Changing valve cover gasket

Hey guys I just got my boat back to Canada after a long 2weeks of waiting for the dealer to find the trailer titles. Anywho I was cleaning everything out and noticed the bilge had oil in it was concerning. So I did some investigating and it seemed it was coming from the valve cover gasket don't know if it's a common problem but I figured I'd post some pics it was really easy
