The M20 engine commonly leaks oil from about every place it is conceivable that it could leak oil from!
A M20 engined E30 with no oil leaks is a rare beast. You'll have to narrow it down a bit for us to be able to suggest the likely places.
Whining diff is also very common, and, as long as it isn't too loud, is nothing much to worry about at the moment.
They happily go on whining for tens of thousands of miles.
