I don't know if it is a new thing or not. I brought the tractor down from Michigan to Kentucky from my fathers farm. He had alziemers and was messing with the tractors with a cutting torch so I got them away from him. Dad has since passed away.
When I brought the tractors down they all ran but I did not run them very long and just put them in the shed. It has been several years now and I just noticed that the oil pressure was not there so I don't know if it was that way when I got them or something happened when I started it up. The engine seems to run fine and nothing has seized up yet. I have pulled the valve covers off the side of engine and poured oil all over the valves and rocker arms when I ran it. I have not run it for any length of time but still no oil pressure.
Thx for your advice.
