Silver nipple on the bottom of the pic is your PCV valve and a hose should go from it to the intake manifold.
On top the black plastic elbow connected to the white plastic connector should have a hose going from it to your turbo inlet.
Also, the grey plug connected to the white plastic connector should slide onto that 'dovetail' on that black plastic elbow; picture the grey plug being rotated 90° counterclockwise and you'll see what I mean. Unplug the grey plug. Pull the black elbow out of the white connector (it's only held in there by sliding into a rubber o-ring inside the white connector). Slide the grey plug onto that dovetail on the black elbow until it 'clicks' into place. The white connector rotates, so line it up with the grey plug. Then connect the black elbow and white connector together and make sure the grey plug 'clicks' into the white connector.
