    My 400 sb oil pressure is running as high as 60 psi on the highway. Does this seem a little high to anyone? My gauge runs between 3/4 to 4/4 all the time. I have also noticed that my oil pan seems to be leaking a lot more now to. I was thinking high oil pressure might cause this. Where does your oil pressure usaully run?

    Thanks,
    Mike.

    When it is cold it is about 40 and hot is about 30psi.

    Mine will hit 60psi when warm. Is this good or bad?

    60 sounds high when warm...does the motor have a high volume oil pump or anything?
