Yes, These are the drain holes for the spark plugs. There must be oil ingress into the spark plug area which is/was sealed by the valve cover gasket. You will need to remove the valve cover (not trivial) and renew the culprit (or just the whole gasket if it comes as one). The spark plug recess will also need cleaning. TBH it sounds to me that this job should be done by a competent mechanic rather than yourself. However, to verify, simply remove the tank and unplug the suspect spark plug socket. It should be covered in oil.
