That PCV Valve Grommet goes in the valley pan below the intake manifold.
Likely need to pull the intake to install the Grommet.

I actually just replaced mine. 
Smear it with some oil to help it slide through, use a flat head screwdriver to get it through the top of the intake manifold, then maneuver it so it sits even on top of the port for the valley pan, then I used a same size socket with a long extension to hammer/tap it in place. I also used a socket with the extension to tap in the pcv once the grommet was in flush.
Good luck.

Thanks!  It seems like the grommet "sits on top" of the port and the intake keeps pressure on the grommet to hold in place correct?

No. The grommet pops into the port. That's why I said I used a socket of the same size to help hammer/tap it into place once it's been fed through the intake. There will be space between the grommet and the intake. Make sure you smear it with oil so it slides easier and doesn't tear/rip.
Didn't you notice when you took the old one out that it was popped in tight?

Thanks.  My old one was 40 years old and shrunk was just laying in there so I had no frame of reference.

Ok.  I did a horrible thing.  I installed the PCV grommet and it make a nice pop as it went into place in the valley pan.  Then I went to push in the PCV valve (with oil on it) and I pushed the PCV grommet into the valley pan.  :-(   

I have been trying coat hangers, a vacuum with a small hose to try to find this thing.  I have not been successful.

Do you know of any tricks that would help me recover from this.

The grommet was firmly in place and you pushed the entire PCV through the little hole in the grommet and into the inside beneath the valley pan?   Am I understanding that correctly?  If so, how the heck did you manage to do that...it's like impossible. Lol
I'd say you have to pull the grommet back out and then fish out the pcv, maybe with a telescopic magnet.

PCV valve was recovered from valley pan with magnet.  PCV grommet still in bottom of valley pan.  Cannot see it.

Getting the grommet out will not be fun but you'll enjoy a good beer and chuckle when it's done.
You must have smacked the heck out of it. 

Most secure way will be to remove the intake but...

I'd try a flashlight, a scope if you have one, long needle nose pliers...BE GENTLE
It'll have to come out in at least two pieces most likely and ensure you put the pieces together recreating the grommet to ensure it's all there and that nothing is left inside.

This might be a dumb question but what would be the problem in just leaving the grommet in the valley pan if he can’t fish it out?  Can’t get into the engine if it’s in one piece can it?

I got it.  I bought a miniature camera and went in and found it, captured it, drilled a bit into it and pulled it out.  It was a frustrating victory.
