I have a 39 DC that runs well but oil pressure drops to 5-6 psi when idleing. When reved up goes to 25-30 psi. I have removed all the shims in the rod caps. I only use the tractor for shows and parades. Do you think running it this way will damage the engine? Is it possible the oil pump is not doing its job? By the way this engine does not have an external filter.

Don't worry about that much oil pressure. I have one that has .050" piston slap. Knocks something terrible! Has 10 psi when cold and wide open. When it warms up the pressure goes down to about 2 psi. Zero at an idle. Has run that way for 5 years doing chores every day. I have another engine ready to go in, but no time to change it. (It is reversed with the loader on the back and it will be a 4 day job just to switch the engine).DK

Pull the strainer out of the pan and see if it is plugged. My oil pickup had old pieces of Babbit in it I don't know how it got any oil pressure.
