    Default Injectors not shifting

    2 of my crush washers need replacing on my Z19dth.

    I've tried deblock oil and a slide hammer, but the injectors feel like they are practically welded in place.

    Anyone have any suggestions on how i get them out?

    Their is a way. But you'll have to be super careful.

    Put injector pipes back on and crank engine. The pressure should make them pop.
    Should really be used as last resort.

    Try tapping side to side with soft faced hammer

    That sounds dangerous and I would advise 100% against this. Fuel jets from the injectors can be fatal.

    That's why a said last resort.

    The jet will be still pointing into the cylinder. and you'll only need to crank for 1/2 cranks.

    I ain't digging m8 but I wouldn't do it at all. Take it to a garage if you can get them.

    Yeah I no mate was just saying my point. I understand it's dangerous.

    Most injectors usually break free after a bit of side to side with a hammer.

    The mech I use just left them as he said you need a special tool.

    Like I said though take it to a specialist or a mech who can get them sorted for you.

    If they are bolted down just lossen the bolts and crank over. That is what I have done in the past with no problems at all. Injection jets are dangerous only if you put you finger over the nozzel when they are injecting. If your daft enought to do that you should not be going near an engine. Sit at home and drive the tele thats the safest bet for some who would do that.

    I really don't fancy cranking the engine, not with the pressures a common rail runs at.
