    The fretting issue is mainly when you first try to turn it.  Once you build up just a little oil pressure it will tend to push the case halves apart a bit, making it easier to turn.  I think that's why Bill asked if it remains hard to turn through a couple of rotations.

    Once you have push any fluid gas oil paste the rings it should go back to normal once cleared. Also lower plugs would show evidence of this condition. Or just pull the lower plugs so all that's let is friction from crankshaft and other moving parts when you turn engine over.

    Feels like it is hard to turn At the start and then once past that point it is ok. Doesnt appear to be present everyday

    . If one suspects fretting is there a way to confirm without dissassembly?

    At what point is the aircraft not safe to fly? I am 3 hours from Lockwood.

     

    thanks

    On the day it IS present; at the first sign of the Gorilla, STOP Immediately!!!

    Then pull the bottom plugs.

    If the Gorilla disappears and/or anything drips out of the plug openings, it is a hydraulic issue.

    Reinstall the plugs and then "Burp" the oil out of the pan.

    Check the Oil level.

    If the Oil Level is extra high OR the oill smells of gasoline,  you found the issue.

    Do you routinely close the Fuel Shut-Off Valve between flights?

    If it remains hard to turn with the Bottom Plugs OUT,  it is definetly NOT a Hydraulic issue.
