Use methanol. It will keep the cylinder head cool. They use NO coolant passages in methanol drag racers in the USA, because methanol cools so well, even 10,000hp racers.
You're thinking of top-fuel cars. The fuel is methanol + nitromethane, the nitro in particular has a large cooling effect due to its extremely rich optimal air:fuel ratio. They also run for only a few minutes at a time, and most of that is at idle (like 8 seconds WOT at most).
@@nerd1000ify No, I am not. Top Alcohol cars also use billet heads. Methanol has a latent heat of 473BTU/lb, while nitromethane has only 241BTU/lb. Methanol absorbs FAR FAR more heat per unit of mass than nitromethane fuel.
@@exploranator Wasn't aware that the straight methanol cara did this as well. I'd have to run the numbers to see exactly which one gets more overall cooling, nitromethane might have a lower latent heat of vapourisation but you do use a lot more of it per unit of air. In any case it's a bit moot, because drag engines are weird special cases. There's a lot you can do when you're only running under load for a few seconds at a time, and the engine gets a rebuild every few runs.
all you gotta do now is add the see through sump and you'll have an excellent teaching aid to young people to really show them how the intenal combustion engine works, what an amazing experiment. good stuff guys, love these types of experiment
So cool. The advantage of sidevalve engines is that it's possible to do this *relatively* easily as the head itself is mostly just a cover. In my opinion they also sound better.
Sidevalve/flathead design means low compression, which means low power. But it also means less stress on things so they last forever - there are still some engines from the 1910s/1920s still running today.
Here in the USA we call that type of engine a Flat Head Engine. In other countries they are called Side Valve Engine because the valves are on the side of the engine. I love Flat Head Engines. They are much simpler and that makes them more reliable. Performance is lower than an engine with overhead valves. Air flow is much better with overhead valves but I will take easy to work on and better reliably any day. The misfire on cylinder number 4 may be caused by carbon buildup in the intake port from a leaking intake valve. The misfire is not all the time so carbon is blocking air flow and absorbing fuel from the air/fuel mixture. Anyway, I really enjoyed this video! You guys are amazing at the things you come up with. I like working on Russian stuff. I helped restore captured Russian military equipment from Iraq at the Anniston Army Depot and I even have a KMZ Dnepr MT-11 Sidecar Motorcycle I restored a few years ago. I took it completely apart, inspected everything, and repaired or replaced bad part's installed at KMZ when the motorcycle was very poorly built by very poor workmanship. Today it's a good reliable motorcycle I ride often.
The misfire could be caused by many different things... Low compression, leaking valve, bad spark plug, bag ignition wire, carbon tracking in the distributor cap, and so on. It's not possible to tell by this video alone.
I can see this being a major advantage in scenarios where key parts of the engine experience failure. You'll be able to diagnose head gasket issues or valve float on the spot without removing the actual head or cover itself.
Maybe you could show what it looks like during a really cold start if at all possible? I'd be most interested in seeing this on a Diesel engine but i'd be really impressed if you manage to make a plexi head that doesn't instantly explode on those compressions 🤣🤣
The closest we’ll get is the fire pistons that warped perception made a video on. I think you could make a see through diesel if you had thick enough plexiglass with really strong reinforcement to prevent cracking.
I can personally attest that seeing a transmission valve body operate with a plexiglass cover plate is really something. When repairing a transmission on my Buick I had to cut test plates to run the valve body halves on a bench using a couple of pumps, cans of fluid and a lot of clear plastic tubing to take place of the interface plate. It was really something to behold when it all finally started to work, no amount of the couple hundred pages of repair manuals I had read up until then prepared me for what I seen at that point, it all just made sense. The gear train likely wouldn't be as interesting to see, some cool stuff goes on there but you would have to build things like the big drums and carriers out of clear materials too as they all have tiny channels for fluid to travel.
You can actually see that it needs more ignition timing because the ignition event is happening after the piston starts to travel down and the flame gets pushed out before it’s finished burning.
Maybe that’s even the problem why it’s not running anymore- the timing is going more and more off? You can see that it’s obviously still firing, but maybe it’s firing so late now that the piston is barely able to do any work?
It should fire near top at idle, then earlier as the distributor weights are pushed outwards at higher revs. And as for the flame being pushed out - the valve area is part of the combustion chamber, it should combust in there, it has to. Obviously you know it needs to be space there for the valves to open, the size/volume of that area has to be big and thats one of the weaknesses of flatheads, reducing the area gives better combustion but limits both valve size and opening and thus doesnt let the engine breathe.
I think an o-ring would work well. Just cut a groove ~.5mm deep around the combustion chamber ~1mm away, and run some ~.8mm wire in it to spread pressures & forces.
13:57 "Wow you really get a good view, when you have such a good view!" LOL 😂 love you Vlad! Also a side note that engine would have still started if it was a lada motor! 👏 happy new year!
I didn't read all 800 + comments so i'm sorry if this was stated already. I to noticed the exhaust valve opening up a bit sooner, pulling out the lit gasses. I wondered about that but then thought " man id like to actual Direct injection and engine knock taking place and leading up to pre ignition and detonation or what not!

I remember seeing these guys with rubber chickens for exhaust. They have defiantly gotten 307 percent more high tech. And from a guy that has had a love affair with the internal combustion engine for 30 years, this is the best video yet.

@@cudwieser3952 D.W. man your vocab is fine. I fully understood what you wrote. And I too, would love to see transparent engines acoss their evolution ranges. Nissan still does cutaways. Pretty sure they have an r35 vr38 cutaway on display @ their HQ in Jap.
Watching it in slo-mo gives me goosebumps, this is literally what humans made. The mechanics of engines is so simple, yet it took thousands of years for us to get here. And to see it all happen, is just plain inspirational. Harnessing chemical energy, turning it into kinetic energy. Thousands of mini explosions happening a minute, all near perfectly. And this is considered a basic engine, that many cars have. There is something about seeing all this that makes you feel in awe, to the science behind it, how we literally toy with physics, just to make commodity for day to day life. Crazy stuff man, truly crazy.
at around 10:35 Happiness is a universal emotion. This is one of the moment when you see his eyes and the excitement. I did not need the translator to convey the feeling and or the emotions. We men need only simple stuff.
Awesome! Watching the hot gases and flame get sucked into the exhaust was great. Would be cool to see a clear carburetor along with the clear cylinder head - to watch the fuel flow from start to finish.
Driving will always be different after seeing flame fronts and valve suction. And flooding! Now I wish I had a fiber optic camera feed from each cylinder to the dashboard computer screen.
@@MichaelLaferriere 😆 Exactly! There are small model engines available, with glass heads, so that one can sit and watch the combustion at the kitchen table if he wanted to. Definitely NOT while one is driving down the street.
It would be really cool to see a whole entire engine transparent. The block and all. It'd probably be extremely difficult to make, maybe even impossible. At least, for such an engine to run. But if you did you'd be able to see the crank, pistons and connecting rods, valvetrain, etc etc. Would be even cooler on an overhead cam engine, or a bigger one two, like a V6 or V8 or something. Again, would be extremely hard or even impossible for an engine built like that to run, but man would it be cool to see
They make some pretty cool models today. I have a half size ford V8 that sparks and runs on vegetable oil for the oil. It costs a lot but it's really cool and you learn exactly how it all goes together, every piece, nut and bolt.
It could be made with todays material, aluminum oxynitride aka transparent aluminium. Its ceramic stuff, harder than steel. Too expensive to be realistic though.
something I didn't know I wanted to see!!! this is a regular on your channel!!! Thanks for showing the world all the stuff we would never see anywhere else!! Happy New Year!!
Happy new year! I have been watching you guys for so long! amazing to see how far you've come! would be amazing to see a tempered glass cylinder head someday
If i were to ever visit Russia, i think you guys would be my first stop jsut to say hello and thank you for the content. as for a clear item suggestion, how about a clear waterpump assembly? a clear radiator, clear freeze plugs to monitor in the coolant jackets? clear hoses.
This is exactly why it's horrible to run an engine extremely rich all the time. The extra fuel washes out the cylinder bores, and wear occurs very fast. Pretty soon the rings would be shot, and there will be no compression left.
@@irgant rubber or silicone head gaskets and such would squish first. But one bolt tightened more than another would likely break it, so each bolt would have to be tightened a quarter turn at a time.
@@markae0 What engines use rubber or silicone head gaskets? None. The common head gasket material used today is M.L.S. (multi-layered steel). It hardly compresses at all, and good practice to torqueing head gaskets IS in a pattern, and in small steps on each bolt. Ford had "glass" heads on one of it's running flathead V-8 engines way back in the 50's. So yes, it's completely possible to do it today.
Definitely be interesting to see what colour flame you get, and if flow's any different with different gases. You could try petrol vapour too, like the whole Pogue Carburettor thing. Then, if you're gonna destroy it, there's always good old laughing gas!
That's how you learn that edges in tge combustion chamber cause hot spots, knock.... That's one big reason for low power old engines, amon many others. Great video
Sure it would be possible. But besides just curing the "melting" issue, this would bring on a host of other problems because glass is a much poorer conductor of heat, compared to a proper metallic head.
Probably, by what I see, spark event is not timed right. Distributor is wiggling all around. Try to run Diesel through the carb and see what kind of timing is needed to get running without excessive pre-ignition. I did this with a small 2 stroke and 4 stroke motorbike engine, and it worked. Since the default low compression ratio won't set it off on it's own, you can mill the "Plexi-Head" flat to bump ratio...but making it flat would moreso make rebuilding this engine for other runs easier/quicker/cheaper. Good job Garage54!
I miss my old side valve engined Ford. There's something about being able to take the cylinder head off in five minutes that is quite endearing. Never even needed to fit a new head gasket, because there is nothing mechanically pushing it off like on a new fangled OHV engine and no oil-ways.
Nothing "mechanically pushes the head off" on an OHV engine either. 🤔🤷🏻 Flat heads are severely limited in power and efficiency by the horrible intake and exhaust ports, and the low compression they are stuck with. They are a poor design, and I'm GLAD to be past them.
@@skylinefever This applies to a flathead also, if one wants to try and increase power. It's called cylinder pressure, and all engines, even flatheads, create power from it. If you want to live with a weak and inefficient engine, then use a flathead
That is SO COOL. I've seen videos of single cylinder engines with transparent heads, but never one of an engine with more than one cylinder. Instant like from me.
The plexi allows you to run a higher compression ratio by drilling away less material and having a smaller combustion chamber. I'd like to see that as another experiment with this engine.
Это круто! У вас, ребята, невероятные навыки, как у мастеров. Мы больше не видим этот тип навыков в Америке, потому что все автоматизировано. Я рад видеть, что люди до сих пор работают руками. Отличный друг по видео, спасибо.
Thanks for another cool clip, great work on clear cylinder head! Only at 54! I received G54 air freshener the other day, smell great! Thanks heaps, will order more stuff when I save up, cheers from Australia maytes!
"Wow you really get a good view when you have such a good view" 😂 I am at a loss for descriptive words too as yeah 😲that was AWESOME! to see. Thank You Garage54 for bringing these crazy ideas to life & BMI for the excellent translations so us in the English speaking world can enjoy them too 🥰Poka!
Yah , I think those old flatties were only about 7:1 compression , so I think the melting in the combustion chambers lowered it down to probably less than 5:1 . But that was how I always pictured it . you could even scan the 1-3-4-2 firing order . Damn you guys did a beautiful job on the combustion chambers . Nice work guys . :)
A Moskvitch 401 (1947-55) originally had only 24 bhp/3400 rpm on 1074 c.c. and only 5.8:1 compression...if you had strong enough vodka it would run on it!
@@vitameat Our flathead had a touch more compression , except the tractor motors , but those were smooth running little buggers . I'm an old iron kind a guy . Lol
Absolutely why I keep watching you guys!! One time your making some crazy spacer or slinging tires, the next your doing something that's truly "educational"😉! Love it!
Beautiful , such a masterpiece . And you are right , I could just watch the combustion inside the engine. It's a very great educational video for future mechanics. thank you for making this video.
Had to pause. Thought that engine looked familiar. Sterling kit has a tiny 4cyl engine exactly like that! Runs too! FL4-175 Flathead. No bigger than a cigarette! They have another 4cyl that has an ohv setup instead of the valves sitting next to the piston. JohnnyQ90 has videos of them running! Again very cool!
I don't comment every on your channel. I'm a silent viewer. I like this video. I have watched almost every video you have produced. I live in Lexington Kentucky. Thankyou.
Very interesting to see this has 1-3-4-2 firing sequence, unlike the typical Russian 1-2-4-3 of that era. Also glad the engine refused to start in the end for the destruction run, it's a perfect example of a old engine getting wise, knowing when to work, not take any abuse or crap.
That is so friggin Kool Garage 54. It looks like the engine stopped then the plug fires and the engine spins back up. (Edit) even not running it still looks awesome when it fires.
Does not get any better than this comedy and a learning achievement worked on a lot of flat heads but I never had a chance to see a see-through head one excellent Vlad....
Clear head for a flat head head 4!?! Niiice! To get the clear plastic as polished as possible, use a very soft buffing wheel on a fast rotary tool with some 1200 diamond grit lapping compound. Great results! Also brings back those hard to fix headlights. Great video and happy new year!!!

@@gabrielv.4358 ... oh, you absolutely can float the valves on a flathead engine.... but they won't hit the pistons.
@@rupe53 thats what I meant to say
Here in the USA we call that type of engine a Flat Head Engine. In other countries they are called Side Valve Engine because the valves are on the side of the engine. I love Flat Head Engines. They are much simpler and that makes them more reliable. Performance is lower than an engine with overhead valves. Air flow is much better with overhead valves but I will take easy to work on and better reliably any day. The misfire on cylinder number 4 may be caused by carbon buildup in the intake port from a leaking intake valve. The misfire is not all the time so carbon is blocking air flow and absorbing fuel from the air/fuel mixture.

Well, this is like Warped Perception's transparent head videos, but on another awesome level! Great job guys. Yes you should try other fuels.
Great Video. When the plexi gets hot and begins to melt, the fumes throw the air mixture off so it wouldnt run the 2nd attempt.

Harnessing chemical energy, turning it into kinetic energy. Thousands of mini explosions happening a minute, all near perfectly. And this is considered a basic engine, that many cars have.
There is something about seeing all this that makes you feel in awe, to the science behind it, how we literally toy with physics, just to make commodity for day to day life.
Crazy stuff man, truly crazy.
This is amazing!
I cant wait to see if you can make a full transparent engine. That would be a world first!
Edit: Happy new year!
A few weeks ago someone posted a video of a transparent single cylinder engine running on you tube.
Edit. A transparent cylinder on an engine.
at around 10:35 Happiness is a universal emotion. This is one of the moment when you see his eyes and the excitement. I did not need the translator to convey the feeling and or the emotions. We men need only simple stuff.
Awesome! Watching the hot gases and flame get sucked into the exhaust was great. Would be cool to see a clear carburetor along with the clear cylinder head - to watch the fuel flow from start to finish.
35 years as an Automotive technician and this is the most awesome thing I have ever seen :)
Driving will always be different after seeing flame fronts and valve suction. And flooding!
Now I wish I had a fiber optic camera feed from each cylinder to the dashboard computer screen.
Watch the road! ;-)
@@MichaelLaferriere 😆 Exactly!
There are small model engines available, with glass heads, so that one can sit and watch the combustion at the kitchen table if he wanted to. Definitely NOT while one is driving down the street.
Amazing video perfect for mechanic students to watch and learn how a four stroke works thank you
Garage 54 very well done !
Some big washers on the top would've helped, and tightening down the head after it got good-n-warm would've helped also, thanks for sharing guys.
It looks like there was no head gasket too. I think the air was coming through the cracks between the engine block and plexiglass.
I remember the 1953 auto show in New York when Ford ran a flathead V8 with Pyrex cylinder heads. Awesome job guys!
It would be really cool to see a whole entire engine transparent. The block and all. It'd probably be extremely difficult to make, maybe even impossible. At least, for such an engine to run. But if you did you'd be able to see the crank, pistons and connecting rods, valvetrain, etc etc. Would be even cooler on an overhead cam engine, or a bigger one two, like a V6 or V8 or something. Again, would be extremely hard or even impossible for an engine built like that to run, but man would it be cool to see
Maybe with future materials.....
They make some pretty cool models today. I have a half size ford V8 that sparks and runs on vegetable oil for the oil. It costs a lot but it's really cool and you learn exactly how it all goes together, every piece, nut and bolt.
It could be made with todays material, aluminum oxynitride aka transparent aluminium. Its ceramic stuff, harder than steel. Too expensive to be realistic though.
We need some of that Star Trek transparent aluminium.
the engine looks so neat!
old moskvich engine bays look so.... clean and beautiful
Seeing how the combustion works is amazing and even when you flooded it
something I didn't know I wanted to see!!! this is a regular on your channel!!! Thanks for showing the world all the stuff we would never see anywhere else!! Happy New Year!!
Happy new year! I have been watching you guys for so long! amazing to see how far you've come! would be amazing to see a tempered glass cylinder head someday
How has this only got half a million views, this was really special. Loved it. Amazing video!
reminds me of the Warped Perception see-thru cylinder head!
I wasn't excited at the thought of seeing the 4 strokes but boy was I underestimating its beauty. It is so great to look at. wow.
If i were to ever visit Russia, i think you guys would be my first stop jsut to say hello and thank you for the content.
as for a clear item suggestion, how about a clear waterpump assembly? a clear radiator, clear freeze plugs to monitor in the coolant jackets? clear hoses.
This is about the best ever clear top i have seen on an engine. Well done. You should totally get in touch with slo-mo guys Lol. This is brilliant.
Very cool, especially when you flooded the engine. You could see the gasoline washing the oil off the combustion chamber.
This is exactly why it's horrible to run an engine extremely rich all the time. The extra fuel washes out the cylinder bores, and wear occurs very fast. Pretty soon the rings would be shot, and there will be no compression left.
From 12:04... Goosebumps😁😁 🤩🤩🤩😍😍. Absolutely mesmerizing!!!
Try making a water cooled transparent cylinder head out of thick tempered glass or something that won't burn as much
Since they have the original, get it cast in Pyrex or Quartz. Maybe metal inserts for spark plugs and bolt holes
Might be hard to form the glass around the cores you'd make, the viscosity of molten glass is pretty high
@@thesilentcitadel If you cast it in quartz, it IS glass.
@@irgant rubber or silicone head gaskets and such would squish first. But one bolt tightened more than another would likely break it, so each bolt would have to be tightened a quarter turn at a time.
@@markae0 What engines use rubber or silicone head gaskets? None. The common head gasket material used today is M.L.S. (multi-layered steel). It hardly compresses at all, and good practice to torqueing head gaskets IS in a pattern, and in small steps on each bolt. Ford had "glass" heads on one of it's running flathead V-8 engines way back in the 50's. So yes, it's completely possible to do it today.
👍 This was great! The old flat head engines are classic, and it was fascinating to watch it run through the transparent head.
Definitely be interesting to see what colour flame you get, and if flow's any different with different gases. You could try petrol vapour too, like the whole Pogue Carburettor thing.
Then, if you're gonna destroy it, there's always good old laughing gas!
Laughing gas? You mean oxy-acetilene? Lol
He was from my city!!
@@eljaibas16 nitrous oxide is also laughing gas
That's how you learn that edges in tge combustion chamber cause hot spots, knock.... That's one big reason for low power old engines, amon many others. Great video
I would like to see a head made of high temp glass so it doesn't melt. I wonder if it possible?
If someone can cut that complex shape it should
@@GeorgiGeorgiev-ne9ps Or cast.
I think they used plexiglass because regular glass would be too brittle
Sure it would be possible. But besides just curing the "melting" issue, this would bring on a host of other problems because glass is a much poorer conductor of heat, compared to a proper metallic head.
Probably, by what I see, spark event is not timed right. Distributor is wiggling all around. Try to run Diesel through the carb and see what kind of timing is needed to get running without excessive pre-ignition. I did this with a small 2 stroke and 4 stroke motorbike engine, and it worked. Since the default low compression ratio won't set it off on it's own, you can mill the "Plexi-Head" flat to bump ratio...but making it flat would moreso make rebuilding this engine for other runs easier/quicker/cheaper. Good job Garage54!
That "primitive" cylinder head is a classic flat head design. Like the famous Ford flat head V8s
This is honestly the best thing I have seen all year!
I miss my old side valve engined Ford. There's something about being able to take the cylinder head off in five minutes that is quite endearing. Never even needed to fit a new head gasket, because there is nothing mechanically pushing it off like on a new fangled OHV engine and no oil-ways.
It also helped to have so many studs holding the head in place and 6.5:1 compression.
There's something alright...near zero flow and horrible cylinder dynamics.
Nothing "mechanically pushes the head off" on an OHV engine either. 🤔🤷🏻
Flat heads are severely limited in power and efficiency by the horrible intake and exhaust ports, and the low compression they are stuck with. They are a poor design, and I'm GLAD to be past them.
@@davelowets Compression ratio and (When applicable) boost pressure pushes the head upward, whether the engine is a flathead, OHV, or OHC.
@@skylinefever This applies to a flathead also, if one wants to try and increase power. It's called cylinder pressure, and all engines, even flatheads, create power from it. If you want to live with a weak and inefficient engine, then use a flathead
That is SO COOL. I've seen videos of single cylinder engines with transparent heads, but never one of an engine with more than one cylinder. Instant like from me.
The plexi allows you to run a higher compression ratio by drilling away less material and having a smaller combustion chamber. I'd like to see that as another experiment with this engine.
More compression = more heat though :(
Happy new year Garage 54! Thanks for all the work you's do!
Это круто! У вас, ребята, невероятные навыки, как у мастеров. Мы больше не видим этот тип навыков в Америке, потому что все автоматизировано. Я рад видеть, что люди до сих пор работают руками. Отличный друг по видео, спасибо.
Thanks for another cool clip, great work on clear cylinder head! Only at 54! I received G54 air freshener the other day, smell great! Thanks heaps, will order more stuff when I save up, cheers from Australia maytes!
Transparent 4 cylinder
Nice! 😃
- propane
- ethanol
- isopropyl alcohol
- acetone
- xylol
- industrial cleaner (a mixture of the last 3)
Here in the US, that's called a "flat head" engine.
Or a "side valve"... I've heard BOTH used often here in the U.S.
That is freaking cool to watch!👌😂👍this guy’s amaze me every time!😂👍happy new year garage54!
Garage 54: TRANSPARENCY!!!!
Vladimir Putin: EXCUSE ME?!?!
"Wow you really get a good view when you have such a good view" 😂
I am at a loss for descriptive words too as yeah 😲that was AWESOME! to see.
Thank You Garage54 for bringing these crazy ideas to life & BMI for the excellent translations so us in the English speaking world can enjoy them too 🥰Poka!
Omg
Yah , I think those old flatties were only about 7:1 compression , so I think the melting in the combustion chambers lowered it down to probably less than 5:1 . But that was how I always pictured it . you could even scan the 1-3-4-2 firing order . Damn you guys did a beautiful job on the combustion chambers . Nice work guys . :)
A Moskvitch 401 (1947-55) originally had only 24 bhp/3400 rpm on 1074 c.c.
and only 5.8:1 compression...if you had strong enough vodka it would run on it!
@@vitameat Our flathead had a touch more compression , except the tractor motors , but those were smooth running little buggers . I'm an old iron kind a guy . Lol
This is a cool idea! Actually seeing the engine firing!!!!! Glad you had a flathead engine to use!!!
straight to the point as always, love it!
Feliz 2022 Garage 54!!! Desde Buenos Aires, Argentina.
This might be the coolest thing you guys have done so far. Absolutely incredible footage from the engine running.
Absolutely why I keep watching you guys!! One time your making some crazy spacer or slinging tires, the next your doing something that's truly "educational"😉! Love it!
You showed what an engine enthusiasts always dreamed of! Great as usual!
Nice! First multi cylinder see through head!
Great work on that head! Looked great, too bad all that polishing dosen't last forever :)
Beautiful , such a masterpiece . And you are right , I could just watch the combustion inside the engine. It's a very great educational video for future mechanics. thank you for making this video.
Yes mesmerizing , and yes I seen the Exhaust being drawn-out very cool nice work !
Now THAT is the goods! I love how you can follow the orange power strokes from cylinder to cylinder.
Had to pause. Thought that engine looked familiar. Sterling kit has a tiny 4cyl engine exactly like that! Runs too! FL4-175 Flathead. No bigger than a cigarette! They have another 4cyl that has an ohv setup instead of the valves sitting next to the piston. JohnnyQ90 has videos of them running! Again very cool!
You guys are the best, I’m a big fan from 🇺🇸
Amazing video, i watched many videos with transparent cylinderhead and this video is the best, much better than overs.
I was waiting for the plexi glass to burst but it didn't. Plexi glasses are indeed pretty tough. Great video, guys!
What a brilliant video, happy new year to Vlad and co, and well done for showing us this, the slow motion was excellent.
I don't comment every on your channel. I'm a silent viewer. I like this video. I have watched almost every video you have produced. I live in Lexington Kentucky. Thankyou.
This reminds me of the old as the hills "color tune" spark plug testers, just an engine head.
Finally somebody does it to a multi-cylinder flathead that was awesome
Very interesting to see this has 1-3-4-2 firing sequence, unlike the typical Russian 1-2-4-3 of that era. Also glad the engine refused to start in the end for the destruction run, it's a perfect example of a old engine getting wise, knowing when to work, not take any abuse or crap.
Happy New Year!! 🎉🎊🇺🇸
Sooooo Cooool!!!!! Wow that was just incredible. Thank you so much for making this and sharing it. Cheers.
The slow motion is so satisfying. Air and fuel get sucked in. And the explosion get forced out. It's so cool 😎 🤯
Nice...its the SLO-Mo which really helps understanding.
That is so friggin Kool Garage 54. It looks like the engine stopped then the plug fires and the engine spins back up. (Edit) even not running it still looks awesome when it fires.
love the slow mo footage
Does not get any better than this comedy and a learning achievement worked on a lot of flat heads but I never had a chance to see a see-through head one excellent Vlad....
We love you guys!!!!!
Greetings from Greece!!!
You are the most skilled mechanical engineers i've ever seen, or at least you are real artists! Thanks for this Xmas present
Message from the US keep up the great work I've never seen such a cool video like this
Clear head for a flat head head 4!?! Niiice! To get the clear plastic as polished as possible, use a very soft buffing wheel on a fast rotary tool with some 1200 diamond grit lapping compound. Great results! Also brings back those hard to fix headlights. Great video and happy new year!!!
