They do not have a spring and check-ball in them, they are open, with
set hole sizes. If you think you are experiencing a flow problem, just
remove it and clean it. It will pull straight out with pliers. Then you
gently hammer it back in to seat it.

Check the sizes of the holes in the PCV. The top hole should be 7/64", and
the bottom two holes should be 5/64". You can check that with the same
size drill bits. IF they're too small, then USE the drill bits to change the size
of the holes. This was an update in the 2010 to early 2013 V6 models.
Late 2013 and up, all have the new PCV orifice sizes. Not sure if the
same year V8s were effected.

I have a 2010 V6, and one bottom hole was clogged, and I had some oil
leaks. I drilled the new holes, the oil leaks went away.

Thank you for your reply.
