If it is approx 7 to 8mm dia it is possibly a crank oil passage plug. If the crank was repaired and Heat Treated during the rebuild, the plugs visable on the Rod journal end Counter Weight side will loosen up and fall out. They should be tapped and replaced with pipe plugs. Check and see if the rebuilder had the crank Heat Treated.

Best regards
Wouldn't the plug in the crank be steel instead of aluminum?
