Volvo started using a ported vacuum fitting instead of a mechanical PCV valve with the advent of the B20.
From the pictures you sent to me last month, the PCV fitting is the one the breather hose from the oil fill cap on the valve cover is connected to.
You should remove the hose and run a soft wire to clear the small hole in the PCV fitting occasionally.
