Hi All
Has anyone experienced a problem similar to myself.
Travelling along the truck which id a new shape D-id animal approx. 75K miles suddenly clouds of grey smoke from the exhaust, engine over revving tried to stop it by switching off the ignition but it carried on so brought it to a stop.
sump now has excessively high level on dip stick assuming mixed oil and fuel has anyone any suggestions.

cheers guys

your turbo has had it from the sounds of it your quite lucky your engine didant go pop

It sounds like it has hydrauliced ,I know this happens to large diesels caused by a diaphragm in the gearbox sucking the gearbox oil into the engine also a blown turbo can cause the engine to "run" it's self,but never heard of diesel to get in the engine oil.

Diesel runaway. You need to check your oil levels more often and you'd have spotted this one coming. Numerous causes, leaky injectors, faulty injectors, faulty DPF regen system where fitted etc etc over fuels the motor. The excess fuel leaks past the rings, accumulates in the oil and raises the oil level until the vapour starts pumping back through the breather into the intake. At this point the cycle becomes self sustaining, faster revs creates more vapour which creates faster revs...

Failed turbo seals can cause a siphenomenon but you say your sump is diluted with diesel with leads me to believe its more likely injector related.

If you drive a diesel check the oil weekly or every few hundred miles.

Another broken pram for the list

In fairness Lemmy I've seen and experienced it myself on very well maintained trucks the last one that happened was on a DAF 105 460 bhp and I bailed out and waited for the bang which took about 3 minutes,it was replaced on warranty by DAF.

Absolutely, but more often than not you'll get a warning as the oil level rises and that doesn't happen over a dozen miles, takes a bit of time.

Fair comment

Quite common on some engines, (especially the 2.8s in paj and l200's) for the fuel pump seal at the front of the pump to let diesel into the oil over filling the sump and causing diesel overrun. For a simple test to check for fuel in the oil, get some oil out of the engine ( off the dipstick will do) and drop a blob on some blotting paper. If you have a dark blob with a clear ring round it then you have fuel in you're oil. If just a dark blob then it's just oil

3.0 Troopers suffered quite badly with this, caused by leaking injector seals filling the sump with diesel, I got in the habit of checking my old Trooper every week without fail.

Sorry to hear this has happened to your pram Taffy.

Yea it's the first I've ever heard of it on a new shape!!

Gonna be hearing more as they age and wear.

Any and all diesels can suffer a diesel runaway.

As for wear and tear, they all wear and tear. I don't think the pram is inherently any stronger, they've just enjoyed the advantage of youth, but as they also become old men they're starting to suffer similar ailments. Happens to us all eventually

I agree that all can suffer but on 77k,that's unlucky.

It is indeed unusual, but many materials degrade as much with ages as they do with mileage, and some more so with low miles as they don't undergo the regular heat cycles and exposure to preservatives in lubricants. Don't read too much into a lowish mileage.

It'll be interesting to see exactly what the problem turns out to be.

Thanks guys for the positive replies
will have my injectors checked first and will post the results as soon as I know.
thanks again!!!!!!!

Further to my problem had the injectors checked and it seems like they are all out of calibration.
I have been advised to have them replaced.
Got the biggest shock when priced up!
Does anyone know a centre where they can be obtained, or someone selling decent ones reasonably priced.

cheers

can you get them refurbed?

Hi all
Further to my recent problems with my truck.
Thanks to a very helpful Polish guy who's as keen as mustard a grafter sorted out the problem first time really good guy,
The injectors were faulty and needed reconditioning which was done at Swadlincote diesels, top guy's!!!
Dead helpful and honest felt really comfortable with the attitude and service, the turn around was fantastic too ! would recommend them to all.
So all's well that ends well, just need a little more work doing like pairing up the injectors to the ecu which has been remapped.
hopefully the above will help others with the faults I have had.

cheers all !!

nice result mate yeh new injectors aint cheap

further to the ongoing saga with my truck
Injectors have been replaced, originally the energy management light kept flashing after the work was done.
I have a remapped upgrade fitted which, when removed and the injectors coded, stopped the light flashing it is all becoming extremely frustrating as one person says it's this, the other says its that, NIGHTMARE!!!
I am still experiencing some concerns, as when I start up in the morning I get a puff of grey smoke which to me indicates over fuelling!
Anyone got any suggestions or advice.

cheers

John

Puff of grey smoke is normal, Mine does it too. especially since the decat and new exhaust

and mine

Thanks for the reassurance guy's!!!
I still feel a little bewildered with regards to the old truck. since spending money on it and not just a few quid, you can't help feeling that the garages see you as a cash cow!
Perhaps its just my paranoia.
I'll let folks know the outcomes as things progress
Once again
Thanks
