Turning a junkyard 12-Valve Cummins into a 600hp POWERHOUSE: full DIY build!

[@christopherharris6005]

Awesome video as always Travis and Rick. Your dad is Infinite book of knowledge soak up as much as you can while you can. He’s such a cool dude. Also Travis the wrecker idea could be a future project for you and your son or daughter.

[@elispomalesmorales9662]

Every moment together with your dad is priceless. You never recognize what you have until you don’t have it anymore.

[@CruisinWithKevin]

Thanks for the shoutout it was great meeting you! I love your channel and the content you have it’s amazing!

[@theetravisb]

Thanks man good meeting you 🫡

[@robertwest3093]

CruisinWithKevin’s channel is seriously underrated. I don’t understand why it hasn’t taken off because he has definitely put in the hard work.

[@CruisinWithKevin]

@@robertwest3093 thanks Robert appreciate the support man. Travis’s channel is awesome too and he’s a genuine guys I’m glad I met him and found it!

[@smarthome2660]

TY Dave, Travis, I think I know where the shuttering is coming from, at 1:09:10 you backed that screw all the way out flush with the inside of the cover. I am almost positive you need to adjust that in while running, to get rid of the shudder. At idle yo don't have enough air pressure to keep that rack from wiggling back and forth. Once you increase the throttle and intake air pressure, the rack stops wiggling. Think of it like valve lash.

[@nicholasgann2419]

Three turns in after initial contact of the foot rod.

[@thisisus.504]

Yes buddy. From the UK, do cherish all the Dad moments. My father died a couple of years ago from Alzheimer's and my mum passed away back in March. I'm 53 and completely broken by that loss. What I'd give for just one more day. Watching your content really helps. Magic. 😊

[@ConRodsAndRustedBods]

Shout out to Dave, the awesome neighborhood machinist! Great to have someone not only willing to help, but actually explain things to you. Thanks again Dave.

[@jarvisautofabrication284]

Don’t forget to address the killer dowel pin behind the timing cover on the front of the engine. All you do is make a small metal tab to put in front of the pin and lock it down with the bolt that is nearby to keep it from falling out into the timing gears and wrecking the engine, also on the jumpy idle, on the AFC housing, that screw that you backed out behind the diaphragm, if you screw that in just a little bit while it’s running, it should touch the rack travel movement and steady the idle. Good work on everything also. It’s always good to take your time and go over things few times to make sure you don’t forget anything.

[@Chr.U.Cas1622]

👍👌👏 Sounds very reasonable. He might have backed out the screw a little bit too much although the specialists told him to have it flush with the housing. Best regards, luck and health in particular.

[@theetravisb]

Yeah you could be right. Still troubleshooting it.

[@thomasgraham7871]

It would be sad to see all your hard work and money wasted if that killer dowel pin falls out DO SOMETHING ABOUT IT!!!!!!

[@patrickreynolds801]

I agree. I'd also question the over flow valve. The banjo bolt looking screw near the rack plug. Maybe the spring craving open at idle and causing a fueling issue. Idk

[@Brock_Landers]

​@@theetravisbI was concerned about the killer dowel pin when you were adjusting the timing and I figured that you would at least pull the timing cover to see if it has already been addressed or not. Also, I agree with the OP, I would adjust that set screw with the engine idling to see if you can smooth out that rough idle.

[@RayScrafield]

Travis, I get the biggest kick out of you and how amazed you are at the tools that I sold a bajillion of. That valve spring compressor, a K-D 2078 if I recall, was something that every good mechanic had to have in his tool box. Otherwise he'd not be able to replace valve seals on overhead engines. Well, at least he wouldn't have to stuff the cylinder full of rope to hold the valves up. I keep seeing stuff that I sold tons of and how amazed you are at all of them. Your Dad has a world of knowledge. I sure would love to sit and drink a beer with him and just reminisce the good old days. By the way, many of the guys would weld a 3/8 drive socket to the center of the handle on that tool so they could run it with an air ratchet or 3/8 impact.

[@theetravisb]

I just really like things that make my life easier. Yes my dads great

[@barnardjames]

Really enjoyed this one from the UK. I've just bought an 84 Land Rover 90 and it's my first diesel, so it was great to learn a little about the science, before attacking her with the spanners. Much appreciation for the great content.

[@williamkarenschrecengost8408]

Travis, this is a great video. You are a great teacher. Nice to see your father helping. What a dad.

[@josephdangelo1503]

Hey Dave hope everything's going great and your day thanks for being there for Travis and his dad. Dave's the man!!!

[@aidanrogers7101]

The shuttering is coming from your fuel screw screw it in while running to get rid of the shake

[@pakkelly]

Thanks Dave the Machinist! You are a rare breed of man who can make precision stuff to keep the country moving.✔

[@barrybgnathan4766]

Brought back memories of when I was an apprentice diesel mechanic back in '80's here in NZ. We only checked the injector spray pattern & pressure. Usually, we would send injectors & pumps off to diesel specialists to overhaul. I'm a fan of American muscle engines, whether it's petrol or diesel. Love your work.👍

[@KDlGG]

Back then making big power out of diesels wasn’t super common like it is today, just about everyone’s doing it now. So checking spray pattern and pressure was what most shops did so you were in the loop for the time. You’d have a migraine if you looked at some of these newer injectors 😂 especially HEUI injectors

[@Pugs72]

Man it makes me happy watching your videos. Especially when you’re working with your pops.. I’ve said it a bunch but takes me back when I would help my pops in his shop restoring Harley 45’s. If you need a place to crash on any adventures into so cal hit me up. I have a travel trailer in my driveway perfect for a place to S-S-S. (Shit shower and sleep) always a great day with a new video! Keep up the awesome content! And a shout out to pops for passing down his knowledge to the next generation!

[@theetravisb]

Haha thanks for the offer man.

[@Ronald-n4b]

Good video as always thank you kindly. IT is truly amazing how you do things and so smooth at it. You are truly a craftsman. I'm almost 70 years old and I learn new things every time I watch. Thank you kindly again.

[@theetravisb]

Thank you appreciate the compliment

[@Mariano.Bernacki]

Cherish every moment with your Dad while you have him. You are also going to be a dad. Wear the seatbelt.

[@johnkendrick7304]

I was going to write a post in before I could I read yours and it was exactly what I was going to say. What else can I say

[@robertwest3093]

Travis’ dad in my opinion is the type of man that anyone would be proud to call their father. He also gets bonus points for being as engine savvy as he is.

[@howardkoster4026]

Very well put.

[@adamkyle7645]

I bought the same kit that you bought same hp package. I haven't bought the head studs yet but I have been waiting to install it. I bought the 3 piece exhaust but I wanted to put my egt and fuel pressure gauges and boost gauges in before I install the hp package. I just wanted to get baseline information before I started making any changes. I was just curious if you found out what the idle issue was yet to cause the racking that pdd described or any other issue it could be. My first thought was I was wondering if your fuel return valve needed to be adjusted for added fuel at idle or vice-versa just my uneducated thought. I also just wanted to say I enjoyed seeing you and your dad together. Mine is currently on hospice. So, as everyone has mentioned before me. Cherish your time together. We never know if we have tomorrow. Thanks again for your video.

[@patrickreynolds801]

Agree. Lost my dad two years ago. Nothing fills that hole.

[@metalmangle]

If you don't have the tool, make the tool. I love it. Super detailed, super interesting. Great video, Travis!

[@bigmurph1447]

Best injectors u can buy for a 12v is from Lanny at dynomite diesel performance. I been running 12v for close to 20years. I have tried tons of different injectors even ones from power driven diesel. Lenny's injectors are the best you can buy. They burn so clean. I have also tried tons of different parts for 12v's power driven diesel parts are ok but not great. I have a 96 12v with a set of compund turbos I have no idea on the power but it makes 65psi boost in a blink of and eye. I have lots of spare part from over the years. I got a big cabinet full of transmission parts from over the years. I do all my own work. Even rebuilt my own transmission and did a bunch of transmissions for other guys. I enjoy the Hobbie

[@stevelangston2359]

Dave is the man! Take care of him Travis! This whole video is a labor of passion and I really appreciate that!

[@sfcbrick]

Travis, I would call that an absolute success!!! Thanks Dave. And love watching you and your Dad!

[@foxstrangler]

This is great, diesel pumps are black arts to me. Now I know how they work, even though I will never work on one. Great to have Dave on again. He is da man when it comes to serious machine tools.

[@tomhiggins1124]

Thank you Dave. I had a good friend who lived in Cave Creek very much like Dave. He was also a machinist and just a wonderful man.

[@fastlifeadam]

id keep fine tuning the afc housing

[@kevinvremanconstruction5845]

Dave is the man!!! Nice video Travis. Cheers to your dad too.

[@theetravisb]

Yes he’s great.

[@Nzchimeran]

Dave's the man. A real engineer. Hopes he has passed on a few skills to the next generation. We can't lose those skill sets. 👍

[@theetravisb]

He knows his stuff he’s awesome

[@millguygarage4875]

I plan on doing this to my 1960 C10 ! Thank you for listening all the parts ! 🎉

[@KurtKoster-s6t]

That's a huot top box , I have one just like it, bought it in 1972

[@hendrickalexander4259]

My dad was a Ford head he loved the Ford F 100,and was so proud on earth of them

[@robertwest3093]

I never thought I would see the day where the diesel engine would become a performance engine. The power that you can get out of these things is downright impressive. Considering that they are so overbuilt from the factory it makes it easy to turn up the power without having to rebuild the bottom end with aftermarket parts.

[@theetravisb]

Yes these engines are really amazing

[@tomnorris2681]

Another great video, thanks to Dave, what a great dude! And also good seeing your dad

[@1979Malibuick]

Good looking out Dave! Putting the Bridgeport mill to work!

[@nicholasgann2419]

28:15 time of video. If you spin the valve on the pop tester out a lot and then pump it up close to the pop tester pressure you can the thread the valve in to slow down and watch better when the injector pops. As you turn the valve wheel in the pressure will increase until it pops. Just and fyi that I learned when using the same tester. 😮

[@kennethebenhoch9765]

Thanks Dave. You’re the best!

[@joerosier6059]

Another very interesting to me diesel hop up video. I know nothing about diesels so this was very educational and entertaining to watch. Looking forward to seeing the rest of this build!!!! PS: Next to diesels, the next thing I know nothing about are automatic transmissions. All I have ever done was pull them out and reinstall trannies rebuilt by somebody else. The most I have ever done was replace some solenoids on the valve body of a Chevy Astro van I owned. Can't remember what all I did but it solved the problem. That was about 15 years ago and my memory isn't what it used to be. LOL!!!!!

[@theetravisb]

Transmissions are crazy you’ll like the next vid on this build

[@CruisinWithKevin]

That’s what I thought too I’ve worked in diesels too but never hopping them up so this was really interesting!

[@steaviemorrow8151]

While you have access to it id recommend changing that rear freeze plug as well. Either a plated freeze plug or a coolant bypass kit. Once i started adding power to my 12 valve it blew that plug out and its a PITA to change with the body on!

[@ramonrivas2606]

Thank you so much for helping Travis Dave you rock brother 😀

[@billholemo2518]

Use an infrared thermometer on the exhaust runners on the manifold at cold startup to find a nonfiring cylinder .

[@toddbritton3221]

Thanks Travis for another great video and thanks Dave for being a great neighbor 👍👍👍👍🏁🏁🏁🏁

[@jamesstansfield265]

Thanks Dave. Engine looking good

[@johnkendrick7304]

Dave is what makes America great. Very very smart man. Completely underappreciated in my opinion, not by you just in general

[@nicklutz61]

Swap it into an old Caddy hearse - like a 57-60. Bring 'em back alive! Congrats on the little one on the way. Keep the vids coming!

[@brendanhayes2752]

Glad you found Dave, Cheech and Chong have been looking for him since the. 70’s! Great to have friends with skills. Enjoy the channel.

[@feltav5719]

the position you grinded that groove gave me chills... think about the worse scenario always

[@BerlinUpper]

Really interesting and super well explained! It's nice that you take the time to go into so much detail and don't just put out "will it start and drive" videos!

[@theetravisb]

Thanks glad you enjoyed the more in depth stuff

[@kanzerberox]

Changing the timing does not change the camshaft performance. I mean now the permannency of valves has change so it is normal that the idle would change. Great video!

[@Brock_Landers]

Wow, those guys did an awesome job with the foundation blocking. You'll be SO much happier with that than vinyl skirting. The vinyl skirting just always has issues.

[@dawngunny1112]

Great DIY rebuild, the details are fantastic, another great video Travis

[@theetravisb]

Glad you liked it 🫡💪🏼

[@dawngunny1112]

@ indeed i did . Most guys skip the harder stuff off camera and make stuff look way easier then it is. You sir will mention anything done off camera and catch us up. That sets you apart

[@TheNearlyFamousMrHobby]

Welcome to the world of P-pumps. Check fuel pressure and get rid of that OEM banjo fitting on the return line coming out of the pump. You have air in the system in the p oump. A new fuel return banjo should open it up.

[@EastonStroh]

Im not going to lie this might be the most entertained I have ever been, you are a great KZbinr and I love how you respect other people and have that neighbor relationship where it’s out of being a good guy and not about money. I appreciate you explaining everything and showing the specifics. I wish people like you got the viewers and followers you deserve because you and the people in this video are truly great people. Coming from a powerstroke guy I loved seeing a Cummins 600hp build. Thank you for all you do!

[@theetravisb]

Man what a great comment thank you 💪🏼💪🏼

[@iamrichrocker]

Christmas came early, but with some major ka ching...but your smiles as you unwrapped them was cool ..

[@waynelandeck6878]

Thanks Dave!!!!!!😀😃😃😃

[@rickmonte88]

Great detailed video. Don't forget that coolant plug "freeze plug" in the rear of that engine.

[@RayBenson45]

I have the same tool for valves it was my grandfathers he worked for ford in the 1950s and 1960s great tools to have

[@williamconner9407]

I'm not even a Mopar guy but this is gonna be a killer build

[@ghouliesgarage3922]

Thanks for taking the time to explain things Travis . I just started learning about Diesels ( never too old to learn something new ) Really epic video! Can't wait to see what you pick for a Body ( I'd pass on that shell as well ) Godspeed !

[@mfc4591]

My heart sank when the file broke, but, man, were you lucky to retrieve the broken piece! Some great progress was made , well done

[@christinawiseman-gc9jh]

That was a very interesting video. I learned a lot of things about injectors. We bought a 93 Ford f250 with a 7.3 l diesel un aspirated and it ran like a Swiss watch and still does. But we had a little crack in one of the caps to the injector pump or from the injector pump? I don't really remember just a little hairline crack where it was getting air and it would miss and high RPMs. It pump fuel fast enough that it wouldn't, but once the RPMs were down low it was getting a little bit of air into the injector. At least that was our problem. Just food for thought Good luck figuring this one out. Watching you from Yuma

[@michaelcamuso5461]

Looking forward to the transmission rebuild video. Great video.

Great video Travis. One of your most interesting ones although they are all great. Admire your knowledge and dedication. Definitely a shout out to Dave & also everyone in your video, nice to see all those old tools & especially made in the USA. Enjoyed watching. 👍🏼👍🏼

[@theetravisb]

Thank you means alot this one was pretty in depth for me for sure

[@geoffreyb3337]

I’m always so happy when I see a new video from you Travis, especially a nice long one like this I get to watch the first half on the way to work in the second half on the way home to help me relax❤

[@jeffhutchins7048]

You're supposed to check/set the valve lash pretty regularly in 12V Cummins. They're solid lifter motors.

[@garywilson12]

thanks to dave for his machining work and great work on the diesel engine, youll get that misss figured out

[@ajre9466]

Absolutely amazing skills and attention to detail so enjoyable to watch

[@martink.4659]

Travis, awesome video! You have to make sure that the body you want to put on that frame also has the height. Those cummins are very tall, just something to consider. Ever thought about a van?

[@toddjohnston4788]

You the man DAVE! GREAT FRIEND AND NEIGHBOR 😊

[@ejenterprise5540]

Might wanna consider a new damper while you’re in there, esp if you anticipate high rpm. Great channel thank you 👍

[@JeronWhite]

Great job dave

[@scottjones1497]

I do believe that Travis is going somewhere. Good job

[@thomasisherwood9756]

[@MegaKnutten]

what a wonderfull channel,realy respectfull with no swearing witch means alot to some1 with faith in jesus. You have my subb thats for sure

[@theetravisb]

I’m glad to hear that

[@Anthony12valve440RB]

I highly recommend a steed speed or just a 3 piece exhaust manifold. The stock ones start to shrink over time and will break off the ear on the head.

[@matteoazuni3274]

Amazing project, can't wait for the next video, thank you

[@rockinghorseexplorationand5504]

Hi Ray from Wisconsin here, luv da vids, thank you Dave!

[@hickoryhillangus]

Easiest engine to up the horsepower easily. And they are strong enough to hold up to much more power. First thing to go would be the headgasket on stock headbolts.

[@chrish1673]

Impact screwdrivers come in handy big time

[@melhopper-h5p]

what about coe truck? lots of cool ones out there. love your channel and thank you dave.

[@werewolfpig114]

Oh boy when I saw that file tool you made "thats gonna snap". My buddy made a knife outta one when we were kids, just by grinding and that was as long lasting youd expect 😂

[@brandonlisenby6752]

Just a heads up get you a liquid filled gauge for your injector tester and it’ll give you a more accurate reading.

[@yogithebear7493]

Fascinating the whole diesel motor with the whole inject pump deal

[@josephdangelo1503]

I can't wait to see what you're going to put it in??? Travis the things that we do because we weren't born wealthy, but it's all good fun and a great morning experience.

[@pakkelly]

One of the best videos on modifying a 12V for more power. Excellent up close filming and narration of how to…and how not to. That injector strip down made for great learning content even though you wouldn’t do it again. Keep us posted on the rough idle issue. If PDD says it is a jumping rack then is it something in the P-pump mods? Thanks for teaching us. Liked and subscribed.

[@dillinpicklesworth5698]

Even if you buy the whole injector, you should pop-test them.💯👍

[@gr00vechamp]

Hey Travis, did you notice there's a crack on the side of the engine block? It is located on the lip of a recessed bolt hole on the block. The crack is between the injection pump and the fuel filter. Look directly behind where the throttle linkage attaches to the rack.

[@benjaminkey22]

I am getting ready to do almost the exact build. Great video that showed me a ton that I have been wondering about. If you don’t mind me asking what was the total cost for the engine build? Thanks for the awesome video

[@theetravisb]

To reliably get to 600 on the engine probably looking at around 5k

[@robertspear9134]

Station wagon would be way cool !!

[@armandopatane5343]

Most older junk is much better ❤

[@johnellis3309]

Great video Travis a lot of work.. I've never messed with diesels I learned a lot

[@theetravisb]

There are pretty intricate little devils

[@feltav5719]

looove the model airplanes at your bud's shop

[@martinharris5017]

Diesels are a bit of a mystery to me so this vid wasn't just entertaining, it was also educational! I like your big shiny hair drier, should make some serious power. Can't wait to see what body you put over this engine.

[@lotuslotus718]

Great video only thing that I suggest you is when you’re working with timing and degrees are so critical you should lock engine from rear on the flywheel teeth especially if you’re torquing pump .There is tool like that it will fit inside starter whole it will lock directly into flywheel teeth. But you can make your own from scrap starter gear and some bolts.

[@theetravisb]

Yeah I shoulda had that tool honestly
