I’ve learned more in 20 minutes about the engine in my truck than I have in 10 years. Thanks Gail!

[@SlapstickWebb]

Just how casual he says hopefully it’s fed by a Banks Ram system while breaking down a motor says so much about his ability to be a salesman as well as a professional builder

[@yellowrhyno]

The only one that can have this brand new engine sit for a decade and then remind us that his parts are still better. Absolute legend.

I love that Gale just casually drops “OG” in a video.

[@OrionsKelt]

Holy freaking complexity Batman. That thing looks like it would absolutely suck to work on. Impressive though.

[@sounboy4498]

The Ford F650/F750 from 2016 and Ford preform very well with this engine, I've replaced a few due to the Crankcase filter getting clogged and causing a high crankcase pressure that either cause oil leaks, blowing a turbocharger and burning all the oil in the sump. Have to pay attention to those little things, but I have one in the shop with 700k plus on it only in for a high pressure fuel pump on original engine!

[@winstonholmes5566]

700k. That’s child’s play for a Cummins.

[@sounboy4498]

@winstonholmes5566 I've seen good and bad cummins, presently have an ISB that dropped a valve, and it only had 39k on it. Is that childs play?

[@thahitman2]

It's all about maintenance and also there are always some that come with a defect or issue from the manufacturer. Cummins are ok older ones I think were a little better but the rest of the truck is garbage and gonna fall apart plus your gonna have to rebuild the trans and front end every 70K. I saw a F550 come in with the early model 6.7 had 1.5 million on it stock block and heads.

[@winstonholmes5566]

Look at the cost to mileage ratio for each engine, or yearly maintenance costs. The Cummins is going to have an far lower failure rate and costs and go way longer.

[@winstonholmes5566]

@@thahitman2once you build the transmission properly with good parts and shift kit that’s it for life. As for front end they all break and the dodge ones are easy and fast to work on. No stupid vacuum hubs.

[@treadlightlyservicesllc.1930]

to hear Mr. Banks praise a ford engineering design multiple times and be impressed is a thing of beauty. i cant wait for the tear down of the 2024 scorpion H.O. engine to see the updated turbo, and steel pistons..then we wanna see Gale push one to its limits and see what are the failure points.

[@tangydiesel1886]

Ford had a voluntary update for the early 6.7 engines that they would reflash them for the higher hp/tq levels. I have an extremely early '11 (made June 2010) that got the update. They look complicated, but they're a dream to work on vs. the navistar 6.0/6.4 engines.

[@kyles7584]

Long overdue, but glad to see the video Banks. The 6.7 Ford is a pretty interesting motor.

[@flip240]

Love hearing him talk. You know he's knowledgeable about not just engine performance but the true engineering behind it. And he's not just reading off a script. Very few "car" people on KZbin can do that.

I always love how Gale will take you back in time with some of the most simple components. It tickles me since I'm still dealing with military Avionics from the 60s lol (new platforms as well) . I have to look up the many years of standards changes for SAE, axial tolerances for ball bearings down to 1/1000th of an inch etc. He speaks my language and I enjoy how he explains everything. I could just listen to this guy talk forever.

[@dougbunyard2724]

This is sooo interesting! It's nothing short of amazing how you are able to explain complex systems and principles in a way that is fairly easy for a layman to understand. Also your enthusiasm is very evident and inspiring! Not sure if you read these comments and this is off topic here I know. I'm putting together a 5.9 24v and based on what I've seen on the Tube I'm planning on using a compound turbo set up. Daily driver and occasional equipment hauler.. Any thoughts on the compounds? New to the channel and loving it!👊

[@tomp538]

Gale thanks for making this video. I'm not a diesel fan; however I do admire the creativity, thought and engineering that went into this engine.

[@solidscamper]

Gale, The main thing I think of when watching this isn't why did it take you so long to tell us about the powerstroke compared to the isuzu that you normally talk about. Ohh...sorry Duramax, General motors "name". Who is going to do the explaining next? The legacy you are leaving is incredible. Thank you for all you have done for us who are hot rodders/motorheads. I recently purchased a 6.0L powerstroke excursion, and I can see the appeal and the reservation. My current thoughts are on swapping the body to modern 350 or 450 powertrain and chassis due to the improvements the automotive industry has made overtime. Without your explanation of how these motors are designed, and the engineering improvements and challenges, I would have many more questions than I do. Thank you!!! Keep up the great work. And I thank you again you remind me of my grandfather, my wife and I discuss the differences between your generation and my own. I belive you to be, in the post war generation, and I am the middle of the millenials. Your contribution to modern day tech is fantastic and I thank you. My grandfather had a video recoder, yes shoulder carried camera. As soon as he the video recorder, he walk around the city documenting how technology allowed them to reline the septic system in the 2000's. Thank you Gale, you are an example of the generation that has lead the way.

[@pointlinesquare]

Awesome video Gale. So much passion, information, history and that is one clean shop! I have a degree in aerospace engineering but was never really a "car guy". I drive a 1993 toyota with a 3 litre 4 cylinder turbo diesel... I don't think it looks like this inside!

[@funone8716]

Wow been a long time since I went into sponge mode and got some Banks school'in on engine tech. Just amazing when Gale does each and every video. Thank you Sir.

[@ugotsmacked1]

One thing to add on the oiling system on these motors, watch Daves Auto video on the 6.7 powersteoke. He came up with a solution for the oil drainback issue these motors have. 5-8 seconds to get oil pressure to turbo after starting. It was a good watch. Im assuming its a check ball or something along that line.

[@deanharris7149]

THANK YOU!!! Ford treats everything about this platform like its sorcery majic only available to its sorcerers. What’s the deck height? What’s the max over bore? Can it be bored out for wet sleeves? Cam specs? Etc. Eventually I, or someone faster with more money, is going to bore one out, sleeve it, and run Cummins 6.7 pistons for 7.75 liters or Duramax pistons for just around 7 liters. Sled pulls here I come!

That double lifter design is really, really interesting. Those style HVAs have been used in a huge number of European (and now pretty much all) engines over the years with great success, but I never expected to see them packaged into a roller lifter body!

[@reason2gether]

I know it is cool to see the maximized space utilization and obviously CAD Design potential, but I am a big fan of Keep it simple smarta$$! Gale, I would look for someone else to reassemble that mess also, after having the fun of taking it apart! Thank you for the inside look at what the engine designers are doing there at Ford. They must have a lot of fun working there as they ponder what the technician forced to repair that design has to go through and the choice of words, they would have to describe it! Happy Mother's Day!

Do this with more engines please! So cool to see! I'd love to see you do it with a for 6.0 and 6.4... That is if you can find one not already blown up.

[@Jim_Lawrence]

I'll assume part of that intake tract is for runner length and creating low RPM torque. Basic engine design that has escaped diesel for decades. It's pretty obvious the design was for a set RPM range, which is why the cross sectional area is as it is. It wasn't designed to be a 5500 RPM race engine. It made more of a 7.3 power curve than a 6.0 power curve.

[@01Z06guy]

Neat stuff, Ford. Since I'm the one working on and paying for parts on my truck, I'm happy with the simpler Cummins. I'm happy that this developement and compition exists though.

[@SM-og9pt]

In gas turbine engines and APUs oil is used to cool ball bearings to due to the heat generated both by friction and the hot environment. If they get too hot then you’re going to skid and have a bad day. Reducing friction in the ball bearing is a secondary concern.

[@davidneal377]

I love how the turbo on my 2011 sounds and pulls . They should have stuck with it ,and perfected it .

[@cjespers]

Those long oil passages drain back after sitting. Runs dry for a while. A check valve in the pickup tube may help, in my testing. Thanks for the video.

[@truracer20]

@22:00 there's lots of profit margin. Back then I was specing out a new truck and first I spaced it out with a 6.8 V10, then with the diesel, the diesel was the cost of the gas engine truck PLUS the $15k additional for the diesel...

[@user-rq2yk3rr6v]

Genius pure genius! Love my 2016 6.7 PS it’s a beast on a diet!

[@jeremiaswitt1374]

A year ago I was thinking about the powerstroke 6.7 and structurally it has everything 6 bolts per cylinder in the heads 6 bolts per cap to hold the rotating assembly, (this is the first powerstroke designed by ford and they did it with all the effort) it has its drawbacks like the cp4 fuel pump (called a hand granade) I mean: it has all the potential to be a great engine

[@danieldimitri6133]

As whacky as the intake tract is all tied into knots with cold air going to v mounted turbo, outside the engine, and back into the middle then down and out around the outside of the head and back inward to the valve its still pretty straightforward to assemble and less messy than a 6.4 with dual egr coolers and goofy oil activated injectors. Its also nice that they use hydraulic compensators which appear to be the same as the stationary ones in the modular engines. Keeps noise and scheduled maintenance down vs solid lifters common to diesel engines. They use 2 pushrods so they don't have to have rigid rockers with pivot pin wear issues or those balance bars common on diesels. Some things on these might be possible to simplify but its certainly not the worst thing out there.

[@TomConklin]

I love how Gale explains the inner workings!

[@korn111685]

Any opinion on speed of air pistons Mr. Gale?

[@jamest828]

Lots of old heavy duty diesel engines used a valve yoke and it was a valve bridge with a guide rod in the middle, that would solve your problem of unmatched valve spring rates
