Last night I finally got a chance to fly after a month tending to other things.
Plane start fine and all was well at the run-up, but as I taxied to take off the EFIS squawked High Oil Pressure. It was at 40 lbs. Usually it runs around 23-26 lbs.
I turned on and off the electric pump and that made no difference. I ran the engine up to 2500 rpm for a minute (it helps with fowled plugs). The pressure came down to about 32 lbs (in the yellow). I ran it up again for another minute and the results was 29 lbs.
I proceeded on my flight watching the fuel pressure. After take off the pressure dropped to 27 lbs.
My questions are:
1. What happened to cause this.
2. What should my pressure setting for normal operation be on an IO-320?
(what to set as the lower and upper limits on the yellow and red zones).
