What pressure are you seeing now ?
What is 'normal' Oil pressure/temperature for that engine?
Has anything been done ( changed) recently?
Even an apparently insignificant a thing such as a like for like oil change will produce higher pressure on our IO-360 compared with oil that is about due for a change.
a) pressure at the top of green/bottom of red at anything other than idle power (estimate 90 PSI)
temperature 190 ish
b) pressure normally sits 3/4 up the green (75PSI)
temp normally 190
c) Lycoming O-360
previous 2 legs behaved normally
just noticed the pressure slowly creeping up in the cruise at constant RPM (2450 rpm)editted to correct gauge readings
