[Tigers] PCV summary

[Ron Fraser]

Thank you Will

 

Your B19KC engine is from the Oct 1965 build.

This seems to confirm that Ford changed the Tiger engines to the updated PCV system for the Ford 1966 model year.

 

There will always be some confusion here because the Sunbeam documentation does not seem to be keeping up with the engines configuration changes.

 

Well, nothing like a good mystery

Ron,

My IA, 382001570, came with a PCV valve with a hose fitting.  I'm the original owner and I know it came that way.  That style of PCV valve must have been introduced before the MKII and the 289.  I suspect that it appeared at about the same time that the B19KC engine was introduced.  My engine is a numbers-matching B19KC.

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.
