Slider 2828 has already recommended the pcv be attached to the intake pipe via a catch can (see my quote above). So it's not such a big leap to use the pcv outlet as the main source of crankcase ventilation for those that don't want to or can't weld a bung on the top of the cam cover.

Unless I'm mistaken, the S14 cam cover uses a side outlet for the connection to the intake pipe and this is considered to be a good system, only it's on the other side of the cover to the PCV.

Just give us rational reasons that this would not work, not emotional ones. For example I've realised my suggestion to use the factory oil seperator as a catch can for the PCV would not work because there is no way to drain it of oil if you use the bottom inlet for the PCV inlet and the top outlet for the hose to the intake pipe. So stike that out for a start.

Foreignmuscle: if you've tested your PCVs with a boost leak tester and never had one leak then either you are very lucky or I am very unlucky. Countless people will tell you that many of these valves leak even from new. I'm talking about the S13 OEM metal type.
