This is phenomenal. Whatever you charge people…is worth it. I have never seen a mechanic take this much interest in making solutions rather than making money off of common problems.

This is 1000 times better than the Saturday morning car shop shows I’d watch on basic tv as a kid! Thanks for your content!

This guy is elite on every level. From choice of topics, to insight and knowledge to delivery, persona, dynamism and charisma.

This channel and Dave's knowledge and interests in finding problems is absolutely mind blowing! This is my favorite channel on here because Dave knows his stuff!

This guy is a gem. This channel is going to explode. Great communication and super professional work and shop.

For over 50 years I've wondered why they didn't add an electric pre-oil pump.

It's rare to have such a brilliant mechanic or engine builder who is also an excellent communicator.

Dude definitely knows his stuff and presents it very well.

Lets give Dave more credit, hes just more than a mechanic for the normal people that don't understand. He is an engine rebuilder not an engine overhauler. Engine rebuilder is when you alter to new specifications which requires engineering knowledge that allows hims to explain it and make it sound easier to the public and to Overhaul is to bring it back to the original manufacturer specifications what your original mechanic does with less knowledge and goes by the manual. People..... There is a difference 🙌

Watching these videos makes me wish I had stuck with this industry in my late teens, early 20s. The need for this level of work is at an all time high and you’ll never be short of work.

Dave keep these videos coming brother! This channel is gonna be big in the near future. Theres tons of valuable info for us gearheads

Dave people like you are few and far between these days!! Keep up the great work and awesome videos 👍

I've built 2 engines, 1 car 1 motorcycle, the attention to detail always impresses me. Well done.

Ive been working on Powerstrokes for a little over a year mainly 6.7s and honestly RARELY come across the symptoms you mentioned. Many oil changes turbos upper oil pans and full engine reseals, I have NEVER first off heard any clacking noises after an oil change or seen a 6.7 lifter explode sending needle bearings through the motor like the 6.0s. The early 11- mid 12 years the tappets in the lifters spun and fail but NEVER has ruined a camshaft, had one recently pushrod came off the rocker arm and was STILL running fine. Actual big reason is people LACK MAINTENANCE never have seen a 6.7 bottom end spun a bearing even with ccvs that internally go bad and suck/burn oil didn’t ruin an engine. Ive seen 300k 6.7s and work trucks for asphalt companies high idle times and rarely have issues. If there is anyone to blame for engine failures its owners who dont keep up with maintenance schedules, repairs and abuse them with tunners so cant blame engineers if they’re not intended be taken care of and for proper use.

He explains things well , gets to the point , clearly loves it , always training the young guys . What a great shop To be in if your young and up and coming

Always learning Dave, just like you said “ Be curious, just like a child. “ Brilliant. Thanks as always.

This guy is awesome. I have never heard anyone talk about auto machining and fixing problems like he does. He's a walking, talking automotive genius. Engineers today seem to make everything so complicated, and you look at how to simplify their screwups.

I love to see how Dave pays homage to other guys.

Wow Dave you are truly an old school mechanic with passion. You remind me of a guy that taught me how to rebuild my first Chevy 250 in-line six engine 42 years ago. I used plastic gauge on all of the bearings to get perfect oil clearance . Bored it 30 over . New pistons/rings added a quart of marvel, mystery oil to my regular oil. The engine out lasted the truck. As you know 1969 Chevy pickups had a rust problem. I enjoy your channel and you passion to make engines better. Mr Fowler

This guy is a true professional. No BS and is asking all of the correct questions followed by coming up with a proven way to remedy problems created by Engineer Johnny. Looking forward to the second part of this video and see what his findings are as well as his thoughts on how to correct the problem. I’ve read a lot of horror stories on catastrophic engine failures where owners are getting screwed over by Ford. Not something you want to find out after spending $85,000 plus on a new truck. Hence the reason I’ll never sell my 2002 7.3 PS.

This content is precious.i could listen to Dave for hours Thank you Bring it up more videos, we will watch!

This is the essence of all work, do it better and better, until perfection without losing yourself along the way. Congratulations

Dave....thank you for taking the time and teaching us all of this valuable information.

Not to many shops admit that they dropped something into the motor. You get big props from me bro.

I have a friend who has had two 6.7's (a 2013 and a 2020) he has put close to a half million miles on them - never had any bearing problems, cam problems or turbo replacements. The most troublesome part on these is the Radiator.

This is one of the best channels out there!!

Total agreement Dave, you are spot-on. I was taught many years ago that needle bearings are good for intermittent loads & LOW, (NOT HIGH) RPMS. (ie; The trunnion/output shaft of an old-style steering gear. Shock loads, mininal RPMs & frequent directional changes) I never imagined them holding-up inside a lifter, way back when. Bucket-shimmed valves are great, (used in high-revving bikes), but are a pain to adjust. Luckily they don't need frequent adjustment if done right. Keep up The Great Work Brother🙏 (Not just great vehicle repair videos)👍

With the new engineers it seems that they have lost their common sense of basic principles which this is the end result. Glad you were able to identify and fix this problem. Awesome work!

I absolutely love your honest professionalism!

I’ve been a diesel mechanic for fourty years and yes, oil pressure buildup has always been an issue. In the 80’s Leyland fitted secondary electric oil pumps to boost supply at startup. I remember a Cummins circular in the 90’s pointing out that most engine wear occurs at startup and very worst when oil is changed, we always pre filled the filters before fitting for this reason.

Wow is all I can say I really wish all auto and engine shops cared this much. You guys are truly professional. Very impressive

Wow that is a lot of passage dry. I knew there was some, but never thought it was that much. I have heard many say you don't have to fill the filters anymore, after this I really know better. I always have out of pure habit, I'm old school. Just like I always change the thermostat when I change a water pump. Some vehicles that is major. I will be looking for how you fix this problem. Do not cut yourself short saying someone is smarter than you. You are a genius as far as I'm concerned.

I got a '16 F350 in 2 yrs ago. I was told the engine locked up. Couldn't turn it over at all. The owner didn't want to buy a new engine, so the hunt for a good used one was on the way by him. After 2 yrs of it sitting, the owner told me to pull the engine. When I pulled the starter and found the starter gear was sideways against the flex plate jammed in place. All the sudden the engine turned easily. I put a new starter and batteries on, the engine started right up. It ran for 2 weeks. Then the owner decided to put it back in service. So they put a 20k lb trailer on it and off down the road. 5 miles later the engine quit. Hauled it back, found metal in the fuel system/tank. Did a few diag on it and concluded the injectors were stuck open from metal being in them. Dropped the tank to clean it, put a whole new fuel system in, the whole works. Put an s&s bypass kit on also. Thousands of dollars later, go to start it, won't start. Acting like it's hydrolocking. Looked at it a few days, new starter, batteries, etc. Fuel pressure good, everything looked fine. Pulled the oil filter and cut it open. Found a ton a metal flake in it. I'm like what the****. Instantly figured a bearing is seized or grabbing the crank mimicking the hydrolocking. Now that I seen your video, I'm wondering if the dry starts caused bearing failure. I have no clue what caused everything as the original thought was the engine was locked up two yrs ago. I just can't see how if it was a bearing back then, how'd it unlock and run for two weeks with no noise or indication of anything being wrong. I'm assuming the starter messed up, jammed it, then after sitting two yrs the cp4 came apart and sent metal through the system and caused it to hydrolock and somehow jammed a bearing up enough to break it or something. Or maybe zero oil upon start-up ruined it pretty quickly. Either way, now I'm in search of another engine again. Ford wants $19k for a complete engine that is on backorder currently. Their reman is $8k or so but they said it was an updated engine and several things had to be changed to make it work on the '16. We have a brand new complete fuel system, so I didn't want to spend $19k on the complete one. And none of the local diesel machine shops in okc wants to mess with it. They'll machine the parts individually but none will do a complete teardown/reassembly. Also they all told me they're at least 6 months out. Just roadblocks every direction. The owner doesn't want to trust a salvage engine, which I don't blame him.

You are doing a wonderful job, gentlemen. It's nice to watch you at work. Greetings from Poland🇵🇱🇵🇱🇵🇱 👍👍👍👍

Sir I really want to thank you for the time you take out of your day to show these things. Please keep making them.

Very interesting video! You did a great job laying out the facts. I was shocked at such a circuitous path the oil must travel. As over engineered as the engine is with excessive parts, I’m surprised they didn’t add a pre-oiler pump to come on prior to the engine starting?

I learn so much from the man. Hes so knowledgeable

i work for the dealer and customers are very happy with their 6.7 strong powerful and dont have real major problems the oil will sludge if you dont change it can cause issues

Love the Steve morris shoutout. Guy is insanely bright when it comes to building an engine.

Dave, I always tried to explain the difference between an engine builder and an engine assembler - most people don't get it, of the ones that do some would stop by, or call; "Mike, that thing uses so much less fuel, has more power, is smoother and quieter than it's ever been!" or, "I went to the track last weekend, the cars that used to run with me or just get away from me are Way back in my rear view!" All the time in reworking poor designs, checking everything, doing it right meant more than the money when I heard those. When you love what you do. Some people understand, most don't Nicely done, Dave

We worked with RMC to develop the first ETS for our factory. We even developed the fixturing and block offs for the 6.7s. Prototype is still testing engines everyday. Good guys to work with.

Hi Dave!! Just wanna say your KZfaq channel is such a blessing for me who is shopping for a good truck and watching your video is teaching me a lot. I don't know much about cars but watching your video helps me and many others on what to look for when purchasing a used truck. Brand new trucks these days are way too expensive soo going the used route is the only way for me.....and knowing what I know because of you helps me be confident on what to look out for. I wish your shop was closer to me. Glad to see a honest mechanic having soo much success. Thanks Dave!!!

Sounds like a good candidate for a dry sump system with an electric pre-lube.

This channel is gonna turn into a wealth of knowledge and earn Dave a lot of money...I cant wait to see all the new toys he buys for the shop! Awesome channel!

2011 6.7 owner here! Very curious to see your results! I have 300 thousand on the clock and no major issues yet🤞I really appreciate the content it’s very educational. Weirdly enough I hope to have to rebuild mine one day, I must be sick haha

Wow Dave. Real interesting. At least someone is thinking about the issues. And yes I’ve been watching Steve Morris as well. Very talented. I watched the Wagon run yesterday and I was blown away. Thanks for your knowledge as well 🤩

DAVE , I admire your knowledge, skill & honesty . I am in Australia , I have a 1968 HOLDEN KINGSWOOD HK with a 186 Engine . Very humble , I know , but they raced these 186 Cubic Inch Engines with Triple Carbs , Headers & they raced & beat Ford 351 CI V8's at the Bathurst 500 . I would love you to be able to rebuild my engine to get all the appropriate horse power I could . Wonderful information . Thank you Dave - ROBBIE.

Very interesting to just show the oil pathways of this engine. I'd love to see you do a Ford 300 inline 6.

As a retired certified CAT&CUMMINGS knuckle buster what you just showed is why they need to take the BOX OF CRAYOLA AWAY FROM THE DESIGNING ENGINEERS!!! For ever turn that oil takes causes RESISTANT!!! EXCELLENT VIDEO that shows start up problems then add in the RESISTANT and you have the RECIPE FOR FAILURE!!! The old 7.3 POWER STROKE which was a INTERNATIONAL ENGINE was far SUPERIOR!!!

My Aston Martin DB9 has a function that eliminates this issue. When cold starting, after being left for a long period, the starting procedure is as follows. Floor the accelerator (this prevents the engine from firing) and then crank the engine until the oil pressure light goes out. I do this in three five second bursts in order to not overheat the starter motor. Once the oil pressure light goes out release the accelerator and start the engine as normal, cue glorious V12 exhaust note. Personally, I love the ritual of this start procedure and the knowledge that I am looking after my engine as best I can. Great engineering Aston. Thanks for the video as per usual it expanded my knowledge.

I like how you do testing in the follow-up video to prove your points.

The fix IMHO is a pre oiler pre start. A small pump pulling from the oil pan, depositing pre oil filter that pushes approx 20 psi 30 sec before crank.

Sir thanks for the information. When I first heard your problem I thought it was cavitation in the system but couldn’t figure where you would get that from. Now that you explained the route the oil takes I do now. Multiple 90 bends. The other things is the pick up pipe if where the pipe joins the block if it’s above the oil level that seal better be perfect or it will draw past and also that length it pick up tube may suck the strainer down to the sump causing starvation and or upset that seal in the pipe That’s my take on it. Look forward to what you are doing on this project so subscribe so not miss it. Thanks Bob.

You've got my business! I have a 2012 F350 6.7 Powerstroke. 364,000 original well maintained miles.

I love shops like yours, which are so few and far between

I ran a brand new Cat D7 dozer that wouldn't start till the PreOiler had the oil pressure up to full, than it would start on it's own after that. Took about a minute.

I remember the accessory "12v oil pumps" or "pre-lubers" that was popular in 80's. That may be a fix for this!

Wow wished I lived in Utah would love to work for this guy . He's a genius

Love this guy ! Passionate about his job ! And always look to improve an engine and make it better!

Appreciate you being humble about past mistakes ie the little nut or something that went into a new motor. Accidents happen and learning from them is part of the process, I know that myself. It's partly why I get so mad when guys at the shop start cleaning their stall with the compressed air nozzle. Blowing all that crap on the floor with the air nozzle can make its way upward and into an engine (intake or whatever). Also it's easier to just get a broom anyways.

I've worked professionally in the automotive industry for 18 years, and my very first fulltime job out of high school was at Jiffy Lube. Now, everyone is as good as their training, and the environment you "grow up" in a C level tech. Every diesel engine oil change I did I always primed the oil filter, and I also primed gas engines with large oil filters. Not every quick Lube facility is garbage, it's as good as its owners and management

I'm in the UK, and even though the engines are completely different here, I find this channel very interesting and informative and can take away some good advice especially the importance of regular oil changes thank you Dave

Wow! Where my Kia Soul is parked I get a lotta tree shit blowing into that catch all above the engine so it could very well clog up those drains! Now my vehicle is new so no damage yet but I need to check that shit EVERY TIME that I fill up! His knowledge doesn't necessarily only reflect on the specific vehicle he may be discussing. The subject could be applied to many vehicles. This is a perfect example. Thank you, Dave...

Dave: the dad mechanic for those of us who didnt have one !

The 6.7L powerstroke engines DO NOT have "bad Engineering". This engine has the best modern design from any other manufacturer out there. This is from LACK OF MAINTENANCE and nothing else. The oil drain back problem is OVER EXAGGERATED on the internet, most oil filters have anti drain back values, this is why the engine takes 15 quarts of oil because of all those oil passages, the tolerances are very small in the engine. Those oil passages stay full of oil. Pumping air? How is air getting into the oiling system?

friend, thank you very much for helping us improve as mechanics

What an excellent observation Dave made with this lubrication system!!! The engines that were/are reliable do NOT have this much VOLUME in the low pressure (suction) side of the system BEFORE it even gets to the pump!!!! And the routing of the lube system on the High pressure side of the system is very convoluted and indirect to the places that the oil needs to go to lubricate the high wear / high pressure areas like bearings and the valve-trane... Ford, has taken a very bad turn with their current equipment... So much of what Ford learned from the past, has seemed to have been lost since the Phoenominal 460's, 430's, 429's , 428's, 427 side-oiler , 390's, 351 Windsor , 351 Cleveland, The Cosworth v-8's, the Pinto engines, all of their inline 6 engines.... The list of sucessful Engines that Ford has created and manufactured are impressive and numerous... Unfortunately, several of the Power-Stroke diesels appear to have completely missed the mark, that Ford established in their past....Some of the Ford diesels (like the 6.0 V-8's) had a large amount of problems that should have been recognized & taken care of BEFORE they went into production... There are aftermarket companies that 'Bullet-Proof' those problematic engines... And apparently, this work was not subsidized by Ford, who originally manufactured these problematic engines... The customers who purchased these vehicles had to cough-up the $5k-$6.5k pricetag of doing this type of work (2016 pricing).... There should have been recalls on all of the 6.0 Litre diesel engines, but somehow, Ford was able to get away with that very poor design... Nobody who manufactures vehicles is perfect... Mistakes can be made, especially with new designs... But they should take the responsibility of covering for their mistakes, by performing recalls. Ford offered No such help for their customers... Ford used to stand for : First On Race Day... Now it stands for : Ford Offers (Their) Recall Disapproval...

Great stuff. Can’t wait for the following videos. Since you’ve been doing this so long, what is/was the BEST built engine?

In another life I am sure Dave would of been an outstanding Doctor 👨‍⚕️

First thought Running with air instead of oil .. You prooved my thought...2 possible solutions 1 during starting no fuel for x revolutions 2 electrical oil pump with pressure contact so you can asume your oil is where it needs to be before starting the engine.... Excited for part 2

Just found your channel last week tons of information really appreciate you.

This is really good content, I’d trust your work, I can just tell, curious what kind of oil do you personally like? We have a fleet of 6.7s and run shell 5w40 syn & haven’t ran into any issues. High engine hours 14k…but they never see cold starts because they are constantly running and garaged..probably why they have lasted so long

The real question is why the hell is every vehicle and engine so overly complicated now days. I sold all my new stuff about 3 years ago. Have all stuff around 2001. That is the peak of simplicity and creature comforts to me. I can open the hood, fix things, understand things and trouble shoot things easily!

Always very interesting watching your short videos. You definitely take pride in your work. Keep them videos coming.

Dave, This is next level! Presenting data like this is invaluable to us techs. Amazing work my freind, I cant wait to come check out those shops. I can't get enough of these videos. Please, with sugar on top.... we need more!!! Keep these coming 👍

Found this channel couple weeks ago. No BS, no clickbait, no gimmicks. Love it.

I'm thinking my old 7.3 is worth hanging on to

Really Good infomercial for attracting new shop customers. Few shops have the equipment &/or experience to do right by your broken diesel !

I have a Ford 6.8L V10 gasser in a 1997 Class C motorhome. Whenever I put the vehicle into storage, I remove the fuel pump fuse so the next time i start the engine, it will crank without fuel. When starting the next time, I crank the engine for about 45 seconds and figure that's enough time to get the crankshaft, cylinders & cams lubricated before replacing the fuel pump fuse and starting the engine. And you bet, whenever I change the oil (every 3500 mi), I fill the NAPA gold (Wix) oil filter with oil. Engine has 80K miles on it, and burns zero oil. Thank you Dave - this video confirms my '78 BSME intuition that I haven't been wasting my time!

I would love to be an apprentice for you guys! I’d soak up as much knowledge as I possibly could.

Hola señor Dave…I will keep checking for the part.2 of this video…it was very informative and educational I hope engines are built better cause we need to have a reliable vehicle for transportation on daily basis…Saludos!!!👋😃👋

I am a motorcycle mechanic and I have learned yet another thing about engines and engineering.Awesome!!!17 years in the trade and still learning

Sounds really interesting I love your enthusiasm, I can't wait for the next video instalment.

Ford calls that rattle “A typewriter sound” and there a SSM for it and Ford calls it “Normal Operation”😂

It would be interesting to see how much of the old oil never comes out with an oil change. Kinda like not being able to drain a torque converter on an automatic transmission when you service it...

Much respect for you Sir for being so passionate. All the way from South Africa

Ngl I’ve been addicted of the content of this channel. Keep it up 👍 real question I recently started changing the oil myself. Does this 9:18 tip about the oif filter being filled up with oil goes for all oil filters on 4 cyl engines?

Add an external oil pump for pre luring every engine b4 start up. Your gray hair is working! Takes a lot of brain damage to get it. You have my respect.

This why I put arch oil heat modifier along with Lucas oil treatment so that oil sticks to internal engine part. I love the information in this video

Amazing amount of work. Just an incredible video.

My 94 Gmc 1/2 ton 350 had a knock on start up from day one. The service bulletin said replace rod & main bearings or use an oil filter with a check valve. Still running at 188,900

The best way to fix this problem is give the Ford to someone you don't like and buy a Chevrolet 😂😂

Dave, I love your videos. I live in Ogden, Ut and find your shop to be incredible. Keep it up!

I bought my 2002 Dodge Cummins diesel new I've always done my own oil changes one day several years ago I was changing the oil in my truck I'd already drained it an pulled the oil filter when my brother in law came up while i was pre filling my oil filter he laughed at me and said it was a waste of time well 326560 miles later my 5.9 is still purring along strong no major work ever done to the engine ! I'm a firm believer that when you can you prefill your oil filter and you confirmed that right here in this video ! Thanks Dave ! I'm not the smartest nut on the block but I knew this much !

The 6.7 has issues this is not one of them. Im on all the forums and nobody has issues like this. Its probably the fleet vehicles that never change their oil

Dave is the reason I will be having his shop rebuild both of my trucks engines when they have need. They are both over 120k miles now & still run very well. The rest of the running chassis and body are perfect. The rebuilds, when I determine necessary, will be well worth the cost as opposed to buying a new truck.

Dave, I just want to say congratulations and good Luck on your new adventure with discovery channel. Since the first video that I ever watched of you. I knew that there was something special about you. You had the right look the right voice and Outstanding knowledge Of engines Along with constantly trying to make every engine better Then it can ever be. Keep up that great work and I know you will be successful with Discovery Channel. I can't wait to see You and your team Doing what you Guys do best. GOOD LUCK

Love this level of detail. Thanks for the info.

You got a great show I am no mechanic but what you do is amazing with motors.

At approximately 14:30 mark Dave was demonstrating needle bearing failure and how high performance engines are built with a bronze bushing. I have never built any engine but as soon as he talked about this bronze bushing the light came on. I used to work in a maintenance shop for heavy equipment at a mine. The "bearing" for the pivot shaft on CAT dozers is a bronze bushing.
