Oil System Pressure

Yeah, unfortunately Bernie, its both.  The gage drops down to almost
zero.  Usually when I hear the alarm go off, I am alarmed and hit the
gas pedal pretty fast which brings the pressure right up.  I always have
adequate pressure at higher engine speeds although it seems like it used
to be pegged at 5 bar over more of the speed range.  This only happens
on the hottest days after idling for a few minutes.  Maybe internal
leakage in the pump?

"M1 will do it every time", he said kiddingly.  The lube system only has
over pressure relief valve, at about 50 or 60 psi.  Does your
alarm you or the low pressure warning system?  Low oil pressure means
pump capacity, unrestricted flow.  That's good.  Low pressure is good,
pressure is bad, watch for your idiot lights, not the gauge.
