Oil Pressure

[eze2bme]

Ok ... here's my delima ... I just changed the oil and filters on my 671N's. Before the change I was getting pressure readings around 65 psi at cruising speed. After the change I get this reading on the port engine but only about 45 on the starboard ... although at times it will go up to 65 but then drop back down to 45. Oil level on the dipstick shows FULL ... at least at same level as before change. Any thoughts?? I'm using Shell Rotella T40 ... same as before. I'm sorry to say that I didn't check the gauges on the flybridge ... I'll do that next. Maybe that gauge or sending unit is going bad???? Thanks for any feedback.

It could be just a loose connection on the sender. I had the same indications with my water temperature sender and that's what it was.
