Questions about PCV

[Compaq888]

I want to change out my PCV valve and at the same time install a PCV catch can but everytime I try I run into problems.

Problem #1, Is the hose from the PCV to intake manifold rubber?? Because whenever I touch it, it's rubber but it's stiff like metal. I thought it has metal underneath it and has rubber as a sleeve. I heard people say that they make the rubber hose stuff so it can handle the pressure there. So is it rubber or is it metal and has a rubber sleeve?

Problem #2, My PCV is not the screw on type. It's the pop on type. Which is the best way to take it out??? I have the breather/separator then PCV then I have that stiff rubber line attached to the PCV by a small clamp and the rubber line connects to the Intake manifold, where it's also held on by a small clamp. So what do I do to take the PCV valve out?? Get the clamp off, rip the PCV out the breather/separator????
