Yes, if it is broken. Visually inspect all vacuum/air intake lines for cracks. If you don't see anything, you will need to do a smoke test. 2004 - 2009 Saab 9-5 PCV Valve Hose Professional Parts Sweden PPS3636114.
At low rpm, when vacuum is high, the valve closes slightly to reduce airflow. At higher rpm, when vacuum is reduced, the valve opens more to increase airflow. The valve also acts as a one-way check valve to prevent forced induction or a backfire. In other words, it won't allow the crankcase to be pressurized.
I had that problem and my engine oil was leaking. I can’t find where the leak was coming from. I found out that plastic valve was broken and oil was leaking from that hose.
WOW! Just cut it so you get to both sides! Like my wife says: the blinding flash of the obvious. Thank you for showing us this!!!
Welcome!
Thank you. Good video.
Welcome!👍
Would a bad pcv valve throw the P1181 code? What brand pcv and part number did you use? Saab OEM and Pro Parts make plastic ones.

Can you make a video on how to do a smoke test on a B235 Saab 9-5? I have a 2009 aero 9-5 Thank you
I hope one day. Thanks.
Where can I get that kind of check valve. I bought a plastic one and I am afraid it gonna break again.
Check part number PPS3636114 online.
Was that a one way check valve?

這零件壞了不更換新品、對引擎有傷害嗎?

If it is broken, you better replace it.
Was this valve a 8mm or 10mm?

為什麼要換這個零件🤔
The one on the car was broken. Replacing a PCV valve, is part of the car's maintenance.
