Parts List 6601334            Mk II

6100979                C3AZ-6A664-A                   Hose - PCV

6100669                97331-S                                Clips - Hose

this is the brass part - not correct for PCV valve with hose fitting

6100668                378766-S                              Adaptor - this
is the rubber grommet

 

There are some problems with these Ford part numbers.

C3DE-6A664-A is wrong - this hose is 3 5/64" long according to the Ford
Master Parts Catalog - this is a 1963 PCV system hose

C3AZ-6A664-A is wrong - this is bulk hose - bulk hose would be horrible for
this short distance

 

I don't know the correct Ford part numbers for either hose.

The PCV hose available today is C6AZ-6A664-N with 2 right angle bends.
This hose can be cut for the brass adaptor style hose.   

See pcv hose picture from Ron Fraser

 

Brass adaptor was made by Weatherhead.           See picture from Terry
Packer with Weatherhead Logo

 

Correct brass Adaptor and PCV valves - see picture from David Franchi - also
note that the PCV valve could have AC Spark Plug stamped on it

 

Derek Daily has stated the his early B19KC engine has the brass adaptor
part.  This seems to support that all 260 engines had the brass Adaptor.

 

I have been told that some Mk II engines have the brass adaptor part.   This
should only be possible if Ford stock piled this part for the Tiger engine
build and they changed to the later style PCV valve system only after using
up the brass adaptor parts.   Since the Mk II Parts List is vague about this
and the Mk II Service Manual shows a cleaning procedure for the PCV valve.
I can see how anyone not an original owner could be confused and purchase
the brass adaptor thinking it was correct.

I'm guessing that some of this confusion with the Parts List is due to
Chrysler's involvement with the Rootes Group and the reassignment of
personnel to other programs.   Well, great discussion, I think we all
learned something but I'm sure there are more questions too.

Thanks to all for their input.
