I'd hook a mechanical guage up to confirm those numbers before doing anything more.

You can run engines quite a while with low oil pressure but eventually they will blow up.

I remember one of my dads friends had a boat with an ancient pair of Cummins na V8 diesels in their. One had no oil pressure at idle and only a bit at speed. But it ran for almost two seasons before it spun a bearing. The owner wanted to repower the boat with modern diesels and decided to wait for it to blow.
