Not a 911 isue. While driving to a track meet today , I was checking the gages as usual while driving and I noticed that the oil guage was at 90 psi ( usually at 60 psi while at highway speed and rmp, 2100-2200 @ 70 mph). Oil was changed on Wed. and no leaks any where. Every thing looked and sounded fine while driving so kept going until we got to the track. At idle the, gage was reading 60psi ?? When we got to the track, I turned the truck off waited for a few minutes and turned the key forwad but not to start. all the needles but the oil went to zero ( volts @ 9-11 ), the oil went to the 30 psi mark. Started the truck and the oil was still showinig higher psi than it should at idle. When we left the track meet, the oil gage was reading "normal" 30 psi when it warmed up and 60 psi all the way home ?????:idkidk Sorry for the long post but I wanted all the issues put in.
