- Cracks typically form when a cylinder head undergoes too much thermal stress. Loss of coolant, severe overheating as well as sudden changes in operating temperature from hot to cold can all create the kind of conditions that cause cracks to form.

People don't have a clue as to how much time and effort it takes to fix things. Today everything is made to throw away. These guys really earn their money. This is a really good look into how things get fixed. Thanks for sharing guys!!👍
Other than the lack of benches and working on the floor, this is EXACTLY how we did it here in Scotland 25 years ago, when I worked for a small engine repair business. Even the machine tools are the same.... The twin of the big drilling machine they are using to cut valve seats, lives in my workshop.
was it then when alot of factories moved to pakistan from the uk?
can you explain why he drills holes at 6:30?
@@space_cowboy007 he's using the drill to clear out the rust and muck from the small water passages.
I'm also don't understand why these people don't us benches but I wonder if that crack isn't coming back?
@@CactosS do search for metal stitching, works pretty well !!
my knee blew out watching all these videos of these guys crouching down......
These guys have a go. It's very primitive but at the end of the day it will work and i just can't understand why they haven't found benches yet? My back and legs were killing me just watching it.
After you are born, you do the Asian squat everyday for the rest of your life. No need for chairs , or high type toilets. In fact, they squat on a western toilet .
That would require resources and those can be best used elsewhere where people can afford to spend money on dead tree that would be better used selling as fire wood or to make and sell the table.
I'm not even joking.
Sad thing is in any other country that head would have been melted down for scrap and the whole truck would have been scrapped years ago.
They prefer to work that way, if they preferred benches they would have them. It's similar in lots of countries, to them standing all day is awful they find this way more comfortable it's like sitting and working. I was married to an Indonesian for years it's the same there, we had a house in Java I made a modern kitchen with benches and my ex wouldn't use the bench for cooking, she preferred to have everything spread out around her on the floor while she sat in the full squat position for hours preparing a meal, if i try squatting down like that for just 10 minutes straight my legs start to feel like they are going to fall off and when I try to get up my knees are seized and my legs are numb from lack of blood.
@Random contaminate free doesn't guarantee a good job. But grit and shite all over a cylinder head definitely guarantees a poor job.
My knees couldn't take that squatting down like that very long before i did something about it one way or another. I'd make a homemade bench from a tree if i had to.
What I like about these guys is that they
REPAIR things they don't just simply unbolt a
Broken part and bolt on a new one..
This is how I imagine Mad Max rebuilds his engines. I love it.

They do it exactly the same as it happened in my dads garage in the 70’s and 80’s, the only difference is they work on floor and in sand instead of on the workbench but the techniques is simply the same, i have been helping as kid with this kind of work
These guys are real heroes. I love the way they approach the jobs with adapted tools and methods they have figured out themselves. I was spellbound throughout!
Their work environment may look primitive but am always astounded by the ingenuity of all their projects,well done guys👌👌
I like how they clean off the parts, then lay them back down on the dirt...I guess it helps in the break in process.....comforting knowing most major airlines send their fleets over there too for updating and rebuilding.
Get over it
But admit they are good for doing all that in the dirt in the first place

I just went into cylinder head repair, and this just knocked all the B.S. out of it.
On a dirt floor, in the 3rd world.
Great job!!
I spent nearly 40 years as a cylinder head specialist I have rebuilt many thousands of heads and repaired thousands of cracked heads but this is very crude although it might work . I used tapered cast iron plugs not bolts. But what they really need is a bench.
in countries where new parts are expensive and labour is cheap, you'll see a lot of ingenuity and hard work in rebuilding broken things.
They do those same techniques at machine shops everywhere pinning cast iron heads is a very old technique they even use it on aluminum heads. I have put heads on cars that were pinned.
Hard work, yes. Nothing special about the method.
@@brahtrumpwonbigly7309 in pakistan it's nothing short of genius and state of the art.
A lot of the parts are made of unobtainium in Pakistan or anywhere else.
@@fixinggrace They also use old AK-47 Barrels
Thanks Mate for uploading this video. I learned something New today. Using (CALCIUM CARBIDE) to check for leaks. Brilliant Idea. I never would've thought of using this for Leak check. The only time I've use this product was exploring Caves. I used it as Fuel to charge my Old Timer Lantern for Light while exploring Cave System. Now I have One more Tool in the Box, I could Employ without using Air Compressor when one isn't around. Thanks again Mate for the upload. I do appreciate this very much. Well worth the watch.
So that's what those "rocks" were that they put in the head! Great idea. For those of you who don't know, Calcium Carbide reacts with water to form acetylene gas - the gas pressure forces the water out the cracks.
@@joeylawn36111 don't smoke near it hahahahhaha for real though
@@joeylawn36111 The pressurized acetylene also makes the cylinder head into a giant fuckin' pipe bomb. 😸 I laughed when I saw them doing this. Don't uncork that thing near the head surface grinder... Kaboom, and now everyone in the shop can no longer enter an MRI room. 🤣
Throws in the dirt and then wipes it with the rag to keep it clean,love it
Retired now,when I was working we fixed a lot of things,before anything new was purchased that part or whatever better be totally worn out,I've done heads and blocks it work's, I'm very impressed with their work
Used to do this on 235 Chevy heads all the time, works well!
What bolts are you using? Thanks
I have pinned cylinder heads before. And have watched my father pin a Cat block that had frozen and cracked the side. It is a lost art. But still a useful tool that has been put on the back shelf here in the States,
The way these men can repair what we have scraped is amazing
Outstanding work on an obviously worn out cylinder head.
An ingenious fix on the cracked section.
I almost cried at 25:55 when he dropped the newly machined mating surface on the concrete to remove loose swarf....😫😭😳!
Nothing gets wasted. I find this people smart. They can fix anything w/o any manual
The best work doesn't always come from the factory these guys really know what they're doing it's a trade it's very crafty and crafty and it's very awesome because most people do not have what it takes to be able to do this the way that this is being done nice work man

Great work! I bet anyone living in remote, rural areas would very much value that work.
Смотря этот ролик я думаю - даже самый плохой ремонт у нас - как минимум не хуже чем тут. Но почему-то я этому не рад совсем. Потому что у нас кто-то может заниматься ремонтом точно также.

You are right!
Какие мастера? У нас это делали так в колхозах 30 годах прошлого века. О чем вы бля говорите.

As someone who runs a serdi machine and works in a machine shop every day this is amazing stuff!! From one end of the spectrum to the other I guess...
Still positively amazed at the skills of these workers. Here in the United States we would throw it away, we are stupid here at times. Thanks for sharing the amazing work of these fine men. Best Wishes & Blessings. Keith Noneya
You do know there are places called "machine shops" that exist here in the USA. Look for some videos here on the tube and you'll see what they are capable of.
@@aaronmccutcheon Yep have visited more of those shops than I can count. It's the cracked part that amazes me. Here in the state we just throw the head away and get another one because in most cases in man hours it's cheaper to replace a cracked head than repair it. Except Aluminum, most of the time we can Heli-Arc them up and machine them down. Thanks for the tip anyways. Best Wishes & Blessings. Keith Noneya
I so much admire these Gentlemen. Although I have a more modern machine shop and tools, these men follow the same basic principles. And better. We can buy standard valve guide inserts and valve inserts. But due to delays, I, just like these men, make my own sleeves a seats myself. It ends up quicker and it continually hones your machinist sense of touch. By that, I mean that instinctive feeling of when something is ready to press. Like valve stem guides and valve seats. Even I do not have the experience to use just an inside or outside non-microscopic caliper to judge a size! That is hundreds of hours in the job that speaks!
The work ethic an ingenuity shown here are amazing. We’ll played men!
my compression cried when the guy took the head off the resurfacing machine only to throw it on its face to get rid of the shavings

they are true mechanics, able to fix stuff instead of replacing it with new.
really? like you know this truck doesn't come back on the hook with a bigger problem!
Absolute amazing and excellent repair, or rebuild work being done - great job, God Bless!
Was Ihr mit einfachsten Werkzeugen und Maschinen macht ist ein Traum, habe sehr grossen Respekt vor euch, weil Ihr seid noch wirkliche Mechaniker wo repariert und nicht nur Teile tauscht. Und finde es klasse das Ihr euer Wissen und Talent an die kommende Generation weitergeben tut. Das einzige was ich mich immer nur frage,weshalb arbeitet Ihr nicht auf einer Werkbank, sondern immer auf dem Boden.
Ich kann nur vermuten, ich glaube aber dass es zu teuer ist, den Werkstatt mit Werkbanken auszustatten.. man sieht ja dass der Boden nicht mal Beton ist.. kann aber auch die Kultur sein.. in der Arabischen/Westasiatischen Kultur macht man vieles auf dem Boden.. früher haben wir gegessen, gesessen, geschlafen,… nur auf dem Boden, in den Moscheen sitzt/betet man auch auf dem Boden.. sogar wenn man aufs Klo gehen möchte gibt’s da Toilettensitze nur für Senioren oder Behinderte.. sonst wie in Japan auf Bodenebene..
they are accustomed from childhood to work on the ground
@@ukpkmkk_2 صح كلام
I agree with many of these comments. The skill and knowledge of these guys is impressive. Please work on a bench like a human, k no it squatting on the floor like a primate
when you are looking for skills that are extinct these days because of rich countries automation era , you will find it in Pakistan and India , I love the way they work and the skills that they gain even with little tools but they have great brains they use to outcome a complete work of their need , good luck
Indeed these guys are impressive (though why are they always squatting on the ground? Tables are pretty easy to make!) However there are numerous machine shops throughout the USA that can do things far more difficult than these guys can do.
Love your videos. Keep it up. You bring me some of the most entertaining videos on youtube.
Интересные эти зверьки 😁 тряпкой протирает и тут же на землю клапана бросает. Чудо.
🤣🤣🤣
Это традиция.
@@Анеботакоеже точно 😁
Pinning cracks, also called lacing, is something we did in the machine shop I worked in over 50 years ago. We used purpose made tapered cast iron threaded pins and locktite. The pins were designed to snap off at a specific torque to ensure correct installation. For long cracks we would partially drill into the first pin, install a 2nd pin, and so on for the entire crack. Never had a come back or issue.
This place reminds me of the car repair shops they used to have next to the baseball stadium in NYC.
Jak oni to fajnie elegancko czyszczą w tym piachu 😂👏🏻👏🏻👏🏻👍🏻greate job
I am in awe of your chaps skills, you have my admiration in hard circumstances… stunning work.
I wish I had these master craftsmen on my doorstep. Such masterful work
Excellent video, reminding us that you don't need all the fancy gear to get the job done, just will and skill. Keep them coming.
Well. This would work on an old, low compression engine.
@@dimr1088 well, do you realise this is an old DIESEL engine, so not really low compression at all.
As long as the mechanic that puts it back together cleans everything real good, that was a mighty fine job.
I bet it runs like new.
I can remember watching my dad and uncle doing this same thing when I was a kid, when it's on an old 2500 dollar forklift you don't go buy new you fix it until it can't be fix no more
Very very good work that's old school way to clean valves nice professional work very clean .they take a lot of pride in doing the job right.good work .Joey bunker saline Louisiana
A lot of ingenuity on show here and actually, quality work. Respect
This is not quality work... This is shit. You can't build engines in the dirt and expect any longevity. Certainly would never pay for work done like this.
@@Herefornow-571 Yeah that's cool. When you're running a trucking company in Pakistan, your broken trucks can sit idle while you wait for a spotless shop to open. Secret hint: Working on heavy machinery is a dirty business. And yes you can do incredible things in all sorts of conditions if you're not a cry baby. You of all people should know. How do your Tiger tanks get fixed?
This shows how you can do it, dont get caught by the fancy bs shops, learn and take advantage of the modern facilities these people dont have. They are amazing people. God bless them.
Been lapping valves for damn near 50 years, and I've yet to find suction cups that work that well! :O

Machining by hand... Frickin beautiful job... Well done.
Incredible mechanics. Have hey not discovered work benches? So glad I don't live there. Yikes!!!

Much respect to these men!
Интересно сколько после такого ремонта походит мотор? Направляющие клапанов и сёдла клапанов сделали из того что попало под руку.
Its all they have got!!!!!!
Тысяч 20 пройдёт думаю)
Each man has a job, each has his tools, most seemed to be home made 'special tools' working by feel and sound, fantastic to watch
And then they threw it to the ground on the freshly machined surface...
Imagine a shop for building work benches!
It would make millions!
Na, these guys prefer squatting, many cultures do, if they wanted benches they would have benches.
With that pinning technique, is the bolt material have the same heat coiffecient of expansion with the engine head block? Otherwise if subjective to engine working temperature, there might be window for new crack or opening on that particular area.
I've seen stitching like this before, usually though they use iron pins to do the stitching not steel bolts, this was a common practice on large engines back in the day, pins would be mashed into place with an air chisel, think its the only way on cast iron parts as welding won't work.
@@andicog I was going to say wouldn't it be better to tig weld instead of steel bolts? I guess they don't have access to expensive equipment but they wouldn't make sense some of their decking machines gotta be expensive along with the lathes.
@@forg0tin397 Even engineering companies fixing the blocks from diesel locomotives use cold stitching, don't think its a cost issue, more the difficulty in welding cast iron successfully.
Cast iron has to be stitch welded. It’s nothing new
Watching these guys I get the impression that I could make a video on fixing a broken I- beam on a building using a propane torch and plumbing solder and people would say I'm a genius.
I respect their work in primitive shop,but my knees couldn't take one hour of that squatting!
If you had been doing it all your life it wouldn't be difficult
Have not yet discovered the use of workbenches… or protective gear… lol.

Too many people commenting on working conditions instead of appreciating the content. Most of us doing serious work use the floor as a workspace at some point or another. Doesn't matter whether it's to store something or mix concrete. So let's focus on learning rather than recommending how other people work.

Wow working on a rough floor. No shoes mostly, no safety glasses etc. But obviously they know what they're doing.
They keep things going we wouldn't bother with. Labour costs alone (mostly) determine a repair in North America. However they have a can do attitude and probably its affordable to their customers.

First comment. Amazing channel. Love it.
I would like to send them a work bench
They would probably take it home and use it to dine off of. They are comfortable working this way. My back hurts just watching them.
Its their way of working if not culture!
These cultures aren't, and I don't mean this in a bad way, like those of the modern world where we work at a table or even eat. They do everything on the floor, they spread a blanket or a sheet down and gather around with legs crossed while all the food is centered, in alot of cases even silverware is not used. There's a reason they write from right to left, unlike we in this comment section. I don't mean any of this in a bad way whatsoever, it's interesting how there's cultures out there different from ours and I'm fascinated by it.
Awesome work by awesome people 👍😊
