Why would oil be in the socket with spark plugs on a 1998 audi a4 quattro?
I have
a 1998 audi a4 v6 quattro. i recently went to change my spark plugs, when i pulled the boot off of one of the plugs i noticed there was oil on it (oil was literally dripping from the boot). i checked all six of them and it is
the same case for all. what would cause this?
