I love how the guy with the red golf just slams the hood like "okay little shit go for what you need to do imma head out"
He just accepted it. At that point the engine is doomed anyways, with it knocking and over-revving
@@danishghostrider he couldve just dumped the clutch in high gear
I wonder if a "Halon type " of extinguisher shot into the air intake would stop the combustion process, with no damage to the engine. I think so.
You can do something about it
@@danielcalhoun8850 what?
For those of you that don't understand about Diesel's running away, you can turn the key off all day long but engine will not shut off. Once it has an outside fuel source it will run continuously. The only way to shut off a runaway diesel is to jam something in the air inlet so it chokes it out.
Fire extinguisher at intake.
@@raymondholguin7272 that would work too, but I wouldn't use the powder ones I try to find a CO2 one.
some modern diesels have a valve that looks like a throttle body that closes when ignition is off. normally used to prevent a hard shake when you turn off the engine, but also cuts air preventing runaway if necessary. one example is the IZUZU design Z17DTH
@@mikecurzio7312 I heard a phone book at air filter also. I'm sure what ever you can find is the answer lol.
can also put it in high gear, hold the brakes and ease off the clutch to forcibly stop the engine... if you have a manual transmission
What gets me is how many diesel engine operators do not know how to shut it off if it runs away.
Block the air intake !
Some two stroke diesels are actually shutoff by that method exclusively (owned a farm tractor that you pulled a handle to kill it). Many buses that had two stroke had a backup kill switch. There is a less frequent phenomenon that a diesel can do and that is run backward...had it happen to me once and I shut it down and it restarted fine.

4:06 bro got george floyd on his car lmao
Ironic
Car overdosed
@@BuddyTheWolfYTmore like iconic
George Floyd couldnt get enough air and the diesel is getting too much air
@@BuddyTheWolfYT yeah .as in they both o.d.
2:54 bro just had enough already😂
"fuck this car man..." lmao
Can you imagine the absolute carnage the truck at 1:54 would have caused if not attached to the sled?
Bro was trynga make babies with the dyno.
Like a beast on a leash!
I'm actually impressed by the engine on that rotavator (or whatever it was) at 7:00. I can't imagine its normal operating rpm is a tenth of what it reached there.
Yeah that was the best one, it sounded like a two-stroke dirt bike there for a second 🤣🤣🤣🤣
It revved some 11k RPM, for sure.
"Thomas had never seen such RPM`s before"
Me too. I was very surprised it didn't sling its rods through the block. It had to be a well made engine.
Definitely a well made beast of an engine to withstand that.
Keep reading people sayin you kill it with covering with rag but due to the runaway it has so much suction it could take your hand. Whatever you block the intake with, don't let it be you.
I once had a vintage diesel tractor run away. I attempted to choke it out with a block of wood. It kept running as if were an airfilter. Only dumping the clutch worked with brakes fully engaged. Regardless of how and why, scary stuff
Yes use a rag or whatever but hold it on with a board, or even a large piece of cardboard. Just whatever it is you use make sure there's a solid physical block between you and your choice of item for smothering it.
7:12 Did't knew that this could rev THAT high
most likely just sounds like it is revving high due to its engine design. Its a diesel lawnmower i doubt it makes 8000 rpm.
It was a 2 stroke engine. So naturally they are going to sound really fast.
Sure, lots of engines can go very high. It's just that they can only do it once.
@@sugoruyo well its more so surprising how it held up at that high of an rpm. Most engines nowadays (in cars) will lock up if going above the redline pretty fast if its riding there somehow.
For anyone curious, the roto tiller or whatever it is at 6:50, assuming it is a single cylinder two-stroke, reached a peak rpm of about 5600 rpm. It sounds so much higher because we are used to the sound of four-stroke engines, which would spin at 11200rpm, but in fact it is only half of that. Still pretty impressive for a piece of antique farm equipment
I don't think it's a two stroke diesel
I had a 1.2 L Daihatsu diesel run away on me and I ran away, knowing there would be an imminent implosion 😅 3 mins later, Boom 💥 😂
How funny is that one with Big Floyd, go from "i cant breathe" to "please choke me" 🤣
Typically its the turbo oil seals that let engine oil into the pots via the inlet maifolds.It burns the same as diesel under compression and heat within the head.At this point even if you turn the engine "off" ie cutting diesel fuel it is at this point now just running off the oil leaking past the turbo compressor seals.You can only stop this by choking the air intake.Under high heat engine oil will actually detonate easier than diesel fuel and start to then draw in more air through the intake and runaway until the engine lets go.Thats why you get the thick black smoke as oil burns blacker and an engine that revs itself higher and higher perpetually.
okay. Share the solution to avoid run away. DRILL A SMALL HOLE (3/32 inch) under the air cooler. This will let out the accumulated oil inside the cooler. Don't worry about drilling. it will not cause a problem, it will be a small air leak. The turbocharged intake system has positive air pressure at all times. If there is an oil leak through the hole (drilled) you will be avoiding the run away. If no oil comes out, it means turbo in good condition. No need to worry! the hole made can remain, it does not represent a problem. it will even avoid the run away. It will act as a damaged turbo indicator
I can't quit laughing at the first one, dudes getting whiplash in that truck 🤣🤣🤣
7:36 WOW, SOUNDS LIKE 12,000RPM!!!! THAT IS CRAZY HIGH FOR A DIESEL ENGINE!!! Even higher RPM than a tuned Predator 212cc for SURE!!!!
That was a two stroke on that thing. Naturally 2 strokes will sound really fast. It was probably running about 6k.
puts rotaries to shame!
By the way, that was a german dude saying "oh shit" at the end...
Had no idea this was a thing. Very educational! The very first clip is easily the scariest example. It practically ripped that poor truck apart.
Whilst it is scary, in every day vehicles it's not as violent. Yes the engine will destroy itself if nothing is done. But if you're in the car it will not shake you around as violently.
This was a tractor pulling vehicle obviously, so it has a wee bit more power than your average f150
Theres another camera angle of the first one that shows a lot more. The truck was literally ripped apart lol
Oh my bad I should've watched a little further before commenting
@@BiIboSwagginsdon't forget that's because that was a sled pull and it was still in gear. In a normal manual that runs away, you can usually stall it in gear, those sled pullers have power sent straight from Hell lmao
8:29 Love that turbo flutter!!!!
First of all, that was a HECK of a tiller! Second: That tiller just wanted to do SOME WORK! He could have got the whole garden done with that runaway! But he would have been flapping in the wind behind it,
I thought my old 4 cycle 8HP was a big boy
One way to stop a runaway engine, is to put it in highest gear, hold the brake and release the clutch (if it has manual transmission). That might not exactly be good for the engine, but neither is the runaway.
I think a couple of them did that - You can see a lurch then it stops suddenly.
Won’t that make the transmission explode
@@tim8801 The transmission won't explode, but rather the transmission gears brake if it's build very weakly compared to the power to the engine. But if the transmission is build strong enough for aggressive driving with the current engine, it should also be able to hold up for a sudden clutch release in the highest gear.
Amazing how high the tiller revved.
amazing that it held together considering it was knocking badly even at low revs.
It was also perfectly balanced.
7:20 crazy it went from barely running to turning at like a motorcycle RPM
I actually had a petrol 2 stroke bike run away a couple months ago, very scary :D It's a Aprilia RS50, I was driving around 85kph in 6th gear and somehow it went out of gear and started revving as high as it can. I stopped and turned off the ignition immediately but it kept revving, I'm assuming because it got too hot because it was running leaner than it should and the A/F mixture started to combust by itself because of the high compression and heat. I then closed the valve on the tank to stall it out, put in a high gear while risking my clutch and let off the clutch, fortunately it stalled.
After I sat back and smoked a stress-cigarette, I tried to start it again and fortunately nothing broke and it was running fine afterwards but holy fuck did I piss my pants hahaha
I can confirm from a plate check EX04 XOA blue Ford focus is no longer with us.
Never turned up for it's annual test in 2020, I wonder why.

Co2 extinguisher right into the intake
Please keep in mind that a lot of the staged "runaways" on u-tube are nothing more than a throttle wired full open. All this gives you is full governed engine speed and does not have the same level of danger encountered with a true runaway. A true runaway begins to draw on an unregulated fuel source and will hit speeds(RPM) that are truly catastrophic. A staged runaway runs at full governor until the u-tuber gets bored and shuts it off because it wasn't as entertaining as he had hoped. Don't believe every clown with a "Runaway Diesel" video.
2:07 its scary how powerful engines really are if they are pushed to their limit
12:00 gramps knows what's up, and he ain't given up on that ol' 200yo cast-iron king
I love my ignition engine just that much more after watching this.
You can hold something on the air intake. An engine can only run with fuel and air. In case of a runaway Diesel engine, in most cases the engine burns engine oil, often from the turbo charger. Then you can‘t stop the „fuel“, but you can stop the air, by closing the air intake.
I think the funniest thing about diesel engine runaways is theyre avoidable if you spend a little money on an air shutoff.
The narrator speaking at the beginning” YOU CANT PREVENT A RUNNAWAY ON DIESEL TRUCKS. the only way is to keep your engine seals changed on a regular basis but even then if you get oil into the turbo it will just keep going with runaway. And the only way to stop it is to cover the AIR INTAKE. this will stop the engine. Use a bit of flat wood or a old jacket or jumper. Anything to stop air getting into the engine.
Fortunately, I have a gas car...
Agreed. Diesels are a pain in the ass.
7:30 And the RPM just keeps rising!! When will it stop?!?!
It can go 'til it blow 😉
Why hasn’t anyone putting a slide plate in the air intake. Control it from the cab. No air no run.
The fact no one tried to block the air going into the intake baffles me!!! The throttle isn't the issue people, you need to stop 1 of the major components of a combustion to occur. Air is your best option, unless you cut your fuel line and that wont help if shes too far gone 😂🤷♂️🤘
9:25 It's no use, that guy is deaf due to that screaming Duramax.
Wow, a 7,000RPM Duramax at 0:04 BEFORE it runaway?!?! NICE!!!! Hopefully one day Duramax engines can 7,000RPM with no problems!!!! And I LOVE CHEVY, better than Ford and Dodge COMBINED!!!!
For memory there is a company in the USA that makes a emergency shut down kit that fits to the intake manifold between the turbo and th engine inlet manifold.
interesting to see it happen to two MK4 golf's:
Their engines(usually the 1.9TDI PD) has a special valve that closes upon turning off the ignition. It's called the Anti-shudder valve(ASV) and is meant to stop the engine from sucking in air when the car is shut off to prevent that lumpy shaky stall most diesels have(as when you turn them off, they basically turn into a giant air compressor)
when the engine runs away, all that's needed is to turn the ignition off; the ASV will close and stop any air from getting to the engine. Or, if that fails, you can pull the arm manually from under the bonnet(it's a small arm attached to a vacuum solenoid, left of the EGR valve) and the engine will be 100% starved of air.
i must add(and this is probably why they ran away) that EGR deletes are very popular on the 1.9TDI platform. Unfortunately, the ASV valve is part of the EGR. when it's removed you lose this last resort valve in case of a runaway.
All engines are giant air compressors any time they're turning - it's just that they have some fuel (and or ignition) added into the mix to make it self sustaining
Im just going to add a valve when I upgrade the turbo. The engine is not complete without the delete. Noticeable power increase and went from 35-40 mpg to 60-90 mpg.
06:20 sounded like he put it in fourth gear and dUmped the clutch. Automatic transmission be damned
Some hilarious examples of "I've tried nothing and I'm all out of ideas!"
07:53 "Oh Scheiße" indeed matey.
Covering the air intake is the only way to stop it and that can be both a bitch to do and kinda scary
Using a block of wood is one way
Or have a fuel shutoff.
it amazes me how few people know how to stop this. i was a heavy equipment operator for 23years. i saw it happen several times. if you have a fire extinguisher, blow it right into the air intake. it will smother the combustion inside the engine.
4:08 why does dude have a picture of George Floyd taped to his window?
I saw that to lol
He admire criminals.
cause his car cant breathe
Disgusting.
@@xtYLT2IY8 it looks like it's breathing too much to me
These situations, scare me, but I hold calm, and control it.
(I wish it was that easy...)
I love the guy that just walks away…that’s precious !
6:32 That is gonna be interesting, since these engines are OLD!! Let's see if it will sound like a harbor freight engine (Like a Predator 212cc for example.) or a bit like a 4 stroke dirt bike!!!!
That dude who gives up and lets the hood slam at ~3:00 is too funny
The black truck puller hooked to the sled is my favorite. It shakes itself to pieces.!
I never knew the Ford focus had a diesel engine
Can you just run the clips without the tips at the bottom? A lot are misleading or just incorrect or just not what you should do at all.
6:32 how did that stay in one piece? 😮
oh man 2:47 that guy has the look of disgust. he just knew it was done lol. slammed his hood down and just walked away.
I knew a guy that had his combine runaway on him
It started a fire because of the fodder against the overheating engine.
GOD DAMN That first one went so hard I thought it was the brakes for a moment glowing red hot.
Feel bad for that elder man at 11:12. And for that historic engine.
BRO STOP
2:53 The moment you know your car is done for. Poor guy. :(
Bro is here to shit some light 💀
If I had a manual transmission, I think I would put it in a higher gear and pop the clutch while holding the brake down to try and stall it.
Could just hang on and enjoy the ride ? 😂
The amount of people who don’t have a kill switch is wild! 700hp Duramax and my 950hp race 5.9 Cummins both had opposite flow kill switches.
Never know there were so many small cars with diesel engines.
the black one hooked to the tow tester was angry af
If you have a diesel car with a **manual transmission** that goes engine runaway: stop the car (if moving), handbrake on, shift into the highest gear (5th or 6th gear), and stall it.
The guy in clip 9 tried that first, and burned out his clutch.
IS THIS VISORACER?! YES!
7:00 that tractor that sounded like a motorcycle before the guy said "Oh schiezer" was funny.
Not even after the intro: So much torque, the chassis started twisting immediately
8:27
Exhaust: explodes
Runaway: stops
Me: how?
Geez that first one is the most violent runaway I've seen
What the?!?! Was not expecting it to go past 8,000RPM at 7:27!!!! It sounds just like a dirt bike!!!!
why the hell did that blue ford have a pic of george floyd on the window
Good thing those black trucks at 2:00 and 2:15 never unhooked , Could of ended very badly wow !
yeah, it's good that this beast remained on the chain
@@CheckEngine69 Roger that !
10:32 Stopping the runaway the NERDIE WAY!!! YESSIR!!!!
7:06 - Imma go 2-stroke, man!
Vast majority of people don’t need to worry about run away engines as it is very very uncommon.
Ive seen so many people saying if your diesel runs away, youre gonna have to hope you dont crash. Cant you just slow the truck down by putting it in neutral?
You can stop a runaway by covering any air intake
#12 sounded like it was already knocking, I'm not surprised
bros truck turned into a steam locomotive 0:03
put in top gear,dump clutch while holding the brakes will stop motor
I like how In #9 the announcer is giving instructions on how to fix it
9:52 What a nice sound!!!!
You missed a way of stopping a runaway diesel. Simply shift into the highest gear and dump the clutch. This will stall the motor ending the runaway.
*New fear unlocked for my Passat* 🥲
#12: NASTY rod knock or whatever that is. Then it goes off the rails, but it "self-corrects" quickly. When it finally dies, the operator: "Scheiße..." 😛😛😛
"You can't park there, mate" 😂
If this is a thing why don’t auto manufacturers put something like an emergency shutoff switch that engages a plate to slam shut over the intake?
7:53 ”ahh sheize”😂
Tip (i think): the vehicle comes to a halt and then the engine starts going crazy
Why noone stick something into air intake, to stall the engine?
We just had our excavator run away and my buddy isnt afraid of much but that day was the first time i seen him afraid of something 😂
Maybe a bad idea this is not anything I really know about but why not keep a decent sized co2 extinguisher around just for this to spray into the intake?
3:31
what you see in the text of the video is wrong. a diesel runaway is basically when the engine starts running on its own engine oil. This is caused by worn piston rings or other causes. Since the compression of your diesel engine is high, the temperature of the air compressed from your cylinder rises and becomes hot until the engine oil reaches a flash point and ignites. option to stop this find something to prevent sucking air into the engine
Where did you get the thumbnail from? You know, where the bulldozer is shooting fire out of its exhaust in a cold mountain area?
That is actually a stack fire. It can be caused by an engine running away, but it can also be caused by an overheating engine. If it's the latter then once the engine cools down the stack fire goes out.
So u can't put a contingency mechanism in place at the intake or exhaust?
That is how good the Chevrolet Silverado Duramax runaway was, to have 4 PARTS!!!!
did you really feel the need to comment 12 times when you could’ve kept it in one message
@@ZGold-v9s I was just about to say that
If your engine has an important oil leak, you know it as soon as you control the levels frecuently... and leaving a failure so bad, leads to dramatic scenarios like that...
8:15
The text does not make any sense, why would it be harder to access the ignition switch if the engine is running at high RPM?
Furthermore, if a runaway occurs (particularly in a diesel engine with a mechanical fuel pump), it doesn't help to turn the ignition off since the engine may run from other "fuel" sources (such as engine oil or coolant)
You can even disconnect the battery terminals and the engine would still run in the event of a runaway.
Dump the clutch , if that doesn't work choke the intake
Tapar la entrada de aire del colector del motor con un trapo o una camiseta, o meter la marcha mas larga del motor y soltar el embrague (en vehículos con cambio automático solo se puede tapar la entrada de aire.
Asi se para.
This is why I always have something to block the intake of my tractor if it trys to run away.
