Question Asked: Engine Oil Pressure Gauge
January 27, 2011, 04:14 PM
Engine oil Pressure gauge-sometimes it sticks at 0; when I tap on the gauge it works and the needle responds like it should; it may work correctly for awhile and it starts up again. I recently had my transmission rebuilt and there were a couple of very small vaccum hoses replaced and after that the guage worked great. I do not think it is the gauge itself.
