Possibly oil dripping from the air filter? Mine did this, lots of oil - so much that both I and the AA man thought the clutch cylinder had gone, or possibly even the gearbox. The oil was running down the rear of the filter, onto the bellhousing then looked like it was dripping out of the bellhousing.
