Bought a PCV6 kit and noticed similarities with installed stuff in undocumented Saab 9-5 2002 Auto.  I'm wondering if this PM measure was already done. I hope Saabnet posters will chime in to tell me I'm upgrading something that has already been upgraded, saving me some knuckle-busting.

The kit included a foam wrap with nylon ties. Saw evidence of this from the bottom view:

I have no idea if this means the upgrade is done or not. If you can tell from the pictures and let me know, I'd appreciate it.
