As mentioned
elsewhere on VAF, I've been experiencing +/- 5 PSI oil pressure fluctuations during cruise flight recently. The oil pressure has been well within limits, but the fluctuations were new, so I've been looking into it... After we swapped fuel & oil pressure sensors a few days ago (no help), this morning, I removed the oil pressure relief valve, spring, and ball and inspected for anything abnormal. Nothing noted, so cleaned up the parts and reinstalled, and then took the plane for a test flight.
It was a bit cloudy this morning (2700' OVC when I left) so I decided to head east where the clouds were breaking up. Quickly, it became apparent that the oil pressure problem was solved. So, I kept heading east and sent a text message to my parents that I'd be landing the airport near them (KUDD) in 20 minutes.
I landed in Bermuda Dunes, and then met up with my parents. Gave my Dad a quick ride in the RV, and then after landing, I visited for a bit, and flew back home. Very stable oil pressure to & from, and the weather cleared up nicely. A nice day of RV flying!
