RE: 390 oil pressure

You said you are getting this reading from the guage in the car. I've got a 65 Tbird that reads low at idle on the guage but there are no other indications that the pressure is low. (no lifter clatter or other noise). I'm more suspicious that the guage is just not accurate at lower rpm. The oil pressure guage is driven by a constant voltage regulator that also drives the fuel guage and temp guage. This little regulator may not have the capacity to accurately drive the the guages at low RPM when the input voltage may be lower. As soon as I increase the RPM just slightly the oil pressure reading increases immediately. It seems like this may be an indication that the voltage regulator may be kicking in the alternator voltage rather than just the battery voltage. Just a theory at this point, but thought I'd pass this along for comment.
This thread, so far...
