I've not long had my Golf GTi 8v and when I first got it home the oil looked clean but was low, so I topped it up to just under full and I've just checked it this morning and its back to where it was 800 miles ago

Being a old golf I thought the smell of oil was just normal but obviously its being burnt up somewhere, there is a small leak from the distributor but it is small and looks like a new seal will fix that. Where else should I check? There does seem to be some smoke out the back so I'm guessing it could be the piston rings?

Also if I accelerate hard in first gear theres a creaking noise, my ideas are the driveshaft somewhere or an engine mount?
