Reply to "Oil Pressure goes up and down"

What a coincidence Ron, my oil pressure gage jumped around on me Sunday & then finally went to zero. I had pulled over & checked the oil level at the first signs of trouble, the oil level was OK, so I knew it was either the oil pressure sender or the wiring behind the gage. If my pressure were truly zero, my lifters would have collapsed & made a terrible racket.

PCV valves won't help oil pressure, 2 valves are unneccessary, one good one is enough. Pull it out of the valve cover grommet & shake it, you should hear the little check valve inside rattling, if not, replace it.

Its not likely your oil pressure would fluctuate as you describe unless you were cornering at high "g's" or the oil level in the pan was low. As long as your oil level is OK, check the gage wiring and the wiring to the oil pressure sensor on the back of the engine block first, Amigo. Make sure the connections are all clean & snug.
