I'm confused, perhaps someone can point me in the right direction. I have
a '96 850 turbo. I am religious about the service , car has 120k on it. I
don't typically use the dealer ($$$$) but I recently had it in for a
heated seat recall and while in the Tech wanted to service the "flame
trap" and explained it's an often overlooked maintenance issue. It's was
not expensive so I agreed.

Now, just yesterday I read the '96 850 turbo has no flame trap. A normally
aspirated engine does but the turbo does not.

Can anyone shed light on this?

TIA!

IIRC, VolvoUK recommends removing the flame trap entirely.
 
Even though it might not have a flame trap, it still have crankcase
ventilation with oil trap and hoses, and those could also be a good idea to
check, making sure you get the pressure out of the crankcase.
I think maybe the Tech just referred to the whole as "flame trap".

Per
 
The normal situation is as you stated. For turbo equipped cars there is no
filter in the PCV system. For normally aspirated cars there is. However the
small pipe from the filter holder (used as a pipe junction) to the inlet
manifold gets hard and may clog so replacement of this and cleaning the stub
will help to keep everything in order.

Cheers, Peter.
