What dou YOU mean what pcv valve? The pcv valve is a little valve with an elbow that connects through a vacuum hose from your block to your intake manifold. It's almost like a check valve. It relieves cranks pressure directly to your intake manifold(having a catch can would be better). On my most current setup, I had the same issue. Installed a stock Type R and it was idling high and smocking, a lot of white smoke. I would unplug the iacv and it would idle lower still white smoke coming out, but not as much. It's a $4 piece, most every auto parts places sale them. That would be a good starting point..............

I thought the piece that goes through the IM was just a fitting that would easily come out. well it was previously broken so I took it out, not knowing, and ran a strait hose to the breather. I now know what a pcv valve actually is. I blocked off the intake mani, that brought idle to normal, and no more white smoke! I ordered a new pcv valve, thanks for your help! Ectune support is the best!
