I know this is an old post, but in case someone else is reading this.
On 2 liter engines, the crankcase is vented directly from the oil filler
cap/housing to the intake tube ahead of the throttle body.
You will see a hose that runs from the oil filler housing to the
intake tube.
At the intake tube, there is a PCV heater valve that incorporates an
oil separator. That has a vacuum hose attached to it.
On 1.8T engines, the PCV plumbing is more involved and incorporates
a couple one-way check valves as well as a "suction Jet pump" to
direct & control PCV fumes to the intake hose ahead of the turbo.
