I ordered a new PCV valve and grommet for my 1972 40 with original F155 engine. Is this where the PCV valve is in the first photo? Second photo shows the other end of the 1/2” hose. Thanks for any responses.

Thanks do you know what size hose is attached to yours? I’m not sure if mine is too large? The end of the new valve seems smaller.
Mine is large and thick too. #20 FJ40, FJ45, FJ55, F and 2F Land Cruiser Engine PCV Assembly - 1958-7/80 - Specter Off-Road - https://www.sor.com/cat/030b

Great thanks for the link.
I think the OEM hose was 1/2" at the carb and 3/8" at the PVC.
Hose is more like 7/16 IIRC.
At Cruise Moab 2005, we almost lost @cruiserdan on our run when his PS return hose blew out on the trail. As fate would have it, I was carrying a spare factory PCV hose in my toolbox under the driver's seat of my '68 FJ40. Why was I carrying a spare factory PCV hose? I honestly have no idea. But I was. And it fit perfectly on his power steering.
With a grin on my face, knowing that the hose was already obsolete, and knowing Dan's reputation as a parts shaman, when I gave him the hose, I charged him with finding me a replacement in the Toyota system.
About six months later, a brand new hose showed up at my doorstep.

PCV valve question: My 79 FJ40 was experiencing poor idle. I traced it back to a stuck (open?) PCV valve. Removed, shot some carb cleaner through it. Then compressed air. Reinstalled. Now the rig runs fine.
Before reinstalling it, I shook it and could hear the internal plunger rattling. Do these things have springs in them or does that plunger just float free?

No spring that I know of - gravity pulls the ball back down. It should rattle when clean.
PCVs have a spring…..pretty weak, but in there.
