Faulty Fuel Injectors = Diesal In The Oil

[tonybrignell]

I have a 2006 2.5 CRD SE 5dr Voyager. Shortly after purchasing it second hand it began billowing black smoke out of the exhaust. The garage have found that the fuel injectors are pumping diesel even when the engine isn't on and its getting into the oil. They have suggested replacing them but acknowledge that there's no guarantee that this will resolve the problem.

Anyone come across anything like this?

Errrr no. Sounds like there's been bad communication to the injectors. Replacing injectors if they really need changed maybe the easy part. Finding the reason to the injectors permanently firing maybe the hardest part. 

[tonybrignell]

Yeah they did say that that would probably not resolve the problem but were unsure of what the actual cause would be

[gordy]

I'd go for a wiring fault. Injector wiring earthing somewhere.

Definitely something VERY VERY dodgy if "they are pumping diesel even when the engine isn't on"

 

I would be rather sure to NOT start with injectors - something is telling them to squirt fuel! When obviously everything should be off.

 

And just precisely what do they mean by engine not on, ignition to start but not cranked? If they were suirting all the time your engine would not start, or even crank over it would hydraulically lock.

 

If they mean they are "weeping" fuel when it's off that's a different matter of course, yes probably new injectors if the solenoid is built into them - don't know on this one.
