Were was the spring bolt located..I have a similar issue..and I just can't pin point tMy god all you guys were right haha. It was a spring bolt not compressed all the way. I just thought it was impossible to be an exhaust part because it only made a sound specifically at 1700, and 3000, not even in between. Thank you guys! If you don't know, 8thcivic fuhggin knows.
