Generally that has been caused by a bad pcv valve or cracked/loose valve cover. From the looks of your picture one or more of your bolts might be loose. If you have an E10 socket make sure all bolts are snug. Don't overtighten them as they don't need much torque (80 in lbs if I remember). Hairline cracks in the cover are also pretty common.
Clear out your code and see what happens.
