We watch an engine run through a transparent cylinder head

In this episode we have a look inside a motor while it's running.

You and your shop are the legitimate A-Team....there truly isn't a thing y'all can't accomplish. Grade A video guys.

Out of all the goofy, weird, funny experiments you guys have done over the last couple of years, this one ranks as probably the most accidentally educational. We all know what happens, but to be able to watch it happen is a whole 'nother level of fascination. I was really impressed that you got the plexi head machined as well as you did, never mind making it work. Really 107% success rate on this one.

BTW, Vlad, that type of engine is simply called a flathead.

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

[CaptHollister]

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.

[exploranator]

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.

[Imnotyourdoormat]

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.

[Nordern]

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 🤣🤣

[Fidelis]

Well, this is like Warped Perception's transparent head videos, but on another awesome level! Great job guys. Yes you should try other fuels.

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.

Never seen a 4 cylinder with transparent head. Nice job guys!

[TheSilverShadow]

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.

[Jeesus]

This is the coolest project hands down. Was amazing seeing the pistons working.

[Donjo]

Love your garages imagination and ingenuity along with the skills and talent to make them come alive. The excitement is also contagious.
Great work.

[ozielsolis]

It be awesome to see a transparent transmission shifting gears

[Fktd]

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.

[Iowa]

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.

[thatsgottahurt]

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.

[yogidemis]

Vlad & crew are doing things that I always wondered about. Keep up the great work men!!

[trogdorburninator]

Best wishes to the ‘54 family for the new year!

Best video I have ever seen on this channel.
Very cool.
