I don't believe that any 850 volvo turbo has a flame guard/pcv valve. There is positive pressure in the air intake when under boost from the turbo. The flame guard on a non-turbo is just prior to the throttle body, in the air supply hose.

The gases from the crankcase in a turbo are drawn in just prior to the turbo where there is always vacuum and never positive pressure.
