I honestly don't care a whole lot about diesel engines, but Dave has the amazing ability of making me want to watch every single video! Great channel!
So true
Me too, I've never owned a diesel vehicle but I enjoy the videos 👍🏻
You can tell that Joey also takes after his dad with his attention to detail. While talking, Dave touches Joey's freshly rebuilt engine with the tip of his finger, leaving a tiny grease spot. At 16:11, Joey then notices said grease spot and immediately grabs the nearest shop rag & wipes the engine clean, lol. Great stuff
I've only worked on my own gasoline engines but Dave and the boys seem like they are upper echelon mechanics. I know nothing about diesel engines and I watch each of these videos completely enthralled. They explain things so well and this video was like mechanic ASMR during the build with music portion. I love this channel. Great work fellas
I’m a simple man. I see a notification for a new upload for Dave’s Garage I tap and enjoy
This
Amen
Perfectly said.
Couldn't agree more
Amen!
As a mechanic on diesel engines for 47yrs. I noticed that these guys don't protect their skin from oil and diesel which is known in the industry to cause skin cancer and dermatitis. Should be wearing latex gloves or barrier cream. I was wearing gloves past 30 years. Love this content it's addictive.😊
do you think anyone want to listen to your nonsense, living causes cancer. no one needs some safety sally to tell them what to do.
My thoughts exactly
Yes the entire realm of automotive-engine work, was introduced to Nitrile gloves to keep us healthy.
only cancerous if it’s used
@@yafois988I find soap to be very useful as well. Preference is Dawn dish soap. Works great on greasy grime when working on engines.
Daves shop is the place where you take a truck with an engine problem & know not think KNOW, you can trust their word on what to do & what it'll run you. that piece of mind is priceless imho. Most of us watching have 28hrs of work we need to finish in the next 24 & still manage to sleep. Heck its Saturday at 3pm & i've been up for almost 12hrs & just now sat down to eat a bit before i head out to do more work.
I love it when clearance measuring is shown. Critical step and something many channels that try to be 'cool' skip showing!
I know they’re there to earn a living foremost, but man you can tell they have so much pride in their work. It’s so great they share it with all of us.
Dave's engines are much better built than any new engine from the OEMs. They don't do many of the assembly checks Dave's crew is doing. His rebuilding is more like a high end race shop. That's got to translate into more reliability.
Hats of to all of you guys.
That engine is so clean that persons hand are not even getting that dirty,
Greetings from Albania and all the best on what you guys are doing
You guys are awesome
If I were a much younger mechanic I’d be doing everything I could to be aloud to work in you shop, the quality of the work you guys do and the professionalism there is incredible and mostly a thing of the past, when you talk to your customers you give them honesty and the integrity of your entire shop, keep up the great work and keep sharing it with us all.
Let's just appreciate all the specialized machinery Dave has invested into his business.
There's no substitute for knowledge in a shop and this shop has it well done
Watching you guys work is like watching ‘Poetry in Motion’.
Dave and Guys: these are great to watch. Melted piston is hideous, but far less cost than a gas turbine (jet engine) with a failed and melted high pressure compressor (literally mega bucks to repair).
My old saying: "I love hard work, I could watch it all day long". However, I earned my retirement the old fashioned way, worked my butt off.
Keep it up guys, enjoy your day!
I really appreciate your videos, and thanks for letting us go behind the scenes of your shop.
I’m not a mechanic, but I can sit here all day and watch these videos.
Perfection , PLUS , at its best 👌👍. Man this is " good " to watch .
The tools and equipment , and above all the team you have using the " tools and equipment " - Awesome .
Wow! I just love watching these engines going together. Great content.
The cherry 🍒 on the cake would be seeing this built engine in action
I have never, nor will i ever build an engine. But i find your videos like this intriguing and very relaxing...something zen like watching highly skilled craftsmen in their flow.
It’s amazing how you rebuild engines a lot of patience. Good job Dave.👍😎👍🇺🇸
Wow, that pre-lube compression test at the end was fascinating.
Glad to see youth that gets dirty hands and CARES about the job they do. Hard to find.
That's the first time I see the crankshaft being balanced ❤
I bet Dave’s auto is a really fun place to work. The techs have the tools, the equipment location and support to turn out a really quality product. Reminds me of a factory authorized Rolex repair station, only with heavier stuff.
I love your videos… they are so fun to watch and you teach all us so much
If I was having an engine rebuilt, Monster engines would be the top of my list. You can tell they know what they are doing! Watching that engine come together is amazing.
Top Notch professional motor services! Very professional and organized! I wished I could get my 5.3 Chevy motor with 308k on it overhauled by you guys. Don’t think it would make the trip that far.😂
Thank you for another awesome video, it’s great to see real professional tradesmen at work. Watching from Perth Western Australia. 😁👍🇦🇺
Love this channel and the excellent work y'all do!
Watching that Duramax being rebuild was sublime!
*Dave's Auto Center* Bravo well done, thank-you gentlemen for taking the time to bring us along. GOD Bless.
I was hoping to see the block bored 0.030 over and reused, but with it also being cracked, that wasn't possible. You should look an electric drill up to the engine stand for rotating the block.
Great video on that melted rebuild Duramax , got love those air piston they will really help. Amazing how that piston fused to the block !
U are doing so good work, and I have work with Volvo car for 20yrs so i know 😊😊
Great video, would be cool to talk about the engine design and overhaul procedure differences versus other manufacturers
Dude has way more faith in that winch than I ever would.
What a fantastic video and a fantastic rebuild!!!!! God I love these videos. The only problem I see, and it's for US CONSUMERS/CUSTOMERS, not a problem for Dave or his business, is that since following Dave and the entire crew and the work they do, I would never ever ever want another person to touch my stuff. 🤣🤣🙏🙏 But I'm being serious. I know that there are tens of thousands of very talented mechanics out there, but the thoroughness of what these guys do combined with the equipment that they have, I just feel like they go quite a few steps above what the average wham-bam, get it out the door and down the road mechanic is going to do!!!! It's really too bad that doing things properly costs so much money. It makes sense though. Between the talent, the number of hours of labor, the equipment and the thoroughness… It has to be expensive. There's no way that it can't be. And that's why doing things the correct way cost big money… You get what you pay for. I don't see the average shop out there measuring every bore spec, cleaning every part and checking every clearance for all steps of the build like Dave does. I just don't see it. You can't compare an oil change/tire shop with a full-fledged machine shop. And that's why I would never want anybody else to ever touch my stuff again after seeing these guys. Put me in a real dilemma… 🤣🤣🤣🙏🙏🙏👍🏼👍🏼👍🏼🇺🇸🇺🇸🇺🇸🇺🇸🦅🦅🦅🦅🦅
One could only wish to find a shop as honest and reliable as this ❤
Speed of Air. I like it. 😊
Yes indeed! 😄
Wow. Amazing shop and employee's.
Good to see Joey out there getting it done
I am really curious to see a before and after of soot build up after installing the speed of air pistons.
Makes me want to send my engine out there just to have it made to last me my whole life and I’m 32 years young 😂
Thanks Dave ! your crew are the master minds of truck building 🤙🏻
OMG! I am an elevator mechanic. NEVER EVER GET UNDER A LOAD! Colby is under a suspended load.
Very educational I have a Duramax 2002.
I’m half tempted to blow my LB7 up, just so I can get a Dave top of the line rebuild. Lol Stage 2 Cam & those pistons? Yes, please!
Haha I know what you mean! And yes... those pistons...
If I had a diesel truck I'd be at your shop. Excellent work.
I have a 2019 Chevrolet 2500 HD. Only 21,000 miles myself on the Duramax. I always do my scheduled maintenance on it. Even did all the fluids from front to back at the 5 year mark. Wow, $$$$. But I want it to last forever. If I ever need a new motor, it’s going to come from you. I want the best of the best.
I like how he finally puts gloves on after pulling the crank lol, damage is done to those hands for the day
🤦🏻♂️🤡😂
Every time I see those speed of air pistons go in an engine build it feels like a total victory
One thing i highly aplreciate joey does is proper lubricating of fresh builds. I cant tell you how many people i know that will build a motor and put a drop of oil on a bearing and not even spread it out when they assemble a motor; or, not even lubricate the cylinders/valvetrain. Like tell me you couldnt care less without telling me, when you cant even do that.
Its just the little things honestly that go a long way.
I love engines can't wait for speed of air to drop their set for the l5p
Awesome looking build!--- way to go guys!
Awesome work 👍
Awesome video. You guys are true professionals !!
Love this format of video! Great work
With the expense of trucks now days and how bad people are with oil changes Dave is in no danger of ever running out of work! I am going to have them build me a new 4.8l for my mint 2003 Silverado I purchased from an elderly guy that kept it garaged, but he did drive it a lot and its got 200k on the odometer. He also drove it a long time with low oil pressure as it had the flattened Oil Pick Up Tube O-Ring issue. I am concerned it may have damaged it, but its running well enough to get me by until I need to do the project. I am saving up enough cash to do the engine and transmission at the same time and replacing all of the outer engine parts all new ignition coils (OEM) Water Pump, Alternator, etc. Having the front end rebuilt as well. Just watching all the problems people are having with all brands right now and the super high cost of new trucks I really think this is the way to go. The older trucks were super reliable and lasted 20 years no sweat. Already got about 6k saved up and set a side for the project as I do not like going in debt. Soon as I hit 12k that 2003 will be better than it was brand new! Yes I could easily do it now with a Jasper engine, but have you looked at the reviews as of late with Jasper? I want an engine as good as a new GM Crate since GM no longer makes the 4.8l Crate for those years.
Thanks for the show guys 🍻
I've never owned a diesel vehicle but , , , I enjoy watching the videos 👍🏻
How in the world does that go back together 🤷🏼♂️I strip that down it’s toast 😳😂😂😂brilliant guys
You guys should do a engine follow up , see how many of your rebuilds surpassed factory engines
I'm ordering an lbz long block next year, I'm hoping there is a video from daves comparing a Speed of Air engine to a stock reman, dyno sheets to fuel consumption, a torture test would be a cool bonus but would probably be a waste of time and effort, there would be enough money in the youtube video to pay for the engines themselves, I feel like there is enough demand. I'd really like to see some data before I drop 15k on an engine when I have the option to spend less than half that.
I really want to see one of these HP Diesels that you build on the Dyno. I want to see the improvements that gapless rings and Speed of Air Pistons make. For real world driving you should perform a test like TFL does on the Ike Gauntlet. I like seeing engines being built but I also like results, I need results. It's only going to help the business.
What percentage of Duramax's, Cummins' and Powerstrokes have major engine failures because of tunes?
And how many have failures because of poor maintenance?
yup my 6.0 blew its turbo seal but caught it, also a Ford industrial back hoe did a runaway on me, saved it by stuffing the intake, stuck governor
I'm curious what compound he was putting on the friction surface between the head bolt nuts and where they meet the head surface? I was always told to not put any anti-seize or similar on friction surfaces because it can throw off an applied torque. Have I been misinformed? Thanks for all your videos by the way, love watching them. Nice place you have out there!
Keepers are like a 10mil socket to a mechanic ( tec.)😊😊😊😊😊😊
Dave..your shop is dialed in. Very nice equipment.... and clean
I just love these videos!
a bit unusual to see bolts fixing lifting chains to head , heath and safety ,but still like the out come
5:50 I love how on todays melted duranax piston video, the piston damage wasn't done by the "leaking turbo seals" but what we know is the actual problem of the broken\damaged injector over spraying fuel into the hole and burning it up! Dave I don't doubt much of anything you say cause you know what you're doing well and have many decades of experience. But that previous video on this engine stated this melted piston damage was done by a turbo that had blown its seal and was sending oil into the engine causing this damage, which isn't the case. If that was the cause it would be all 8 pistons that got hot and damaged, not just one. The only thing that causes one cylinder to get too hot is too much fuel being dumped into it from bad injector like I said last video. I love to see you building the engine using @SOA dimpled pistons & I'm sure gapless @TotalSeal rings too. I wish we could see a side by side dyno, etc comparison between this and a regularly buit version? Anyways keep up the good work we'll be here waiting & warching!👌🏻👍🏻🛠️🔧🔩🛢️🦺
✊🏻🇺🇸🦅🇺🇸✊🏻
All that looks great, especially for the average person.
I bet you have 100% callbacks
Why did it only melt one piston if the turbo is pouring in oil. All pistons should have been burning oil like crazy!!
Just readin through the comments to say exactly what i was going to.Only one hole is not logical
Injector failure
@@JOMaMa.. yes
Speed of air pistons!!!!!!
This guys putting some serious bucks in this engine build with upgrades as well
I don't know much about diesel engines. However I am in the market for a new truck with a diesel engine due to the fact I pull heavy weight trailers on a daily basis. I would truly like to know your advice, what would you purchase ? 2024 f250, or 2024 gmc 2500. Powerstroke or duramax ? Those are the trucks I am considering.
These people really know there stuff.
17:50 sounds like a paradiddle on drums.
Halfway through that pressure test I almost started doing a cabbage patch
Quality work can be hard to find. This customer is getting a great motor.
I used to think dentists and mechanics were the bigger crooks out there. After watching this channel its nice to see theres still some good ones
It's the dealerships that are the problem
Very cool, Dave. You guys do great work.
God I love a good solid build, not a rebuild guy to any degree honestly stay away from it lol but mad respect to the guys that do it. Rebuilt my share of motors over the years mostly small engine water craft engines and I hated every second of it😂😂 they ran and chugged a long till they got sold to some out of town guy. I don’t mind redoing heads, but anything engine related tare downs and rebuilds make me cringe in pain😂respect to you guys going above and beyond anyone who needs and wants engine work I tell them you’re the guys. If I ever need engine work done I’m sending my stuff out to you
Dave, are you okay with the guy working under a suspended load like that near the beginning of the video?
Best videos and knowledge far reaching and shop
Craftsman! Efficient and precise.
Awesome!!!
Love these videos. I love the music even more, just wish I knew the song titles🤷🏻♂️
So cool. I'd love to know how to do all that stuff, wow. Great job!
Amazing!
Ty.
Dave - Love the channel and content, BUT having an employee under a suspended load?? No PPE worn by the employee?? Yikes!!! Room to improve IMO. Safety first...
Other channels uses have open doors without. Blowing. Thank you for being Xtra Clean
Don’t think it’s the safest to remove the oil pan when motor is on straps up on the air. Accident waiting to happen.
The naturally occurring oils and acids on your finger etches bearing surfaces
why no dampners, what does the spintron show? build any 7.1 strokers, better than just cranking up the boost
You installed the Speed of Air pistons, did you also use the True Seal gapless rings?
Nice!!!
