I have a smoker, but I think it is valve seals because I found some of the remains in oil after I changed it. When I take off the oil filer cap it does not blow any smoke out, and it does not have any blow by that comes out in a steady stream at 2000 RPM. But I know I should check the pressure before I pull the heads while she is still running. What pressure reading in psi should I get when I put my pressure tester on her? I just want to make sure it is not the rings because I am planning on pulling the heads this week end, because I got my Ford Head Gasket set Saturday! Strait form Ford old stock with manifold Gasket included. It Will take about two week to get her done but I think My Beast is worth it. Thanks for the help on my glow plug post OIL Burners.
