Is this a problem? I plan on going out in the car today, should I run the car a certain way to further gather data on this issue? |
what cam is in the motor? solid lifter? roller? hydraulic?
a pressure gauge that is showing a fluctuation, if you assume it is no fault of the gauge or sender, is the pan being sucked dry of
oil, or a massive
oil pressure leak, such as the pickup tube. a solid cam in the 385 series motors can suck the pan dry in no time if the proper restriction in the oil galley is not present. eventually it will mean rod bearing failure.
verify that the valve covers are not filling up with oil. it will make a mess but spin the motor over with ignition disabled and a valve cover off oil should be fed but not overly flooding the top end.
