Why do you think it's bad. Oil pressure light, or gauge?

Your oil pressure is dependant on the restriction put on it. Your pump could be producing enough volume but if you have a spun bearing or your bearings are the wrong size you will have low oil pressure. How many miles is on the oil pump? Have you checked clearances of the pump?

 

i havent done anything at all yet
plan is to test the pressure with a mechanical gauge sunday and go from there
how would i go about measuring the clearances of the oil pump

 

Take a look in your manual. They have pictures and everything!

 

What is the engine doing to thing you need a new oil pump. Are you burning oil? This could also indicate a spun rod bearing since an excesive amount of oil is going past the rod bearings and being flung up to the pistons past the oil rings and being burned.

 

everytime i spin a bearing my oil light comes on at idle
