Thanks to Koneistus Alho for letting us film their diesel engine mayhem! As said on the video we order quite much smaller parts and larger patches from them that we don't have suitable machines for on our own workshop and I can strongly recommend them. Check their machines and services from their websites if you need high quality machining in Tampere area www.koneistusalho.fi/ And for people that worry that it was some really rare historic engine, no need to worry these are super common and not rare in Finland and they still have a LOT of nicer engines like this to play with.

That old engine ran really well for its age. It made me sad to see it die like that.

That engine is way too powerfull. It's falling apart, on fire and probably melting down but still keeps on running like it's usual day for it.

Whoever built that thing was a master mechanic. Back when things were really built to last, we live in a disposable world now.

I was kind of bummed to see such a cool old diesel go like that, but after looking at the flywheels, there's like a quarter inch of runout lol😂. That thing didn't have more than a couple days worth of operation before the journals/bearings turned to playdough. Looks like it took a really hard hit to bend the main shaft that bad. Engines aren't supposed to shake themselves to death even in a runaway condition lol. The shaking was from the flywheel's insane runout...

Finnish space program looks good

That hurt the mechanic soul in me. Poor little bugger, to be abused like that… O.0

That engine looked ancient, but this is definitely a testament to whom ever engineered and built this thing.

OMG that breaks my heart to see that little booger be treated so badly .

That poor engine, such a will to live 😭😭😭😭

These were engines built to last lol. Basically all old two stroke diesels are nearly unkillable, somehow sad to watch it getting destroyed but also quite interesting :D

Kudos to the people who designed and built this engine. If your design can survive and more importantly not kill anyone even after everything has gone wrong its pretty great.

Brings a tear to the eye this does.

There's something sad, even melancholy, about seeing it on fire and literally running itself into pieces, but still running hard anyway, even to the point of self-destruction.

As an old engine collector and enthusiast, this makes me very sad.

Man have a heart, I would die to have one of those.

That was just depressing to watch a beautiful antique engine, likely 100 years old, and still running, being destroyed like that.

"Whiskey, thins down the mix! Gives us another 50 RPM!" - Howard, 'Down Periscope', while adding whiskey to a WWII submarine's oil.

*Diesel Engine Manufacturers:* Noooo you can't surpass the max speed with tierip bands, it will catch fire and explode!!! *Anni & Lauri:* Haha Diesel Engine goes brrrrrrrrrr

"Don't try this at home. This is stupid." Best advice yet.

At the end, it almost like the little engine wanted to say "I'm sorry, I can't run no more boss. I broke. But did I do good today? Will I get some fuel and oil now? Will you clean me an repair me so I can work for you forever? Boss?...... Boss, are you there....?" So sad :\

Another fun way to destroy a diesel engine is to dump a halon fire-extinguisher into the intake. Halon will break down under the compression, and the gasses it makes expand quite a lot...drives the engine like super-charged fuel! Not only that, the halogens it makes are fairly toxic and very corrosive to metals. My brother was designing 'packaged power' units; a shipping container with generator set, controls and fuel tanks for providing power where needed. The things needed fire suppression, and nobody knew at the time that halon and diesel is a bad mix. They had a big demonstration test of the fire control system; lost a very expensive brand new engine. In front of customers!

I've only seen a runaway diesel in person once. A neighbor who liked to work on cars dragged home this ancient Mercedes sedan. He finally got it running, and it just took off. We came outside just in time to see him jump into the car and try to stop it by holding the brakes and putting it in gear, but all that did was blow out the clutch. It ran for maybe another 10 minutes before something did explode. Quite a show.

For a lifetime of loving old engines that was very sad to watch.

Definitely shows how strong those old school engines really are.

"I declare that this is a successful failure."

Everyone complqining about the destroying this engine should know that this specific engine is super common in scandinavia.

For its age, its quite amazing how long it survived

"... and don't try this at home, this is stupid." Love you guys, thumbs waaay up! Thanks a lot with big smile on face.

That machine lasted so long despite the abuse thrown at it, testament to quality Volvo Swedish engineering!!

A dislike for destroying a 75+ year old treasure.

She's just needs a new top end rebuild. She'll be fine.

I'd love to see a car engine explode at full revs.... Now that would be fun

Yes, thats how I imagine Dieselpunk Battle Mechs fighting - "Limiters off men, last one push!"

I kinda feel like I just watched a great work of art being destroyed.

These old semi-diesels can run for ever! I like to see a full restoration of this engine

Things where over engineered back then, with a long stroke like that the piston speed and acceleration must have been frightening. Something serious and reciprocating gave out as early as 3:20 but it just kept going. A strip down would be interesting.

The little engine that could - May it Rust In Peace :)

I love that you guys have a pure channel with very little emphasis of self worship and more a worship of life and all of its beautiful perks.

This little engine survived a lot of time for this insane abuse and for the age and the probably thousand of hours it ran in the passt just incredible.

Those engine revs. That's how most people were driving when they heard the pubs were open after lockdown

This 100 years old 2 stroke engine is still lot safer than a self-destroying BMW N47D20.

pretty impressive to see how those old machines are so well built

that engine, on fire, rattling itself to pieces but somehow still going, is how I feel all the time

Man I need one of those badly! To generate electricity for my home. Those things run forever!

"quite far away" 6:50 Must be a trick of perspective haha

That proud old engine fought its torturers every step of the way.

We live in a world where it more profitably to destroy something on youtube rather then to refurbish such a wonderful motor for resale

I see the Amon Amarth T-shirt \m/

When the engine catches fire, you get automatically +20% horsepower.

I bet hot bulb engines will have a renaissance. When people want to live off grid and still have the comfort of electricity this is one beautiful power source. Runs on anything that burns almost.

Wow can't belive they let you do this to an old engine!! This is something I've always wanted to watch!! Thank you!!

6:48 when your buddy wants to show you his sick new vape

That helpful little machine didn't deserve its end.

Why would you want to kill such a cool old engine??? It's an antique 😭

Dang that diesel engine did not mess around. Was all weather worn but still worked hard!

There's something almost kind of darkly sci-fi about an engine intentionally running beyond all safety parameters just to destroy itself on purpose. I love this video, like all the rest you folks do.

Rip vintage engine😥

My highest respect to the constructors of this machine! They did their best to make it idiot-proof.

Ah, a beautiful end for an incredible piece of machinery.

Try that on a 2 stroke next.. Rpm untill the piston shoots through the head(2 stroke gas engine)

I love the sound of old engines like that. Especially when they run out of control.

It's kinda amazing what punishment an old diesel engine can take and just keep on going.

Original manufacturers of that engine would probably be proud and pained to see such insane rpm (and for what it is, insane power) lasting that long out of their old machine

I am impressed how long it ran while on fire!

Old engines are very cool. It's sad to see one get destroyed. 😔

First time in my life a movie made me cry 😭😭😭

I spend most of my time learning and figuring out how to keep an engine running longer. Then there's you guys. 😂

I have to say, that engine is tough!!!!

"Aaand... That should make it go mad!" Yep! Seems pretty mad to me. xD

*Greta Thunberg wants a word with you* "How dare you" 🤣🤣🤣

Ha ha! I actually started leaning back when it ramped up that first time🤣.

RIP nice engine.

shame to see such an old engine destroyed but who can say no to carnage caught on film LOL

X-Haust Seriously tho. That thing looked like it belongs in a museum lol. Some people might consider that desecrating artifacts lol

LOL, I knew you'd be catching some flak from the antique engine aficionados on this one!😆 Can you imagine how fast a Lanz Bulldog could go, if you could wind it up like this?🤣 I'm kind of surprised it didn't send a connecting rod through the side. The iron pistons in those engines are *HEAVY!* 😁

That engine deserves a Medal for performance. An old motor like that taking an incredible amount of abuse. If you try that with an engine made from today the video would be much shorter and no Medal.

I’d love to have owned that engine.

I’ve never seen a crank shaft bend that badly before the con rod fails

Wow old engines are just amazing. They're maybe not the most efficient but they sure can keep on working when other newer stuffs already fail.

Poor machine! She didn´t deserve such an end! 😔😔😔

Modern engine if a fly farts in the vicinity of the fuel tank: "Hnng! I die..." Ancient scrap engine being fed death-fuel: "Bah! I'll take it, and ask for more!"

its the little engine that could... ...until it couldn’t. nice vid! cheers!!

That thing ran extremely well for it's age, it made me sad see it gets destroyed

We used to have mini-bikes with 3.5HP engines. Of course we always disabled the speed governor :-)

Restoration on this fine old engine would have been more enjoyable.

Enjoyed the video alot. I think if you found a cheap 4 stroke engine and routed an oil line with some sort of injection nozzle with some sort of pump and a valve into the air intake you would be able to simulate it better since a two stroke engine is designed to run on oil. A 4 stroke engine would run quicker and cause alot more carnage. As for the smoking issue with a 4 stroke make a long exhaust pipe that vents away from the engine a ways to help alleviate some of that problem. Food for thought. Thanks for the video once again

This was a great video. I really like y'all's hats.

Such a shame, needless destruction of a nice old hot bulb engine, another bit of history condemned to a slow boat the melting pots

For a rubbish old engine it certainly put up a gallant performance.👍😷🤔 Cheers from 🇦🇺 Australia

I couldn't even watch this, this engine is a unique relic that should have been preserved in a museum, not blown to bits

Love the videos, carry on !!!!

I remember a tale of Yanmar testing one of their single cylinder engines by jamming the governor and revving the nuts off it. The crankshaft snapped and the flywheel, a very heavy flywheel, went for a little walk through the bunker wall. Hell of a lot of energy stored in an over speed flywheel!

3:53 "We decided to try again and add more oil, and even like... more more oil." Wow. That's a lot of oil!

man i actually dream of having an old engine like that to use with a generator offgrid near the lake.

Don't worry I wouldn't try something so stupid at home I have respect for that old iron

This is a cruel thing to do to a magnificent old engine. Like whipping an old plow-horse to death.

Run away diesel engines are scary things.

That was a great old engine, if it was run as it should have been, it would have out lasted a lot of the newer stuff we get today. A great video, thank you for posting.

this is what thomas and his friends do to diesels at 3 AM
