About the possible groove in the crankshaft....

There are kits available that have a new seal and a sleeve that is forced onto
the crankshaft, the sleeve creates a new surface for the seal. The sleeve itself
is tight enough to the crank that no oil can leak out between the sleeve and the
crank. The sleeve has to be driven onto the crankshaft with the appropriate tool
or pipe. There's no need to worry about damaging components in the process of
driving on the sleeve, it's tight, but thin metal that allows it to stretch
slightly to conform to the crankshaft. I have personally seen these kits used
with great results, unfortunately I can't remember the manufacturer's name.
