I've been considering venting my PCV for a while now, well while replacing a dry rotted vacuum line connector I broke the PCV elbow. In a panic I bought the following at advance: spectre breather (yeah JDM), doorman hose plug, doorman universal PCV grommet. I think it works pretty well, The breather took a bit of a push to get into the grommet I put in the valve cover but it seems pretty safe and leak free. I'm just looking for someone to say JESUS NO DON'T DRIVE THAT! before I make the 2 hour drive back to school.
The plug in the air intake boot is slightly oversized, threaded, and tapered, so it shouldn't back out or get sucked in.
