I am a Senior Master Tech at a Ford dealer and have been turning wrenches for over 38 years and one thing that grinds my gears more than anything else is getting in a vehicle that some hack wannbe tech has been into. When i am done with a customers vehicle you would be hard pressed to tell i have had it apart other than the normal telltale wittness marks on nuts and bolts. Your attention to detail along with your techs is quite impressive. Keep up the good work.
I wish there were decent mechanics where I live. That'd be amazing. Also, since you have 38 years and likely know more than I could ever dream of, do you know why my 6.7 sounds like it's knocking every time I change the oil? It's kinda loud for about 500-1000 miles after the change and then goes away. I can not figure it out. It's got 350k miles and has done that since like 100k. It drives me nuts. I dread changing it every time bc I'm scared it might be the last time.
Why would anyone want such a complicated diesel engine that requires a whole truck tear-apart.. for a engine problem is beyond me.. Cummins is so open and accessible.. never hear of cab removal.. waterpump pop the belts and two bolts! 45 min..start too finish in a driveway.
I have a 2012 Ford F250 with the 6.7 power stroke, all factory original. I have over 610,000 trouble free miles. I take very good care of this truck and never miss a service cycle since I have owned it.
@@justinwamshhhhhhh , you will seriously screw this man’s head up , if he has to face reality (yes it’s a driveway queen )and he really did get those miles and he needs to run down to the gas station and buy Idaho lottery tickets immediately!!
Dave’s Auto is the only shop on the planet I’d trust bringing my Mustang GT to have work done and I don’t let anyone else touch my car but me. I’m a full time mechanic (not a specialist transmission guy) but I took a vacation day to bring my car in and pulled the transmission myself and replaced the clutch and throw out bearing along with all the goodies you do when it’s out. Dave’s is exactly where you want to bring a vehicle that you love and need repaired correct.
I feel this man’s pain. My wife and I bought a used 2014 F350 stroker from a local used dealer that took in on trade. I did every thing right, carfax, independent inspection, etc. we only had it nine months when it ate a lifter. While tearing it down to investigate, I started noticing rounded bolt heads, mismatched hardware. Basically, someone who shouldn’t use a wrench was in that engine and fixed it enough for the guy to trade it in and run away with a newer truck. I never yelled at the dealer cause they were just as much a victim as I was, but $25K later and a new long block from Ford. I wish I would have known about you first cause “my friend” didn’t really do me any favors and left coolant clamps loose. Easy fix for me, but he’ll never touch my vehicles again.
Sounds like you did a good effort on checking on the vehicle before purchase. It's to bad we can't get all the maintenance and repair records on vehicles for a better picture
It’s just sad the level of dishonesty there is in this industry. I had the brake power block replaced on my wife’s 07 Navigator at Young Ford Ogden and they only hand tightened the lines on the block. Severe negligence at best. Who really needs the brakes to stop right. When I went in with the video proof from another mechanic they denied it was their fault. That’s why I like your videos, straight shooting no BS.
Not sure where the hell you guys are getting raped for a motor. My brother just blew his up at 300 thou and bitched to Ford about not being able to get a motor right away and they expedited a motor for $6800 granted that’s doing the work yourself but a lot better than 22 thou.
Nobody goes through life without having that expensive "Oopsie" moment -- just think of that $25,000 as a lesson learned and how much more knowledge you've gained that you'll be able to pass on to others.
I ran into this on a John Deere tractor engine. Big six cylinder and I don't remember which model it was. The tractor was a 4840. The first guy to work on it installed the cheapest brand of bearing he could find. The crank had been ground .010 oversize and had been polished correctly. But what I found was the bearings used varied in thickness. They were junk from brand new as some were thicker and some were thinner. The thicker ones pulled the the surface of the bearing off after only a very few hours and the motor lost oil pressure. The first guy "Assumed" the bearings were all the same. I am old school and all it would have taken is a strip of plasti-guage to tell the guy that something wasn't right. This is a cool video and you guys are fun to watch. I retired after 50 years so now I watch you guys and get a chuckle out of what you find.
Well, actually with power strokes that kind of modified from the factory transmission is modified to only go about 125,000 miles before rebuilding if you tow with it 80,000 those are facts
Hey Dave, I ground cranks every day for about 5 years. From what I see (hard to tell with a video), I agree with your diagnosis. Incorrect polishing can be a real issue. Only other thing could be if there was variance in the finished sizes of the journal/bearings. Where a big journal was paired with a thicker bearing and didn't allow for proper oil clearance
From what I've experienced, forged steel cranks do not have ferrite and cast cranks do. You are correct on your description of polishing. While working at Ford engineering they purchased a 2011 F350 with 806K miles. I was in charge of the teardown and prior to disassembly we performed some performance checks as well as leakdown and compression with all cylinders showing about 4% leakdown and only a 10 PSI variation between them in compression. Records from the dealer the customer had their service done at showed 2 fuel injectors being replaced at 500K with nothing else being replaced on the engine including the fuel and water pumps. The 6.7 uses a secondary cooling system to cool the EGR, fuel, trans, charge air cooler and power steering in lieu on having individual heat exchangers mounted at the front. When inspection was all completed, the only out of spec found was .011mm / .0005" at the top of some bores. This engine was very well cared for by the customer.
I don't even think the factory bores to much less than 0.0005"...that is ...well I suppose it is possible...I used Sunnen CK 10 with fine stones.. I could hit 4.125 + .030...to within 0.0003"...and even make the cylinder have a taper...
I think I've already cycled through almost all of Dave's videos. This is a company that I could go and work for free just to learn and tap into the mind of greatness. Keep them coming Dave!
Hey Dave, the cleaning guy at Jim's Automotive Service near Fort Collins seems to do a great job grinding cranks among other machining and assembly tasks. He is old school but not shy of new technology and is passing his lifetime of learning to his son. I think you two would get along great!
@@DavesAutoCenterCenterville You two are kindred spirits and should get acquainted with each other. Both of your channels are doing tremendous education for future shop owners, technicians and machinists. We need to keep this knowledge base going in this country!
Dave, I have had good luck over the years with crankshaft supply in Minneapolis Minnesota doing regrind’s. Good automotive machining is getting tough to find. As a retired heavy truck/bus mechanic of 45+ years I love your channel.
@@MrKennyanders i stayed up to date on all their announcements and last i heard / seen anything mentioned about it seems like they cancelled the whole show because the discovery writers wanted to add scripted / fake scenarios in the show and Dave was not having it. Props to him in my opinion, we watch these videos to see and learn nobody here wants there to be reality TV show elements added / drama.
Dave, the best crank grinder is at Jim’s Automotive Machine Shop. They’re a small family business running since 1983 and have a great RUclips channel also.
It would be interesting for them to do a joint video that both platforms can publish. A detailed look at crank grinding, failure points, best practices etc.
@@shaolinfist8323 Don't forget Keith Fenner and ABOM79. Slightly different subject matter, but both masters at their craft who lead by example on the right way to do things.
Well if you think about- people who should be driving these trucks are people doing commercial or their own business type of work who generate higher income on a daily basis. They will pay 15-20k for a new motor and maybe get that money back within a few days or weeks. At the end of the day these trucks make people a lot of money but at the same time cost a lot more to repair and maintain good. I never had luck with gas trucks. They are usually problem free up to around 200-300k they give out and you literally have to replace every part that's not the interior or the frame after that mileage. Diesels last way longer and pay off and make you more money. And are cheaper in the long run especially if you drive and tow and work with equipment ALOT. Just my opinion though.
Never ceases to amaze me how these Ford (probably others) diesel V8's are like a rubber band ball. The sheer number of bits, pieces, and harnesses that are just woven all over the engine is incredible.The amount of disassembly that has to happen before a regular guy like me can identify it as a long or short block is amazing.
Diesels need more components to run well as it isn't a ignition based.. not to mention alot of it is for the envoirment protection agencies rules to make diesel more eco friendly.
Remember the good old days when you could work on your own truck drunk, not have to remove the cab, and when you sobered up you could financially afford to fix it again?
@@OTEP1234567891011 No it's not. People need to stop asking for 600hp trucks. A 74 c30 dully made about 275hp gross to the wheels it was about 210 from a 427 big block. . How much more reliable do you think it could be if people are okay with having a 200 horsepower truck.
Best friends dad gave me his 04 Silverado LS and man I’m super lucky, he’s a retired fire fighter so he took insanely good care of it and one of the things that he did was write down EVERY single thing he’s done to it, every tire change/ rotation, oil change and any parts he’s fixed. It has zero leaks and noises and drives like a dream, gave it to me for 1500 too so yeah he hooked me up
I am no modern day mechanic by no means. I think you nailed it when you said cheap parts and bad workmanship. There’s no doubt in my mind. You guys will get it right love your videos y’all keep turning riches.
I am a retired mechanic (ASE Certified Master Technician with CA Test and Repair Smog License) with over 35 years of on the job experience. I really appreciate your channel and the videos you make. I love "Condition, Cause, Correction and Confirm." That is so important and the basic foundation of how a problem should be approached and repaired. I have a few questions and value / appreciate your time to answer: How are the GM L5P's Diesels and "Allison" 10L100'0's holding up? What are you seeing as far as issues with them? On the 6.7 Fords are you seeing much in the way of CP4 failures? Thank you so much, I look forward to future videos especially the follow ups.
My 2020 f350 dually 6.7 has 419k miles and still hotshot daily w it. Oil changes every 8k w 5/40 rotella. She’s a beast still running strong . I pull up to 28k behind it all day everyday
Hey Dave. Glad to see you wearing gloves. Your mechanic wasn’t and because I suffer from liver issues from being the same kind of guy as your mechanic I am very concerned for his future wellness. You sir Dave would be the best shop owner if you require that from your mechanics. It would show you care about their health… biggest mistake of my life and I share because I care
@@DavesAutoCenterCenterville from what I have read forged steel cranks do not have burrs like and cast cranks do directional polishing matters on them but do polishing all the same an no issues any how . just figured i ramble a bit i vote cheap parts bad mechanic sillycon mess helped 2
That engine was just worked o based on how clean it looks and from the oil pan so clean and fresh silicone. Alot of time's I've seen engine failures right after poor prior repairs.
Hey Dave the aftermarket is a filter for the the cp4 pump in case is exploded it catches alot of the metal preventing the tank and other stuff from being replaced they call it a disaster relief kit.
Dave, It's a S&S DPK -a Disaster(CP4 making metal sending it to entire fuel sys)Prevention Kit. Keeps CP4 failure from causing $10k in damage. It's the BEST insurance you can put on a 6.7 to prevent the disaster. S&S also makes the DCR Pump to replace the CP4 completely getting rid of that pos problem all together. Very simple swap, new pump actually flows a little bit more fuel and everything else is bolt-on parts. Any one with a 6.7 CP4 should have one or the other on their trucks unless they like spending $10k replacing entire fuel system!
I watch you all tear those engines apart and it absolutely amazes me that you can remember how to put them back together. I did a head gasket on a Jeep 4 cylinder and have to take notes and label everything.
Dave you are a man of integrity and honour there needs to be more men like you Sir. I am a Boilermaker intermediate Rigger and I definitely go out of my road to do the job right the first time the way it should be done. 🙏🇦🇺👨🏭
I see a lot of people knocking the 1st get 6.7 and i cant really see why to be honest. I bought my 2012 in 2016 with 193,000 on it for 27k, was a good price for being a loaded King ranch at the time. Got it home did some things involving a tuner. I never had a mechanical problem up to the day it got totaled. I ran the dog piss out of it pulling thing i shouldn't have been, and running it harder than i probably should have. I always did a cool down until the oil temp was under 205, did 5k intervals with 15W40, and 10k intervals on fuel filters. Truck had blow by from me running hot tunes but still started and drove fine. Got decent mileage. Now some poor soul in Alabama is driving it with a bent frame
You guys are awesome I can't believe you guys do so much work like that there are no mechanics like that anymore it is so special and awesome to see someone that actually gives a crap about what they do for their customers especially when you paid so much money you guys are taking care of it like it was your own car
The amount of detail I see you guys do on any engine that comes in is refreshing. I don’t know how many shops I’ve seen just throw stuff together to get it out of the shop.
Always interesting to hear you Dave. Good job. Have a good memorial day tomorrow. I will think to all thé Guy who came's in Normandy to keep my grand parent's free. Thanks to us
Absolutely love that bumper 💪🏻 That’s kool how the body is lifted off…WOW 👍🏻 Dave I love watching 🫵🏻R videos ‼️❣️❣️❣️❣️❣️❣️ In June 2017, I bought an 2014 Ford F150 V6, which had 34k miles. It’s got 2 regular doors and 2 other doors that open like the suicide type. It’s sun set metal flake color, ( Copperish ). It now has 96k miles, and I just 🫶🏻 my truck. I had left knee replacement on July 2, 2024, and haven’t been able to drive it till a day or so ago. Filled it with Tier 3 gas, and even though it’s really hot here in Louisiana ( heat index 110 ) running 60 mph it got 21.5 mpg , with A/C on max. Nothing in the long wheelbase bed. I’ve named my truck RUSTY….. THANKS DAVE FOR YOUR VIDEOS, THEY ARE OUTSTANDING ‼️ Wish there were vehicle repair shops of your quality way down here in Pineville, La. 👏👏👏👏💪🏻🇺🇸 8/16/2024
Regardless of how high the common opinion of the reliability of a motor is, there are still always going to be engine failures. The 6.7 powerstroke has a pretty good reputation overall but like everything else it has its flaws
Actually one of the local outfits close to where I work has a ton of them as fleet vehicles and statistically speaking, no they're not really reliable at all. They've had plenty of engine issues including two hardcore failures well before 100,000 MI, so many that they actually ordered a few Godzillas this last time around and then they were part of the issues that they had with the ignition systems on those and for 6 months, two of those trucks say unusable. The good news is they're learning. The two of six Godzillas have been replaced with two 6.6 lit gmcs. Soon to be more
@@ashes2ashes863 Weird, the company I work for has 10+ 6.7s and haven’t had a single catastrophic engine failure since 2016 when they were bought brand new (with some of them recently hitting 300k) but hey, “statistically speaking” is very subjective. And for the record, I am NOT a ford guy but those trucks have impressed me.
Wow great video Dave. It’s great watching technicians that are at the top of their game. Appreciate you filling us all in on the probable cause and methods of proper engine building practices.
I just got a new to me 06 Lincoln Town Car. It cost more than average because you can still smell just what clean and like new shape the car is in. It had 70316 miles and somehow all of the factory witness marks are still there like it just rolled out. The under side looked brand new like it had never been driven in the rain ever. I don't understand it even now after the 3000 miles Iv put on it and the few rain storms Iv been thru it's much more dirty. The dash had to come out so as to replace 4 of the 5 HVAC door actuators. Because of that problem I got about 2300 off the price so I ended up paying 11700 for an 18 year old Lincoln but I'd do it again. There wasn't a single spec of dust or anything like that behind the dash. The guy that traded it in really took great care of it. I could've bought 2 or three of them for that price but it was so nice I had to have it. It's all fixed up now and I got the car with the colors I wanted. I plan to keep it forever. I may even get a cheaper one if it comes along to keep the miles off this one but I did buy it to drive and indeed I do that. Often.
"Million mile" diesel truck days are over. These new diesels really just don't seem to have the longevity of the older iron. It's a sad state. And craftsmanship is something you guys are keeping alive. "No good crank grinders left in this country" just makes me sad. I love watching these because it gives me some hope that others might follow your example.
It is incredibly difficult to find good work nowadays. I have a pretty high standard, sometimes people make fun of me a little for it but I'm picky and my being picky works good for me. I literally can't find a machine shop in my area that does acceptable work they just do stupid things and ruin parts. I am knowledgeable enough to check their work and it's usually trash. I've worked at German shops on higher end German cars then the Volkswagen Audi dealer as a tech for a bit then I've worked at private shops on all sorts of things even on semi trucks for a bit but mostly passenger cars and trucks etc.. I actually like Chrysler products maybe not all of them but I'm also a jeep guy as a hobby and I'm very familiar with certain models. Last time I needed machine work done I had a short block for a jeep 4.0 that was rebuilt some years ago I've ran it in my personal jeep and it's a good engine but I wanted to put a fresh head on it because it had a bad seat and was also the wrong casting number for that block but I really wanted that engine going again so I figured they can't mess up a iron jeep head but boy I was wrong they ruined 2 heads luckily I have a large stash of parts but one of the heads was a really nice casting I was pretty upset not only was the valve job horrible and the head still dirty and full of carbon they crashed their machine into the thermostat gasket surface I don't even know how you do that then they said they couldn't fix it because it won't fit in their machine but I tried explaining you can't fix that if you mill it flat again I'd have to run a spacer to get clearance back and it's not how i do things. Then the other head was just so bad after they were done I scrapped it and learned my lesson it's kinda like when I have McDonald's every 6 months to a year the fries are good but I get a gut ache and realize why I dont go again. I used to be able to use local places and get work done and assemble an engine myself but I just can't get the work done locally anymore so I have other ways of getting things done I've cleaned up heads and lapped valves by hand and done valve seals or I know a couple places across the country I can mail stuff too. Don't even get me started on transmissions, when I started out I could get reliable rebuilt transmissions sometimes I'd find problems but not like you do today. Even those real expensive purple transmissions I've installed for people in dodge trucks and found problems like really dumb problems and serious problems. I started having to do repairs myself and I learned over the years with a lot of things to never give up the core until you know that your new part is good that has saved me when I end up just doing the rebuild it's much easier for me to take apart a core and rebuild it myself than to take apart a rebuilt transmission and try to fix someone else's screw up. But a few years ago I met an awesome transmission guy who works out of a little shop on his property he's highly knowledgeable and has become my friend. I love bringing him stuff and he lets me work with him on my stuff when I want something custom or I have an idea and he lets me do carry outs he's one of those guys that just spews knowledge. I love meeting and learning things from guys who are so good at what they do, and he understands how hard it is to get good parts and he is like me with his part sourcing so I trust him to find me stuff or if he says a used original would be better than new. I have a couple places I can work with through the mail I also have some friends that help me a little but I can't really do certain things on customer cars anymore in a reasonable amount of time because of the unreliable machine work and I'm not willing to half ass anything I want to make things better. One of my Hobby's other than jeeps is vintage dirt bikes and I found a guy locally who builds race engines for boats I'm not familiar with the boats or what he does exactly like what race team or where they race but I think he says they are mercury and he says they are 100k dollar engines the boats are really cool but he has a private shop and I have him do my bike stuff like crank rebuilding and some cylinder work I've also brought him my jet ski stuff. I also have another friend who has a mill in his garage and he does some stuff for me every now and then. But all that being said I can't just Google a machine shop and bring stuff there because of the high risk of things going wrong especially when it's a rare part I work with some very rare parts sometimes. I can think of a few places that have gone out of business over the years that I did good business with. One thing I'm sure other mechanics are familiar with is how horrible reman alternators and starters can be I think O'Reilly is the worst offender. I won't install an alternator or starter in a vehicle anymore unless I source it. I found a place called DC power they make high quality alternators even with fancy billet case options thats what I run in my Jeep. But why I mention this is we used to have a wrecking yard somewhat locally and they would rebuild alternators and starters and even do custom upgrades like higher output and this was built with new parts they just happened to be a wrecking yard too. I used them a hand full of times and I had a friend who used them a bunch but I really wish they were still around it was really cheap too like stupid cheap. But I'd love to be able to use someone like that again but there's just not a demand anymore to repair that stuff.
Sometimes for no reason at all really engines will fail. Some 6.7 power strokes are perfect and they have no issues ever. Mine is a 2019 that has worked very hard its whole life at 155,000 miles and the only thing that went wrong was the hot side charge pipe. Everything else has been flawless.
WOW! 6 bolt mains in that 6.7! Crazy Imagine, the Cummins still only has a 2 bolt main AND it makes the same power with 2 less cylinders..... And I'm a Ford guy. GREAT VIDEO GUYS
I tore a fb marketplace engine apart. It appeared it had been rebuilt but the rod caps were not marked so I marked all the caps, pulled the rod bearings out and they all looked pretty trashed, but cranked looked fine. After getting everything back from the machine shop, I assembled it and as soon as I torqued down the rod caps the engine was hard to turn. Tore it all back down and found that the previous “rebuilder” had mixed up all the rod caps, that was why the bearings were trashed. It took some time with a magnifying glass but I was able to match up the rods to the correct caps by lining up the machining marks. Put it all back together and it rotated just fine. I’m not sure how many miles they had on it after the rebuild but it had to have been really tight.
Good to know that super hero MEN are still out doing good in world while I’m having spine surgery on Memorial Day. Thank you Dave for producing excellent content and excellent product.
The RSC cups with the post it notes in them for the bolts is genius. And, a plus when you are finished with it on Friday and Dave brings in the keg of Coors for you all employees you can all have an RSC cup slug of beer 🍻 on Dave. Of course you will need to rinse them out first and have Dave take you home in his minivan if you fill the RSCs up more than twice. Cheers 🍻 😊
I was a GM tech in 1988, making $11 and hour ,flat rate. It sucked, I quit turning wrenches in late 89 and went to driving truck. You have some good mechanics, Dave.
Another great video. I have a 2017 with the 6.7 Scorpion and although I'm on my 3rd upper oil pan leak, I love the truck. She pulls my toy hauler like a champ up the steep grades here in SoCal to the desert. Now, I only have 76K miles on her but I'm sure she'll go many more since I change my oil every 5K miles or every year. Which ever comes first. In my opinion, I think the Ford 6.7 Scorpion is the best of the newer desiels out there.
Every single engine ever produced has some kind of problems. Operator error or lack of maintenance is the number one problem with any engine! This 6.7 scorpion engine has been produced since 2011 and there are literally millions of them out on the road every single day. Being there are sooo many out there you are bound to see them come into a repair shop from time to time simply based on sheer volume that's out on the road. It is a really good engine other that the Bosch CP4 fuel pump and the emissions equipment bs on it DPF, EGR, SCR, etc that choke it & cause more problems that their worth. Taking them off dramatically improves longevity & fuel economy (20+mpg). Diesels are just like other engines, they need their maintenance done religiously. Do oil changes & fuel filters regularly at 5k mile intervals & problems don't happen. There are many diesel trucks with close to a million miles or even more out there on the road doing cross country hotshot deliveries daily. Diesel is the lifeblood of the country & the world. Everything gets moved by diesel power -trucks, ships, trains, etc.
I'll stick with my 2000 F-250 Lariat 7.3 4X4... She ain't a Beast but 24 years of doing the scheduled maintance and front hubs, Big Blue is still running Great... Heck she'll still be running after the 6.7's have been scrapped :)
bro ive got to give respect to the camera guy or who ever had the idea to have this good of a camera and the editor not much editing but uploading at 2160p is nice
I find these videos so amazing What quality of craftsmanship and integrity Lifting bodies off frames as easy as opening a door. Would love to see a video of that process Best to Dave and the Crew John
The first I saw that a few weeks ago, lifting the cab up and away I was thinking what a lot of work. But then when I thought about it, it is a lot less work compared to pulling the motor through the hood if that is even possible.
Worked at Toyota Fremont Ca for 20 yrs ; the frame comes along conveyer line upside down , they put the wheels , gas tank in goes to a lifter ,up , then rolls over , picked up by carrier , goes to another lifter , down into the front wheel alineer ,out around to a diff line , down , add more stuff , lower the engine & tranny in , then the bed, then the cab , lifted up goes round to new line , add the brake fluid, - wheels- emblems - set down on floor conveyor add doors , go through water test - add the underbody coating , paint protection plastic , drive to parking lot , then rattle check on wash board track, back to parking lot ready for transport
Dave, I have a question for you based off a couple videos you have done in the past about the Ford 6.7 engine, I too have completed a few rebuilds of the Ford 6.7 and have found the same issue when tearing down the motors you have with engine oil starvation causing the extreme main and cam bearing and roller wear which usually is the knocking or ticking sounds coming from the engines if they are still running. In one of your videos, it appeared to me that you most likely installed a High-Flow, Low Cracking Pressure Check Valve in the pickup tube to prevent the oil drain back hence allowing oil to always be at the oil pump to start pumping oil pressure quickly, in this video when you were showing the different oil pans at the 14-minute mark I did not see the check valve, was this just a pan you have not completed this on yet or intend not to use? Do you install them on all the 6.7's you complete or did you say forget it and if this is what Ford did, and they designed this way, I am going to keep it that way? I just started a new rebuild the other day and currently the engine is in the machine shop, I am going to TIG weld in a High-Flow, Low Cracking Pressure Check Valve in my pickup tube but was curious if this is something you do or sell now also? Love the video, on a side note my vocational school teacher was also named Dave, taught us to critically think and this was 35 years ago now and not to just replace parts much the same way it appears to me that you are teaching your team of people there to be, and the reason to your success.
Dave, Great comment on the documentation of all that you notice not working and systems being modified. In my word of maintaining multiple types of propulsion systems, I call it CYA, (Cover your assets). Also, having a tuner on a truck is not the best idea. Some portions of the tune will give you better mileage, some tune adjustments will create havoc on the engine or the transmission. Why risk the havoc, use the truck as it was intended within its intended capacities.
At 12 years old, I guarantee I would've done a better job on that engine. Whoever tried repairing that engine needs some folded newspaper disciplining and sent back to school.
32 rocker arms, exhaust and intake reversed from the usual v8 setup. What a neat machine. It sounds like people seem to have lots of trouble with these engines but I can’t help but like the 6.7. Outside of 2 injectors, mine has been good so far.
that fuel filter is the absolute first thing anyone should do directly after purchasing any year 6.7 new or used a disaster prevention kit so when your cp4 pump grenades it doest cost you 10k to fix
I think why crank grinders are rare is because only aftermarket shops will go the extra step! But also its performance folks doing that work and needing a 2 day turnaround is not feasible when they have 30 high dollar builds lined up!
For the record the piston cooling jet was likely damaged during reassembly by the 12 year old mechanic and when a PCJ breaks off on a 6.7 a piston failure is immanent. Also if the upper and lower rod or main bearings are transposed this will need to the overplate being overloaded. The lower mains and upper rod bearings are coated with a special material to handle the firing load and the lower aluminum bearings are supposed to be installed in the block and rod caps.
@@sprint2648 im sorry but been driving these fords for 30yrs plus their always alot of issues for us i own 2024 f350 7. 3 we switch to all gas now much better we do like the trucks all f350-f550
A burned blue engine bearing and melted Babbitt material with an intact crankshaft journal can result from a combination of factors: 1. **Oil Starvation**: Insufficient lubrication can cause excessive friction and heat. The bearing may suffer the most because it directly contacts the journal. The lack of oil prevents heat dissipation, leading to bearing overheating, discoloration, and Babbitt material melting. 2. **Bearing Misalignment**: If the bearing is not properly aligned, uneven load distribution can occur. This causes localized heating and damage, even if the crankshaft journal remains unaffected. 3. **Improper Bearing Clearance**: Incorrect bearing clearance can lead to insufficient oil film thickness, resulting in metal-to-metal contact and overheating of the bearing. The crankshaft journal may still appear good if it was not subjected to prolonged or severe contact. 4. **Contaminants**: Debris or contaminants in the oil can cause damage to the bearing surface while the crankshaft journal, being harder, remains relatively unscathed. 5. **Material Defects**: The bearing may have had material defects or manufacturing issues, making it more susceptible to failure under heat and load. 6. **Heat Transfer**: The bearing can experience higher localized temperatures due to friction, leading to discoloration and Babbitt melting, while the crankshaft journal, being larger and better at dissipating heat, remains in good condition. In summary, the bearing is more susceptible to damage from heat and friction due to its material and position, while the crankshaft journal, made from tougher material and better at dissipating heat, can remain unaffected even when bearing damage occurs.
The clockspring could have spun when the cab was removed from the chassis. But i think yall are smarter than that, Ive had too many times ive fixed one thing and customers says that wasnt broken or that wasnt like that, So ive learned to go fully through someone's car before major repairs.
I am a Senior Master Tech at a Ford dealer and have been turning wrenches for over 38 years and one thing that grinds my gears more than anything else is getting in a vehicle that some hack wannbe tech has been into. When i am done with a customers vehicle you would be hard pressed to tell i have had it apart other than the normal telltale wittness marks on nuts and bolts. Your attention to detail along with your techs is quite impressive. Keep up the good work.
I wish there were decent mechanics where I live. That'd be amazing. Also, since you have 38 years and likely know more than I could ever dream of, do you know why my 6.7 sounds like it's knocking every time I change the oil? It's kinda loud for about 500-1000 miles after the change and then goes away. I can not figure it out. It's got 350k miles and has done that since like 100k. It drives me nuts. I dread changing it every time bc I'm scared it might be the last time.
That tech was tearing that motor down like it owed him money!
Well, he don't get paid to be on film calling customers... so... 😂
Gettin it
It does. He has to work on it, so it owes him.
Why would anyone want such a complicated diesel engine that requires a whole truck tear-apart.. for a engine problem is beyond me.. Cummins is so open and accessible.. never hear of cab removal.. waterpump pop the belts and two bolts! 45 min..start too finish in a driveway.
Very funny!!! Well done!
I have a 2012 Ford F250 with the 6.7 power stroke, all factory original. I have over 610,000 trouble free miles. I take very good care of this truck and never miss a service cycle since I have owned it.
Great to hear👍. Here's to many more trouble, free miles.👏👏
That is a 💯 lie
You give me hope 😅
@@justinwamthey go the miles if taken care of
@@justinwamshhhhhhh , you will seriously screw this man’s head up , if he has to face reality (yes it’s a driveway queen )and he really did get those miles and he needs to run down to the gas station and buy Idaho lottery tickets immediately!!
that teardown was feaking awesome, that dude was so in the zone doing his thing
You bet, that's Jason for ya. Thanks for watching.
Dudes knows where every bolt is before his eyes see it
And…..labels every bolt and files them away in a red solo cup library by the sequence he removed them. Jam up tech right there.

Will do!
Not only Men. 😉😉
Dave’s Auto is the only shop on the planet I’d trust bringing my Mustang GT to have work done and I don’t let anyone else touch my car but me. I’m a full time mechanic (not a specialist transmission guy) but I took a vacation day to bring my car in and pulled the transmission myself and replaced the clutch and throw out bearing along with all the goodies you do when it’s out. Dave’s is exactly where you want to bring a vehicle that you love and need repaired correct.
Absolutely 💯
I feel this man’s pain. My wife and I bought a used 2014 F350 stroker from a local used dealer that took in on trade. I did every thing right, carfax, independent inspection, etc. we only had it nine months when it ate a lifter. While tearing it down to investigate, I started noticing rounded bolt heads, mismatched hardware. Basically, someone who shouldn’t use a wrench was in that engine and fixed it enough for the guy to trade it in and run away with a newer truck. I never yelled at the dealer cause they were just as much a victim as I was, but $25K later and a new long block from Ford. I wish I would have known about you first cause “my friend” didn’t really do me any favors and left coolant clamps loose. Easy fix for me, but he’ll never touch my vehicles again.
Sounds like you did a good effort on checking on the vehicle before purchase. It's to bad we can't get all the maintenance and repair records on vehicles for a better picture
Buying a used diesel is like marrying a prostitute
It’s just sad the level of dishonesty there is in this industry. I had the brake power block replaced on my wife’s 07 Navigator at Young Ford Ogden and they only hand tightened the lines on the block. Severe negligence at best. Who really needs the brakes to stop right. When I went in with the video proof from another mechanic they denied it was their fault. That’s why I like your videos, straight shooting no BS.
Not sure where the hell you guys are getting raped for a motor. My brother just blew his up at 300 thou and bitched to Ford about not being able to get a motor right away and they expedited a motor for $6800 granted that’s doing the work yourself but a lot better than 22 thou.
Nobody goes through life without having that expensive "Oopsie" moment -- just think of that $25,000 as a lesson learned and how much more knowledge you've gained that you'll be able to pass on to others.
I ran into this on a John Deere tractor engine. Big six cylinder and I don't remember which model it was. The tractor was a 4840. The first guy to work on it installed the cheapest brand of bearing he could find. The crank had been ground .010 oversize and had been polished correctly. But what I found was the bearings used varied in thickness. They were junk from brand new as some were thicker and some were thinner. The thicker ones pulled the the surface of the bearing off after only a very few hours and the motor lost oil pressure. The first guy "Assumed" the bearings were all the same. I am old school and all it would have taken is a strip of plasti-guage to tell the guy that something wasn't right. This is a cool video and you guys are fun to watch. I retired after 50 years so now I watch you guys and get a chuckle out of what you find.
I never understood why people modify their shit half-assed and then are shocked when shit breaks down.
Well, actually with power strokes that kind of modified from the factory transmission is modified to only go about 125,000 miles before rebuilding if you tow with it 80,000 those are facts
Ignorance/ego.
See it all the time with boats. Being cheap will always cost you more.
@@AmericanSurvival001 What are you talking about? Ford makes the best transmission in the business right now. It's industry consensus.
I agree, many people buy a whole bunch of aftermarket performance parts that cancel each other out and you have gained nothing but headaches
Hey Dave, I ground cranks every day for about 5 years. From what I see (hard to tell with a video), I agree with your diagnosis. Incorrect polishing can be a real issue. Only other thing could be if there was variance in the finished sizes of the journal/bearings. Where a big journal was paired with a thicker bearing and didn't allow for proper oil clearance
From what I've experienced, forged steel cranks do not have ferrite and cast cranks do. You are correct on your description of polishing. While working at Ford engineering they purchased a 2011 F350 with 806K miles. I was in charge of the teardown and prior to disassembly we performed some performance checks as well as leakdown and compression with all cylinders showing about 4% leakdown and only a 10 PSI variation between them in compression. Records from the dealer the customer had their service done at showed 2 fuel injectors being replaced at 500K with nothing else being replaced on the engine including the fuel and water pumps. The 6.7 uses a secondary cooling system to cool the EGR, fuel, trans, charge air cooler and power steering in lieu on having individual heat exchangers mounted at the front. When inspection was all completed, the only out of spec found was .011mm / .0005" at the top of some bores. This engine was very well cared for by the customer.
I don't even think the factory bores to much less than 0.0005"...that is ...well I suppose it is possible...I used Sunnen CK 10 with fine stones..
I could hit 4.125 + .030...to within 0.0003"...and even make the cylinder have a taper...
Dave & his crew are definitely top notch when it comes to knowledge & quality. Love watching & learning from any & all of your videos
It’s amazing the amount of work and time that goes into teardown to find out the problem
I think I've already cycled through almost all of Dave's videos. This is a company that I could go and work for free just to learn and tap into the mind of greatness. Keep them coming Dave!
Hey Dave, the cleaning guy at Jim's Automotive Service near Fort Collins seems to do a great job grinding cranks among other machining and assembly tasks. He is old school but not shy of new technology and is passing his lifetime of learning to his son. I think you two would get along great!
Sounds great! Some others in the community have mentioned this as well.👍
@@DavesAutoCenterCenterville You two are kindred spirits and should get acquainted with each other. Both of your channels are doing tremendous education for future shop owners, technicians and machinists. We need to keep this knowledge base going in this country!
Great people
They sold out to shady sponsorships though.
Dave, I have had good luck over the years with crankshaft supply in Minneapolis Minnesota doing regrind’s. Good automotive machining is getting tough to find. As a retired heavy truck/bus mechanic of 45+ years I love your channel.
Good to hear from an experienced man. Appreciate the update on crankshafts.👍
I'm in MN
Might have to check them out.
The engineering that goes into a modern engine is mind blowing
Jason is the man. Dailed in, didn’t give a shit about the cameras. True professional
His disinterest in the filming makes him the perfect presenter, really. Top work Jason.
Do you think the Discovery Network thing is going to happen.
@@MrKennyanders i stayed up to date on all their announcements and last i heard / seen anything mentioned about it seems like they cancelled the whole show because the discovery writers wanted to add scripted / fake scenarios in the show and Dave was not having it. Props to him in my opinion, we watch these videos to see and learn nobody here wants there to be reality TV show elements added / drama.
Dave, the best crank grinder is at Jim’s Automotive Machine Shop. They’re a small family business running since 1983 and have a great RUclips channel also.
It would be interesting for them to do a joint video that both platforms can publish. A detailed look at crank grinding, failure points, best practices etc.

I love the teardown montage. Very interesting!
Glad you enjoyed it!
The music is actually really good!
Big boy toys...big boy repair bills. This kind of stuff makes me like my well maintained- high mileage GAS truck even more.
Well if you think about- people who should be driving these trucks are people doing commercial or their own business type of work who generate higher income on a daily basis. They will pay 15-20k for a new motor and maybe get that money back within a few days or weeks. At the end of the day these trucks make people a lot of money but at the same time cost a lot more to repair and maintain good.
I never had luck with gas trucks. They are usually problem free up to around 200-300k they give out and you literally have to replace every part that's not the interior or the frame after that mileage.
Diesels last way longer and pay off and make you more money. And are cheaper in the long run especially if you drive and tow and work with equipment ALOT. Just my opinion though.
@Selsigs ok lady
Agreed. My 2013 5.0 F-150 with only 87k will be my last vehicle for YEARS.
Never ceases to amaze me how these Ford (probably others) diesel V8's are like a rubber band ball. The sheer number of bits, pieces, and harnesses that are just woven all over the engine is incredible.The amount of disassembly that has to happen before a regular guy like me can identify it as a long or short block is amazing.
Diesels need more components to run well as it isn't a ignition based.. not to mention alot of it is for the envoirment protection agencies rules to make diesel more eco friendly.
Emission regulations killed the good old days.
@@billyc5914All hail the 7.3
At 4.11 in this video I felt traumatised. All this nonsense because it uses a ridiculous fuel. At 2024 we shouldn't be using diesel.
@@gb4408 Why not? Diesel engines are 100% fuel efficient, gas engines aren't.
Remember the good old days when you could work on your own truck drunk, not have to remove the cab, and when you sobered up you could financially afford to fix it again?
Sad it’s become complicated… who’s at fault.
I could sit on the radiator, put a foot on each frame rail and work on the shade of the hood.
@@theman9907
The EPA, mainly.

@@OTEP1234567891011 No it's not. People need to stop asking for 600hp trucks. A 74 c30 dully made about 275hp gross to the wheels it was about 210 from a 427 big block. . How much more reliable do you think it could be if people are okay with having a 200 horsepower truck.
Best friends dad gave me his 04 Silverado LS and man I’m super lucky, he’s a retired fire fighter so he took insanely good care of it and one of the things that he did was write down EVERY single thing he’s done to it, every tire change/ rotation, oil change and any parts he’s fixed. It has zero leaks and noises and drives like a dream, gave it to me for 1500 too so yeah he hooked me up
That 5.3 is a frik'n gem of a motor 👍🏽
Dave you are a breath of fresh air in this polluted and convoluted world we live in keep it up
I am no modern day mechanic by no means. I think you nailed it when you said cheap parts and bad workmanship. There’s no doubt in my mind. You guys will get it right love your videos y’all keep turning riches.
I am a retired mechanic (ASE Certified Master Technician with CA Test and Repair Smog License) with over 35 years of on the job experience. I really appreciate your channel and the videos you make. I love "Condition, Cause, Correction and Confirm." That is so important and the basic foundation of how a problem should be approached and repaired. I have a few questions and value / appreciate your time to answer: How are the GM L5P's Diesels and "Allison" 10L100'0's holding up? What are you seeing as far as issues with them? On the 6.7 Fords are you seeing much in the way of CP4 failures? Thank you so much, I look forward to future videos especially the follow ups.
S&S diesel has a new pump to replace the cp4 nightmare.
You need to upgrade the lighting in that shop. Those guys deserve a well lit shop to work in. They work hard as hell.
Get more tired with fake CFL lights. Wear a headlamp in daylight as needed.
My 2020 f350 dually 6.7 has 419k miles and still hotshot daily w it. Oil changes every 8k w 5/40 rotella. She’s a beast still running strong . I pull up to 28k behind it all day everyday
Hey Dave. Glad to see you wearing gloves. Your mechanic wasn’t and because I suffer from liver issues from being the same kind of guy as your mechanic I am very concerned for his future wellness. You sir Dave would be the best shop owner if you require that from your mechanics. It would show you care about their health… biggest mistake of my life and I share because I care
Dang man , Never heard of such a thing!! wish the best for you and may God be with you through you journey!
The ferrite burr explanation! Thanks for that! I never knew.
A crank is ground based on it's direction of rotation, too. A LH rotating crank will be ground (and polished) in the opposite direction.
Happy to help!
Something I had known but forgotten.
@@DavesAutoCenterCenterville from what I have read forged steel cranks do not have burrs like and cast cranks do directional polishing matters on them but do polishing all the same an no issues any how . just figured i ramble a bit i vote cheap parts bad mechanic sillycon mess helped 2
That engine was just worked o based on how clean it looks and from the oil pan so clean and fresh silicone. Alot of time's I've seen engine failures right after poor prior repairs.
Dave’s One of my favorite channels & Bellos Kustoms channel! Better than Anything on TV.
That silicon plugged up the oil pick up.
I love watching a channel where you actually learn something. This is one of those. Thanks
Hey Dave the aftermarket is a filter for the the cp4 pump in case is exploded it catches alot of the metal preventing the tank and other stuff from being replaced they call it a disaster relief kit.
Not sure how or why he didn’t know that. The weld on EGR plate is great!
Dave, It's a S&S DPK -a Disaster(CP4 making metal sending it to entire fuel sys)Prevention Kit. Keeps CP4 failure from causing $10k in damage. It's the BEST insurance you can put on a 6.7 to prevent the disaster. S&S also makes the DCR Pump to replace the CP4 completely getting rid of that pos problem all together. Very simple swap, new pump actually flows a little bit more fuel and everything else is bolt-on parts. Any one with a 6.7 CP4 should have one or the other on their trucks unless they like spending $10k replacing entire fuel system!
Just put a DCR pump from S&S diesel and totally eliminate the CP4 then you’ll have a good truck minus the emissions also.
Installed one today on my 6.7
As a new subscriber and a small fleet owner, I want to thank you for your EXCELLENT videos. Very well done and informative. Thank You!!

That was a mess. It’s tough when businesses need their vehicles and put off proper repair. Great analysis and rebuild. Thanks.
Not surprising to me. My 6.7 powerstroke blew up at 89,000 mi and was just out of warranty. $22,000 for a new engine.

Where on earth are you buying that engine for 22k?? Im a ford tech just curious
@@sounboy4498 from Ford. Gillette diesel did the work
@@sounboy4498 I guess I should clarify. The engine with labor was 22K
I watch you all tear those engines apart and it absolutely amazes me that you can remember how to put them back together. I did a head gasket on a Jeep 4 cylinder and have to take notes and label everything.
Great episode Dave. When my boss 6.2 goes it’s coming the 2000 miles to you!
6.2 Boss is awesome. Just buy a new one and drop it in, still cheaper than replacing the injectors on a 6.7
Dave you are a man of integrity and honour there needs to be more men like you Sir. I am a Boilermaker intermediate Rigger and I definitely go out of my road to do the job right the first time the way it should be done. 🙏🇦🇺👨🏭
I see a lot of people knocking the 1st get 6.7 and i cant really see why to be honest. I bought my 2012 in 2016 with 193,000 on it for 27k, was a good price for being a loaded King ranch at the time. Got it home did some things involving a tuner. I never had a mechanical problem up to the day it got totaled. I ran the dog piss out of it pulling thing i shouldn't have been, and running it harder than i probably should have. I always did a cool down until the oil temp was under 205, did 5k intervals with 15W40, and 10k intervals on fuel filters. Truck had blow by from me running hot tunes but still started and drove fine. Got decent mileage. Now some poor soul in Alabama is driving it with a bent frame
Dave is a leader. Not a boss. Cummins Milton Keynes in the UK need to take note!
well said mate
Now that's a comment
You guys are awesome I can't believe you guys do so much work like that there are no mechanics like that anymore it is so special and awesome to see someone that actually gives a crap about what they do for their customers especially when you paid so much money you guys are taking care of it like it was your own car
Opportunity knocks! Love your videos Dave. You rock!

Regardless of how high the common opinion of the reliability of a motor is, there are still always going to be engine failures. The 6.7 powerstroke has a pretty good reputation overall but like everything else it has its flaws
Actually one of the local outfits close to where I work has a ton of them as fleet vehicles and statistically speaking, no they're not really reliable at all. They've had plenty of engine issues including two hardcore failures well before 100,000 MI, so many that they actually ordered a few Godzillas this last time around and then they were part of the issues that they had with the ignition systems on those and for 6 months, two of those trucks say unusable. The good news is they're learning. The two of six Godzillas have been replaced with two 6.6 lit gmcs. Soon to be more
@@ashes2ashes863 Weird, the company I work for has 10+ 6.7s and haven’t had a single catastrophic engine failure since 2016 when they were bought brand new (with some of them recently hitting 300k) but hey, “statistically speaking” is very subjective.
And for the record, I am NOT a ford guy but those trucks have impressed me.
Wow great video Dave. It’s great watching technicians that are at the top of their game. Appreciate you filling us all in on the probable cause and methods of proper engine building practices.
If you're in southeast Idaho...Troy's machine in rigby is a perfectionist machinist.
I just got a new to me 06 Lincoln Town Car. It cost more than average because you can still smell just what clean and like new shape the car is in. It had 70316 miles and somehow all of the factory witness marks are still there like it just rolled out. The under side looked brand new like it had never been driven in the rain ever. I don't understand it even now after the 3000 miles Iv put on it and the few rain storms Iv been thru it's much more dirty. The dash had to come out so as to replace 4 of the 5 HVAC door actuators. Because of that problem I got about 2300 off the price so I ended up paying 11700 for an 18 year old Lincoln but I'd do it again. There wasn't a single spec of dust or anything like that behind the dash. The guy that traded it in really took great care of it. I could've bought 2 or three of them for that price but it was so nice I had to have it. It's all fixed up now and I got the car with the colors I wanted. I plan to keep it forever. I may even get a cheaper one if it comes along to keep the miles off this one but I did buy it to drive and indeed I do that. Often.
"Million mile" diesel truck days are over. These new diesels really just don't seem to have the longevity of the older iron. It's a sad state.
And craftsmanship is something you guys are keeping alive. "No good crank grinders left in this country" just makes me sad. I love watching these because it gives me some hope that others might follow your example.
It is incredibly difficult to find good work nowadays. I have a pretty high standard, sometimes people make fun of me a little for it but I'm picky and my being picky works good for me. I literally can't find a machine shop in my area that does acceptable work they just do stupid things and ruin parts. I am knowledgeable enough to check their work and it's usually trash. I've worked at German shops on higher end German cars then the Volkswagen Audi dealer as a tech for a bit then I've worked at private shops on all sorts of things even on semi trucks for a bit but mostly passenger cars and trucks etc.. I actually like Chrysler products maybe not all of them but I'm also a jeep guy as a hobby and I'm very familiar with certain models. Last time I needed machine work done I had a short block for a jeep 4.0 that was rebuilt some years ago I've ran it in my personal jeep and it's a good engine but I wanted to put a fresh head on it because it had a bad seat and was also the wrong casting number for that block but I really wanted that engine going again so I figured they can't mess up a iron jeep head but boy I was wrong they ruined 2 heads luckily I have a large stash of parts but one of the heads was a really nice casting I was pretty upset not only was the valve job horrible and the head still dirty and full of carbon they crashed their machine into the thermostat gasket surface I don't even know how you do that then they said they couldn't fix it because it won't fit in their machine but I tried explaining you can't fix that if you mill it flat again I'd have to run a spacer to get clearance back and it's not how i do things. Then the other head was just so bad after they were done I scrapped it and learned my lesson it's kinda like when I have McDonald's every 6 months to a year the fries are good but I get a gut ache and realize why I dont go again. I used to be able to use local places and get work done and assemble an engine myself but I just can't get the work done locally anymore so I have other ways of getting things done I've cleaned up heads and lapped valves by hand and done valve seals or I know a couple places across the country I can mail stuff too. Don't even get me started on transmissions, when I started out I could get reliable rebuilt transmissions sometimes I'd find problems but not like you do today. Even those real expensive purple transmissions I've installed for people in dodge trucks and found problems like really dumb problems and serious problems. I started having to do repairs myself and I learned over the years with a lot of things to never give up the core until you know that your new part is good that has saved me when I end up just doing the rebuild it's much easier for me to take apart a core and rebuild it myself than to take apart a rebuilt transmission and try to fix someone else's screw up. But a few years ago I met an awesome transmission guy who works out of a little shop on his property he's highly knowledgeable and has become my friend. I love bringing him stuff and he lets me work with him on my stuff when I want something custom or I have an idea and he lets me do carry outs he's one of those guys that just spews knowledge. I love meeting and learning things from guys who are so good at what they do, and he understands how hard it is to get good parts and he is like me with his part sourcing so I trust him to find me stuff or if he says a used original would be better than new.
I have a couple places I can work with through the mail I also have some friends that help me a little but I can't really do certain things on customer cars anymore in a reasonable amount of time because of the unreliable machine work and I'm not willing to half ass anything I want to make things better. One of my Hobby's other than jeeps is vintage dirt bikes and I found a guy locally who builds race engines for boats I'm not familiar with the boats or what he does exactly like what race team or where they race but I think he says they are mercury and he says they are 100k dollar engines the boats are really cool but he has a private shop and I have him do my bike stuff like crank rebuilding and some cylinder work I've also brought him my jet ski stuff. I also have another friend who has a mill in his garage and he does some stuff for me every now and then. But all that being said I can't just Google a machine shop and bring stuff there because of the high risk of things going wrong especially when it's a rare part I work with some very rare parts sometimes.
I can think of a few places that have gone out of business over the years that I did good business with. One thing I'm sure other mechanics are familiar with is how horrible reman alternators and starters can be I think O'Reilly is the worst offender. I won't install an alternator or starter in a vehicle anymore unless I source it. I found a place called DC power they make high quality alternators even with fancy billet case options thats what I run in my Jeep. But why I mention this is we used to have a wrecking yard somewhat locally and they would rebuild alternators and starters and even do custom upgrades like higher output and this was built with new parts they just happened to be a wrecking yard too. I used them a hand full of times and I had a friend who used them a bunch but I really wish they were still around it was really cheap too like stupid cheap. But I'd love to be able to use someone like that again but there's just not a demand anymore to repair that stuff.
Sometimes for no reason at all really engines will fail. Some 6.7 power strokes are perfect and they have no issues ever. Mine is a 2019 that has worked very hard its whole life at 155,000 miles and the only thing that went wrong was the hot side charge pipe. Everything else has been flawless.
Actually alot of 6.7 powerstrokes are flawless. I rarely hear bad things about them. I hear more bad about ram and gm
WOW! 6 bolt mains in that 6.7! Crazy
Imagine, the Cummins still only has a 2 bolt main AND it makes the same power with 2 less cylinders..... And I'm a Ford guy.
GREAT VIDEO GUYS
cummins is up to 400 hp powerstroke 450-475 and made to make more!! why you see the 6 bolt main and graphite block.
My 6.7 kingstroke make 700hp 1400ftlb torque
I tore a fb marketplace engine apart. It appeared it had been rebuilt but the rod caps were not marked so I marked all the caps, pulled the rod bearings out and they all looked pretty trashed, but cranked looked fine. After getting everything back from the machine shop, I assembled it and as soon as I torqued down the rod caps the engine was hard to turn. Tore it all back down and found that the previous “rebuilder” had mixed up all the rod caps, that was why the bearings were trashed. It took some time with a magnifying glass but I was able to match up the rods to the correct caps by lining up the machining marks. Put it all back together and it rotated just fine. I’m not sure how many miles they had on it after the rebuild but it had to have been really tight.
Good to know that super hero MEN are still out doing good in world while I’m having spine surgery on Memorial Day. Thank you Dave for producing excellent content and excellent product.
Best of luck on that surgery. I had mine a few weeks ago and it fixed me, thank God!
Best of luck to you with the spinal surgery. I had my neck surgery about 10 years ago and it's been great results.👍
The RSC cups with the post it notes in them for the bolts is genius. And, a plus when you are finished with it on Friday and Dave brings in the keg of Coors for you all employees you can all have an RSC cup slug of beer 🍻 on Dave. Of course you will need to rinse them out first and have Dave take you home in his minivan if you fill the RSCs up more than twice. Cheers 🍻 😊
Hi Dave, great video, thank you for wearing gloves when tearing down the motor. We love you and we need you. Keep up the good work.
I was a GM tech in 1988, making $11 and hour ,flat rate. It sucked, I quit turning wrenches in late 89 and went to driving truck. You have some good mechanics, Dave.
Another great video. I have a 2017 with the 6.7 Scorpion and although I'm on my 3rd upper oil pan leak, I love the truck. She pulls my toy hauler like a champ up the steep grades here in SoCal to the desert. Now, I only have 76K miles on her but I'm sure she'll go many more since I change my oil every 5K miles or every year. Which ever comes first. In my opinion, I think the Ford 6.7 Scorpion is the best of the newer desiels out there.
I love seeing the cab come off.
really great video, love seeing the thorough inspections after a failure
Watching Dave’s channel has removed all desire I had to own a diesel.
Every single engine ever produced has some kind of problems. Operator error or lack of maintenance is the number one problem with any engine! This 6.7 scorpion engine has been produced since 2011 and there are literally millions of them out on the road every single day. Being there are sooo many out there you are bound to see them come into a repair shop from time to time simply based on sheer volume that's out on the road. It is a really good engine other that the Bosch CP4 fuel pump and the emissions equipment bs on it DPF, EGR, SCR, etc that choke it & cause more problems that their worth. Taking them off dramatically improves longevity & fuel economy (20+mpg). Diesels are just like other engines, they need their maintenance done religiously. Do oil changes & fuel filters regularly at 5k mile intervals & problems don't happen. There are many diesel trucks with close to a million miles or even more out there on the road doing cross country hotshot deliveries daily. Diesel is the lifeblood of the country & the world. Everything gets moved by diesel power -trucks, ships, trains, etc.
@@tdotw77 Stripping an engine of outside systems only works if you live in a state that does not have emission testing.
I'll stick with my 2000 F-250 Lariat 7.3 4X4... She ain't a Beast but 24 years of doing the scheduled maintance and front hubs, Big Blue is still running Great... Heck she'll still be running after the 6.7's have been scrapped :)
Gotta do a full vid on a 6.0 powerstroke!
bro ive got to give respect to the camera guy or who ever had the idea to have this good of a camera and the editor not much editing but uploading at 2160p is nice
I find these videos so amazing
What quality of craftsmanship and integrity
Lifting bodies off frames as easy as opening a door. Would love to see a video of that process
Best to Dave and the Crew
John
Sounds good, will see if we can film that for ya👍
@@DavesAutoCenterCenterville Thank you sir
The first I saw that a few weeks ago, lifting the cab up and away I was thinking what a lot of work. But then when I thought about it, it is a lot less work compared to pulling the motor through the hood if that is even possible.
Worked at Toyota Fremont Ca for 20 yrs ; the frame comes along conveyer line upside down , they put the wheels , gas tank in goes to a lifter ,up , then rolls over , picked up by carrier , goes to another lifter , down into the front wheel alineer ,out around to a diff line , down , add more stuff , lower the engine & tranny in , then the bed, then the cab , lifted up goes round to new line , add the brake fluid, - wheels- emblems - set down on floor conveyor add doors , go through water test - add the underbody coating , paint protection plastic , drive to parking lot , then rattle check on wash board track, back to parking lot ready for transport
Dave, I have a question for you based off a couple videos you have done in the past about the Ford 6.7 engine, I too have completed a few rebuilds of the Ford 6.7 and have found the same issue when tearing down the motors you have with engine oil starvation causing the extreme main and cam bearing and roller wear which usually is the knocking or ticking sounds coming from the engines if they are still running. In one of your videos, it appeared to me that you most likely installed a High-Flow, Low Cracking Pressure Check Valve in the pickup tube to prevent the oil drain back hence allowing oil to always be at the oil pump to start pumping oil pressure quickly, in this video when you were showing the different oil pans at the 14-minute mark I did not see the check valve, was this just a pan you have not completed this on yet or intend not to use?
Do you install them on all the 6.7's you complete or did you say forget it and if this is what Ford did, and they designed this way, I am going to keep it that way?
I just started a new rebuild the other day and currently the engine is in the machine shop, I am going to TIG weld in a High-Flow, Low Cracking Pressure Check Valve in my pickup tube but was curious if this is something you do or sell now also? Love the video, on a side note my vocational school teacher was also named Dave, taught us to critically think and this was 35 years ago now and not to just replace parts much the same way it appears to me that you are teaching your team of people there to be, and the reason to your success.
These guys are motors surgeons💯😂😂😂
5:15 so how do the pieces of silicone get past an oil filter? Wouldn’t the pieces have to go through an oil filter to get to the piston squirter?
Did anyone else see all the Super Mario Brothers gold coins floating up and disappear the entire time they were working on the engine? 😀
Dave, Great comment on the documentation of all that you notice not working and systems being modified. In my word of maintaining multiple types of propulsion systems, I call it CYA, (Cover your assets). Also, having a tuner on a truck is not the best idea. Some portions of the tune will give you better mileage, some tune adjustments will create havoc on the engine or the transmission. Why risk the havoc, use the truck as it was intended within its intended capacities.
At 12 years old, I guarantee I would've done a better job on that engine. Whoever tried repairing that engine needs some folded newspaper disciplining and sent back to school.
Mercy that's alot of wrenching! Gentleman is skilled and earning that pay! Impressive sir.
10k oil change interval will kill those motor pretty quik i do mine every 5k
32 rocker arms, exhaust and intake reversed from the usual v8 setup. What a neat machine. It sounds like people seem to have lots of trouble with these engines but I can’t help but like the 6.7. Outside of 2 injectors, mine has been good so far.
The problem with the truck, BACKYARD MAN!🤞👎
that fuel filter is the absolute first thing anyone should do directly after purchasing any year 6.7 new or used a disaster prevention kit so when your cp4 pump grenades it doest cost you 10k to fix
I guarantee a piece of that excess silicone plugged the oil passage on that bearing causing it to fail
Not a Ford guy so not sure of the routing, but wouldn't the next stop in the oil system be the filter after the pump?
I think why crank grinders are rare is because only aftermarket shops will go the extra step! But also its performance folks doing that work and needing a 2 day turnaround is not feasible when they have 30 high dollar builds lined up!
Whole lotta hokiness... Love seeing it all taken care of 👌👌👌
For the record the piston cooling jet was likely damaged during reassembly by the 12 year old mechanic and when a PCJ breaks off on a 6.7 a piston failure is immanent. Also if the upper and lower rod or main bearings are transposed this will need to the overplate being overloaded. The lower mains and upper rod bearings are coated with a special material to handle the firing load and the lower aluminum bearings are supposed to be installed in the block and rod caps.
Silicone sister and her manager mister told me that you got what it takes . . .
Dave, I like your content and I love your professional, caring attitude … 😊
im sure glad Ford is helping you stay in business
These are good engines when the maintenance is done on time.
@@sprint2648 im sorry but been driving these fords for 30yrs plus their always alot of issues for us i own 2024 f350 7.
3 we switch to all gas now much better we do like the trucks all f350-f550
They miles we'll we got Obama motors and Biden dodge government been keeping them alive for ever now, still in dipers mater of fact😂😂
Hint why our military is full of junk been for years due to that!!
A burned blue engine bearing and melted Babbitt material with an intact crankshaft journal can result from a combination of factors:
1. **Oil Starvation**: Insufficient lubrication can cause excessive friction and heat. The bearing may suffer the most because it directly contacts the journal. The lack of oil prevents heat dissipation, leading to bearing overheating, discoloration, and Babbitt material melting.
2. **Bearing Misalignment**: If the bearing is not properly aligned, uneven load distribution can occur. This causes localized heating and damage, even if the crankshaft journal remains unaffected.
3. **Improper Bearing Clearance**: Incorrect bearing clearance can lead to insufficient oil film thickness, resulting in metal-to-metal contact and overheating of the bearing. The crankshaft journal may still appear good if it was not subjected to prolonged or severe contact.
4. **Contaminants**: Debris or contaminants in the oil can cause damage to the bearing surface while the crankshaft journal, being harder, remains relatively unscathed.
5. **Material Defects**: The bearing may have had material defects or manufacturing issues, making it more susceptible to failure under heat and load.
6. **Heat Transfer**: The bearing can experience higher localized temperatures due to friction, leading to discoloration and Babbitt melting, while the crankshaft journal, being larger and better at dissipating heat, remains in good condition.
In summary, the bearing is more susceptible to damage from heat and friction due to its material and position, while the crankshaft journal, made from tougher material and better at dissipating heat, can remain unaffected even when bearing damage occurs.
Great video, as always.
I really enjoy your videos Dave, and I appreciate the work you do and the quality you deliver to your customers.
Another interesting video. Thanks, Dave.
Glad you enjoyed it
The clockspring could have spun when the cab was removed from the chassis. But i think yall are smarter than that, Ive had too many times ive fixed one thing and customers says that wasnt broken or that wasnt like that, So ive learned to go fully through someone's car before major repairs.
Dixie cups and 3M post-its is the cheat code!
Yep, super high tech system 😂
If he doesn’t want the correct tune would you still warranty the engine? I wouldn’t. 😉
Pretty sure Dave won’t warranty it unless everything goes back to stock.
