hey, i have a 96 honda civic hatch with the stock d16y7. wen i get to high rpms i hear a ringing noise. doesnt affect performance at all but i still want to know wats up. i think it might be that my valve cover is not securely fastened and wen the cams are spinning quickly it starts to vibrate, creating the noise but im not sure. also i dont have an aftermarket intake so it couldnt be that... please any help or info would be great. thanks
