I wanted to put a breather cap on my oil filler neck but my strut tower brace is right in the way. Would it be ok to cut the oil filler neck with a pipe cutter down alittle to get the clearance I need? I need the oil filter cap because if I hook up the stock hose (that's on the oil filler neck) to the intake my car idles funky and goes up and down like a roller coaster till it finally cuts off. Right now I have the hose disconnect and hanging and the hole to the intake blocked off.
