PCV valve? S70

You wont find one in your car, it doesn't exist. What you do have is an oil separator box, and if you use non-synthetic oils and never run the engine hard and hot, sludge will build up and plug up the box and the breather lines.

Make it good practice to use synthetic oils, change the filter frequently (5K miles). I try to change the filter at 5K intervals and drain the oil at 10K miles, give or take 1K miles. I also drive above 2K rpm once the engine warms up and I am not stuck in stop and go traffic.

It is almost time for you to replace the gas line filter. It is cheap and easy to do.
