Alright i've been searching for days and call me stupid if you want b/c any help at this point will be apreciated. But anyways I have a JDM ITR motor in my coupe and failed emissions. I got a great deal on the motor that is why i got it otherwise i prolly would've gott'n the b18c5 (USDM). I took it to honda and they said i have a PCV failure. Now here is my question. The PCV valve that my car contains is Japenese. Does the failure mean the PCV valve is bad or is it failing b/c it's japenese. And does the U.S. PCV valve make my car pass emissions? Before i took the test i had the spark plugs changed, the oil changed and I have an ITR exhaust on my car and JDM ITR intake manifold. Anything that can get me through this test and pass will help so PLEASE don't hesitate to post me. Also i'm going to try that garunteed to pass emissions luqid they have at Advanced Auto and maybe change the PCV valve. That is all i know that i can do. I don't want a USDM ECU and i definitely don't want to change my intake manifold to USDM. That'd be too much. Any more info you need to determine how i can pass just let me know. Thanks guys and as always you all are the best!

 

Just change the PCV valve and see if it helps. The valve is fairly inexpensive, actually less than 5 bux. When they go bad, they just allow oil to exit the motor via the exhaust.

 

Thanx man, anyone else? Just to make sure that this thing definitely passes
