The oil seal is leaking and has to be replaced, but I'm wondering if the

Automotive engines with that much crank endplay will always develop a
seal leak. The seals are designed with sipes to handle rotary sealing,
but the back and forth motions allow oil to pump past the sipes and
may cause excesive wear on the seal. Engine builders will often polish
seal contact areas on shafts to enable effective sealing and long seal
life. My WAG is that the endplay should be around 0.003", but if B & S
wants more or less, follow directions.
