2010 S - Oil leaking & Filter wrench

#1
Hi all, Was changing my oil for the first time the other day and noticed oil seeping down from where the head mounts. Is this a warrenty? Warrenty ends this coming April so I dont want to miss out on something that would be covered.
Also where can i get the oil filter wrench for the cannister style? I tried the F style and a three pronged style that didnt work. Ended up using a strap wrench (which I hate)
