    Relief valve could be sticking or the spring might be weak. Is this reading coming from a manual gauge? When was the last time you changed the oil?

    I'd tear the oil pump apart. If I remember right those things have a Mitsubishi engine in them. Did it have any issues before this? Using oil or excessive smoking?

    3116 CAT or 3066 Mitsi, could be either I think?
