OK, so I got a 98 civic ex coupe. In my state, NC, We have state inspections where they test for emissions and unfortunatly PCV valves. When I bought my injen CAI, like the instructions, i bypassed The PCV valve.But now it's time for my yearly inspection. Is there anyway to install the PCV valve to the CAI? Or do I have to replace the CAI with my stock cooling system?

 

Pics? Intake usually doesn't affect emissions.....especially if you dont have a CEL or anyhting. Pics of where you "bypassed the PCV valve" would be helpful

 

Ok ill post some tommorow.

 

If the PCV bypass is leaking and causing an intake air leak, then the engine may run rich. Does the idle speed seem too high?

 

My AEM V2s is 50-state legal, so no bypassing is permitted. Besides, the PCV has an important function and that is to allow unburned fuel in blowby gasses to return to the engine to be consumed. I don't recommend bypassing any PCV valves. If anyone is interested and has some time, I wrote an aarticle about PCV valves and trapping oil that gets past them, here:

Well I cant get a pic but I installed as the Injen instructions stated. And the Idling seems fine. I guess Ill just try to get it inspected and if it fails I guess ill have to put the stock cooling system on for a day,lol. Thanks guys

 

That's kinda what I do with my Corvette - change out the intake and oil catch can before getting it smogged.
