    Is there an extra port on the block where I can connect a gauge to
    measure oil pressure? I am try to assess a used van for purchase.
    Thanks.

    You need to remove the oil pressure sending sensor and install a
    mechanical guage.
    The switch receives oil pressure input from the engine main oil
    gallery. When engine oil pressure is greater than 27.5 Kpa (4 psi),
    the switch contacts open, providing a open circuit to the low pressure
    indicator light.
