I do have an underdash oil pressure gauge on it right now, only about 2 years old. I have never had the bottom of this engine apart, so I don't know for sure what condition everything is in. I'm sure it could use some refreshening, but it runs pretty good other than this. I'm not too concerned because I am going to be putting in a new engine eventually and the truck isn't being driven much right now. I was just more curious than anything about the drastic change in oil pressure.
