yea, i listen to my honda friends, and consult with them before doing ANYTHING. if its not leaking, why would you crush it? do you know if its leaking? 1g or 2g? if ur 2g, u cant crush the 2g bov because to my understanding theyres alot of plastic parts, do an intake leak test, if it leaks, crush it in a vise while testing it with a mightyvac making sure not to crush it too much. i wouldnt listen to you friend, im sure somewhere he heard about crushing a bov, figured hed try to sound intelligent and tell you what needs to be done.
