    Default 2009 S2 analog oil pressure needle oscillates+/- 5 psi between 2200 and 2400 RPMs

    When the engine is operating between approximately 2200 and 2400 RPM the analog oil pressure indicator oscillates +/- 5 psi at high frequency. This is a relatively new oil pressure/temp gauge. The original pressure gauge failed a while back. It would indicate 45 psi after the engine stopped and would only go to zero when tapped.

    Is the vibration a problem with the gauge, or is the natural frequency of the needle being forced by a prop vibration? I am currently trying to schedule someone to do a dynamic balance on the prop. There are other indications of prop imbalance (exhaust bolt wear, wear in the air box, wear in the throttle shaft).

    Thoughts?
    Thanks,
    Barry

    Falcon turn coordinators are short lived as well.

    Thanks for the replies, but this one appears to be made by Winters in New York.
