just thrown in a box. IS THERE A WAY TO FIGURE WHICH TUBE GOES TO WHICH INJECTOR AND SO THE SMALL FUEL LINES? thank you and once again great video I have watch it twice so far lol.
Haha thanks buddy. You’re just going to have to put them in random holes. If he didn’t mark them when he took them out then there’s no way to tell where they came from. But you should take pictures of the trim codes on the injector and record down which cylinders they went into then have a shop program your trim codes in. Chances are the truck will run fine even if you don’t program the trim codes in, but if you put the truck back together and it runs a bit rough then you will have to program the trim codes
@@darkirondiesel thank you so much .. another headache sound like lol but can't wait to hear it crank up and run once again. I APPRECIATE YOUR REPLY AND THE VIDEOS
No problem buddy! Like I said just throw it all together and fire it up and see how she runs. If she runs rough then get the trim codes programmed, but it will probably run fine. But take pictures of the trim codes first and remember which cylinder they go in. Trim codes should be 6 digits long on the side of the injector towards the top.
👍🏾👍🏾👍🏾gracias!!!!!!!!!!!!!!!! I sure will take pics and will write it down
Is the removal of injectors and tubes necessary if you're trying to just get your truck on the road again? Can a guy leave those in place, replace the head gasket, set her down and clamp away?
Well you should never replace a headgasket without sending the cylinder head to a machine shop for pressure test and resurface. But I guess in theory you could do what you are suggesting, although I definitely wouldn’t recommend it. Might as well do the job right the first time in my opinion.
How do you know what thickness of head gasket to put on. I didn't see this addressed in the video.
I was on a website reading about a new head gasket install. For its installation prosses, it talked about doing 80 ft lbs head bolt torque, run engine until warm (Idle only) and re torque 125 ft lbs, also setting the valves twice! is this something you can avoid ?
Ya I don’t do that personally, I don’t know any mechanics that do that.
Hi I do everything like did you said but my truck don’t start make a noise nock in looks like no diesel scan the truck and have a code cam sensor buy a new one but do the same I do everything did I can but does not start if the tdc is wrong can do that trouble
I have witnessed my freightliner m2 has oil in my reservoir. What could be the issue? Where are you located?
How much did the milling take off of the head? Did you go back with a standard head gasket or thicker? I can’t seem to find any info on this part of the process.
Have you ever had a issue with the exhaust manifold not lining up? 6.7 cummins. I've been fighting it all day literally. Do they shrink?
Did you retorque head studs after a heat cycle? Arp told me its not required but everyone says to do it thanks!
No it’s not required unless your planning on building a race truck
