Nice and he is fortunate to get to learn about his truck . No better way to appreciate what you have than to be responsible for building it.

So much great content all in one video. Love it. Thanks for keeping us in good content.

[@horsetorquesdiesel]

Glad you enjoy it!

[@Bradzuzu]

Good stuff thanks for making the video !! I'm going to be going through my donor engine very soon an will set the engine up on my stand that way looks way safer ..

[@bert5003]

love this type of content and format. definitely learned a thing or two i may use in my own junk.

I’m getting my old 12 valve for mine first GEN Rebuild a DNJ machine in Cambridge Ohio. Those guys seem like they really know what they’re doing down there all right this is six in a row.Jim from Kenner, Dale, Pennsylvania

[@cumminsnchevy]

Lookin good Josh! Glad Donald decided to put some studs on. My favorite method for remembering firing order on inline diesel 6’s is 15 is too young 36 is too old but 24 is just right👌🏻🤣

[@horsetorquesdiesel]

Mine too but kept the video PG 😂

“Promise I can. I got two trophies.” Put that on a shirt. Great video.

“Who am I kidding” 😂😂

[@brianpuff9021]

I checked out Manton new roller rockers,5 gran!!!thats crazy!!!!!

[@witcher71]

Everybody is off their rocker with prices.

[@hankclingingsmith8707]

The trick is to torque each one as you replace them. The order of replacement does not matter

[@Altekameraden79]

My 380,000 mile 12v has suddenly started blowing by and hazing regardless of rpm. I don't have a shop to do the work myself inside as I am in Wyoming. So I'm starting to price long block builds. Both with and without install.

[@baconcreek609]

If your being cheap on the tappet cover, super glue it to the cover and also to the block.

[@c-man6376]

What rtv do you use or recommend? Looks like the "right stuff" based on the can but is it the black or the gray?

[@baconcreek609]

26° timing rattles the old 12v pretty good.

[@_astralxinfluenced_2799]

Do all Cummins have the wear ring from the rear main, or just the 12v's?

[@JRasS14]

Just did this in the truck. Not a good time Definitely loctite guys, crazy how many bolts felt loose. My kdp was still sitting tight

[@fernandolouismiramontes2520]

Does the 5.9 need an ecu at this power level to run or is it possible to be all mechanical injection still?

[@matthewgarcia4081]

Hey justin I’m 24 just tryna learn what I can, want to do similar upgrade’s to my 12v Cummins,never done motor work before in that depth but I’m eager to learn, would you recommend a specific service manual to read and follow as a guideline? (Any tips or advice would help)

[@horsetorquesdiesel]

Honestly dig up the old comp d and Cummins forum threads! A lot of good info

[@baconcreek609]

Daguum, you got me wanting to build another engine....

[@horsetorquesdiesel]

Do it

[@TheProchargedmopar]

👍💪

[@fabianpendl3557]

Fun fact about xotic headstuds. They’re actually Canadian made not Chinese lol

[@Scott_Buchanan]

What’s the hp/tq limit on a ve pump 12 valve?

[@melvinwilley3087]

I’ve used the xotic studs on 6.0 power stroke’s with great results

[@chandlerlofton6536]

Does the engine stand bolt right up on the side like that? I had mine mounted from the back before I sent it to the machine shop. It was a little sketchy.

[@horsetorquesdiesel]

It uses 3 bolts and it bolts to the holes in the block that use the engine mounts

[@chandlerlofton6536]

@@horsetorquesdiesel sweet! I’m going to do it that way when the block comes back. I think I have the exact same stand you are using.

[@jamesebanks5543]

New valve seals ?

[@horsetorquesdiesel]

Nope these looked perfect! But definitely check them!

[@3am-421]

Does he have a insta?
