PCV system maintenance interval?

What is the maintenance interval for a 1963 V8 crankcase ventilation oil separator?
See: Oil Breather Screen-Mesh Filter #C2OZ-6A631-A for 62 63 64 65 Ford Mercury 221 260 289.

I had been under the impression that my PCV valve #C1AE-6A666-F was supposed to be changed every 30,000 miles.

I read in my recently-purchased book "Small Block V8 1962-1969" by Bob Mannel that Ford had recommended that the PCV valves were to be disassembled and cleaned every 6,000 miles.

Oops. My PCV valve has been in there for over 16,000 miles with no maintenance. :(
I will take it apart and spray it with carburetor cleaner this morning. :)

If the check-valve in it still rattles when shaken, it's good. I don't think I ever heard of anyone replacing one that worked, unless for cosmetic reasons. The breather screen can be cleaned if unsightly. It's so coarse I think it'd be almost impossible to plug up.

Yeah - what Gene said.

Never seen that book before. Will have to look it up. What sort of topics does it cover?

Gene was correct. :)

"What is the maintenance interval for a 1964 ½ V8 crankcase ventilation oil separator?" I found the answer to my original question in a 1965 technical bulletin that is included on Page J-56 of Mannel's book:

Ford said that the oil separator element was to be cleaned every time the PVC valve was serviced and that: "Failure to do so will greatly reduce the operating efficiency and service life of the engine."

Wow! I had never cleaned it. That worried me. So last night I removed the PCV tube from the rear of the intake manifold to change the oil separator. The existing oil separator element did not look that bad after all, ......

....... but while I was into it I replaced the old element with a with a new old stock replacement part that I had.

I scraped the old petrified paper gasket off with a razor blade and then smeared the new gasket on both sides with motor oil before installing it. I think that the little basket that the oil separator sits in is pretty cool:

The existing PCV valve rattled when I shook it, so it seemed OK. I sprayed carburetor cleaner into both ends of the PCV valve and into the curved metal PVC tube and then reinstalled the PCV valve.

I drove my car to work this morning with an optimized PCV system!

It is a good book. It is broken into chapters for each year, 1962 to 1969, and is broken into sub chapters of engine core, valve train, induction, exhaust, lubrication, ventilation (PCV calves), cooling, iginition (distributors), generator/alternator, and accessories. Everything is shown wqith photographs of actual parts.

The book showed me where the date code for my engine block is located and how to read it. My block was cast on January 2, 1963 (it was a Wednesday). The first number is the year, the letter indicates the month H = 8, the 2nd number is the day, and the last letter is an inspector code.

My 1963 intake manifold C3OE-9425-C that was purchased off e-bay was made on August 23, 1962 (it was a Wednesday).

My car was built by members of Lorain Local United Auto Workers 425 on Monday, July 22, 1963, at the Lorain, Ohio assembly plant.

Attachment 6032

The stars were all against my Falcon. The engine was cast by workers coming back from celebrating the New Year, and my car was made on a Monday! :)

Most mistakes can be fixed.

Thanks for the heads up on the book. Gonna keep my eyes open for a copy. You can never have enough references. Though the Internet is making this less an issue, I still find information in books you can't (easily) get on-line.
