i have a B16A, it came from an automatic EK4, i have its lousy automatic cams replaced, i put the SiR II cams, before the change i sometimes heard some valvetrain rattling noise, after the cams, i checked the valve clearance and the valve train became a little noisier (in the 2500-3500 rpm range) some people says that this sound is normal with bigger cams, other says that the LMA of some high lift rockers are bad... but i have the LMA of all rockers checked and double checked while i was putting the cams... so.. whats wrong??? it's really a normal sound???
