Diesel engine runaway is a rare condition affecting diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM and producing up to 10 times the engine's rated output until destroyed by mechanical failure or bearing seizure through lack of lubrication.

As a diesel mechanic we were always told co2 fire extinguisher pointed at intake is the best bet for a fast stop
Someone said that "if you are brave you can stuff a T-shirt in to the intake"
Hi can u tell me why my my 2.2 xtrail has gone into limp and idles around 1 and half but want rev more than 3 rpm
@@craigsorensen7425 theres perhaps to things going on
1 the computer neads resesting
Turn engine of wait 2 minute and restart .dont touch the accelerator just let it idle a bit then push down slowly .snd all
Should be fine .No 2 if its a diesel it could be a fuel line air
Leek when engine is warm and its switched off the fuel cools coursing a vacuum in the systam its no good looking for a diesel leak air is thinner than
Diesel so it only works one way
Our to test find a high pressure
Fuel pump from an old petrol car pull the pipe from the tank
To the filter just touch the wires
Onto the battery it will quickly build pressure dont leave it on
For more than a couple of seconds look around the the system and it will be obvious
Where the air is sucking in
Fix the leak . Remove the pump
Keep this by for future use .bleed the system and of you go .if it happens again
Craig fvcknose what it could be
U just got to us your loaf and
Get some innovation on the go
Good luck let me know if it works for you
A block of wood on the intake or turbo normally does the trick
@@Nikkerston yes will work pobs oly way to stop it
Also, NEVER try to to choke a runaway's intake with your bare hand! Unless you're a pirate who is unhappy with their remaining good hand.
Gahhh, you know someone must have done that at some point though 🤢
Arrr, matey. That was the best pirate joke I've ever heard.
Had a couple of locomotive engines runaway when I was on the railways. It’s pretty scary when you carnt Stop a 200 litre engine. One of them threw a rod out the side of the block once. We found it in the middle of a farmer’s field.
cool
Sounds scary
"I see a con rod", Don't you mean Concorde?" No, duck!😁
Geez, how many feet did it go?
When the engine's so big that the term 'throwing a rod' is meant literally.
Happened to a buddy and I in his VW Rabbit diesel. Had just helped him do an oil change. Apparently one of us miscounted the quarts or something. We drove like 15 miles, but then went up a 17% incline highway and suddenly the gutless wonder had us doing 65mph and climbing faster and faster. He started downshifting then started upshifting but only went faster of course. I finally said "pull over and put it in neutral... and shut off the key... she's done for." He pushed in the clutch, but the oil had to have burned off and we were on a flat at that point and it went back to idle. Was the fastest a VW Rabbit diesel had ever gone, let alone up a 17% incline.
Stupid, you should put it in 4th of 5th and stall it…

@Winahh Taylahh One should research before making accusations out of the blue. We DO use metric. What that has to do with miscounting bottles of oil is irrational and shows you have an obvious axe to grind.... but here's some insight as to why the US isn't officially metric in the YT video link below. Short and sweet spoiler: Metric started in 1790 in France and wasn't an accepted standard elsewhere at that point... when the industrial revolution hit, everything was tooled for Imperial (1825 standard we know today). To suddenly change all the tooling of the largest manufacturing machine the world had ever known at that point was close to impossible. It IS slowly being changed... so calm down. There are other problems in the world to give a crap about.

overfilling crankcase oil on a diesel engine won't cause the runaway effect, but it will blow various engine seals.
I remember this happening during my time working as a mechanic. I had just served my apprenticeship and did an engine swap as one of my first big assignments and this happened to me. Did some research and found out that a bit of oil was in the intercooler causing the engine to rew like I had ever heard a diesel engine rew before. Luckily I managed to choke the engine before it went too crazy, but damn. I will never forget the few seconds where I just stood there panicking. They felt like an eternity.
Glad you had the intuition it instead of panicking and running away like most people would.
Thats why you always get the intercooler cleaned out when you put a good engine in to replace a stuffed one aye!!
Looks like a 🚜 pull!!😊
Had this happen on my mk6 tddi transit van. Suddenly the van accelerated away with a huge white cloud behind it.
Pulled over, handbrake on foot hard on the brake, put it in 5th gear and banged the clutch up hard. Stalled it out and saved the engine. Turned out the nose seal on the vp30 diesel pump had failed and pumped 10 litres of diesel into the crankcase. The level rose till it was sucked through the pcv valve through the turbo and intercooler and blown into the intake manifold. Engine was feeding itself. Changed the diesel pump, drained and flushed the sump.
New oil and six years later the Van's still going strong on the replacement pump. If you stall it out quick enough you can save it.
Very unnerving when it happens the first time thou. Lol.
That's fucking amazing that you were completely able to save it. Good shit
Yaaargh! That's the noise I'd have made anyway 😂
Its actually really impressive how long they can go for.
As long as there is oil in the engine, unless someone starve it of oxygen or stall it
Runs out it's 2million miles in 15mins. Great save with the rag to turbo!
@@XavierAncarno Or it jam by owereheating it happend a lot sooner then eating all oil.
I was thinking the exact same thing especially with the first car that was shown
If the components of the engine can handle abuse, they will most likely last afew minutes.
if you are quick you can block the air intake.although easier said than done, best maintain the engine correctly with regular checks
You beat me to it... was thinking the same thing. They should have a valve on the air intake that you can close... ah, just got to 6:12...
@@user-pw6qe7ur4q yes there’s a flapper, I had to shut a big Detroit 12V149 down on a gen set after she took off, you should have seen the other guys trying to run through each other 😂
Rule of thumb when rebuilding or cold starting an old diesel after a long period of time. Always have a board and rags, or a CO2 extinguisher right next to you. New turbos tend to drop seals, and the old diesels (especially abandoned ones) tend to have the injection pumps stick wide open. If you have board and rags, or extinguisher right next to you chances are you can stop the runaway before any damage is done. This of course is assuming you get on it right away as soon as it starts to run away.
or just cut intercooler pipe to the intake manifold and pcv valve with a knife my opinion 🤔
Unless you can push the cooler pipe to the side your in trouble I have seen a series 60 Detroit blow a cooler hose while running away and it just shot the oil straight through the gap and keep going
This happened to me in a Ford Focus Diesel, fortunately it was a manual gearbox so I stalled it. Turning the key off did nothing. Used its own oil as fuel. Totalled the engine. Turbo seal failed.
Same happened to me in a TD Escort years ago.
No big loss!😂😂😂
Smart man right there on the third vid….Choke the air supply completely!! 😱👍🏼
I worked in the shipping/ferry industry and have witnessed this event on numerous occasions, quite scary to say the least.
Wait on boat?So it was super quick?
On a boat!? I'd imagine that would turn your average ferryboat into a speedboat for a few minutes
This usually occur while shore side and the engines were under test with limited applied load.
You'll notice you do not see VW TDI's running away as often. Older TDI's have "shudder valves" that is a flap in the intake that closes when the ignition is switched off, newer common rail TDI's have throttle valve before the EGR flap. Both block intake air when the key is switched off.
Yep, all the Pumpé Duse engines have the shudder valve under the EGR valve.
Thank you lol this vid was about to discourage me from getting a newer VW TDI
Lot of VW have butterfly to stop it , can you block exhaust maybe slow it down a bit . Most cars have rubber hoses give them good squeeze get sucked in and stop
shutter. Ts, not Ds. ShuTTer.
Old Detroit 2-strokes had them too because those things are so prone to fucking off like this.
Just experienced my VW Passat 1.9 TDI doing a runaway. Heard the turbo go off, had to try get to a place I could stop but before that the RPMs started going crazy. Tried turning off the engine while I was still driving. even took the key out, and it did nothing. Had to kill it by shoving the car in 1st gear and holding the brakes. No fire thankfully. Engine is probably trash though.
Not only a knackered turbo, but overfilling the sump with oil can also cause this on any diesel engine when it's hot.
Run it through the gears and have fun!
This is why newer diesels have anti shudder valves
There's no anti-shudder valves. It's a SHUTTER valve. Ts. shuTTer.
It's also not new tech. They were on Detroit 2-strokes before any of us were ever born. just a cable operated door on the intake tract to choke it out.
Or just buy a normal gas truck like the rest of us
@@TestECull Yo, thread cop - get a life.
@@TestECull On some vehicles they're called anti-shudder valves. Primarily, they prevent the shudder during engine shutdown but they also provide runaway protection. Had to replace the anti-shudder valve in my X5. In the X5, it's also used during DPF regeneration to trim the incoming air and prevent an increase in RPM as extra diesel is injected during regeneration. Quite a valve.
@@jr798 There's got to be a way to run the regen map for a hit of boost
Had a detroit 8v92 runaway at work one time. The "choke board" had somehow come up missing so the guy that pulled the truck in to work on it grabbed a fire extinguisher. Yep, it worked. Yep, needed a new engine after that.
Should’ve gotten a CO2 fire extinguisher. It would deprive of air. That’s why dsls w no turbo are nice, it’s harder for em to run away.
choke board? You know 2-stroke DD's have a emergency flapper on the blower right?
@@73Datsun180B the old dd flapper on the blower, yep! Right next to the skyhook larpation hanger widget.
When I worked at a construction company, one of the items in our mechanic toolbox was a ping pong paddle. Ping pong indeed was his hobby but also the rubber side of the paddle had the perfect shape and size to put on a air intake like a lid and choke a runaway engine.
"it's runaway grab the ping pong paddle!"
"The ping what?"
"The ping pong--"
*Engine has left the chat*
Another way to stop a run away engine, if you have a manual, in a vehicle with air brakes, is to dump the clutch, in a higher gear, such as 7th gear, with the brakes set. It does risk damaging the drive line, but will stop the engine fast
"That engine's wanked"
That's the Irish technical term 😂
The little Toyota put up a hell of a fight though. Legend has it the smoke is still dissipating
Freelander no?
I like the dozen or so explanations lol
That's a Land Rover
@@MattExzy his commentary won the internet
So it is a Land Rover... Makes sense really.
As we say in Australia; If you want to go to the outback, take a Land Rover. If you want to come back, take a Landcruiser.
I know that's not an actual proper off road Land Rover, but the sentiment applies for the scenario and my unfair misidentification.
Saw this happen twice when I worked for mercedes, both 3.5l V6 deisel ML both happened in the workshop, never seen mechanics run so fast!
Worn piston valves is usually the cause. Had a Worthington 75KVA diesel running a generator that ran away. Normal RPM was 360, the tack went to 500 it was pegged. We chopped holes in the intake intercooler with fire axes and dumped three 500 pound Co2 bottles into the intake.
For my Holden Rodeo it was a rubber oil seal in the turbo let go. Not a fun experience.
Scariest thing I've ever done was stick my head under the bonnet to pull the fuel line. Had visions of a piston taking my head off as heads skywards at a large rate of knots.
Piston valve? 😂
If you are already under the hood when a runaway first starts, blocking the intake or co2 extinguisher can stop it, but once it takes off on you, getting it into high gear is not likely, get away and keep people away! Let it run its course. If anything disloges from outside or inside the engine, it can be deadly! This is not just a great video opportunity, it can kill people.
I know a mobile diesel mechanic who is really, really good. I was working on a Ford F350 with the 7.2 (I think). My boss had called him out to help figure out what was causing a random loss of power/stall. After doing a few mins of diag, he found the fuel was cloudy. He said it was because the lining in the tank had failed. While he was there, he was also telling me that the turbo had a lot of oil puddled up around the inlet and could cause a runaway. We talked about that fow a few mins and then he told me something that chilled me to be bone. It was very rare but had happened to him twice: Sometimes, the wrist pins can fail. If it happens while the engine is running away, the crank can launch a piston straight through the head. Said it happened on a 5.9 Cummins and after going through the head, proceeded to tear right through the hood, hook a hard left and take out the A-pillar and windshield of a car sitting next to it.
This is why I don't work on diesels.
Never let it run its course if its yours and you love her. th-cam.com/video/1g0s2PMUdrI/w-d-xo.html
ok Prudence, now go back to bleating at people about safety glasses...
@@TestECull safety glasses aren't a factor that connecting rods or piston shrapnel coming at you at terminal velocity consider. I lost a friend to a situation like that. There's a difference between bleating and putting relevant information out there for intelligent people to consider.
@@TestECull It’s all fun and games being so advanced that safety isn’t an issue. Being blind, is just as cool. You get to wear sunglasses all the time. How awesome is that?
That Ford diesel engine didn't last nearly as long as the others. Makes sense.
Yeah typical Ford:)
I watched this video a couple of weeks back, I'm from South Africa. I have a Tata Superace diesel van, for a few months I've been having a diesel knock but no finances to get it seen to. Unfortunately today I experienced this Runaway diesel engine today, however I found the easiest way I was able to save my engine was by putting the vehicle into second gear as the vehicle was parked then I came off the clutch and stalled the vehicle. The engine stopped running and I saved my engine, just thought I'd share this. My runaway diesel engine was caused by faulty injectors.
R.i.p to those diesel engines that blown up
Good to see that there are informative captions, and that it's not the usual TH-cam destruction fest.
Put it in 5 gear hold the brakes and dump the clutch pedal. Very easy to stall the engine.
Unless it’s an automatic trans…
Need to block the intake with something sturdy so it can’t get air. Sometimes something like a Co2 extinguisher can work if it’s big enough.
you can see in 3rd video, the engine hits the high rpm almost instantly, good luck stopping 300HP with a clutch
no way , if you have a decent engine you would smoke your clutch instant
Unless it is an automatic.
@@DreStyle if you have a high performance engine you have a high performance clutch to handle the power
happened at my old 2 cyl.tractor. a cloth strongly pulled at the exhaust pipe and a bit of luck, but it was impressive!
Ogień na tłoki 🔥
Ashamed how many people who drives diesel vehicles that often has a fire extinguisher on board is the same tool that can save your engine
"The engine's wanked!" LMFAO!!!
Dump the clutch in 5th, managed to save my engine by doing this when the turbo went and started sucking oil out of the sump
You and I seem to be the only one’s that would have the common sense to do that, top gear with a hard brake would stop the Earth rotating!
@@Luton-MickI was on my way home and had just come off a roundabout and it started accelerating like the clappers and I thought straight away there was something not quite right so immediately did it and killed the engine, saved me an engine swap, still cost £600 for a new turbo though 😯😯
In the case of car or truck that is diesel and has is a automatic the only way you can kill it is to block off the intake
Or unplug the ecm or pcm
@@dan379 the only thing is really electrical on a diesel engine is the fuel shut off solenoid but most of the time when diesel runs away it's because it start burning it's own oil so therefore the only way to shut it down is choke off it's intake
The term "runaway" in this video seems to mostly reflect the actions of the drivers. Quick, run away... it's going to blow!
you can also smother a runaway with a rugged jacket covering the turbo or pulling the ducting to the intake and covering the hole with the rugged jacket..board even if you can😀
In the marine industry in the past I have learned that the only way to stop this is to block off the intake air. A block of wood is the best.
NEVER put your hand in front of a runaway diesel. Diesels will not stop to think what it's sucking in. If it's far enough gone, it will suck a hole through a wooden plank if placed in front of the intake. The guy with the classic truck is lucky to have all his fingers.
Under these circumstances the only speed limiter is when the engine floats the valves (it goes so fast the valves can't fully close, so any increase in speed causes loss of compression and thus power and any decrease in speed causes gain of compression and thus power). Robbing the engine of air is really the only way to stop a runaway diesel.
Stick it in 5th and dump the clutch
@@stokesy887 your transmission will become tetanus soup.
I have a pond drain valve between my filter and turbo so I can block air getting through.
Quite scary to watch, but also really interesting!
Not at all but fun to watch!
Great vid! Leaving the commentary up long enough to read is a first, thank you...
I've used a CO2 Extinguisher to stop a Cat Grader Engine Runaway. Sprayed into the Air Intake. The Turbo was leaking oil into the intake. The CO2 shut it right down.
I had this in a sprinter truck after overfilling with oil. Unfortunately it was five o’clock on a Friday evening trying to get out of London. It eventually stopped after driving for two hours in second gear.
That was somewhat satisfying
These runaway’s amuse me when a top gear clutch dump and a hard push on the brake will stop it dead.
It will if it ain't an auto or the clutch is near screwed...
That's when a hunk of wood or something that you can block the intake with helps :)
@@DigBipper188 fire a co2 fire extinguisher into the air intake works a treat too
@@reddyreddy2618 Aye if you have one :)
What happens if this happens whilst your driving on the highway?
@@bigmatt1994 You have a perfect excuse for doing 140 in a 70 and failing to stop for the cops, of course!!
A tandem pump (pumps diesel and oil in two chambers on one electric pump) on Audis and VWs in the 1990s through to 2015 always go (sometimes within a year of ownership) resulting in diesel mixed in the oil which leads to runaway.
Dad had this happen to Mum's VW Touran GTD in 2010. It detonated the engine despite shutting down on key shutdown due to the electric pump isolating and no longer pumping. Diesel engines with mechanical pumps can only be shut off by preventing oxygen from entering the engine.
All high-end turbo diesel vehicles should have a CO2 extinguisher.
I'd probably plumb one in now I think about it, have a solenoid energised by a 'aircraft gun' type trigger protector somewhere in the foot well.

LMAO! 😂 Greta can suck it!
6:00 poor guy, new exactly what happened and had to grenade his turbo before the engine did. The greatest sacrifices require the strongest wills.
3 things a gas engine needs to run- air, fuel, and SPARK. A diesel does not require spark, instead the compression ratio is much higher, which atomizes the mixture and due to the high pressure creates any fuel to ignite. No spark plug needed. Soo, if a rogue fuel source such as a blown turbo seal that leaks directly to intake, due to its nature will run without the ignition. The only way to stop it is to cut off its air supply via turbo or carb. The ignition switch only controls the electronic injectors. And diesels will burn almost anything for fuel. If left running it wont stop until the leaking turbo has drained all the crankcase oil, thus the white smoke and engines ending up siezing and blowing all coolant out. TOAST!
Can’t you just drop the clutch in top gear with your other foot firmly on the brake?
@@Luton-Mick you can but it will most likley cause more harm than good, you will probably need a new clutch at least along with the motor
Compression ratio doesn’t atomise fuel at all
spannaspinna Simply super heats it to its flash point! Atomises....as you say, no! Cheers
@@spannaspinna Yes in fact it essentially squeezes the fuel atoms closer together causing the auto ignition
Happened to me years ago with a old series 2 land rover fitted with a early defender 2 5 turbo, pre tdi, seemed to go on forever
Very interesting
I had this happen with my Nissan X-Trail. Tried to stall it with 5th gear but it shredded the clutch and eventually ran out of engine oil, needless to say it was fubar. 🙄😳😡
I'm guessing your stall attempt didn't work, and it just ran until its valves floated.
@@jwalster9412 pretty much. Nice cloud cover. 🙄
I've had a runaway where the fuel rack in the fuel pump jammed. The engine was on an old harvester that had sat for a few years, and at some stage in the past someone pressed the cold start/excess fuel button putting the fuel rack at max, then over time it seized there. So when I decided to give the old engine a run, it instantly runaway...instinctively I pulled the stopper but the rack was so seized that the cable on the stopper couldn't move it and the outer of the cable which wasn't clamped very hard just slipped instead. I decided to risk it and climb up the back ladder with a screwdriver and lever the stopper across....it worked but not before a cross shaft got so out of balance at that speed that it bent itself up throwing off the belt driving it.
Love that sound though. Imagine flying down the highway with it sounding like that.
That's actually the sound of the engine over revving, probably over tourqing, and valve valve float. These *Will* cause a rod to be thrown through the side of the block.
Happened to me today going 100kmph down the freeway, it was actually terrifying hahaha.
I swear, old Freelander's are nothing but trouble.
Only reason I came to comments was to see how many ignorant people would say "cut the fuel line" or "disconnect battery". If you don't know what you are talking about don't talk about it. Lol!!!!!
Maybe they should just disconnect the spark plugs, or pull the distributor. Perhaps the points were messed up, and the carburetor float wasn't set correctly. Diesels have some of those, right? 🤨😁🤣😂😜

“Eco friendly” 😂
At 6 minutes in, improper adjustment of the governor buffer screw likely caused this runaway condition. Don't ask me how I learned that. :-) Good job shitting of the air supply at the turbo inlet.
Had a truck do this at a garage I worked at in the 1980's.
It had damaged piston rings (and dropped a piston subsequently) and other fire rings were worn, causing it to draw up oil into the
The 'experienced' mechanics jacked up the cab, undid the injectors...nothing.
It just kept hunting (high revs, low revs alternating).
Me, being an apprentice at the time, offered a possible solution, but was told to leave it the the "guys who know what they're doing".
After 15 minutes, and no success, they asked me what I thought.
I dropped the cab, jumped inside, kept the deadman on, put it into a high gear (fourth in this case) and dropped the clutch.
Yes, it jumped a few feet forward, but it killed it.
Edit: yeah....just got to 7:29.....and there it is 😖
The problem might be that nowadays an increasing number of cars do NOT have manual gears anymore, so that trick of putting in high gear might not work anymore.

@@SimonBauer7 I know because I live in the Netherlands and have a manual one myself BUT there's a clear trend towards automatic for very sensible reasons. In Germany you can legally speed on the Autobahn but in most countries it's choosing between snail speed and donkey speed when you're stuck in the traffic and the max speed has decreased to 100 km/h on the highway. So automatic is a good choice nowadays.

Yes, these are old diesel motors. Most of them not in the best condition. But the younger, mechanical good diesels are not so problematic.
The mostly responsible for solutions are the powerplants and the transport ships! Not the modern diesel cars!
Every run away diesel start to eat up its engine oil. Remove the airfilter and cover the air intake fast as you can. Alternativ: Put in the highest gear and and step on the brake as hard as you can. Do not start the engine again!!!

Captions are right, Diesel engines will run away on gas. The oil industry compressors and generators have an extra over speed protection. Many have to cool the exhaust gas so that it leaves at a temperature below the ignition temperature of the expected gas.
This has happened to me with a digger, I stopped it by starving it of air (Basically covered the intake with my t-shirt)
I see a lot of comments saying that engine oil is getting into the cylinder and ignites, but can a faulty solenoid shutdown valve cause a diesel to run away too?
Our instructor in Generator school in the US army said that a phone book would work in putting it at intake,but whatever it was ,it had to be thick enough not to get sucked in. I don't believe I ever saw a phone book in the field. With all due respect!!
A diesel engine should have an emerency decompression valve cable operated!
It would decompress the engine to stop this.
It could be on the cylinder head or on the intake to choke the engine down!
Fuel needs air to burn, you stop the air and you stop the engine. If you keep calm and think first instead of thinking all hope is lost, a runaway diesel is easy to stop
I had one small dsl I accidentally over filled w oil & it started to run away. Luckily I had rehearsed how to stop it, & shut it down. Removed the excess/abt 1/2 a qt of oil. That’s a lot for a small 6.4hp Yanmar dsl.
You wonna stop a dsl, throw it in 5th & dump the clutch. That’ll kill it. A new clutch is cheaper than a new motor.
Idiots that just let a dsl go w run away should never own one in the first place & should’ve gotten a crappy gasser.
@@michaelbenoit248 instead of risking the clutch or gearbox how about stop the air flow. You can stop a 4 cylinder diesel by covering your hand over the intake. I’ve even stopped a cat c15 with a piece of plywood over the intake. It’s easy

I believe that the easy way to stop a runaway diesel engine is to stop the air flow Tru the engine, same happen to a fire 🔥 .if the engine don't get air flow Tru the inside cannot keep running..

With the land rover if the air filter was blocked the engine would stall. Whose ever it was just left it.
Yeah, I see guys that just let the motor go. I’ve been around a screaming motor before, it’s scary, but to be clear. If something goes boom it’ll go downward. Most dsls have strong head bolts/studs they won’t fly off. If it’s not stopped you’ll trash your block.
I was screaming at the 1st 2 videos block the air filter! Thankfully the guy with the old truck knew what to do. I have very quick access to my air filter as soon as hood is opened and I keep a plastic bag in my truck should I ever need it. 10 cent insurance to save from a $10,000 repair.
An old mechanic told me if Ur driving a diesel keep a block of wood in the car just big enough to cover the intake manifold
This just happened to me today off roading in an old Landcruiser. It's scarry as hell.
this is very sad :(
Did you manage to stop it?
Miałem kiedyś taką sytuację w Sharanie. Wystarczyło wrzucić 5bieg i ruszać. Silnik się zadusił i zgasł.
Albo wcisnąć szmatę w dolot. A najlepiej potrzymać silnik na wolnych obrotach, zamiast od razu go gasić. Ja zawsze czekam pół minuty, zanim zgaszę silnik, żeby turbo w dupę nie dostało.
Chyba hamowac?
if cutting off the air supply by using a fire extinguisher and pulling the battery out of a runaway engine doesnt work. how would you stop the runaway engine?
run to a safe place behind a building and wait for pistons to rocket through the engine or for engine to explode
In this case you can try to put a high gear try to sufocate the engine closing the Air intake or disconecting the diesel lines
Disconnect the diesel line will do NOTHING the engine is running on its own oil... Starving the air by blocking the air intake with a cloth or a wood plate will DO SOMETHING
Had that happen to me. Some random guy just enter the car put a high gear and stall the engine. Don't know if it works in all situations/engines.
With a manual gearbox, you can do it but with an automatic gearbox, you should put cut oxygen entering in air pipes (having a little co2 fire extinguisher in car is a good idea)
Imagine being inside a car in a garage with it having a runaway engine
Pure CHAOS
You'd be getting out of there pretty quick otherwise you'd die 💀
Usual cause - failed oil seal in the turbo, oil used as fuel pumped straight in.
9:50 Last option rubbish! It's the obvious way to stop a runaway.
Interesting video tho. Thanks!
