Do you have any other leaks/wet spots?
There are a bunch, but probably not something to do unless it's leaking imo. There is the distributor shaft o-ring and the oil cooler o-ring(s?) under the oil filter, and of course the oil pan. Deeper in, when doing the timing belt, there is the crankshaft main seal and camshaft seal, along with the o-ring and seal for the oil pump.
