I've heard that several people have seen a 5 psig drop in overall oil pressure after adding a filter. I'm not sure the same would happen with just some tubing.
I have a '54 325 that has oiling problems, mainly from dirt. I want to take the valve gear off and hose it down at the car wash, then replace the rocker shafts and put it back together. I'm hoping to get away without readjusting the valves.
My question is: due to the dirt I can't tell how the oil line tubing connects to the rockers and block. Do I only need to take it apart at the fitting behind the rocker cover?
