[Tigers] PCV investigation

I’m reviewing the Tiger PCV system and the part numbers listed in the Parts
List.

 

These listed part numbers are for the 1963 Ford PCV system, they are not
used on Tiger engines.

C3DE-6A664-A is 3.08” long, made from C3AZ-6A664-A – too short for the Tiger
system

C3TZ-6A666-A – this valve is for the 1963 PCV system, it screws into
C3DZ-6A665-A

C3DZ-6A665-A is an adaptor assembly that bolts to that triangular pad at the
rear of the intake manifold – not a Tiger part

 

The Tiger engines use the 1964 & 1965 Ford PCV systems.

C3AZ-6A664-A is bulk ½” ID hose – 25 foot length – this is the service part
for all PCV hose

 

If anyone has original Tiger PCV parts; I’m interested in the part number on
your PCV valve.

I don’t think there is a part number on the hose but if you see one, I’m
interested.

 

Please include your engine # and group with any reply – pictures welcome.

 

Thank you for your help
