I was wrong,thought it would lock up pump,guess gears were soft enough,to let it through,I would check distributor shaft,gear and replace oil pump shaft.
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.
