    Default Oil system question, need to know asap

    im trying to figger something out here,
    im pritty sure im on the ball but just want second opinions

    bassically ive drilled all my S1 na block to accept the turbo lines (rb30)

    now with the oil feed hole ive drilled it a bit but i not sure how much is too far,
    if i was to blow compressed air into the oil feed hole and if it blows out the top of the rocker cover it would mean ive drill into the gallery......correct?

    are you using a cutting compound on the drill bit to stop swarf entering the oil gallery?

    Ben you would happen to know much on the rb30 bottom end layout?

    is the oil gallery on the oppsite side of the block? which runs down along with the pressure sensor and filter?

    have drilled 117mm in so far and its still drilling solid cast iron,
    compresed air into it and its just blowing back out, hasnt breached anything
