Land Rover Markk III Died

Hello everyone, I'd greatly appreciate some help with this matter if it's not too much trouble.

A friend of mine has a 1978 Land Rover Mark III. He was driving it today when the fuel warning light came on and the car suddenly began over revving and died. I think that the fuel pump may have come undone so how or else just died. Anybody experience something similar?

I'm guessing you mean a series 3, first offis it a petol or a diesel? second the fuel warning light coming on is normal mine does it at 1/4 of a tank, as for overrevving if its a diesel its prob running on its own oil (bad, very bad)

It's a diesel. And it's not burning it's oil.

oooo! - wheres the fuel warning light on a series 3? piccies plse.

maybe I am being obtuse - but i dont understand "the car suddenly began over revving and died" and "it's not burning it's oil"

shirley if it is over revving - that means the revs increase and died means its stopped - so is the engine increasing the revs or stopping the revs? or it stops after over-revving? - and if so how long was it ver revving before it died?

wots "not burning - its oil" mean?

my one is in between the clocks at the top

bugger - i got a hole there. Mite have to check the squirkits

its possible for a diesel engine to run on the oil in its own sump via the breather system direct into the inlet manifold therefore flat out until dead the only way to stop it is stall it or decompress it

and it aint good news when it duz it - either.

its more common for turbo D engines to overspeed when the turbo oil seals let go, but theoreticly it is possable. if it picks up some oil and starts to overspeed it has been know for the engine to draw the oil from the sump via the breather

its not theoretical i have seen it happen engine was in bits

before - or after ?

the only ones i have seen/experianced go are turbo diesel engines, on cars some ecus you can recall the highest rpm the sensors have seen, i saw 13,000 rpm from a VAG 1.9tdi that was a new engine where a mechanic hadn't checked the old turbo 4miles on the clock for the new engine boom

Right, I was told some more info and it might help
1: The car had used all it's diesel, all, dry as a bone.
2: It was given a quart of petrol from a Seat Arosa (Irrelevant yes)
2: It started, then after two or three seconds it began to rev like a mo fo, when the owner yelled to his brother to clutch it. To no avail, the car just conked out.

yer put petrol in a doosul?

its possable the petrol has detonated and blown a hole in the piston/s is petrol doesn't like the high compression of the diesel engine

I wasn't there so I didn't. SO it could have been that the engine has now blown?

yer catching on fast..
doosul is compression ignition.
doosul has a higher flash point than petrol
doosul injuns have a higher compression ratio to allow the air temp to get high enough to ignite doosul
petrol will ignite much quicker than doosul
which means that it will ignite while piston is being driven up yer bore
so yer have injun trying to push piston up, and ignited petrol trying to push piston down. something has to give.

and if that int enough petrol burns hotter than doosul aswell.

Yes, and as an interesting sidenote, you can extinguish a cigarette in diesel but not petrol.

Anyway, I'm having a look later this evening and will report back.

When i put my 2.25 diesel in i ran it with the oil bath air filter connected but sitting on the wing it fell on its side and engine sucked oil out of that, i donth think this could happen with the filter situated in its correct place!
So this is probably of no help!! But an intresting tale!

also chucking a gallon af petrol in the tank every 10-12 tankfulls (in a full of doozel) will help keep the injectors clean
