I tried to take my 93 Cobra through emissions in Virginia the other day for the first time in it's life (used to be a FL car). They failed me, saying the pcv valve was venting to the air. I'm not too up on pcv valves or where they should vent, so I was hoping you guys could help. I've attached a few pics to show what it looks like. From what I've read, it's not stock, so I'm not sure what's up with this thing. Help is appreciated, thanks.

Hook it up to a vacuum or intake, I think it should pass.

the valve cover breather will have to be replaced with a closed cap... at least for the test anyway.
No way that will pass...

Forgive my ignorance, but where would that hook up to the intake or vacuum line? I'll replace that breather too.

the vacuum line should be hooked up to the intake pipe (after your maf & before the inlet of the blower). i would use some type of good oil separator inline. or you can hook it back up to the throttle body for the test, (but dont go into boost this way)
