you'ld itch your head if you had 2 pcv lines coming off the top. i jb welded the one comin from intake to the valve cover and ran my catchcan hose off the other. i hope i got the right one

 

The line that went from the valve cover to the intake isn't a pcv line, its just a valve cover breather. You put a filter on the valve cover and plug the hole on the intake. The pcv valve on a b18b is entirely on the intake manifold-- the pcv valve itself is on runner two i think almost right below the fuel rail, and it should have a line running from the pcv valve to a nipple on the plenum of the intake manifold. Plug/cover the nipple on the plenum and run a line from the pcv valve to catch can to your intake. This is if you are turbo'd. If not turbo you can just run from the pcv valve to catch can to the plenum nipple.
