it's hard to tell from the picture. can you clean it up and put tons of after run oil in the engine, if the oil is coming out between inner race of bearing and crankshaft, you might have a bad apple that slip thru the QC. If oil is leaking out of the between the inner race of bearing and the plastic sheild of bearing, you got a bearing problem.
If there is no immediate leak or no sign of leakage in an hour, it's probably from running too rich on the bottom end.
