Ive got the leaking oil thing too, I Think the pcv thing is leaking thou, cause its really oily sometimes. As for the odd rev, have you checked for major vaccum leaks, like the intake hoses coming off or something? Also look under the hood, And see if that vaccum thing that is next to the idle screw isnt doing it. BTW, what does that thing do? (the thing with the filter) I plugged mine into a vaccum line, And now when i left off the gas it doesnt annoyingly stay revved for a second. But it didnt really seem to change anything else.
