Help troubleshooting potential causes of crankshaft failure

[sonex1020x]

Hey everyone. I could have sworn my Aerovee #356 has a red prop hub. I'll have to check next time out to the hangar. And, just curious, of those of you that have had a crank failure, was the oil gallery restrictor plug removal modification done to provide more oil to #4 bearing? And, have aerobatics been done? George.

Seems odd they no longer require the oil hole in the bearing to be enlarged.
