No PCV Valve?
Can your car run with NO PCV valve?
I noticed both lines are being vented down thru the frame.
I took the one off the catch can and there was no PCV valve.
Any danger or will I not pass emissions?
Thanks..

I'm not the expert for the emission systems but most all know that if the pcv valve was removed, its port must be plugged of course or else it won't run worth a darn. Having the crankcase vent tubes not going into it will most likely be a problem for smog testing but only in regards to not being connected correctly. What I don't know and will venture a guess is that the PCM is probably programmed, fuel mixture, to have that pcv valve in there, therefore removing it, you would need to re-tune it to compensate. Maybe its already been done and the only way to know would be to take it to a tuner.
