Plus it washes oil off the bores, causing wear. Use with caution: ie as a one off to get an engine going, not because you can’t be arsed to fit new heaterplugs (diesel) spark plugs (petrol).It cracks the rings and what bloody truck engine has heater plugs they use flame start or manifold heating.
Is every bugger on here living in the 60s?
This thread stopped being exclusively about truck engines some time ago.I’m amazed you keep returning to it.
So am I! The weird thing is every body has “seen” it happen.
Been in the job 40 years and never ever seen a “runaway”
Heard about loads of em but never seen the evidence
Maybe Im just “lucky” eh
Lucky wasn’t the first word that popped into my head as a way to describe you

There’s ■■■■ loads of video’s on youtube of the phenomenon!
Ask my local MOT tester that it never really happened to my Mrs’s old nail Mondeo!
I don’t personally know anyone who’s died of cholera…but that doesn’t mean that it doesn’t happen and that we shouldn’t take basic precautions against it as necessary

I tried stalling a runaway engine many years ago, all it did was destroy the clutch as well as the engine.
Whist you can’t stall a conventional auto you can stall the current truck fitted autos, put one a high gear and set off with no throttle and try it!
If you lift the Cab a bit you may close the Airfilter.
No fire without Oxygen.
but,dont use fabriks or Paper as it will ■■■■ it in. Use a wooden or metal Plate,trailer numberplate,or your briefcase or any other hard things
The old VW Golf diesel was notorious for getting up and going all on its own. In the end VW had to do something about it. VW Part no 026 103 647 GERMANY 39 270 40 109
I have searched many times for reference to this and at last found some discussion about it here from the best part of 10 years ago:

Given the ‘knowledge’ of truck mechanics you’ve displayed on here, I agree, it does seem exceedingly lucky you’ve been in a job 40 years.

By the time you have realised what is happening, tried to stop it with normal efforts, tried to stall it, , it’s far too late to start tilting the cab

Funnily enough the MK 3 diesel Mondeo has a similar set up in that it has no oil catch tank arrangement or for that matter anything else to separate oil mist and crankcase gases from piston ring blow-by. I noticed on the car we had up till recently, the pipe from the cam cover goes straight back into the inlet tract, pre-turbo!
Needless to say, to much oil mist passed into the inlet from the cam cover will do the same thing as a knackered turbo!

Your right when there are people like you out there with years of experience.
I stand in awe.Forgive my indolence master.
2016 BTRA TRUCK RACING CHAMPIONSHIP SPORTING & TECHNICAL REGULATIONS
5.7.5.3…It is strongly advised that a Chalwyn diesel shutdown valve be fitted to the air inlet system or that the oil feed line to the turbocharger has a shut off valve fitted actuated from both inside and outside the cab to reduce the possibility of engine runaway.
Noooooooooooooo why bring this thread back !!!.. We will now ave BKING back telling us we are all useless blah blah

Haha I never realised this tripe started two years ago! I was sad when the thread died lol
you got it in one bazza ,tripe …even worse when you said it was two years ago…I’m now worried about bkings ote crap that will come back

To wander off topic slightly, why do diesel engines become addicted to easy start once its been used more than an odd time and then won’t start without it?Because it makes such a violent explosion in the cylinders combustion chamber which causes massive pressures on the piston and con rod. That is what the horrible knocking noise is you hear when its used. Think of it like using a sledge hammer on the piston crown. It apparently makes the con rod shorter each time its used thus lowering the compression ratio. Obviously the lower it goes, the harder it will be to start and so you use more easy start and so the downward spiral continues.
Never knew that, everyday a school day as they say.

I expect in practice these poxy gearboxes won’t accept any gear selection with the engine revving its bollox off, about as much use as a chocolate teapot.
Something to do with the synchros. Something something steering wheel attendants. Something something Spicer 9 speed. Something something get off my lawn!
