Oil pressure gauge on my '91

[Wendell]

Just got my '91 today and at a red light the oil pressure gauge goes to zero and then jumps back up when I get going. Is this normal?

Im pretty sure its normal, mine does the same thing sometimes.

Mine doesn't go to zero at idle (when the engine is up to temp), but gets pretty darn close. Remember, the units of pressure on the OEM gauge are kg/cm2, so the needle at the first tic represents 14.2 psi. The needle at 8 represents 114 psi.

Mine doesn't go to zero at idle (when the engine is up to temp), but gets pretty darn close. Remember, the units of pressure on the OEM gauge are kg/cm3, so the needle at the first tic represents 14.2 psi. The needle at 8 represents 114 psi.

Thanks JL, I will look at this in more detail when the oil is up to temp. I am in Dallas, where are you?

My oil pressure is pretty close to 8 at start up during cold weather ops. Drops near half-a-tick when warmed up. BTW, I mistyped cm3, when the unit is kg/cm2. My bad. I'm in WF.
