@@saabmastertech5852 In my experience not always, but often. The PCV valve is a rubber flap in that plastic tube thingy, and it simply dissolves over time. I think on most 9-3's of this vintage they will be competely gone. Thing is: they are hard to change and also testing them is not too easy, the TB needs to come off. Most mechanics do not bother to check them in regular maintenance. A broken PCV causes oil to be everywhere over time, and pressurizing the cranckcase will eventually fail the cranckseal, and the oil the pressure sensor as well. The head-related ones (valve seal, vacuum pump, power steering) are less clear, but very well possible.
Without people like him we would be lost with our cars. Thank you for helping us running our cars and maintainig them!

I hope you might share a video on replacing the heater on a 1997 9000 CS or could say how difficult it is to do! 😄😄🌻
Great suggestion!
And the reason of all these leaks is broken PCV valve in the intake manifold.
Did you mean every time there are leaks, is because of broken PCV valve?
