Okay, so shortly after my rebuild, I noticed an odd quirk. Almost exclusively when I drive on the highway, I notice my oil pressure shoot sky high. Pegging the gauge. I know this is obviously not an accurate reading... Since the relief valve would be at ~80 psi and the filter would have blown up a long time ago at those pressures... So judging by the TSRM way of testing the gauge, saying shorting to ground will make the gauge go to the high side, would I be correct in saying I have a short to ground somewhere?
And I remember somebody saying that if you shorted the gauge to ground for too long that it would melt part of the gauge? I think it was JJ who said that.. Anyway.. I'm just wondering this because it worked fine before the second time it decided to go to 120+ psi, and now it reads insanely low. Like going down the highway at maybe 1 psi low. I figured it was the gauge being ruined so I didn't think much of it. Now i've been put probably 800 miles on it with "0 oil pressure" so it definitely would have blown up by now. So I have oil pressure.. So would the short have ruined the gauge? Or do I just have a bad gauge?
