propeller feathering while ground run

[Skymasterdriver]

I have seen them go to feather because they get to hot, running a fuel calibration if ran several times it may have gotten hot and lost oil pressure do to get oil so hot it lost its velocity

Sounds like a smart move. Could have anything in any of those passageways. Don’t want to find out with a starved bearing. Check oil cooler in case it also got contaminated. Pushrod tube seal is easy. Been there. Get the tool for the pushrod spring and it’s a snap.

Thanks guys for the info. I'm pulling the engine today and installing the old one until I get the overhauled engine checked out.
Appreciate ALL you comments/suggestions!
