if you are standing in front of the car, it is on the left side, behind the head, between the head and the fuel rail nut. it takes an allen key. the thing is pretty big around. its also where you put the golden eagle ls/vtec oil line in. i somehow lost this plug, and my motor spits oil everywhere (especially on vtec).
i need the part #, or some way for my local honda dealer to understand what im describing. basically, no one there knows honda motors for some reason. i need this part asap so i can drive my car. i described the part to the dealer, and they said they wont order anything until i give them a part #, or come in (they are closed when i get out of work).

 

there is a website called majestics or something like that. it is all honda parts and they show pictures so do a search for it on google. or you could go to the honda dealer and they could print you out a picture and you could order it like that.
