I believe there is a valve behind the oil cooler adapter actually in the block that is the oil pressure relief valve, does anyone know what are the symptons are if it has trash in it or for some reason it doesn't seal good or the spring is weak. Still fighting oil pressure issues once the motor is warmed up and you travel at highway speeds for a while then as soon as you slow down for stop and go traffic or rest stop, oil pressure comes back up to safe levels (35-40) and stays there till you get back on highway for a while. I read awhile back that the Olds pressure is after it goes through the motor and not just as it goes in so it seems that any pressure after it makes it's way through is good. Motor runs great otherwise and I am running a mechanical gauge and napa filter with 10w/40 oil. I have actually soaked the pan with cleaner and used a vacuum pump several times and tried to pump any trash out and could not pick up any sludge off of bottom of pan. Any and all thought and ideals would be appreciated.
