    While preparing to pull the engine off the mount I am removing the exhaust and intake components. There is one bolt that seems to be inaccessible using conventional tools – the inner bolt attaching the intake elbow tube to the cylinder. Where can I find the special tool for getting in to this bolt position to remove and eventually torque the bolt back into place? Thanks for any help! Rob

    hahah! Sounds verryy similar to the IO-520's intake riser bolts.
    Grind a 7/16"(x 1/4" drive) socket down short and grind down the sides til it is pretty thin.
    I can usually get it with certain universal joints, but not all, some of those need grinding down too.
    I use a slot screwdriver to push on the socket and then the bolt head to get it started. The right size will allow you to do most of the turning then you can torque it.

    Sounds like you have been there! Thanks for the detailed feedback. I was hoping that an off-the-shelf tool already exists for this purpose, but that is probably wishful thinking! --Rob

    It might, but I don't get those fancy toys.
