Oil leak on engine gasket!?

Could you point out where exactly the leak is? from the pix, I'd guess a leaky valve cover gasket, which is not too difficult to remedy.

just looked at the pic with the arrows. I don't think you have any issue. Looks more like normal under-hood grime mixed with a minimal amount of oil that seeps through that gasket over time. No biggie. Clean it up and check it again in a week or two. If it's still clean, you're good.
