    Exhaust manifold 02 install

    I know this has been beat to death but I am about to drill my 2005 manifold for the o2 sensor.

    I am going to use the 12mm to 18 mm adapter that I purchased from innovate so I can drill a smaller hole to lessen the chance of hitting the water jacket.

    My question is do I still drill the center of the boss area on the exhaust manifold? Not quite sure where the waterjacket is that I am trying to miss drilling into.

    If your going to drill a smaller hole, and have extra room on the boss.... I personally would shift the hole as far away as you can from the water fitting!
