How To: 6.7 Cummins Head Gasket Replacement (part 2/2 Install)

[@matthewg1887]

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.

[@darkirondiesel]

Glad I could help buddy!

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!

[@darkirondiesel]

Glad I could help! Thanks for the comment I appreciate it!

[@2004dodge11]

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!

[@flyboy1294]

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!

[@stephenlee5941]

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.

[@kp2529]

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.

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.

[@austinatkins6988]

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.

[@darkirondiesel]

No problem buddy, if it torqued down fine the second time you shouldn’t have any issues

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 !

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. !!

[@nathanbarlown764]

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

These videos are the worst to make haha, so boring and dry. But I appreciate your support!

[@josephchalifoux7930]

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.

[@McNinja243]

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?

[@tommysalami3087]

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.

[@AZTechLabs]

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.

[@knels]

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!

[@Andrew-rb2oc]

[@dextercook657]

Great video appreciate the insight

[@Engine_biulds]

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

[@aaronsherwood2328]

Should there be any fuel coming out of the fuel drain line that's hooks up on the backside of the head?

[@ryandussel8735]

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

[@darkirondiesel]

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

[@skateboardcraze]

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 ?

When doing studs, do you not go back and do a "hot torque" on the studs

[@frankpolowy8651]

Question, What was the reason for changing the head gasket on this truck? Can you see damage to the head gasket ? I feel better when I can confirm the damage that was expected , but have not done a diesel like this before. Thanks for all the detailed info, but not too much detail. Like you said, if we need to know when to use a hammer vs socket we shouldn't be doing this repair.

[@darkirondiesel]

Haha, thanks for the kind words. If I remember correctly the truck was blowing coolant out the reservoir cap (meaning it was pressuring up past the 15psi the cap was rated for). If you look at the head gasket there should be some sort of black material around the cylinders, often times it will be missing part of it which is where the compression from the cylinder is escaping and going into the coolant system. I have a 6.4 powerstroke in the shop right now that I’m doing head gaskets on. When I get the off I’ll make a video showing what a blown head gasket looks like!

[@frankpolowy8651]

My cummins is in a 2011 F650. The head bolts I removed are all the same length. Why would that be?
