It happened to me. It drips all the way down at the front and side to spark plugs and even further down from there. It was the rubber gasket under the oil filler neck. The dealer told me that I cannot get the gasket only, like Carson's chart show individually with a part number. At the time I did'nt know so I've got the whole filler neck for $16, not bad though.

If this is your problem, it is a little tricky to get out and insert in. Let me know if you have any problems.
