LOL, not to sure what the fuss is about.
If you have a leak, it must be fixed!
Just get it fixed or your motor will fail due to oil starvation, especially if its leaking as bad as you say it is.
I don't know why you would rebuild it for the sake of it, unless you were planning on some major mods or power increase. (Or you are loaded with cash, in which case it shouldnt worry you getting a oil leak fixed)
