Can't figure out this damned oil leak

A few thousands would be hard to see. and can't see the the seal not being able to seal that. But if the seal to crank was off enough to be the cause of the leak. It should be obvious to the eye.

Is this a boosted eng? is there crank case pressure? Is the thrust bearing loose cause the crank to go back and forth? Is it possible that the seal is rubbing on something, when its installed. Harmonic balancer rubbing on it, or the oil pump???

This is way off field but its it possible that you have a crank seal that was meant for a speedy leaves but didn't come in the box?
