    Default injector problems

    I did a static DPF regeneration today and thought I'd look at the engine and I saw this:

    the #4 injector is soked wet. What is causing this and what can I do to fix it?

    thanks

    If its coming from the top of the injector then it'll most probably be the plastic leak off pipe. Clean around the area and start the engine and see if its coming from that. If its that you'll need a new 'leak off pipe' assembly which is about £30 or so i think. Easy enough to change.

    If it was the injector itself i would expect not to see diesel all over the top of the injector.

    A diagnostic tool gave me these readings of the fuel injection:

    Attachment 25392

    what do these mean???

    also I've seen tiny drops of fuel that seem to be coming out of the electric plug and splashing towards the injector and there are also tiny amounts that splash from the top of the injector, where the hose is connected with a clip.

    How bad is this? do I need to change the whole injector? help please!!!

    thanks for the reply plasma, it's from the top and from the electric plug towards the injector. I don't understand how can it come from the electric plug?! what's the role of the plastic leak off pipe? do I need to get only the piece in between the 3rd and 4th injector or should I replace it for all the injectors?

    it got nowt todo with when it is next due a service it is a reading in the ecu of how good the oil is you cant do 2 regens on top of one another you have todo about 50 miles between ....if the oil life is low ie it has been contaminated with deisel from doing or atempting a regen it has been known to wreck a few engines they can over heat and die .... i wouldnt do a another regen soon and if ya do might be a good idea to change the oil if you aint done it for a while .......
