Right ive had a quick search and couldnt see anything similar
My mk2 8v digifant seems to have what i presume to be oil coming up through the spark plug hole. Its only wet around the second from left one and I cant see that the oil would be coming from anywhere else. looks dry all the way up to the rocker cover, just wet in the recess where the plug goes.
So, is it possible that something could be working its way out up the thread or am I just mental?
