Hey guys

I've noticed a (long) while ago that there is oil all around the waterpump, on the right side of the bike. Could it be a worn out oilfilter gasket? I havent changed it in a while but it looked ok last time I did my oil change. I cant say for sure its coming from the filter but theres nothing else there that would spit oil out.

Here are a few images, sorry for potato quality
