The gases have to pass through a labyrinth in a box, called the oil separator, or oil trap, bolted low on the block above the starter. The top of this has an outlet tube that connects to that three-way flame trap holder. One way out is the small hose to a restricted port of full manifold vacuum. The other way, for when the throttle is open, is through a large hose to the throttle, connected into the airflow sensor-to-throttle hose.

The smallest place is in that manifold nipple where the small hose connects. It is usually clogged solid and sometimes the small hose is too, when the blowby doesn't get sucked up at idle. But the oil separator can get clogged too. If you stick a hose on its outlet port, say a 5/8 or 3/4" ID hose, you can blow through to see if it is clogged. New separators are not that expensive, I think less than US$30, but a job to change.

If you grab the "features" pulldown selection from the brickboard menu, look for 700/900 FAQs. There's a good section in there about the PCV system, kinda unique to Volvo.
