thank you, I do not believe it is leaking but I won't know for sure until the motor comes out.

even if you found it was leaking, it can still be replaced with the regular type. I'm yet to see a crankshaft so worn it requires the need for the repair version. The repair version just moves the edge of the seal slightly to a different spot on the crankshaft.

I suppose a taxi might eventually damage the crank not by the million miles they put on the cars but by engine hours running..
