It is the valve cover that is leaking a little on the passenger side under the intake stuff. It is just a little moisture that sumulates around the edges. Also, it is dripping off of the bolt a little like you said. What does that mean that the bolts weren't designed to tighten, are they supposed to leak a little like the valves on jets (when you get up to speed they all seel tight as a drum)?

Does anyone know where to get instructions on replacing that knock sensor? How critical is that? should I replace it right away or can I wait a month or so.

Thank you so much for your help so far.
