7.3 idi oil pressure problems
So i have a 93 idi. The stock oil pressure gauge was movin all over, after its warm if i push in the clutch and let off the pedal i loose all oil pressure. I put in a sun pro electric gauge and it does the same thing. I hooked it up where the stock switch was on top of my turbo. At stop lights i hit zero, but it still sounds fine,im baffled. Any input would be greatly appreciated.
