There's nothing recognisable as a PCV valve. The whole thing is sealed. The Cam cover vents directly into the main air feed pipe just ahead of the throttle body. The breather which Griffo identified is directly from the crankcase into the inlet manifold, with the spring loaded ball bearing anti backfire valve.

That appears to be it.
