Probably what happened was the seafoam cleared the garbage keeping the seal from leaking heavily and it's now able to flow freely.
A crankshaft seal is not very expensive in itself, less than $50. The labor, however, will be pricey. I would venture to say it is booked at about a seven to ten hour job. At an average of about $85 per hour, you are looking at around $600 to $850 in labor, without a labor guide in front of me.
