1998 Volvo S70 PCV System Maintenance

I've been researching how to maintain the PCV system and we keep on coming up with information that there isn't a traditional PCV valve in this car. What is it called on this car and what parts do we need to replace or maintain in the system? This is related to an issue with the cam seal and having engine misfire codes. How does the PCV system work on my turbo model.. Where is this all located? How can we replace it? Any help is much appreciated.

It's not just a pcv valve...it's a pcv system.
There is a catch can,hoses,vacuum line,elbows.All of it is located under intake manifold so it must be removed for pcv replacement.How to is in repair database.

I knew it wasn't a traditional valve but I couldn't find where everything was located. Thanks
