Help with 2008 BMW 535xi Oil Leak

[stumpmtsr]

Hello everyone. My Bimmer has 209K miles on it and I just started getting a 3rd cylinder misfire. I have installed new spark plugs and coils and will be getting new Fuel injectors...the 3rd spark plug was wet and smelled like fuel. I have attached a video that I have a question about. What are the circle "Plug" areas to the top left of the coils? There is oil in them and I don't see any leaks. I would assume it may be from the valve cover, but I can't see where it's leaking from at this point. Has anyone seen oil in this area like this? I appreciate your time and help. She's been a great car and will do whatever it takes to keep her that way.

Thanks everyone for the reply. Once i removed my new spark plugs (Have been in a few months) I noticed my second spark plug had a lot of oil on it. It is definitely a valve cover issue. The last time the valve cover was replaced was at 154,547 miles. I have about 209,400 miles on it now. We'll see how bad it is when I get it apart.
