    So I changed the turbo and charge air cooler, and back head gasket, put new oil and filter on
    And on start up I'm running 40psi oil pressure? What should I check or is their away to check the sensor? I'm rev it up it won't go over 40 but will drop to about 30psi

    Thats in spec. Low psi, high volume is a N14. Been a few years. I think low level is either 12/18 warm at idle. If she does 35 psi wide open. Your good. Constant psi engine.
