    Not good, has the retaining clamp bolt snapped or stripped the threads from the head?

    Ordered a new one anyway and got a new seal, will see in the morning
    Any tips on how to remove?

    Not actually done one on a Honda but there's probably a special tool like a puller, although looking at how far yours has popped out I'd imagine you won't need it, the injector pipe will probably be a pain to get back on due to how far it's been bent, best check it hasn't been fractured.

    I've heard of injectors blowing past the seal before because they've come loose but I've not seen one try to remove itself like that before. Think it safe to say you won't need an injector pulling tool on that as it's already come out. The fuel pipe should just bend back but do it gently and check it to make sure the force of the injector popping out hasn't damaged it. I'd be more concerned about how it managed to come out, has the retaining bolt worked loose or has it snapped. It shouldn't have stripped the thread unless it was over tightened at some point and previously weakened.

    Ps you really should try to keep your engine bay tidier.

    I changed a faulty injector on my 2.2i CDTI.
    My main concerns are the same as Phil's
    i.e. Has the retaining bolt snapped, or is the thread on the head stripped?
    IMHO...
    I would suggest caution when you remove the injector to prevent any debris falling into the cylinder.
    Once you have moved it out of the way, plug the injector socket with say a clean piece of rag.
    Same goes for the fuel line socket on the injector - or tape it over
    Make sure that the area around the socket on the head is clean before removing the cloth and re-seating the injector.

    If it was me, I would replace the fuel pipe. The stress from bending may have weakened it, only to fail later on.

    Don't forget, the fuel is under pressure in that pipe.

    Let us know how you get on.

    Ok so got a dry patch of weather, so quicky got the injector out
    IMAG0965_zpshxxafx9r.
    Its covered in gunk and i think some of the spray holes are covered too..... So i think best to leave to soak in brake fluid for the rest of the day, maybe this caused it to pop up??
    Gona check the bolt hole threads with the new bolt now

    I would think it 'popped out' because the bolt holding it in failed - pressure in the cylinder just blew the injector out.
    The failure is either,
    • threaded bolt
    • broken bolt
    • loose bolt
    • threaded head
    Not sure about best solvent for cleaning the injector.
    Maybe someone else can help with that...

    That's pretty dirty up the injector body, I wonder if the seal has failed or if it has been slowly lifting for a while.

    Thanks Speedy
    If spiky007 doesn't have any of that, any readily available alternatives?

    I'm not sure to be honest, personally I wouldn't risk trying to use any other solvent.

    Is there a certain way the seal needs to be seated?
     
  15. Nels Moderator Staff Team

    No worries. Just wanted to know for my interest too.

    Forgive my poor memory.
    Does the seal just look like an 'o' ring?

    You can just soak it in diesel, you'll be surprised how good it is at cleaning things. In my experience which is mostly on large engines, the injector is seated with a copper washer, sometimes with an o-ring halfway up the body.
