    Default petrol injector leaking!!!!

    Hi to all,

    Got a 2005 sri with z22yh. Recently had cam chain go , head of skimmed and new valves fitted etc. Runs perfect now apart from the injector nearest cam chain end is leaking . The injector would leak and gently hiss out fuel under pressure. My spanner man has had it back and played around with it. It now dosnt hiss anymore but still leaks intermittantly. Do these injectors have seals that can be easily replaced or is it a head off job ?
    Any tricks or tips boys ??

    Cheers
    Mollers

    The injectors sit in a plastic cup in the block, the cups have an o ring which can easily be damaged if the cup is not seated correctly when the injectord are pushed home. I had to replace two of mine a couple of years ago.

    sorry to hijack your thread but my cam chains gone i believe, how much did it cost you to get it sorted, (head skimmed, new valves etc) mines a z22yh also
