Ah yes. Someone has blocked it off.... It looks like some point In the past the PCV valve has been removed, possibly due to it breaking (common fault). I'm not sure of it has had some of the pipe where the bolt is snipped off as it should bend towards to where it would plug into the PCV. There's a thread on here with information on the PCV valve. Let me dig it out Edit: here is the thread that will provide more info http://www.vr6oc.com/e107_plugins/forum/forum_viewtopic.php?232789
