oil pressure varry's while driving
I have a 2001 2500 and i am having a few problems with it, first is my oil pressure is all over the place, i have a set of glow shift gauges one of which is a oil press gauge and on start up it jumps right to 100+psi then as it warms up it goes to around the 80 mark. After a short drive around it will read only about 20 psi at an idle and as soon as i touch the pedal it jumps to 100+ again. my gauge only reads to 100psi so im not sure what it jumps too but it jumps instantly. When driving down the hyway it will usually stay around the 80+- mark but it will constantly vary from 70 to 90ish. I am sure the pump is on the outs but am wondering if i need to replace or check any other components first. O ya there is also a whining sound coming from the oil pump area and whines louder when revved up and down.
