Since this is an old video I don’t know if you’ll get this comment or not but anyhow where are you been dude haven’t Heard from you in a long time you did pretty good in the UC see deal and anyway it’s a six and a row jim From Kennerdell PA
First finely man it's clean inside shows how strong Cummins is and how good your tunes are. You the man
I'd reseal it and keep for backup
Cummins power is real power !
Those engines are very strong 💪
Nice video 👍
A well maintained engine, so clean internally!
Not even thru the entire video and I’m wondering how many people are going to blow their engines now thinking they can run 1000hp safety lol
Hmm... I should have had a disclaimer!
Turba Tom fuck it
Turba Tom Running 1k HP on a stock 150k engine and it looks like a new motor. You must’ve done something right with your tuning to achieve your motors visually immaculate condition on the top end. Even the bottom end looked great, but I’d still change the bearings IMO. Great job.
@@Backyardmech1 I don't think the engine itself is 150k. Unless you're adding the mods done to it to the price. The non High output versions of these are only 9k
I was being facetious. Clearly with engines like this and the kinds of power output it’s clear. Even 9k for a motor alone is outrageous for a start. Big power means big dollars on any platform.
It's normal discoloration from the inductive heat treating process on the crankshaft Tom. The theory behind it is instead of hardening the entire shaft, they only harden the journals so the shaft is less brittle, and less likely to crack.
That engine looks great. I'm gonna find me one of those and put it in my k5 blazer. Thanks for the info and keep up the great work. Aloha from Hawaii
What I like about watching these videos is I also learn from the comments people write in
What is 6.7 in Cummins engine
Owen Wilson would be proud every time he heard you say, "Wow."
I drop the freeze Plugs out of my Race 351w . Use a little anti sz pop them back in 8 years ago still runs great . doing upgrades now.
When checking your cross hatching you wanna check the major and minor thrust sides. Your major thrust side which will be the left side of the cylinder as viewed from the front of engine will have the most wear. Your minor thrust side is the right side. The blueing on the crankshaft is normal and is from the build process. The journals are superheated and then quenched so add hardening.
The rod bearing wear is normal. If there was deep divots there might be an issue but it looks fine from the video. The journals are heat treated so the blue coloration is normal. As far as the cylinder that only had 390 compression check your gap tolerance to see if that piston is coming up short of top dead center. If it come up short the rod could be slightly bent causing compression loss. But considering the cylinder walls looked fine it’s probably just normal wear and tear on the rings. Love the content man, keep up the good work!
RC_Fab Shop Im really betting it's a slightly bent rod. That was my first assumption when Cyl. 5 came up a little short.
Ryan Brown same here man. But usually it would put the piston angle off near top dead center and leave scoring on the cylinder walls.
Blueing is part of manufacturing process of the crank. They heat treat the journals and leave the rest of the crank soft for wear resistance and toughness.
How much stronger would you say the 6.7 is compared to the 5.9? I have 2 5.9's and have dragged duramax trucks and power strokes. I would like to get an even more powerful truck and was just wondering if the 6.7 is worth the hype
Well, the good news is that you now have a spare race truck motor. I would check your rods and replace the consumables and put it back together, hen you can just go ahead and ship it to me 😄
Are you thoroughly impressed tho? Just kidding man 🤣 great vid, loving my 6.7... only deleted and tuned tho no goodies like yours. I'll be watching your upcoming vids 👍
Hahahaha!!! Thats good stuff!
How much
he passed away back July
Just a thought on your compression numbers, after seeing all the oil in the cylinders it's possible the oil helped seal up the rings. The cylinders do look good for what they have been through.
Bro grease them screeching wheels my mom almost died hesring the sqeal 😆😆☠ awesome video!
I wonder if your impressed?
can't believe how good that look's tom just goes to show you can't beat a cummins
Nice job. Just figured you would strip this baby down. At least when you sell it they can see everything rite up front . Id definitely sell the motor and put it towards the new build. Thanks for sharing.
Counter weights are heat treated from factory
On the cylinder that had lower compression, check at top dead center and see if that piston is as far up as the others at TDC. Curious if it lost a bit due to rod deformation that people talj about with these 6.7's.
It’s your light that makes it look blue... LED lights do that to somethings, it’s weird but hit it with a low power light (cellphone) and it’ll look different!
The bluing is normal. It’s from the heat treating process
Are you using Makita?
What weight and brand and/or synthetic, of oil did you run for the duration of you owning the truck?
Hopefully Schaeffer oil 🏁🏁
Shaeffers for the most part, but rotella t6 in a pinch
Turba Tom so I guess then t6 is a great oil on my bone stock 6.7 if it’s your backup oil with 1,000 ponies
Don't forget you promised me the fleece coolant bypass 👍🏻
We could make that happen
Turba Tom oh damn. Wow. Um ok. Great. I take it you got other plans for cooling the next motor then. 👍🏻
Yeah, things are changing alot. Email me at turbatom85@gmail.com
Pretty sure #5 has a intake valve mark on the piston. Idk what cylinder you had low compression on but if it was 5 probably bent valve.
She eat fuel like a v6 toyota... that alot. Or maybe my injector needs replacing. 368000km
I’d like to know how many hot runs this old girl had I’m starting to not to worry so much on mine I’ve hit 1500 a time or two pulling some hills loaded?
Engine looks brand new!
That girdle isn’t factory is it? Who made that?
Looks like 3965764
Factory
My big cam Cummins makes this look like a toy!
Damn just pick up the truck tom lol
got hot
Re assemble the engine and put it in the 2nd gen😂
Why do people build engines without a stand. Been building engines gas and Diesel for 35 years. I have 7 stands.
Where did you get everything for the oil pressure gauge set up does it come as a kit?
It's just a gauge and an reducing bushing. The port is already there
Turba Tom thank you keep up the hard work.
Do you mean 1000 torque? They don't come from factory with a shitload of horsepower for a reason cause they go in work trucks and are meant and needed to last
On the blue color on the crank, if all them have. They’re heat treated. At least on my 5.9 the 2 cranks I had were that way. No worries on that engine! Looks very good! I’d love to p pump that motor, now that PDD made an adapter plate for it!
You make some very good common sense points. But if you're going to handle these engines get the right tools to do it properly! Don't lift it by two bolts! Get the proper equipment to do the job!!!
Changed oil in mine every 5k on time evey time pulled the head at 120k cross hatching didn't look that good
Could be junk oil filter, junk air filter, etc
@@alonzo5800 mopar oil filters AFE air filters truck had run 800hp for two years before i pulled the head
Is this you full time job?
UA-cam or working on trucks? Wait, never mind the answer to both is no.
So, how much for the long block?? Man if you were closer I'd be helping ya! Just finished my 12 valve build
THROW IT IN VERONICA!!!!!
Gas truck will stay a gas truck, ls swap perhaps
add nos
They were built to handle lots of heat from stock emissions bs
you do realize HP doesn't exist, right? engines produce torque, and torque only.
