    just spray the area around and above it with brake cleaner or degreaser. If it is the oil sensor leaking; they usually leak where the brass and plastic meet or around the electrical connector; there's a crack in the plastic portion of the sensor.

    Good Luck.....

    Thank you, more or less I was asking if this is where the mess "usually comes from". I have the cowls removed right now so easy access.
