Awesome video! Mark is the guru and has taught me so much! Surface finish is my favorite topic because it heavily influences oil performance. Thanks for this incredible lesson. I even picked up a new nugget!
That why we love you and Dave because you keep learning even though you have so much knowledge! Thank you
Marks okay but tri dial bore gauges and mitutoyo surface testers been around 25 years and Dave should know this. Everything is accessible to all of us this is kinda mis information. We hold .001 tolerance and specific RA surface finish on 16” x 14’ cylinders all day long.
@@sxslayerxsWho is we?
Perfect TH-cam screen name Lake!
You're not too bad yourself Lake! 😅👌🏼👍🏼👍🏼
It's great to listen to someone with a PhD in something that actually matters
There are some PhDs that can communicate the material so that virtually anyone can understand the topic. Dave’s crew are pretty sharp too.
This is without a doubt the best channel on TH-cam right now. The amount of knowledge you can get from this channel is amazing
Yep… and it’s the deep knowledge that has traditionally been kept for only the ‘chosen few’ (metaphorically)
I’ve been wrenching on cars, motorcycles, small engine stuff mowers etc, for 50 years.
Back in those days it was difficult to get a hold of books, let alone those that could interpret the data to be able to convey it in layman’s terms.
Everything I learned was at a basic practical level, the theory side was always a ‘mystery’ lol😅
It's helped my understanding of engines, how the components work, and what happens with lack of proper maintenance
Appreciate that
agreed
I agree with you 💯
What a absolute privilege to include us in that conversation, thank you.
Retired Quality Manager here. I haven't had as much fun watching a master explain how to interpret complex data visually since I first discovered the Western Electric Statistical Quality Control Handbook many years ago. Seriously.
I’ve been fixing cars for 15 years now and this channel has expanded my knowledge exponentially. I love the guest appearances from legitimate automotive scientists. Thank you for the new knowledge!
Great to hear!
The advances in technology are astounding! !'m 65. When I got out of high school the family business was earth moving. The old Cat dozers would develop a glaze on the cylinders and just guzzle motor oil! We use to use "cylinder hone in a can" to stop the oil consumption! Remove the air filter, crank it up to the governor, toss a handful of Bon-Ami right down the intake let it run on the governor for 5 - 10 minutes, shut it down and change the oil! Fixed! LOL! It would come back and need a retreatment every couple years but they'd still run for a long, long time!
It sounds like it worked. But Something Dave's shop would probably not do . 58 here and the new technology is amazing
@@Kevin-ti3rz It did work. LOL! I believe the cause was 1. the oils back then were not as good as they are now and 2. the old Cat motors made enough HP to push earth at low RPM's. Other machines would be in 1st gear and full throttle trying to keep up to the Cats. When it didn't work it was time for a real rebuild!
They did that on the old British bikes back in the day too.
Hadn't heard the Bon Ami treatment mentioned in years from the long gone old heads.
Lol Bob-Ami? The natural powered cleanser? Haha and that would fix the glazed bores?
He is exactly right Dave! We could watch "Surgery" in your shop all day long! Nothing to it. I love watching and following along when i can on your tear down procedures for the foriegn cars you see, the trucks exc, its truly a wonderful thing what you do at the shop, thats what stands out to me as CUSTOMER SERVICE! Not only do you show them, but you explain to their best understanding and its awesome to see! Keep em coming 💪
Keep on wrenchin!
You guys are the biggest automotive nerds I’ve ever seen and I am here for it! 🤓
WOW! Fantastic! Way above my head BUT also enlightening to show me what I don't know. Super smart educated guy that has the ability AND desire to talk with AND share his knowledge. Great episode!!!
Glad it was helpful!
As a software engineer for more than 25 years, I love understanding mechanical engineering,. We are closer than you think.
Fully agree
The science blows my mind.
It's what is making cars faster and better. Technically, they drive around in circles, but the science behind it is the key!
Very scientific, bore / hone finish taken to another level. Excellent presentation, thanks Dave.
Many thanks!
Dave has a PHD in automotive MAGIC!! 🙌🏻🙌🏻🙌🏻
It's really enjoyable to watch as someone newer into the automotive field. Wading through all the "bro-science" of people building engines is a lot easier with people like this talking about the reality and not what Joe's dad did 40 years ago that "worked for him".
Everything comes down to something touching samething, let’s hug!
That was great. I love the technical stuff. Of course your tear downs are fun to watch. Diagnosis is good ..... well heck the whole show is great.
Dave, I've only recently stumbled upon your channel and your content is awesome and addictive ...
Thanks all the way from beautiful Tasmania Australia 🦘🌏🇦🇺❤️
Awesome, thank you!
Great Video !
1) What i'm seeing what is required here is the " Quality of the Surface Hones Material ( ability to not break down ) & the Materials ability to Maintain a Quality Cutting surface.
Crappy Hone = Crappy cut.
2) Start Ordering Hones from Different Suppliers.
3) Do a Cut with each different Hone Manufacturer & Log how many cuts each different hone provides.
4) also A Hone Facing tool is going to change things also.
5) Also I'm Sure You are Filtering Your Cutting / Cooling Fluid. Monitor Cooling Fluid Temperature & TDS Count. maybe thier is work there that needs to be done.
6) Maintain a Constant Temperature of Cooling Fluid. Refrigeration unit or Heating unit to Maintain Consistency.
7) Filter Your Cooling Fluid Down to 5 Microns. Check Your Filtration.
Oh that makes sense!!! Once again we are blessed with top tier automotive knowledge
Without any doubt whatsoever, this has been one very very interesting episode to watch. I spent my whole career, 50 plus years in the metal finishing industry, mainly doing Hard Chromium plating for many thousands of diffrent applications. It was nearly always deposited on a pre ground finish. Over the years I learned that the courseness of the pre-grind before plating can have a critical effect on the durability of the finished ground chrome plated surface when it gets put to use.
I absolutely love these deep dive videos that you do Dave, please "keep on keeping on" in your quest to be the very best at what you do. I really appreciate the way you share you hard earned knowledge with us, but also respect your constant desire to learn and know even more. I have only been following you channel for a few months now, but it has become real favourite to follow.
Many thanks
David in the UK.
I learned something, thanks Dave, Mark and team!
Glad you enjoyed it
just one more day of learning something new, great video
Awesome! Thank you!
ALWAYS Great info from these guys. So incredible to see "The Boss" and his crew of professionals learning & validating what they already know & Do. Pure Excellence.
Our pleasure!
Things have changed since I use to work on cars back in the 60s and 70s just a little bit 😂😂😂❤❤❤ love this channel
Thank you!
I am sooooo happy I discovered your channel. I've been an aircraft mechanic for 35yrs, I remember tearing down old 9 cylinder radials many years ago....Love your content....I could listen to you all day. Love it .
Welcome aboard!
Very interesting, I'm a retired engineer from a balancing company for crankshafts and tire&wheel assemblies, the peaks and valleys discussion is exactly what we dealt with the center bore with all wheels and tooling correctly for each application.
Best explanation I have seen of what happens with correct plateau honing. Thank you for posting this.
Excellent lesson in surface preparation.
I'm glad I just attended the physics class at Daves Centre. I have learnt so much in a short time.As a diesel mechanic, now I get to know what it means to get that precision mark.
I understand the very basics of this conversation but it’s cool to see the in depth stuff behind this. Not an engine rebuild or at the very least not to this level never had the need but know the need for guys like this. Love a craftsman and master of his trade so cool and interesting to see. Love these kind of videos
You always have great stuff on your videos but to see some of the guests that you have been bringing on is truly awesome. These guys like Mark and Lake are not just good at what they do, these are the guys that wrote the book, literally, in their respective fields. I'm completely impressed! Thank you for the great content and for teaching us along the way! 👌🏼👍🏼
I appreciate that!
Greatly appreciate the video Dave!! Very informative and I'm looking forward to my next rebuild!!
Another great Video Dave, with experts in the industry . Thank you again Dave . I would Love to see a video with you and Gale banks talking motors and Turbos
I would love that as well!!
Great stuff. Two great men.
Thoroughly informative. Earlier this year finished rebuilding a diesel engine taking in David Visards presentations about engine performance. Now understand how a plateau hone is achieved. Dave I am glad to know there are bosses like you out there. Your team are privileged!!!
Hola 👋 señor Dave!!!! You are a workaholic making videos on a Saturday and I don’t have an idea of what this video is about but once I start watching it and hearing what you guys are talking about I just enjoy watching that’s why I always say that this is a great video for your tv show series 😊
As soon as you started your comment with Hola senor Dave I started reading your comment with a Spanish accent. Funny how the mind works .
@@190055joe ha ha that’s great that means you’re a potential bilingual you help will be needed in hospitals, elementary schools etc it’s a pleasure to help others…You keep up the great work…Saludos!!!👋😃👋 Y’all have a great weekend!!!!
Another level. Sounds like that’s where we’re going. Good video
I am speechless, thank you for taking the time to make all these informative videos and please keep on doing so
Fascinating stuff! I bet the future of engines will be an electrified oil running through Tesla valves that are microscopically bored into the cylinder walls.
Great content! Thanks so much for sharing!
Your perspective on your operators and mechanics is the best. My last employer didn't understand that at all, everyone loved me as the production supervisor because I was the only one in the chain that knew that and respected everyone appropriately. The owners didn't like that at all though, which basically drove me out. I don't see that business lasting more than another year or two.
This was such an amazing video. Thank you. Videos like this make me miss automotive
I suppose as a shop owner you can periodically send your techs out for recertification and updates on training( perdiem and motels on a business trip) or...or if you are fortunate enough to have a PhD guy come to your shop for a session. What a blessing of an opportunity.
Its amazing the things you guys do to motors. You all go above and beyond to get out a great product. If time permitted and as your channel grows maybe you could at some point do a give away motor rebuild to a viewer.
Never knew the proper procedure to hone a cylinder wall now I know. Great lesson
Lake Speed has videos on the importance of doing break in maintenance to remove the wear metals .
Best discussion on plateau honing EVER!
Here's the dutch guy again. Never been good in science, but love it when people talk so passioned about it. Didn't know there is so much "science" behind rebuilding an engine. Dave,,,,,,,,,,,,,,,,,,,,,love your video's.
Glad you enjoyed it!
Simply amazing. I’m so intrigued with everything including Lake Speed Jr. now, let do all three of you 🙏
In the 1960s blocks came back from machine shops just fresh off the boring bar and they were far more primitive than today. I saw the first automated with cutting oil flow cylinder bore honing machine that we are familiar with today around 1970 . It was transformatory in piston/bore life. Along with modern synthetic oil after 100,000 miles cross hatching is still visible progress has been amazing .
ive heard of a car being torn apart, every internal part measured and at 150k miles everything still measured within tolerance for NEW parts. not just good, but literally good as new. actually impressive
My new favorite channel! Great work Dave!
Wow, thanks!
❤❤❤ We Need More Dave , Super Thirsty for knowledge from awesome people. Plz keep it coming. Love this wisdom, knowledge, experience.
You got it!
Hugs are so important Dave, Mark. I had a family practice office for 43 years and my receptionist was a great hugger. I was too. But there were times when I could have stayed home and my receptionists hugs would have cured much of my patients ills that day. She left one surgical practice later when told she couldn’t hug patients when she saw they needed one.
Love how much Dave’s auto showcases the intersection of science and practical application.
WHOA ! WOW ! Y'all just provided a mind=boggling amount of information about surface finishing for all your viewers. Thanks, Dave, and keep up the quest to improve your products.
Amazing education for students,thank you for sharing. Mark and Dave ‘s program!
That was terrific.
Thank you for sharing.
So 90 % is an ideal ratio of plateu to valley, and then you've got depth of valleys from your initial coarse hone, and valleys per inch.
Before Mark started his own business, he worked with me and my group to solve some oil consumption and emissions problems. His knowledge basically saved the bacon regarding our engine program. We were all sad when he left our company to start his own. The entire engine industry has benefited from his participation!!
Pareto principle strikes again. 80% of your results come from 20% of your efforts. Just about anyone can put that 20% in, but guys like you who put that effort in is sure impressive!
Amazing science to absorb and comprehend.
I only understood a fraction of what was said, but understood underlying principle being put across there.
That man is leading the engineers into new ways of thinking and looking at surfaces… fascinating.
This is the precision machining that automotive engineers dream of…. And it’s within our reach, but the machines are expensive. Always a cost to reach the next level I guess.
I was watching mechanic channels for a while but this one is hands down by far the best and really good. Hello from
Chicago .
I think Dave could have a 2nd TH-cam channel just on engine rebuilding. Love this stuff!!!
I’m barely qualified to change my own oil. Certainly never listened to discussions or been involved in engine work but I love your guys information. Super cool.
Just amazing. I see people talking about these parameters but have to wonder how many know how to dig deep like this.
SO COOL to come along for the ride of what feels like the cutting edge of this industry with the legends!
The only master class I've ever stayed awake thru the entire lecture
I had intended to just listen to the discussion of this episode, but had to sit down and pay attention, and I definitely did learn some things! Regarding the roundness of bores and how that translates to a dial bore gage, I prefer to use a three-point gage (three points, 120 degrees apart, such as a Mitutoyo Intrimik, etc.) as it tends to show problems with roundness better than a two-point gage (one movable tip and one stationary, 180 degrees apart), for exactly the reason he was describing. The three-point gage may not necessarily show you the exact shape of the bore, but it will show you that the bore is not round, whereas the two-point gage may show a very similar reading all the way around when in reality, the bore is three- or five-pointed, etc.
Love how Dave lets us all see all this info. Amazing info Dave and team. Thank you all. Best channel on youtube
Fascinating content
One smart fella. Super informative. Great video Dave!
Great presentation Mark ,thank you Dave for the great knowledge !
You would never think its that indepth for cylinder honing. Great info. Mark my words 1 day i will be replacing my dmax with a monster dmax one day
Love the deep dive! Keep this stuff up!
Great video. Exceptionally educational.
Recently discovered your channel and subscribed - but shocked to see my cousin, Mark on here! 😂
Love Marks Movies 😂
So the Italian tune up has some merit 👍
Great video and info! Thanks for letting us watch!
I agree! I love tear down videos!
Sweet! I have to watch it again! Awesome!
Love this video so much information! I appreciate all you guys over there
Dave I said it before yall are the best
Fine technical explanation of surface treatments and effects. Ty.
Wow very informative! Thank you Dave and the crew.
That really was incredible information! Thank you!
Great video. Took me back to college. I now need to go back to therapy.
Learning is stimulating thanks 😊 for sharing 😊
Learning is fundamental
Absolutely fascinating. Thanks Dave!
Wow, that was awesome!! That gave me some great insight. Thanks Dave
So love techy!!!! Thanks Dave!!!!
Dave is the man!
Dave your right this is amazing stuff right here - mind blown for sure! Between Mark and Lake you & you sons are gonna be the smartest engine builders out there! 😂 Keep it up can't wait to see where this is going, especially with the Speed Of Air dimpled pistons coming into play now! I've been following the SOA guys for awhile & the number increases are just amazing! I need to get one of these built engines someday. Maybe someday my 7.3 will need a rebuild and I can toss in all the good stuff in the cylinders(SOA pistons, total seal, etc).👍🏻👌🏻🛠️🔧🚜⚡💥💨
@JAMSI needs to see this too
Very rigid tools and very sharp. Very fine diamond hones.
Dave you are awesome. Fan from the UK
that was very cool felt like I was there learning something. very nice work
That was an amazing video.
The repair industry doesn't need to go to that extent level of precision for the regular Joe. We rather need properly trained technicians and mechanics who wouldn't do stuff by trial and error most of the time.
Last year it took me 9 months to find someone who was willing to do chains and guides on a M62 engine. They were all either too afraid or lazy to deal with it. If I started talking to them about average surface roughness and stuff like that, they'd be looking at me as if I was a spacecraft...
Oh dude, im a shadetree guy and I would gladly take on M62 chains and guides. But I work on BMWs, so im fairly comfortable.
Lmfao
Love watching this next level. Keep up the great work
Sick video. Ty for sharing the knowledge
Awesome content thanks for sharing Dave!
