If the oil is definitely coming from the alternator cover then it is one of three possibilities.
1. The crank seal behind the rotor.
2. The bung on the oilway below the crank seal.
3. The mating surface of the crankcase.
If it is 1. The engine does not need to be stripped to replace the seal as there is an alternate seal available. Part number 93101-29166. Easily replaceable with the rotor off. It does require a special sealant when replacing it. Should take a good mechanic less than 2 hours.(Biggest issue will most likely be removing the rotor) Remove the cover and tie it up, remove the Rotor and be careful not to lose the woodruff key. Lever out the seal, it has lip but surprisingly easy to remove, careful not to mark the crank or the crankcase. Clean up the area with some fluid that evaporates quickly but does not leave residue. Smear a little sealant on the seal and housing. Push the new seal in squarely. Use a deep socket or something which is deeper than the crank end and as close in size to the outer edge of the seal as possible. Replace woodruff key then the rotor. Replace the cover the rotor replace and leave it over night for the sealant to cure.
If it is 2. clean all the paint of the area, score the area lightly and apply some JB weld to the area. leave it for 24 hours to set .The area will need to be spotlessly clean to ensure a good bond.
If it is 3 do the same as 2.
2 and 3 can happen from a trip down the road on its side at speed. :-)
