Funny old thing Like something off Thomas and friends!
“Old Smokey”
Rikki-UK:
Speak to any Lister Petter engine owners- they were/are well known for sucking up the sump oil and blowing themselves to bits- no diesel required once its started to runawayAnd the reason you use a higher gear to stall simple by stalling that way you are putting less torque through the clutch minimising the risk of destroying it,
Rikki its the same ones that would try to stall a run away truck engine in 1st that would try to bump start a car with a flat battery in 1st and wonder why it locks up the wheels and doesn’t start

How the hell you putting less “torque” through the clutch?
Same engine,same flywheel,same clutch ,same gearbox.The “torque” is supplied by the engine.
If the input shaft is locked does it make any difference which gear is selected.
And when was the last time you saw a Lister engine with a blower?
The Lister used unit pumps and oil got into the pump gallery .This was then “injected” into the engine and didnt “magicaly” appear in the cylinders from the sump.

Some tripe on here.
40 years in the job seen turbos split,sieze,explode even but one where the “cold” side seal blows,pumps oil into the engine after filling a 20 litre intercooler with oil.then the engine burns a low aromatic fluid like oil in the chambers without first locking by trying to compress a fluid is one I cant wait to see.
And dont give me that bollox about oil “mist” in the charge air.If you remove the diesel that engine stops.
Dont you just love “Urban myths”Its an urban myth that a diesel engine only runs on diesel! I have seen big diesel engines run to destruction after a turbo failure, the turbo has exploded first and is then followed by a hole in the side of the block where it chucks out conrods for fun.
And what happens when the turbo fails?Instant oil pressure loss as the pump is effectively pumping to void where the turbo used to be.Any liquid under pressure,as with electrical current,will find its path of least resistance.
All pressure is lost to the mains and big ends.Thats why the con rod fails nothing to do with overspeed or running on engine oil.Try filling your fuel tank with 10/40 engine oil and see if the bugger will run.

Hi Luke <fx: waves>.
Are you talking about a failed turbo or a hole in the engine where a turbo used to be?
Do you know how a turbo works & what job it does?
Does every turbo failure result in a runaway engine?
Is every runaway engine the result of a turbo failure?
Are runaway engines a figment of the imagination of all those who experience one?
Perhaps ‘Bertie’ has taken over the throttle?
I think that should keep you quiet for a while, whilst you look up t’ answers on’t t’internet.
Carry on old chap. Splendid indeed (cough cough). Don’t forget to adjust the cravat before you jump back into Switchlogic’s persona.
Quite right Bkng the Detroit is a 2 stroke the flap is mounted in the air intake ( sorry about calling it manifold ) and has been as i stated before since the 40,s and it is there precisely for the purpose of stopping the engine should it start running on. ( Worked, rebuilt, driven in plant, trucks and boats for 35yrs. Inline 3/4/6,s V6/8/ 12/ 16 /24,s maybe i should go back and reread the manuals? )

Good old Burgerking with his I’m right and the rest of you are wrong Bollox . Yawn

Educations a wonderful thing!
you should try it some time.

I have that 2 years at college studying mechanics, we had a car there that the turbo seal went on and the engine ran on its own accord, I think we used a CO2 extinguisher to stop it, can’t remember what car it was tho
Ok, I too had years " on the job " and have witnessed a Volvo F7 set off on its own due to it having the turbo replaced after major failure and the intercooler didn’t have the large amount of oil cleaned out of it . I understand where you are coming from with it Locking up once the oil was sucked in but this wasn’t the case it just set off at full chat outside the workshop. My mate pulled the engine stop and nothing happened by then there was clouds of smoke and a smell of burnt oil so he just ran it into a pile of old tyres stacked against the workshop wall and stalled it, I don’t know what gear he used though lol.
While attending college as a lad they had a few truck engines sat in frames that we used to mess with and one day the Foden 2 stroke engine they had set off at full revs, although it wasn’t running on its oil it was still a sight watching the teacher feed rags into the inlet to stop it and chopping the fuel lines whilst they evacuated the nearby classrooms lol. The sound was deafening
Well what can I say.Clearly all these diesel engine manufacturers are wasting their time pressurising fuel up to 2000 bar,producing multi hole injectors to get full atomisation of fuel and producing variable geometry turbos to give accurate air induction levels when all you really need to do is let a bit of old crappy engine oil seep into the combustion chambers via the induction manifold to produce enough power to overcome the brakes and still have power to wreck the engine left over.
What the hell do they need ecu controlled multi stage injection timing for when you can just pour a bit of old castrol into the air filter box and a compression ratio of 16 to 1 will get it to burn with the same power output of a nuclear reactor.
Maybe engine oil is the fuel of the future eh.
Full o ■■■■■ or prove me wrong
Full of “profesional” ■■■■■■■■■ who know bugger alll.
So the examples of this actually happening in the videos above don’t actually exist, they’re just a figment of our imagination?

Explain why the input shaft is locked then? Because the handbrake is on? That would be the output shaft
And in a 16 speed for example you have 16 ways of trying to make stalling less stressful on the clutch, number 16 being the one to go for.
Actually if you wanted to be really ■■■■ about it, it’s the brakes that are held solid. Everything else will have a dgree of movement. So in first gear you will wind up the gearbox, driveshaft, diff and half shaft before cutting out. But I agree it will cut out. However in top gear the wind up is less because higher gears reduce power to ground.
It’s why you change down gears going uphill.
Correct. The strain on the driveline would be terrific in 1st gear with a say 440 horse engine revving at what, 5 - 10,000 rpm?

Have a look at the smoke that a runaway produces. Hardly acceptable for a modern engine is it? Maybe that might be why injection pressures are so high on modern engines■■?..
Shoving engine oil into the intake of a CI engine is not exactly going to give a controlled result with regards to engine RPM or output is it?
It also burns uncontrollably causing severe damage to piston crowns from detonation, not to mention the damage done to the bottom end from lack of lubrication due to engine overspeed (even if the oil pressure is ok the oil will centrifuge in the crankshaft at very high speed)
“Maybe engine oil is the fuel of the future” Why not? Large industrial diesels run on crude, and have done for many years!! Can’t see them changing any time soon

The trouble is in Burgerking land nobody else dare have an opinion , the YouTube videos don’t exist , others myself included who have witnessed this are all liars
You should know what to expect from a " I’m better than you FITTER " who quotes crap from a manual to try to waffle us
Here’s an idea, why don’t you try and prove the rest of us liars who talk tripe and Bollox wrong as you mentioned earlier education is a wonderful thing. Self opinionated knackers is something else.
Most fitters are all the same.A big chip on there shoulder.
The one talking tripe is the chap whats posted such a laim brain reply.of talking tripe
you sure you been in the game as man and boy. Were have you been in 40yrs not to see this happen■■?
