- Had a couple guys ask about the 5.9 blocks to a 6.7 block. There might be a few things I forget but If I think of anything I will do a update video.

Great video! Thanks for sharing, this is exactly what I was looking for! Subscribed and looking forward to learning more from you. 👍
Never knew how close the 5.9 and 6.7 engines were. Thanks for the info
Thanks for watching
Great info, thanks Rob!
When I blew a head gasket in my 6.7 I wondered how this could happen since I had never had a 5.9 head gasket issue. When I pulled the head and saw those coolant passages I knew exactly why. That was 2012. I haven't bought another 6.7 since.
oh man, now I have to build a 6.1 cummins, I feel challenged!
great explanation
Great stuff👍👍
Thanks
@@CUTTERUPROB any idea why the 6.7 has steam port Holes?... Cause of siamese cylinders??... Idk ..just curious
I will show it in the cut way video when I do it
Seriously this was awesome can you do another one of these videos with the 4 cylinder B series? 3.9(5.9), 4.5(6.7) and specifically additional proprietary info for the 3.3 block?
If I have some come in I will
Thanks that will be awesome
So could I bolt the gear housing and stuff to a 5.9 p pump from the 6.7 I’m asking because I have a 6.7 the locked up from no oil and I have a good 12v out of a 96 I want to swap in and get the sensors to bolt up for transmission to work?
It can bolt up yes. But you want to figure the trans part out first
Hey Rob, so the larger 8 plate 6.7L cooler will fit in the 5.9L & not have any adverse effects? Also what CR engine years can you add a 2nd piston squirter too #6 & what size ect? You once told me I could shim the oil bypass spring 50k to increase the psi to safely run compounds & a bypass or centrafuge. Would your also drill & tap the cooler for its own port or T off one of the turbos ? I like the idea of a separate port, where is the best place to ads one? Thanks ! Dusty
Very good info. My oil pump kind of “walks” a bit more than I’d like in my 12 valve I wonder if they sold me a cr pump.
the 12v is the small pump. so you won't have a cr pump on a 12v without machine work but i have seen some 12v pumps looser then others
Also commrail pumps are straight cut, older 5.9s helical
ok 2 questions #1 will that common rail girdle fit on a 12 valve storm block? #2 will a 12 valve head bolt on to a 6.7 block? just curious I've never tried to mix parts from common rail/ 6.7 to 5.9/12 valve stuff.
Girdle no and 12v head yes. But have to do couple things. My race truck is a 6.7 block 12v head
Nice!
So if I want to build an motor for my 2016 6.7 are all the 6.7 blocks the same year wise or are they different from 7.5-13-14-18 ?
block is the same yes but there is some other differences
I would like your opinion. I have a 2017 6.7 in my RAM 5500 and would like to add a coolant block drain for maintenance purposes. Where would you place it?
Thanks in advance
Luis
i will do up a short video for ya
You forgot to mention the 12 valve international cast block!
I will get into that when i do more block video's
why would you build a 6.1 when a 6.7 is available? I noticed your video where you sleeved the block back to 5.9. was that for running a 12 valve head? my question I guess is why lose cubic inches when the stroke is the same? can't find any info on torque differences with bigger cubes and the same stroke. I am building one right now but wonder if it is a waste of money.
alot has to do with what you want to do with it, i sleeve the 6.7 block to a std 5.9 sore for strength, the ad dis of the 6.1 does make a different in spool and torque, but really comes down to what you want,
What about the motor mount areas I know the old 12 valve is 4 bolt what about 98 and 1/2 to 2002 24-valve versus the Gen 3 the 5.9 and the 6.7 Cummins are they all 6 bolt and in the same area?
the mounts are different but the block is the same
@@CUTTERUPROB so you could interchange the mount bracket between the blocks? well better put, Is the bolt holes for the mounts the same pattern across all the blocks?
Do video on the 5.9 6.7 piston pin hight if you don't mind so we can see the difference thank very good video 👍👍👍👍
Yep good idea 👍
Coming up
Love 12v
I might buy a 1998 12 valve. But I read around in 1998 had some 53 casting. Can you do a video on the best and worst casting in Cummins blocks. And does the 1998 12 valve use 53 blocks. Thanks
I can do a video on that no problem
To the best of my knowledge, The 53 block was only used on the 98 24v.
Can u run a complete 6.7 short block and runs 5.9 head with 03-04 injectors ?? If so what head gasket and head bolts do u run the ones for the 6.7?
You can just run 5.9 injectors in the 6.7 head.
@@CUTTERUPROB What about the spray pattern
5.9 block full coolant flow around bores, 6.7 siamese bore casting. That's why the 6.7 blocks are stronger
I am going to explain it in a later videos
I installed a 6.7 on my 05 ram i have it running with 5.9 fuel system, and injectors from original engine only issue is it smokes at 1,300-1,500 rpm what adjustments can I make?
As far as I know only way have the right nozzles for the bowl
I want to buy a 6.7 for my 05 ram Cummins. The engine I saw has fire damage. Burnt. Do I’ve to do the head gasket on it if buy?
you would want to completely tare it down and do bearing , rings and gaskets at a min
Do you know the differences between the 07-12 6.7 block vs the 13-18 block?
basically nothing
You should do a video on heads?
Can do
How big of a bore can you go to in a 5.9 block with or without a sleeve?
.040 over is the biggest piston you can buy for them
So can i use a comon rail 5.9 block with a vp44 head to replaces a cracked 53 block?
You can but have to modify the block to take the timing case
Are the lower water inlets/ ac brackets the same between the two?
The brackets it’s self no.
So......if my 5.9 CR ever gives up, I can swap it with a 6.7 short block and have no issues?
you can with the right pistons
I would bet a nickel someone has a kit for that. Still, I’m a little concerned about the coolant passages. The steam holes would be dysfunctional.
What does "common rail" mean? And what year or model did these begin? Thanks!
It’s the style of injections system. I will do a video on that. In a Cummins in a dodge truck it started in 2003
@@CUTTERUPROB Thank you!
Good video in your opinion which one is more reliable?easier to maintain?
in the end i would say there close to the same for both but if i was picking it would be a 6.7
What factory girdle is best ? And what size bolt for an early 6.7 bought and engine and they are missing bolts and girdle. And the early girdle is discontinued and so are the bolts please help thanks i. Advice
I like the heavy factory one myself.
@@CUTTERUPROB that what i was thinking too i just didn't know if having the holes and drop down in the new one would be better for keeping oil on the crank. Do u know what size bolts they are to hold them on because those where missing and i cant find a size and dont what to rip the old engine apart
@@acrophobiar1 there m10 25mm long
@@CUTTERUPROB thank u very much now i dont have to take that one apart!!!!!!!!
Are 6.7 and 5.9 the same length and weight? Thanks for the video?
Basically yes
Are the oil pans the same bolt pattern?
Common rail to common rail yes
So I can by a 6.7 short block when my 5.9 block takes a dump?
Yes. But depends on the engine ( year of engine you have ) if it will have chance parts
I was think about building a 6.7 block with a 5.9 head for my 01Dodge is that possible and do you do that. Im in the state of Washington. Thank you
Witch this series. It will question your questions
First video of the 6.7 Ppump engine build series
ua-cam.com/video/Y2kjX4sSewI/v-deo.html
6.7 sits further up in the truck by about 1-2” compared to when I had the 5.9 in I had to trim off that much on the turbo tubes and floor for the g56 or maybe it’s me idnk
Should have too. The mounts are in the same spot ( well I pretty sure that are ) I have put them in a few trucks no issues. That said if you used a 6.7 engine plate it’s deep by 1/8 of a inch of so
The 6.7 oil cooler has 1 more row than the 5.9CR oil cooler
Ben a while seen I counted them. They very well could be
Do you know how many thousandths lift on my p-pump is stock for 14 degrees , I believe my timing arm is bent in my pump
depends on what pump you have
@@CUTTERUPROB I have a 175 hp pump
Can 12 valve 5.9 be bored and stroked to a 6.4 or 6.7 ?
not but you can doa 6.1 if you use a 6.7 crank in a a 12v
so there is no way to tell the difference between a 5.9 or 6.7 block while its intalled in a truck?
block there is a couple things. i will do a video
So you can p pump the 6.7 block, manual fuel pump?
You can. But it’s not a bolt on thing with out a custom timing case
@@CUTTERUPROB I have a 01 24v I want to run my vp44 and timing cover what modifications have you ran into
I have thought about buying a Dodge cummins for a long time, Is 5.9L more fuel efficient than 6.7 l on a 2007?
I think the 6.7 in better engine myself. Mile is about the same
@@CUTTERUPROBwhat’s longer lasting
is that a p pump on that 6.7 block?
Most likely it’s my preferences engine
one reason the 6.7 is stronger, the cylinders are joined or "Siamesed"
sure are, i will do a video on it but i need a couple block to cut up first
Some people told me they bolted 12v head directly on the 6.7 block
Yes they bolt on
@@CUTTERUPROB no modification or drilling needed? Besides injectors and lines of course
@@CUTTERUPROB what about the steam hole? The tiny hole between cylinders
Looks like my garage at Home LOL
Mine too
@@CUTTERUPROB my engines stay with me unless i get paid what their worth let their truck sit
i have 50 cummins engine so i know what you mean
@@CUTTERUPROB nothing cheap on a diesel
98 was last 12v, 98.5 24v Not that it really matters tho.
depends on if you ordered it o have a 1998 4 door 12v built is 11 month 1998 lol but your right.
@@CUTTERUPROB I have a 98, 4 door, 2wd, 5 speed 12v that was originally a 53 block. Some weird reason that block was cracked lol
well that's a down side of some of them, better then what happened to mine , it got hit by and dump truck lol
@@CUTTERUPROB Ah man that sucks shit. Luckily the thief that tried to steal mine was so incompetent that they only managed to mess up my door and door handle and nothing else. Still disappointing none the less
@@dustindd789. ya that does suck.
♥️C♥️U♥️M🤘M♥️I♥️N♥️S… 😘

Im getting parts together for a swap. What 6.7 would i need to put a 12v head on and it work? Is it a reliable combo for a tow vehicle?
It’s not that easy. If you want to run a 12v head with it as a 6.7 the pistons design doesn’t work with small injectors. I will do a video of what I mean shortly
@@CUTTERUPROB makes sense! Im piecing stuff together and thought if it's worth while i can focus on that instead of just redoing 5.9 12v engine but a video would be greatly appreciated!
