I've searched and cannot pin-point how to appropriately term this oil leak...see pics below. It seems to seep out some from underneath the screws...can I just unscrew these and replace whatever seal it needs? Or (and this is a long shot) are these somehow spring-loaded and tied to the vanos head units somehow and require more detailed attention? seems like # 4 & 5 in the depiction below are what I need?
