Oil pressure gauge suddenly goes the wrong way.
Have some problems with my oil pressure gauge on my -85 ram van. It used to operate normally, but one day when I turned on the ignition it suddenly goes towards the H symbol and beyond (engine turned off) When I turn engine on it goes towards the L symbol and stops at the bottom. This problem came one day, before that it operated normally (no reading with engine turned off, middle of the scale when idling)
Any ideas anyone? I havent touched anything under the dash or around the engine yet.
