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.
