Thanks for all the feed back.

I'm running 15W40 Rotella. After talking to my bother last night it sounds like there was a lot of sludge in the pan when he was working on it to get it running again a few years back.

I think I'm going to start with dropping the pan and cleaning the screen. The Oil pressure gauge could also be obstructed so will check/replace that as well.
