could be a bad sender, should be about 30 at startup and once warmed up should settle to about 15, and undel hard acceleration it should climb to at least 60

what weight oil are you running? and I assume you've had a recent oil change?

hmm yes I'm usin 10w-30 the car was sittin for bout 8 months when I started usuin it it was the motor was clickin so I did oil change n the oil pressure moved more then b4 so after that a week later I used sea foam on the motor now it runs smothes n click happens once in a blue I'm guessin sticky lifter but the pressure now is better but still doesn't get up 2 avg friend of mine says that my oil pump maybe be messed up n also my oil pan is all jacked up n leaks lil bit of oil could that affect the pressure???

i find the gauge to be very non-indicative of how much oil is in the system, as my oil was below the dipstick and it was still reading the same oil pressure at warm idle and 3k+rpm despite it obviously lacking oil.
