    I have to replace the front Camshaft Gear/sprocket(the one that the Timing
    Belt rides on) for a 99 Sonata 2.5 v6. How do I get the bolt off?... The
    old gear, all the spokes broke, but I was able to mark the timing on what
    is left. Is it mounted on a gear for the cam? I didn't want to do more
    damage, so I thought I'd check.

    Would the dealer have this item in stock, or am I better going to

    By the Way, I broke the sprocket/gear accidently while I was trying to get
    the crank pully off for my timing belt project (I tried air wrench, and I
    ended up puting something between the spokes on one of the upper
    gears(sprockets) and the spokes broke on man!) So, everything is
    back together as far as I can go now (timing tensioner, water pump, idler
    and tensioner pully... water back in the radiator, etc...) I just have
    this one thing to replace now before I can finish up. I know, stupid
    move, now I've learned.

    Do I need to pull the cylinder head in order to get the old sprocket off/
    and install the new one? If so, do I need a new head gasget to put on
    when I bolt back up?

    OK, per the repair manual, I would have to remove the valve cover, and NOT
    the whole head (am I right in reading it that way?). Would I have to
    replace the valve cover gasget if I do this?

    When I install the new sprocket, How do I know where to align the timing
    mark (it is in a certain position now). Will the sprocket only fit on the
    end of the camshaft one way (in a cerain timing position?)

    Or can I get away with not taking the cover off to replace the
