Re: Low oil pressure?
Steve & Liz Jackson
James, I had one of my 390’s loose oil pressure to the point of it knocking, but still running. I was racing it at the time, so I assumed I spun a bearing. When I pulled the motor, I found all bearings very good shape. Then I found the rear camshaft freeze plug had come out. This allows the pressure drop. I had put “press in” plugs when rebuilding it many years ago, but now I know better and use a “screw” in style, with locktite! Just another thought.
