Do I need to drop the oil to repair the oil plug leak? If so, is it ok to re use the dropped oil? The oil has been used for about 100 miles.

Just make sure you drop it in a nice clean spot.

There ain't no gasket up there... where'd you find a gasket?...
You just pulled the cover,... not the head, right?...

Just use a good quality silicone sealant,.. like Hondabond...
Clean all the old off real good, before you put new on...

 
Yup, just a liquid sealer that has hardened.

If you go with the auto silicone sealers, the black stuff from Permabond is known to work (I used it as I wanted it to match the black paint).  You can also buy a small tube of it which is more than enough to do the plug and the head cover seal up job.

Some use red silicone sealants (shows up ugly on assembled engine) and some use copper (higher temp, unnecessary except on exhaust gaskets and shows up on engine like red does)

Hondabond, Kawasakibond etc are silver, and your engine is black, right?

If you head is silver, pick a silver sealant by all means.    

But if she is black, go with black ...

If it is the high-heat red stuff, it'll work fine.  If you want it to look tidy, just mask off the areas you don't want it to stick to; apply the sealant, assemble, wipe off most of the excess, and pull off the masking tape to tidy it up.  You ought to be able to hide most of it.  Use a black marker to hide the rest.

I used the red... remember you have a THIN layer there. Plus, I think the thin line of red that you get squeezing out makes it easier to see that you have a good seal all the way 'round....who looks that close at your engine except you???
