Is it possible to connect a PCV valve with a single turbo setup?
 

Hello guys,

1992 JDM FD.

I know the top nipple on the oil filler neck goes to UIM... However, where can I connect that bottom nipple? There is no other nipple that big available on the UIM...

To the turbo intake or just leave it open. You should be using a proper catch can with a single turbo anyway

i just tapped a fitting on the pipe in front of the turbo, super easy. the oil change place overfilled the oil, so i can confirm that its working, lol

plan B, if its an FD you could probably just run the PCV from the oil filler neck to the upper intake, a stock FD actually runs both (except the US 1995's)
