Hi, I recently experianced a run away engine due to excessive oil levels in the sump. This was caused by diesel fuel entering the engine oil via a leak in the fuel injector seals. I had a manual so was able to stall it but not before the huge detinations caused a crack in the cylinder head. Anyone aware of this kind of fault or any experiance. Its cost £4000 to rectify after 2 dealers fixed it through experimentation.

Cheers:(
 
I,ve just swapped my isuzu trooper 3litre for a TD5 because of the same problem,the seals on the injectors leak diesel past into the oil and then the engine just revs itself to death....usually costs around £4-5000 to fix although isuzu have got a recall campaign to rectify the problem. I hope that landrovers aren't gonna start doing the same thing :eek:

I had this problem on a works transit again it was a ford problem but while we were trying to stall it we shattered the gearbox so a new engine and gearbox was on the cards :)
just glad it was a company vehicle and not my own
 
we have an astra van at work with an isuzu diesel and it does the same when ticking over. we were told that its pulling oil into the turbo.

that i can understand but the bit i don't is why it would 'run away' because of too much oil in the sump. can someone explain that please?
 
Hi just to explain, the oil gets to a level where it gets thrashed around by the crank and forms a mist etc, this and the excess oil level is enough to cause the oil mist to be drawn through the crank case breather then into the air intake system, on the td5 the breather is up stream from the turbo so before you know it it gets forced through the intercooler and this is what runs the engine, very scarey, lift off the throttle and it keeps going, turn off the ignition and it still keeps going. The garage who got it going again reported that the intercooler was 3/4 full of oil. I have heard of diesels running on their own oil when the engine is knackered and it gets sucked past the rings but this has only done 49k so that is not the case.
 
a good reason why never to fill your lube oil past the dipstick max mark.
engine manuals give strict warnings about overfilling.
 
It also used to happen on tdi's when the head gasket blew into the pushrod holes,the excess crankcase compression would stop oil returning to the sump.Then it filled the breather up,on out to the intake hoses and you have a self feeding bomb.Early diesel vw golfs were quite good at it as well.:D
 
rather than putting it in gear and against a wall to stall it, maybe better to smother the air intake with a rag or summat.
easy with a snorkel eh?

maybe the old ways were best. feeding the breather pipe into a plastic/tin container. or into the atmosphere.
(just my thoughts).

I tried the car into wall thing before, and I managed to take out about 12ft of 6ft garden wall, placing my car in the persons back garden. Oooops!
