THE VIDEO THAT YALL HAVE BEEN BUGGING ME FOR FOR 3 YEARS. We take a apart a 6.7L PowerStroke Ford Diesel engine that was removed from a running truck with a skip in it. - Auta a dopravní prostředky
Just bought a 2018 6.7L F250 and that thing is an absolute monster. Ford has done their homework on this engine.
Same here. I agree. its a complete beast.
Aside from the ceramic ball barrings in the turbo
Bearing keys are used exclusively to locate the bearing. Bearing crush is what prevents rotation. Around 0.002-0.003" of bearing crush is typically employed.
Wow that's crazy how the airflow through the engine is reversed, very interesting design.
very old Cadillac V8's also exhausted out the middle valley
It works too damn good, as me !
Ford-Cosworth V-8's used in Indy Cars and F-1 cars had their exhaust in the engine valley and intake on the outside of the cylinder heads. What's old is new again!
About the rod bearing key. My Farm Diesel instructor back in the late 70's who has since passed away must came back as a Ford Engineer on the 6.7 project. He swore that it is only Bearing Crush that holds the bearing from spinning (It was in our John Deere Fundamentals of Service manual, it was a question on our test) The Key as you call it is only a locator.
He would be exactly right. The tang only aligns the bearings to make sure they are sitting properly in the rod ends. The actual holding force is the bearings themselves being crushed by the two parts mating together around them. When the bearings are put together inside the rod they form a circle slightly larger than the inner diameter of the connecting rod large bore causing a "crushing" effect that not only holds the bearings in place tightly against the rod but also keeps the bearings true to eachother even if the rod ends are not while making sure oil loss between the halves is kept to a minimum.
That little tang has never stopped a bearing from spinning, Dowels on the other hand are a different story.
I love this guy's videos. Even though I don't own a Ford Truck, or a any truck, I always learn somuch from him. Keep it up!
awesome!!! Been waiting for a 6.7 teardown! Nice work as always Mr Bill!
Good to see they finally made a decent oil pan.
2012 F250 I average 10000kms a month 300hrs got 103000kms on it so far only issue I had was DEF related frozen fluid...Very happy with the engine and transmission waiting to order a 2015 as a personal truck as well
Thanks Bill for taking the time to do these videos
Mario Slipac just wondering how many miles you have on your truck now ? 5 years laters comment on a comment 😂 thanks
Thanks Bill, forwarded this to my friend who just bought a 2012 F350 with 10K miles.
Hi Bill ... 96 Ford E350 460ci gasoline stealth camper, 200k and still strong... looking replace with another E350 2008-12. Was considering a power stroke engine, but thank god for your videos!! Not going near them! LOL... thinking to either rebuild or purchase a performance replacement.
In the past 2 days have watch over 12-15 of your videos and have enjoyed each one. This particular video about the newer purpose built was a superb analysis. Thank you for your efforts and energies. Even for us gasoline guys there is a wealth of tips and problem solving tactics. Good luck to you and yours
That thing is a monster! Wish they sold those trucks in the UK :(
Very informative video, I love learning about new engine technology!
Good video. One thing, the tab in a bearing is only there to keep it in place during assembly. Once the cap is torqued down a slight crush on the bearing is what keeps it from spinning.
Thank you Bill, Great video; waited a long time for this video and look forward to more.
bill is the man. learned alot from watching his videos.
Great vid I appreciate your expertise and knowledge that you share thx
Cummins has been using Aluminum on the 5.9 for 17 years that I know of. I use to work for a machining company that produced heads and front covers.
We need you to move your shop, employees, family, ect to Texas. There are more Ford trucks than you can shake a stick at.
I have been waiting for this video!!!!
hello, I like the way to look at the Ford. I am looking at buying a diesel truck and I'm new at diesel. I watched other channels but you one of the only guys talk about the truck, and the engine. Thank you.
Been waiting along time for this video. Can't wait to see some high milage and grenaded ones to start coming in. Should be soon considering all those factory warrentys should be starting to run out.
Great video, Bill! Have been wanting to see the 6.7 up close. Up to now, had only seen a couple of videos from JoeDiesel187 and they were in utility trucks that had destroyed cylinder heads on them. Looks like a very dependable power plant..
Bill, can you do a video on 6.7 fuel economy and longevity. Thanks for your videos, we've all learned a lot.
THANK YOU sir for making this!! ive been wanting to see the improvements that ford made with the 6.7 scorpion! in all honesty i cant find anything bad about them! ive seen a few with 200k miles with only turbo problems. all of them had the deletes on them so i have NO clue if emissions will mess stuff up. but seriously thank you alot!! ohh and thanks for all your video's they have helped a lot!!!
12:59 The key or tang of the bearing only serves to axially center the bearing in the rod. The installed crush (all bearings are made with a slightly larger OD than the ID of the clamped journal & are therefore ever-so-slightly interference-fit "crushed" into place when the cap is torqued) is what keeps the bearing from spinning. This is why bearings spin if rod bolts are not fully tightened, even with keys. Ford uses automated assembly or fixturing to center the bearings, hence no need for tangs. The mains are also tangless on this engine.
So true, the tang myth about it holding the bearing shells are rampant and people actually believe that! ive tried to explain it but people wont listen.
Cummins V style engines often use exhaust ports in the valley and the intake is where the exhaust usually is. It's cool to see ford doing this as well.
Excellent overview - thanks!
Awesome video, super informative, thanks Bill
You Sir are a Genius the way you explain in human language!
I've seen a lot of rod bearings spinning in the 6.7 just as you stated the only big problem I've experienced; wish ford would make an update.
I just have to say hi and great work I love your vids man. Thank you very much. Awesome
I gotta hand it to ford to build a motor that is damn near bullet proof. Hopefully they get the turbo issue figured out soon for this motor. Great video bill and keep up the great work.
You sir have my respect and I have learned a lot from this video thank you !!
Good stuff man!
I have to say it is nice to finally see someone that knows what they are talking about. If you can find a solution for the Navigation issue for my 2015 with 37" tires when you start driving the nav gets further off. Yes we programmed the tire size with a SCT. Still off! thanks
Great videos. I always learn something.
A valve cover leaking would allow the oil to leak into the intake port and if it got enough on top the piston that could have bent it.
Jonathan W not enough oil goes up there to gush into the port like that. The heads have drains in the bottom so it won't pool up while sitting. While running, it would burn up way before hydrolock. Most likely is a bad injector dumped fuel in
Excellent video, I learned a lot.
Dang Bill I must say Ford did their home work on this thing. I'm impressed with the design of this engine. Overall design shows prospect of reliability. Navistar dropped the ball the last couple of years. It never was a Ford issue just simply Navistar. If you haven't heard Navistar built an 11 and 13 liter Maxxforce engine and its bankrupting them on warranty costs. Glad ford has something now. Its been overdue for them. I hope Navistar comes out of it though. Love working on Internationals.
I am greatly appreciative of your research and feel great about my purchase of my 2017 F250 Super Duty. Thank you
A long time coming
have keys in the bearings doens't do much to stop them from spinning. The spread and crush of the bearing stop them from rotating in the connecting rods. when the rod caps are tightened down on the bearing, a huge force is exerted in all directions from the bearing. Therefore locking it in place by use of friction.
the lifter keepers break and the lifters twists in the bore on these and chew up the cam. when it comes to lifting the engine as a technician, ford specific tools has a plate that bolts to where the turbo bolts. also you do have to remove the lower oil pan to replace the oil cooler it has a nut inside the pan. it's a press fit bearing and the key does not keep a bearing from spinning. if the bearing wants to spin it will. the key is just for location.
as always your videos are invaluable to all of us
Thanks for all the info!
Great video, very informative.
Great video! See a lot of 90's M-B technology here. Crush bearings ( no tab ) have been used for a long time. Not sure of their benefit though..
Best channel on youtube , most educated mechanic ever ,excuse me for kissing ass, if you wouldn't mind posting fluids or maybe upgrades for the 6.7 more videos , I watch all the videos even though I only had a 6.7 and 6.4
I just got a 2019 6.7 lariat. I noticed a hanger under the dash and I couldnt figure out what it was until a while ago. It's to hang the 10 extra inches you get driving this beast!!
Nicely explained...thank you.
Ford is off to a good start considering they have not produced a diesel engine in their pick-ups until the 6.7. Give it a few years and this will be a nicely refined engine. Gotta' give Ford props for making their own diesel in-house.
Be very interested to see this alongside the 4l ish ford/range rover v8 diesel we have here in Europe. Bet there are some common design elements inside. It certainly looks 'ford' with the external oil cooler etc. Similar to a 2.0/2.4/3.2 puma zsd engine
Thanks Bill for sharing, do you know what kind of MPG this 6.7 gets?
luckily for the 2015 model year they are replacing and upgrading the turbo... should fix it..
Great knowledge!
Gosh i love bill. I really admire the way he expains things. "Balls turn to dust and granade the turbo" "they stole that design from duramax, i mean flat snatched from them" HAHA when traveling from brimingham alabama back to Nc i was very tempted to take the buford exit just to talk to him.
2020 looks like they got all the bugs out. Super Duty is looking pretty good Ford! A lot of progress
The register keys on bearings are only for assembly. What actually holds the bearing in place is compression force when the cap is torqued on. You may notice that bearings have a larger OD than the rod ID for this reason
Have you seen many of these 2 piece glow plugs failing? I have 995000 now and read I should change them before they fail and wipe out my motor.
Nice job, Please keep up the good job.'
upper pan does come off in vehicle, not too bad, done a few front covers for coolant leaks.
I'm curious how the new steel pistons will turn out. The aftermarket uses them for high power stuff, only downside I've heard of is that any failure will ruin the cylinders.
Hey Bill, i don't own a diesel i am a tacoma driver. You [along with diesel mud trucks] have made me want my own diesel!!! some day I hope to build, or modify a sick powerstroke. I havent decided on ford, chevy, or dodge yet...
Damn, what a nice engine !
Thank you for the information
I want one even more now.
Wow, ford used a few design ques from the old 4.0 SOHC that they put in Rangers. The oil spraybar they used in the 4.0s along with the two piece oil pan.
the tang doesnt keep the bearing from spinning it aligns the bearing. bearing crush is what keeps it from spinning
Great Review.
(Way better Designed Engine than I had Thought [I just wish the trucks weren't so expensive new])
Question though, what in your "Opinion" (rough guesstimate) kind of Longevity (if the turbo bearing issue can be permanently fixed) can we expect to see out of these engines?
So is the take-home message that the 6.7 is a well-designed and easily serviceable motor that I should immediately replace the turbo on? After that should I have a reliable motor? I have a '99 7.3 with 300k that I love, but am scared what to get next because diesel repairs are expensive and I have 3 kids (aka on a tight budget).
I agree 100% with the turbo problems. My buddy has a 6.7 Super Duty that he uses to tow his race car and he's on turbo number three. Ford does not want to issue a recall and there is no current TSB either. Thankfully it seems like his problems were only limited to the turbo (so far) and have not effected any parts of the engine. Other than that he said it's a fantastic truck. Drawbacks plague any brand and it is a bit soon to speculate, but for the most part these new 6.7s are doing very well. Truck quality is there like always with a Ford and the 6R140 behind it stole the spotlight from Allison if you ask me. Great video Bill!
what year is his truck?
TheMightyMatt67 2012
Thanks for the video.
Ceramic ball bearings in the turbos? What was Ford thinking? Very informative video! Thank you Bill.
That bearing key is only for assembly alignment, the crush from bolting the rod together squeezes the bearings and locks them in place
this guy is awesome
I got a 19 f250 super cab xlt 4wd gas eng .I'm impressed with this truck.6 speed trans .it drives and shifts perfect.quiet cab .I'm happy with it.4000 mi.test drive a gasser
Bill, i have a 2012 f250 6.7 and i want to buy a spartan tuner for what tune do you recommend for everyday driving?
The bare block looks so much like a duramax both good engines
They really did take a lot off the 6.6l
Strip the intake valve covers off and you have a duramax
They are changing the turbo for 2015 models
So I guess they know lol
Thats why I waited and bought the Goldie locks 2016.
Bill Question? were would i find training on how to rebuild the turbos. I can see that this is going to be a problem. I am a fireman and have a lot of time off and i can see a side "biz" out of this. thanks for any help
Bill, have you heard about all the problems people are having with the HPFP? Its looking like its a good idea to get a fuel separator/filter for it.
Finally ford has a reliable and relatively easy to work on Diesel engine. I swear ford trucks as a whole got 100x better in 2011.
A good engineer will not only learn from the failures of the engines he disigned, He will also learn from the success or failure of other engines build by other manufacturers.
Bill, please make a video on the differences between the three generations of 6.7L powerstrokes and the changes Ford made.
For what its worth the lift points are on pretty much all GMs as well. My 305, 2.0L, 3.5L, and 3.6L all have those two lift brackets for installing the motor.
Wasn't the turbo problem mainly on the 2011 F450? I thought I seen somewhere where the 250s & 350s use a different turbo from the F450.
Cyl identification did change, it is now numbered like other ford engines, pass side front to back 1 thru 4, drivers side 5 thur 8. And we have been seeing spun bearing and cracked valves all the time. I work at a dealer here in Alaska
Spun bearings are scary to me. Are y'all running the thinner oil up there? From Texas here, so same stuff all year.
turbo failures anything to do with injecting raw fuel through for dpf regen?
Are those lifters solid or hydraulic like the 6.0/6.4?
Lol, kinda reminds me of a LB7 duramax..... brand new engine, weak rods, and aluminum heads.
What is the chance that the shop that put the new long block into the truck that this engine was taken out of used the defective injector that cause the hydro lock in the new engine resulting in the same thing happening to the new engine.
Cylinder heads with the valve heads braking off the stems. Seen 4 trucks with the same issue in 2 weeks. 2015 will have a single turbo setup.
Just wondering if quite a few people that have problems have special tunes or have delete kits on their trucks? The people I know that have 2011 and 2012 trucks with 50,000 plus miles running stock have not had problems like I read about here.
How do the 6.7s from 2014 look going to go look at one in the next few days
Aluminium heads on landrover 200 and 300 TDI give almost no trouble as long as you keep water in it
If I recall I think from day one all Duramax heads were aluminum and they have been out since 01. The 6.7L seems to have the same great reputation that the 7.3L had, but its still too early to call it. I'd love to own a 6.7L, if I had the money to shell out to buy the truck.
Ya it was caused by fuel, some nut putting that dude above 600 hp or towing on street race mode from H&S or something like it.
Keep up the good work Bill. What do you think a few years later now?
I have a 2011 f 250 with 75000 miles on it. I put 50 this last year alone with one brake down I picked up bad fuel and had a mess. At that point I put the sparten on the truck running a 40 hp tune trucks intense now. Do you think I should upgrade my turbo after my last bill I don't Wana put a motor in this truck. Also I don't like the tuner besides the power I'm not a fan but need it for the egr delete intake and straight pipe. Any ideas on tuning for these trucks. Thanks man
Hi folks, Bill. Just bought the 2015 F250 Lariat with the 6.7. Only issue so far is that it sounds like a dang 18 wheeler taking off. All I hear is fan up until the turbo spools up then it settles down some. If im in a position where I need to pass someone and I nail it, it just sits on its ass and all I hear is fan and high rpm's. I would love for someone to comment as to this possible issue as I havent gone to any ford threads or dealer yet. Thanks!
You should of went to a forum before plopping down 65K. Im seeing alot of peps say spun bearing is an issue.Also when the turbos fail you have a 50/50 chance of crap getting in the oil galleys and taking out main barrings.The valve issue has been well documented seems to be mainly in the 2011/2012 models.All I can say is GOOD LUCK
Where is the Crank Shaft Position Sensor Located? Thanks!
I noticed that u were worried about aluminum heads on a diesel engine. Deutz built air cooled diesel engines back in the day and they had aluminum heads and cast iron blocks and they were really good engines most of them now are 40 plus years old now with thousands of hours on them now with little to no issues
