Hmm. The engine has been pretty bullet-proof for 30 hours of test flying. Then today I flew a couple of flights about 30-40 minutes each – no troubles.
Then on flight number three, after 15 minutes or so, I notice that Oil Pressure has dropped into the 50s. It dripped a little more, and eventually seemed to stabilize between 43 and 48 as I headed back to the airport. Changing the throttle or prop settings seemed to have minimal effect. As I got down towards pattern altitude, it seemed to creep back up to the high 50s and back over 60.
I haven’t had time to pull the cowl off to look around, but there certainly wasn’t oil pouring out on the ramp, and there’s 9 quarts on the dipstick.
Thoughts?

what oil transducer are you using? possibly something is impeding the signal to your engine management system.

What was your oil temperature. Oil pressure usually responds inversely with oil temperature. If you were running it hard during your flight and had high oil temperature, then the oil pressure might drop a little, then possibly descending to pattern altitude cooled the oil some and caused the pressure to come up. Just a thought.
