If you still have filter cut it apart and may find clip in it or in a oil galley somewhere since plug was gone under main cap. if not planning on it I would clean all galleys well replace cam bearings because trash could be in grooves behind them and no other way to remove it or check for it and try to find clip,you had metal go through bearings but not the whole clip,what has went through there is probably not much more than .005-.010'
Probably can polish crank have to be sure metal isn't raised on sides of groove,if grind crank .010-.020 more probably will still have some of groove left, groove there is about the same as groove in bearing,some cranks have grooves in rods and main journal for oil.

All good advice, thanks Mike. I would love to be able to stay with this crank but I'm a little leery. The rod journals are already -.030, so do you think the groove would be a weak point?
