my oil pressure gauge needle stays on top of the "m" all the time. When I turn the engine on in the morning the needle is in the red area on the gauge and when the engine cranks the needle rises until is rests over the "m". It doens't fluctuate as engine speed changes though. Is this right?
It is an On/Off swich as stated before. It won't flucuate (sp?) unless you have very little or no oil preasure. Since the oil preasure is the "heartbeat" of the engine I installed a autometer gauge on the piller.
