You check oil pressure with a gauge screwed into the spot where the oil pressure sender goes. Compression is check through the sparkplug holes. (you can have lots of one and not the other) A bad sender is sometimes the problem, but if your oil filter is orange colored and the brand rhymes with damn, then a fresh oil change with (I think) 30W oil (not sure if they wanted detergent oil for that old or not?) and a better filter would likely save your engine.

My 58 Rambler American has low oil pressure after it warms up (at least the low oil pressure light comes on once the car has warmed up). I have not checked oil pressure with a gauge through the spark plug holes, but that is the next task. My question is, if my pressure is indeed low when warm, what is problem? Someone told me either bad pump or bad bearings. I am hesitant to think that it could be bad bearing as it runs really good. Bad pump is something I may agree with. I will first check the pressure on the cylinders, if they check out ok, then I will look at the sender, then the pump. It could just be a bad sender, maybe? Or old/bad wiring to the gauge? If it is the pump, where is the pump located on this engine? Is it behind the oil pan like other engines? If so, how do I get it out to replace it? I am hoping someone can help! Thanks!
