By the way, I calibrated a mechanical gauge today, got 20PSI on cranking, so
I ran the engine. It went off the scale past 100 for the first few minutes,
then gradually came down to 85. I did dome runups and taxiing. By the time
the engine was really hot the (accurate) oil pressure was 65 at about 3000
rpm. I'm feeling a little better about this. Once I get accurate calibrated
water and oil temp readings (my EM2 died) I'll do some high speed taxi tests
to see if I can get the oil pressure and temps to misbehave. I'm beginning
to suspect that the low pressure and high temp readings were erroneous.
