Can't get enough of these videos and what amazes me, they still have all their fingers, toes and surprise surprise, operational EYES.. The pure mechanical work being carried out here is something rarely seen now, for todays vehicle repair world is full of laptops and the adage of "Replacement" of faulty parts. Hats off to these guys who all have a job, a wage and a learning situation where they will eventually become the heirachy of the shop..
Sanchez. I can tell You've never wotked in a shop let alone a hazardous shop . You young whippersnappers think you know it all, when in fact your still wet behind the ears
Total admiration for these guys. When the wet season comes, either the workshop gets very crowded or perhaps they rig awnings. Either way, my hat's off to them 💪
In the 1950s I watched my father repair a warped head. He pulled the head and ground it flat on our concrete driveway. He drove that Goliath van for some years after that.
@@davidparker667 to be fair those old school engines don't have the tolerances or compression these new ones have. would you risk your time and money in parts and materials on a head you lapped yourself which may need to be redone? or send it out for 100$ and have zero worries? some head gaskets cost that much and if the head isn't perfect it will just blow again.
I've done my own with a block and abrasive paper on a diesel Passat. Granted it was an aluminium head and it wasn't excessively warped but it lasted for 8 years and 200k miles before I scrapped the car
There using modern day machining practices. Im a machinist and I can tell you we use the same tools here in the usa. They have a bridgeport kneemill made in bridgeport ct or its clone. The one gentle man @ 5:10 even mics the multi face vale angle. Besides the clothes everything here is similar minus hot tank.
@@markrich3271 Don't forget the pin gage at 4:00. Frankly most of the motions you see here you'd see in any shop that rebuilds engines. They'd just be using a bit more machinery to get things in their place. All the practical stuff is identical to any machine shop.
@@markrich3271 Nice to hear from a legitimate machinist rather than the 14-year olds in their parents' basement who seem to post most of the comments here.
Here is the proof. Everything can be made with a hammer. Small things can be made with a big hammer and big things can be made with an even bigger hammer. Excellent.
My grandfather was a Belfast carpenter, went to Hollyhead for work & stayed. He was in a Lonfon mechanic for 30 years used to flatten heads and blocks using a scraper and Prussian blue. Handlapped valves- was taught this by his father- a steam engineer. Swore mills were useless compared to a skilled smith. But beautiful fly cutting work here. Look at those anvils. Proper job.
I BOUGHT A FORD VAN(Old Sears Van) with a 302...It had a burned valve...it took me 3 days in Erinburgh, AZ (Next to Colorado River) To fix that burned valve...I HAND LAPPED THAT VALVE IN...YUP...IT COST ME A FEW CENTS SHORT OF $40.00...HEAD GASKET AND EX VALVE...THE 3 PLUG WIRES I TORE UP( Rotating engine to break head gasket loose) I found in a dumpster in Phoenix...yeah it limped back to Phoenix on 7 cylinders...worse than 1 it had before...3 mpg...it smelled so bad to those behind me...I apologise too!!!...PEE YOU...!!!
The fly cutting looks good because the millhead isn't trammed, it leans left a bit. You can tell because the leading cut isn't as deep as the following cut. The head should have a light circular crosshatching from both the leading and trailing cuts if done correctly. The result here will be a circular dip between edges in the middle of the flycutter's path. Pretty much guaranties a blown head gasket. Scraping is a real skill, good on your granddad. I once owned a Chevy Vega that warped its block every time you looked at it cross wise. I ended up just flat filling the thing. Probably lasted longer than this "fix" will.
I think we all wish your grandda had a chance to share with us how to outcut a lathe because I've seen a few old timers and I do believe they had a "feel" that was equal to a micrometer.
@@ChimeraActual If it isn't trammed, it won't leave circular cross hatching and will leave a dip in the middle. Why did you say the fly cutting look good?
When they were taking out the valve seats I was very curious whether they had replacements or what. But hell, they just made their own. What we're seeing here is what was done in the US in the 50s and 60s. Cool stuff.
Looked alright to me. Wasn't all that long ago a lot of guys reworked their engines. There were plenty of automotive machine shops around to get your machining done if it was needed. They would do as much or little as you wanted them to do. NAPA had shops at most of their locations. Most of the time you might have the heads surfaced if needed. Have new valve seats put in and ground. Bore or hone cylinders and grind crank journals if needed. Pick it all up and finish the rest in the garage. Parts have gotten so stupid in price it's not worth rebuilding anymore and much cheaper to just yank the motor and trade in on a reman unless you're into some kind of hot motor. Can't avoid that money pit anyway you go at it.
I was taught that to replace valve seats and valve guides I have to heat head to 160'C, cool other elements, and use thermal expansion of materials to get strong connection between them. But it seems to be incorrect, hammer and chisel is enough. What material they use for valve seats? Ordinary steel pipe? What a save of money! For mechanics of cource.
they use cast iron, these tortoiseshells are the ones we used 40 years ago, now we use steel tortoiseshells with higher strength. While the head is being heated, the tortoiseshell must be cooled. Greetings from turkey
Yeah, I was shocked to see them making their own valve seats. I did a bit of this type of work and we always just ordered them in. For us instead of heating the head we cooled the valve seats in liquid nitrogen to get them to contract. Really tight fit that way after they warmed back up.
The pipe is not made of steel, also made of cast iron who are good against wear. When I replaced the pipes in the cylinder head in the Toyota Hiace engine, these pipes was made of cast iron. And the other to example BMW engine, the pipes was made of bronze. The peoples who are working with the cylinder head are skilled to work with the old engines who are running year after year since 1950, really good work! Greetings from Norway and I has worked as car mechanic in 30 year.
Lol at all of the pussified comments, it's not a jet engine, if it works for them then that's the most important point, I'm sure that the engine would work just fine without the head cracking, valves flying out and coolant spraying everywhere as everyone in the comments section is suggesting, they've been doing this for a long time, do you think people would keep coming back to them if they did a bad job?
Yeah some guys just get enjoying out of criticising other mens work, half of them have never done any work on an engine and they are just parroting what others are saying, the guys in the video work with what they have and also with whatever knowledge was given to them, both are no doubt less than guys from the west doing similar work are given. And a lot of the crap the commenters say is pedantic text book BS, I grew up on a large farm we were often tearing diesel engines down and doing our own "country repairs" often out in a field with the deck of a truck as a workshop, the engines often got similar treatment to what you see here and I never saw anything fail because of it.
This isn't bragworthy lol. This is unsafe garbage performed by clueless m0r0ns. The amount of stress induced fractures and metal fatigue they are causing puts everyone who uses these trash restos lives at risk. If you sis it like this than you're just as pathetic.
Had a mentor in LA who said his Vietnamese helicopter mechanic was the best motoshop dude he ever saw. Machine guys are a special breed globally. I love wrench people.
We should be ashamed of our "progress".......we've abandoned the pride that comes from having a real skill and adopted button pushing and app running instead. Hat's off to these guys: superb teamwork and one hell of a lot of workshop skill being displayed.
@@leolego2 bro, no we don't. all that's change is the way we run them with cpu's bro. there has'nt been any real major performance gain worth to talk about bro.
@gary spooner I’m not sure you understand what lies behind the production of a new car. Literally thousands upon thousands of people are involved over a long period of time, from development to production. All those people have to make journeys to and from work, day after day. The designers, the engineers, all the people involved in production. Then all the people supplying thousands of components. Production and transportation of all those thousands of parts requires the use of huge amounts of energy, as does assembling them into the final product. Then there’s the energy used to recycle or dispose of the car at the end of its life. And I haven’t even mentioned the pollution caused by all those processes. So, no. Each improvement in fuel consumption is NOT worth the purchase, compared to what goes into producing a car in the first place.
@gary spooner 7% of the worlds CO2 is from steel mills. Keep telli g yourself that making new cars to save a few g/CO2 per kilometre is good green economy! The average 1 tonne of steel production puts out 1.5 tonnes of CO2. Add the manufacturing of the actual components to that and then the supply chain. Reuse will always beat renew.
I haven't seen that type of drills around for a long time they were called gutbusters justifiably these guys are amazing they are hungry in a way that we are not I hope that they will come forward in working conditions and equipment they are best hope to counter China in the region meanwhile we can learn a lot from these people I hope the children have a better future
i think we should go back to repair. Sometimes i cant reapir something because it was designed to break. Or these good damn clips everywhere. I hate them.
I prefer to use a jack hammer to remove the old gasket, It’s so much easier than a hammer & bolster & so much more fun. Looks like they did a tidy job I love head videos
Nothing fills me with more confidence than seeing hand clamps being used on a milling machine to hold the parts in position while trying to do a boring function.
I couldn't believe they just used the mills quill and a straight to get the depth of the valve seat. They must be rebuilding this thing within a 0.5mm tolerance instead of 0.05mm. Ahh well time is money and this is a very quick way/ dodgy way of working.
These people do a fantastic job on just about everything and with minimal tools. Some of their tools are handmade too. To them there is no such thing as impossible. I respect them very much. They need safety glasses though. I've been to Mexico and work like this is done in some of the remote villages too.
Rectificación de culata. Un trabajo de alta presición. En el vídeo vemos el encasquillado de asiento de válvulas. De una culata de motor a diésel. De 14 años a 18 años me dediqué a ese oficio. Un hermano aún tiene su taller.
I love watching these videos, chalk and cheese , and the bath cleaner looks like old oil from years ago. So what it works for them and it works for me watching them thanks guys 👍👍👏👏
Subscribed👍 looks like they are rebuilding Hamilton and Verstapen’s old F1 2021 engines here😂 joking aside,, these shop mechanics needs to be payed more for their hardwork👏
Primitive tools and equipment, dangerous working conditions, and yet these guys are doing a masterful job. Also, two people on every operation is a good thing.
Except the lack of safety and sanitation, all the tools they have are pretty standard in a typical machine shop here in Europe for engine rebuild. I wouldn’t call them primitive at all.
@@Spiritdreams By 'primitive' I didn't mean unqualified, I meant typical automotive machine shop equipment that's been around for at least the last 50 years. That's how long I've been in this business. Those machines, with the right operators, can turn out 100% quality work.
@@rollydoucet8909 Nobody meant unqualified either. They are repairing pieces. I am not saying that it's impossible to use a CNC to repair, but unless you have a lot of the same piece to repair with the same problems, what is the point of making a program for it when you could just center it on a conventional? Even if they had the money for more they would probably stick to this.
This is a top high tech place because I saw one guy sitting on a chair and another guy with closed toe shoes. That’s some next level shit, right there.
WHAT AMAZES ME...IS HOW CLEAN AND PRECISE THESE HEADS (& ENGINES GO BACK TOGETHER...I WOULD RUN THESE HEADS ON MY EQUIPTMENT...I WOULDN'T EVEN BREATH HARD WORRYING...I SEE HOW THE PEOPLE OF INDIA RUN LOADS ON THEIR TRUCKS & BUSES...GOOD JOB...!!!
Give me a philips head screwdriver and a plier and I can dismantle and re-assemble a B747 in 3 hours... Fuck your Ferraris and Lamborghinis and your Bentleys and Rolls Royce and fuck you... You think if a white man isn't doing it it's not getting done... Fuck you... We do it and we do it better... If you don't believe me just check the census who's got the bigger population... Wanker...
What these guys do on a daily basis is something that we need specialist workshops for in the West. Granted, the tolerances they work to are bigger, but they do proper REPAIR work rather than just replacing stuff. I hope they take pride in their work because they really should! Amazing, the things you can fix with a hammer 😁
@Thor Odin son Honestly you have zero idea what you're looking at if you say "zero consistency" because they use all the same techniques we use here in the US and likely your country too, they just do it with tools that have been in use for much longer with crap appearances. You'll see them use straight edges, micrometers, and reference calipers to double check everyone's work (including the mills) because they don't want it to come back for a redo. Everyone who has built an engine knows what's going on here, they just do it in less safe and dirtier conditions.
I like the anvil type workbenches with adjustable height, seriously sturdy for working smart, not hard. I have wrapped steel wool around a piece of wood in a drill to polish ports myself and it does work surprisingly well.
@@garrykennedy5484 thats the cringe part for me, solvent get absorbed so easily, its probably diesel or kerosene since its readily available and the less worst solvents
@@robertficek7586 the guy wearing sandles in a machine shop covered in grime and metal shavings is what got me......that and the guy using a grinding stone and doing saftey squints.
the first thing is that the Germans would have a heart attack with the standards of safety so low other than that it would be a good team going forward.
We don't really know how good the work is.Unless you can attest to the fit and measurement of each part,you can not say for certain that the guides won't seize or the seats won't drop or even that the heads are not cracked.but for working on and in the dirt and using a sledge hammer as the only tool,and really dirty gasoline or diesel or kerosene,its entertaining to watch.one thing i wonder if they use stainless for the seats or just seamless tubing,like pipe or maybe pump shaft its cheap.
Finally, someone is on a table instead of the dirty floor. I HATE OSHA, but these fellas really need safety glasses. You only get 2 eyes, so don't poke one out with a flying shaving of metal.
There was a time when there were automotive machine shops in every city and town in the USA that did this type of work. Most are gone now along with the equipment and skill to use that equipment.
Yes, and that is sad. As a diesel mechanic for more than 20 years, it's so hard to find people that are willing to get dirty like we do for good money! People don't realize the skills it takes to be not just average, but to be really very good at doing this kind of work. My background was mainly track equipment, and heavy cranes. But when I stuffed a 2000 LS1 into my 1986 Mazda RX7, and then put an 8.8 IRS out of a ford T bird super coupe in the rear end, and went 12 seconds flat in a 1/4 mile on stock parts, people start to notice! When they heard the gas milage was 29 per gallon, then they turned hard. When it went 165MPH I had their attention, and when it turn on a dime and stopped faster than the Z06. I was noticed! When I was just getting started in diesel( which I never was interested in), my old boss always used to say,,,"Son, ya gotta be smarter than the equipment," I had no idea how much that sentence really had to say, until a few years later. He was so right! The other thing he used to say was, "Ain't nothing money can't fix!" Well, ain't that the truth!
@@billk9628 außer, ein kaputtes Herz ❤- dass kann nur mit Liebe anstatt Geld repariert werden- mit allem anderen bin ich deiner Meinung u Bewunderung !
Datsun Dan: Maybe I missed it, but I didn't even see them surface that head. Looked like they just flycut it. Put a cheater on the head bolts and maybe it will seal.. Ya think? :) Looks like a little Perkins diesel head.
i am 88 did a lot of repair in my days but i have never seen this talent before you see those you kids working along side the men they will be the experts next generation i dont think they make enough to pay for shoes they live in tiny huts side of thr road . one think you can see they never argue among them selfs they seem to know what to do next on every thing.
Great skills and common sense. These guys would be a match for anyone, including Rolls-Royce. Amazing how they achieve these perfect results in a less than perfect work environment.
Enjoyed watching The guy doing the clean up ( assuming he’s using solvent tank ) is going to destroy his hands. That’s why they use young people for that job.
All the ways we would have done it in the USA in the 1940's & 50's ... Low speed diesel engine, so no critical valve harmonics to deal with. Very slow easy cam profiles so no rapid or abrupt valve motion. All good work. Checked themselves as they went. Looks good !!
Probably this: They have no safety minded culture, so there's a lot of injuries. When they do their backs in, or they have ruined eyesight, they can't work, but they are the owner, or the owner's uncle or some such, so they get to just sit around and give advice.
Seems like almost all start as apprentice at twelve and never look back. Steady life long work. A cottage industry with astounding level of skills. The last ten seconds I suspect he was tapping the valve springs to see if they made the same sound. Just guessing
A few takeaways we can all learn from:: Rarely do you see such a variety of reciprocating presses in actual precision use! The RA finish on that one head surface was clearly for an MLS head gasket. Don't get ripped off by machine shops that unnecessarily invest in equipment when properly trained kids.. er staff, can make squared up valve grinds with hand drills. No Dremel tooling necessary when you have a good 1" drill Always insist the final product is saran wrapped before leaving the clean room assembly area, as shown here...
Huh valve seat from regular steel? How the hell is that going to hold? Also just hammering things ...It would be interesting what happens when this engine reach normal temperature.

I first left school in the UK. Still remain good friends after forty years.
Had a mentor in LA who said his Vietnamese helicopter mechanic was the best motoshop dude he ever saw. Machine guys are a special breed globally. I love wrench people.
We should be ashamed of our "progress".......we've abandoned the pride that comes from having a real skill and adopted button pushing and app running instead. Hat's off to these guys: superb teamwork and one hell of a lot of workshop skill being displayed.
I agree, we don't even know how to replicate the engine that took us to the moon in the 60's, alot of craft has already been lost in 2 generation's
@@pizzaki582 we have much better engines than the one that took us to the moon bro
@@leolego2 bro, no we don't. all that's change is the way we run them with cpu's bro.
there has'nt been any real major performance gain worth to talk about bro.
Totally good fix for the next 5 months!! 👏🏻👏🏻
The “Greenest” thing we can do is keep the things we already own going, and not buy shiny new crap with built in obsolescence.
@gary spooner I’m not sure you understand what lies behind the production of a new car. Literally thousands upon thousands of people are involved over a long period of time, from development to production. All those people have to make journeys to and from work, day after day. The designers, the engineers, all the people involved in production. Then all the people supplying thousands of components. Production and transportation of all those thousands of parts requires the use of huge amounts of energy, as does assembling them into the final product. Then there’s the energy used to recycle or dispose of the car at the end of its life. And I haven’t even mentioned the pollution caused by all those processes.
So, no. Each improvement in fuel consumption is NOT worth the purchase, compared to what goes into producing a car in the first place.
@@numberstation and all those thousands of people have jobs to support their families,
@gary spooner 7% of the worlds CO2 is from steel mills. Keep telli g yourself that making new cars to save a few g/CO2 per kilometre is good green economy!
The average 1 tonne of steel production puts out 1.5 tonnes of CO2.
Add the manufacturing of the actual components to that and then the supply chain. Reuse will always beat renew.
I haven't seen that type of drills around for a long time they were called gutbusters justifiably these guys are amazing they are hungry in a way that we are not I hope that they will come forward in working conditions and equipment they are best hope to counter China in the region meanwhile we can learn a lot from these people I hope the children have a better future
I have one of those drills, got from dad, we call it the widow maker. There's no stopping it.
Hustle is better than Muscle. Every time
Vincent : God bless you
i think we should go back to repair. Sometimes i cant reapir something because it was designed to break. Or these good damn clips everywhere. I hate them.
Красавчики мужики, все делают, руки набиты, молодцы.
I prefer to use a jack hammer to remove the old gasket, It’s so much easier than a hammer & bolster & so much more fun.
Looks like they did a tidy job
I love head videos
Nothing fills me with more confidence than seeing hand clamps being used on a milling machine to hold the parts in position while trying to do a boring function.
Well to be fair they did have a nice rig set up to use the stem part of the valve stem as a centering guide. But eh not ideal, but when in Rome.
Yup, that and an untrammed mill.
I couldn't believe they just used the mills quill and a straight to get the depth of the valve seat. They must be rebuilding this thing within a 0.5mm tolerance instead of 0.05mm. Ahh well time is money and this is a very quick way/ dodgy way of working.
@@Ken-nv2hl Ah yes, but the precision in their haircuts makes up for it.
Very good job, but steel quality on valve saddles and valves by it self !? Workers done good job but for how long?!
Is this the Dorman remanufactured engine parts division?
Why yes it is, good eye.
They also refubish Moog, Eaton, Timken, and TRW parts. They look and feel like the real deal.......Until you install them
These people do a fantastic job on just about everything and with minimal tools. Some of their tools are handmade too. To them there is no such thing as impossible. I respect them very much. They need safety glasses though. I've been to Mexico and work like this is done in some of the remote villages too.
This takes place in every corner of the world where c there are automobiles. Lol, some far remote places in mexico????? Haha
This must be a cool place to work: everyone pitches up in their pyjamas!!
Svaka cast majstori veliki pozdrav za vas...
Rectificación de culata. Un trabajo de alta presición. En el vídeo vemos el encasquillado de asiento de válvulas. De una culata de motor a diésel. De 14 años a 18 años me dediqué a ese oficio. Un hermano aún tiene su taller.
I love watching these videos, chalk and cheese , and the bath cleaner looks like old oil from years ago. So what it works for them and it works for me watching them thanks guys 👍👍👏👏
How that man remembers where everything goes I will never know... I was lost during disassembly, and had to drink a beer...
Proper job can do all my work if they were round the corner or in the uk
Very hard workers and very professional thanks for sharing
And its all done by guys wearing sandals with no H&S man in sight. When the revolution comes I want these blokes on my team.
Floor benches leather(human) gloves and sandls are mandatory there
But how close to spec. Is there work? or does it just need to run.?
Safety comes first at this factories 😂😁🤣 amazing work though
Subscribed👍 looks like they are rebuilding Hamilton and Verstapen’s old F1 2021 engines here😂 joking aside,, these shop mechanics needs to be payed more for their hardwork👏
Primitive tools and equipment, dangerous working conditions, and yet these guys are doing a masterful job. Also, two people on every operation is a good thing.
Nice work
*** you mean primitive
They are using a mill and I can see a lathe in the back.
It's not a CNC but for reparations it's pretty damn good
Except the lack of safety and sanitation, all the tools they have are pretty standard in a typical machine shop here in Europe for engine rebuild. I wouldn’t call them primitive at all.
@@Spiritdreams By 'primitive' I didn't mean unqualified, I meant typical automotive machine shop equipment that's been around for at least the last 50 years. That's how long I've been in this business. Those machines, with the right operators, can turn out 100% quality work.
@@rollydoucet8909 Nobody meant unqualified either.
They are repairing pieces.
I am not saying that it's impossible to use a CNC to repair, but unless you have a lot of the same piece to repair with the same problems, what is the point of making a program for it when you could just center it on a conventional? Even if they had the money for more they would probably stick to this.
This is a top high tech place because I saw one guy sitting on a chair and another guy with closed toe shoes. That’s some next level shit, right there.
I love that spring compressor
I removed valves with a hammer and scrap pipe when I was in the cylinder head business, I like the home made spring compressor too
@@mikecampbell5452 Yeah, that thing worked well, and it was fast, too. They get points for that.
WHAT AMAZES ME...IS HOW CLEAN AND PRECISE THESE HEADS (& ENGINES GO BACK TOGETHER...I WOULD RUN THESE HEADS ON MY EQUIPTMENT...I WOULDN'T EVEN BREATH HARD WORRYING...I SEE HOW THE PEOPLE OF INDIA RUN LOADS ON THEIR TRUCKS & BUSES...GOOD JOB...!!!

Give me a philips head screwdriver and a plier and I can dismantle and re-assemble a B747 in 3 hours... Fuck your Ferraris and Lamborghinis and your Bentleys and Rolls Royce and fuck you... You think if a white man isn't doing it it's not getting done... Fuck you... We do it and we do it better... If you don't believe me just check the census who's got the bigger population... Wanker...
A very good workshop indeed.
Overall, excellent teamwork! Please get these guys some eye protection!
Absolutely agreed! No complaining either.
Would have loved to see the engine running. Great video.
What these guys do on a daily basis is something that we need specialist workshops for in the West. Granted, the tolerances they work to are bigger, but they do proper REPAIR work rather than just replacing stuff. I hope they take pride in their work because they really should!
Amazing, the things you can fix with a hammer 😁
There are shops like these in the west, just more expensive.
@Thor Odin son Honestly you have zero idea what you're looking at if you say "zero consistency" because they use all the same techniques we use here in the US and likely your country too, they just do it with tools that have been in use for much longer with crap appearances. You'll see them use straight edges, micrometers, and reference calipers to double check everyone's work (including the mills) because they don't want it to come back for a redo. Everyone who has built an engine knows what's going on here, they just do it in less safe and dirtier conditions.
3rd world craftsmanship...... It is make do with what you have.... Brilliant.
I can feel the metal splinters from the drill in the ports through the screen
I hope this video inspire people to get work done, no excuses men
Luis : ja , leider ist heute die Meinung : Kaputt ? Neu kaufen ! - Ich bin kein Mechaniker aber ich versuche alles was ich kann selber zu reparieren
Good workmanship , nicely equiped machine shop ,good to see the work being done in the time honoured way.
Yeah. Nail it.
in his ass@@veritasaequitas9875
Great job, even lapped those valves in!
ما شاء الله تبارك الله يا رب ارزقهم
I like the anvil type workbenches with adjustable height, seriously sturdy for working smart, not hard. I have wrapped steel wool around a piece of wood in a drill to polish ports myself and it does work surprisingly well.
Today we finished rebuilding a nissan engine with two heads just like this. Its nice to know what goes on in the machine shop.
Bravo bravo bravo, maestralno
Warning: NEVER wear safety glasses when grinding or resurfacing metal parts.
🤣🤣
Or gloves when handling solvents.
@@garrykennedy5484 thats the cringe part for me, solvent get absorbed so easily, its probably diesel or kerosene since its readily available and the less worst solvents
@@robertficek7586 the guy wearing sandles in a machine shop covered in grime and metal shavings is what got me......that and the guy using a grinding stone and doing saftey squints.
just squint or look away.
What a great set of good Mechanical videos on youtube lately! If these guys team up with the Germans, hello superpower.
the first thing is that the Germans would have a heart attack with the standards of safety so low other than that it would be a good team going forward.
@@muazamazad7713 at least their level of quality is better then German car makers.
@@adelaseeri768 Any proof ?
We don't really know how good the work is.Unless you can attest to the fit and measurement of each part,you can not say for certain that the guides won't seize or the seats won't drop or even that the heads are not cracked.but for working on and in the dirt and using a sledge hammer as the only tool,and really dirty gasoline or diesel or kerosene,its entertaining to watch.one thing i wonder if they use stainless for the seats or just seamless tubing,like pipe or maybe pump shaft its cheap.
Looks like cast iron.
Great job working with what you have.
Finally, someone is on a table instead of the dirty floor.
I HATE OSHA, but these fellas really need safety glasses. You only get 2 eyes, so don't poke one out with a flying shaving of metal.
Why would you HATE OSHA ?
Did the Germans use eye protection when the bombed Pearl Harbor ?!
@@stevephillips3541 Yes they did
Looks a happy place, plenty of people to talk to.
Опрессовку надо делать обязательно!!! Иначе все работы насмарку!

Великолепная работа👍
There was a time when there were automotive machine shops in every city and town in the USA that did this type of work. Most are gone now along with the equipment and skill to use that equipment.
There still... are... there's a machine shop or 10 in every major city that will rebuild and resurface a head.
Yes, and that is sad. As a diesel mechanic for more than 20 years, it's so hard to find people that are willing to get dirty like we do for good money! People don't realize the skills it takes to be not just average, but to be really very good at doing this kind of work. My background was mainly track equipment, and heavy cranes. But when I stuffed a 2000 LS1 into my 1986 Mazda RX7, and then put an 8.8 IRS out of a ford T bird super coupe in the rear end, and went 12 seconds flat in a 1/4 mile on stock parts, people start to notice! When they heard the gas milage was 29 per gallon, then they turned hard. When it went 165MPH I had their attention, and when it turn on a dime and stopped faster than the Z06. I was noticed! When I was just getting started in diesel( which I never was interested in), my old boss always used to say,,,"Son, ya gotta be smarter than the equipment," I had no idea how much that sentence really had to say, until a few years later. He was so right! The other thing he used to say was, "Ain't nothing money can't fix!" Well, ain't that the truth!
@@billk9628 außer, ein kaputtes Herz ❤- dass kann nur mit Liebe anstatt Geld repariert werden- mit allem anderen bin ich deiner Meinung u Bewunderung !
Great workmanship.
freshly surfaced head? Just drop and drag it along a gritty, metal chip riddled work surface.
Too precise for these guys
The seen heads are now available at a store near you hahah
Datsun Dan:
Maybe I missed it, but I didn't even see them surface that head. Looked like they just flycut it. Put a cheater on the head bolts and maybe it will seal.. Ya think? :)
Looks like a little Perkins diesel head.
American aren’t you?
You guys are brilliant
Super grundig renovering og rensning❤️❤️❤️🏁🏁🏁🇩🇰
i am 88 did a lot of repair in my days but i have never seen this talent before you see those you kids working along side the men they will be the experts next generation i dont think they make enough to pay for shoes they live in tiny huts side of thr road . one think you can see they never argue among them selfs they seem to know what to do next on every thing.
Great skills and common sense. These guys would be a match for anyone, including Rolls-Royce. Amazing how they achieve these perfect results in a less than perfect work environment.
You must have no clue. These guys are total hacks non of these engines will last very long
Perfect results? Im sorry but how did you come to that conclusion, The only measurements they took were with a straight edge and a ruler.
Perfect results. How do you figure?
Yes you are right these guys are very talented!
🥰 what an amazin skill. great job!
These guys are truly amazing.
Enjoyed watching
The guy doing the clean up ( assuming he’s using solvent tank )
is going to destroy his hands. That’s why they use young people for that job.
All the ways we would have done it in the USA in the 1940's & 50's ... Low speed diesel engine, so no critical valve harmonics to deal with. Very slow easy cam profiles so no rapid or abrupt valve motion. All good work. Checked themselves as they went. Looks good !!
My father used to work on trucks, exactly like this until he lost 3 fingers, then he worked on trucks with 6 fingers and two thumbs
Having seen how the finished engine is treated,I would agree that the " fixing" suites the application.
Who needs PPE, when you have a badass mustache!
I tell you these guys certainly do a good job
I think these guys are amazing.
These guys would walk circles around any American master mechanic all day
you're delusional
And hand him tools.
So they coated one face with oil then turned it upside down on a table covered with metal filings?
How come there's always someone just sitting around in a chair in the background?
Maybe they take turns resting 😀
Probably this: They have no safety minded culture, so there's a lot of injuries. When they do their backs in, or they have ruined eyesight, they can't work, but they are the owner, or the owner's uncle or some such, so they get to just sit around and give advice.
Начальник цеха- босс
Love the quality control...
Seems like almost all start as apprentice at twelve and never look back. Steady life long work. A cottage industry with astounding level of skills. The last ten seconds I suspect he was tapping the valve springs to see if they made the same sound. Just guessing
No he hits them in order to confirm that the bits that secure the assembly together are securely in place.
السلام عليكم عمل جيد جدا وفقكم الله
A few takeaways we can all learn from::
Rarely do you see such a variety of reciprocating presses in actual precision use!
The RA finish on that one head surface was clearly for an MLS head gasket.
Don't get ripped off by machine shops that unnecessarily invest in equipment when properly trained kids.. er staff, can make squared up valve grinds with hand drills.
No Dremel tooling necessary when you have a good 1" drill
Always insist the final product is saran wrapped before leaving the clean room assembly area, as shown here...
Huh valve seat from regular steel? How the hell is that going to hold? Also just hammering things ...It would be interesting what happens when this engine reach normal temperature.
