    Fuel Injector removal - 1985 4000S

    Question:

    On a 1985 4000S The Fuel Injectors are loose and seem to be leaking.

    Yet, even with a hard pull, they don't seem to come out.

    Any tricks or experiences anybody?

    You need one of the pullers here

    shown in operation here

    Some protect their valve cover from damage with a flat piece of wood or
    metal. ;-)

    later,

    If you're any damn good at it, a Big Damn (TM) Screwdriver will get them out
    quite nicely in under 2 minutes for all five. I found the Official
    Factory-by-God VW/Audi 'puller tool' that Jim Blau lent me to be totally
    useless.

    I had trouble when I tried to remove one a long time ago in my KV-engined
    coupe quattro. I managed it just recently (I'm stripping the engine for a
    rebuild) but the thing that made the biggest difference was rather than
    using one pry-bar or screwdriver, I used two on advice from my mate whose
    workshop the car is at. This evens up the pressure to pull the injector out
    straight rather than at an angle. With two standard pry-bars the injectors
    came out without too much trouble. They were also quite loose in their seats
    prior to removal. The car is 1986, around 270,000 miles on it.

    HTH

    The injector O rings harden with age/heat making the injectors loose in the
    head inserts and also making the injectors hard to get out. Make sure the
    inserts are tight in the head when you've got the injectors out and replace
    the O rings.
    I heard a story of the O rings getting so hard/tight that the head had to be
    removed and bolted to a railway sleeper, then a long pry bar used to remove
    them.
    Replace them every couple of years to avoid this problem.
