But it seemed to me that the opening should be pointing towards the rear of the car, creating a low pressure area. How do you install the opening into the header? There is a little back pressure (the mufflers are straight thru) but not alot. Would changing the direction that the opening faces in the exhaust help much? What is the preferred way to evac the crankcase on a street/strip car with full exhaust? I don't really have a problem with my pcv set-up now, I just don't like dumping the crankcase (oil) vapors into the intake stream. Or is that of no consequence? Thanks!

I'm with you on this. If there's backpressure in your new line it isn't going to evacuate. I would slant the nipple towards the rear to get it to draw a vacuum & maybe slice the extension that's in the exhaust stream like a hypodermic needle. I would think that the instructions to put a bung in at 90 degrees would be for an ex sensor rather than an evac system
