In case anyone needs these, this guy has 6 available.

These are the ones that are hard to find.
I just bought a couple. He accepted $6. each, Free shipping. They say AC Rochester on the valve as opposed to AC Delco like Jerry used to stock. They look identical to the AC Delco valves. I have no affiliation.

They do not look like the AC Delco version.

They do not look like the AC Delco version.

The body has identical dimensions. The AC Delco (Right) neck is 0.4 mm longer.
The AC Rochester valve (Left) also seems to be cadmium plated? (the greenish/pinkish finish seen best on the end view) vs. the bright finish on the AC Delco.
Let me know if there is anything else you would like me to check.

Seems correct part numbers are CV913C and CV769C.
Can someone confirm?
eBay link takes me to CV727C.:confused:

Those are the numbers I have (at least for my 1990.)
Looks like the Ebay seller has sold the remaining 6

That's what happened to me. The original auction ended 2 days ago.

I'm not sure they are that hard to find as the AC DELCO 19303069 is $2.66 on Rock Auto.

While we are on the subject of PCV valve. When I had head gasket problem, blowing steam and oil vapor would make the inside of PCV valves sticky. I would spray the inside with fuel injector cleaner, close the end with my thumb and shake it until inside was free and repeat as needed.
Do you think thins type of cleaning could make PCV valves function as intended for a long time?
