PCV valve goes after the TB if im not mistaken, I didnt see that the first time in the pic above. I know on my ST220 setup the only vac lines going into the intake pipe between the MAF and TB are the front valve cover breather and the IAC line. Not sure if that even matters that much tho. Also, I have an oil separator on my PCV line and I am glad I did that for sure, it collects more oil than you would think from going into your intake.
