(T) Oil leak somewhere lower cam belt cover

Last week changed the oil on my cinq sporting and noticed there appeared to be quite a bit of oil on the cam belt covers (lower half) particularly. Never noticed any oil on my drive, but the oil pan at the bottom was also a bit of a mess.

So my questions are
- if there is an oil leak is it going impact on the (recently changed) cambelt?
- what should I be looking as needing replacing in that area to stop it? (Or is it just going to be a case of getting the degreaser out and having a go with that and hoping?)

(Head gasket has been done, BTW.)

The oil will eat at the rubber of the belt probably, so best to tr and clean it off, not sure if that will do more damage though. If its only recent, cleaning it off will prob be fine.

Could the sump gasket be no good? Prob get more oil if that had gone though.
