I've got a foulish question - Where in the devil did they put the PCV valve. I recently got a '90 N/A and '93 N/A Z32s, and, just for common maintenance, I wanted to change the PCV valves in my Zs, but can't seem to locate them. I bought one thinking that its physical appearance would give me a clue. If there is a clue, I don't see it! <LOL>
Your help would be appreciated!

 

This pic shows the location the best: PCV valves and Hoses

 

they're not easy to change with the upper plenum in place.
don't forget that there's one on each side.

 

You're not kidding about not easy to replace! I found the hoses, thanks to the diagram, but can't physically see the PCV valve itself without removing some parts .
Thanks - Guys! At least I know where they are now. I'll figure something out now.
