PCV hose source
 

Just an FYI, to save others the time it took me to track this down. While MSA, Black Dragon, and all of the local parts houses couldn't get me a new PCV hose, the Nissan dealers (local or Courtesy) still have them (or can get them on order). Of course, it's still like $45 or something, so don't do it unless you really need to. For example, don't take off your intake for a rebuild, leaving the PCV hose attached, and then set it down on the hose. In theory, it could split the hose. Not that I'd do anything like that, of course. :paranoid:
