Oil pressure problem Io-320. PA30
by Bryan Rose » Sun Jul 15, 2012 7:14 am
I noticed that the prop starts feathering below 800 RPM. I then noticed that when I slowed the engine to 800 RPM, the oil pressure is dropping to the top of the red. Increase RPM to max and pressure goes back up, but only to top of the yellow. OK, feathering issue resolved, now what's up with the oil pressure?
On startup, run up, and cruise the pressure is in the green, oil temp is green.
I removed the pressure relief spring today, it looks to be in good working order, marks on the ball bearing indicate it is sealing all the way around.
I saw Frank's issue with the cage being broken. I'll look for that tomorrow.
Any other suggestions?

You might want to bounce this one off Charlie Melot.
