    2.1 406 diesel.has a funny intermittent knock but when you cranck off
    one of the injectors then tighten it up again its stops for a while?
    I've been told it could be air in the system but it's done it now for
    about 850 miles! any one got any ideas what it could be??

    Sounds like a duff injector spraying too much fuel in causing engine to
    knock with excess fuel,
