Bob Mannel's book, PDF Edition
<https://fordsmallblock.com/product/pdf-edition/> - Home of the Ford Small
Block V8, indicates there are 4 possible PCV valves for the 1964 system.
C3TE-6A666-B, C4AE-6A666-A, C4ZE-6A666-A1 and C4ZE-6A666-A2 and 3 for the
1965 system - C5AE-6A666-A, C5AE-6A666-B and C5AE-6A666-C

             

All original Tiger PCV valves are serviceable; meaning they can be taken
apart, cleaned then reinstalled.

 

I still see some gaps in these part numbers that can only be filled in by
Tiger Owners.   If you have or think you have Original Tiger PCV system
parts I would like to know those numbers.   Please indicate your engine
number and group with any reply.   All additions and corrections welcome.
