I have a 1st Gen Procharger kit with a P1sc- 1 head, I have a catch can between the PCV and the manifold. There is a hose going to the air box from the passenger valve cover for fresh air, can I just put a filter on that line to stop oil from getting sucked into the air box and dripping on my driveway ?.....Wife is pissed !

No, that line should be seeing vacuum under throttle and putting a filter on it will just create a vent, not vacuum. Hit up Mighty Mouse and he can help you find out why you have so much blow by and come up with a way to address the issue.

The easy way out is to put a catch can in the line from valve cover to filter.
