Well I know its the passenger side, extremely loud. Not sure if its on the header to cylinder or the header to collector gasket, and special way to tell which part its coming from, kind of hard to do by ear :eek:

if its the collector gasket u would hear it get louder whne you get under the car...or put your hand around it w/o getting burnt. You should feel it leaking. If its not there, then its your header gasket!
