Re: Smoke from oil cap?
U r right. Engine runs fine w crankcase venting from rear draft tube. Don’t think anyone takes issue w that. Some just prefer a cleaner underside of the car by not letting the draft tube spray vapor laced w dirty oil underneath while rolling down the road. I have put pcv’s on all my pre pcv cars & noticed they’re a lot cleaner on underside when working on them, JMO.
