well lets see i was driving i drove up to dairy queen my car went a little nuts couldnt figure it out then before i knew it my gage shot all the way up on the temp , timing bolts came completley loose, and coolant completely drained, no hose leaks as far as i can see, fronts completley clean, it all drops off back side by the tranny, well off the tranny and i have no idea what it is, it fixed my vtec though....

 

look on the back side of the engine there is a copper lookn pipe there is a o ring on the top of it where it goes into the throttle body and also a hose that i believe goes to the heater core or something lol
