Topic: Correct 289 Aircleaner 1967 wo TE SJ ?

[Ralf]

Hello,
Could anyone provide pictures of a correct early 67 aircleaner 289 w/o TE, SJ built?

Did a search here, but couldn't find. The web shows also lots of different aircleaner on 67, so basically no real help.

I think this aircleaner should not have any tube/hose?! (aircleaner > cap)

If this is correct, what would be than the correct breather cap style?

Thank You.

Ralf

The air cleaner I'm finding installed at San Jose on small blocks without Thermactor would be the one where the base only has the opening for the snorkel and not the two other nipples at the front and rear of the base.

To explore deeper though does your Marti report include a comment/option about closed emissions?  And as long as your checking things your DSO might help assure details

The breather would be the flat without nipple painted semi-gloss black. You made no mention if the car was a Sprint so going with what you posted


Couple of examples. Not great unrestored cars but they do offer the details we are focusing on at the moment







Appears to be the original shape of the open emissions breather

Let me add some info to the mix. Here are some San Jose air cleaners bases with a view of the rear. Note the plug.
Another picture of an early, I assume, air cleaner with a tube fitting for the choke pre-heater on the manifold (red arrow). Note the tube on the front. I believe the color for this should be gold. I can't verify VINs, but most of the cars I've had access too were San Jose built.

Mentioned the rear thermactor hook up nipple in the first response.

"not the two other nipples at the front and rear of the base"

Have not seen a 67 small block with the small tube hook up that I can recall.
Were would it attach to. Two years later of different engine had a similar connect but that only lasted a few months before they dropped it.

Would not surprise me if San Jose installed a Thermactor base and plugged the front and rear nipples but it IMHO would be unusual and not something I would do if I didn't have what I considered the original air cleaner

Considering that it has the add on ring (as they did on non- Mustang 390 air cleaners) could that be a non-Mustang application. Believe there is a mention on the second to the last page of one of the 67 Shop tips discussing air cleaners and the additional ring. 

Just my thought given the picture

You said -

I disagree. I believe that all 67 San Jose V8 cars had both fittings, the front used for PCV to the LH valve cover, the rear plugged for non-smg. PVC was a federal requirement for US delivered cars. Smog equipment was also a federal requirement for US cars in 67. I also believe that by August of 66 production (maybe even late July) in San Jose, that a transition was made to the two nipple fitting air cleaners and the rear was plugged for non California, aka non-smog, V-8 cars (Mustang included).
The second picture was identified as early, as in 64 production. Sorry if is was interpreted as a 67 type.

What plug type / material / size would have been used for the rear nipple plug on a non-smog car?

Respectfully you might want to reread your post That or I'm reading it incorrectly

The PVC is connected to the front elbow that would be facing the opposite direction??

When its in use in a closed system its routed to the drivers side breather with no valve as we have discussed in other threads.

Showing it (The PVC) being routed to the carburetor base at the rear not the front of the air cleaner

Don't disagree with the PVC system was a requirement but not sure why you bring that up since it has no connection related or physically is connected to the air cleaner. 

As for all San Jose air cleaners having only bases with both fittings not sure where that statement came from. Would you like to provide what your basing that on?

Looking at Ford and emission testing manuals from the period I don't see the support for your statements as written. Plus having taken and seeing my share of 67 San Jose cars.

Would love to see something that would prove something different

What plug type / material / size was used for the rear plug on a non-Thermactor car?

When it was used - again rarely from my experience - it appears to be the same plug used on the Thermactor pumps when they used a three port in place of a two port pump or the car was a heater delete.  Have some around somewhere but can't put my hand on one this moment.

Jeff,

Marti Report does not say anything about emissions. No mention @ all.

My car was not a Sprint Car.

DSO 75


So finally I understood, the aircleaner for my car has to be in blue colour (inside and out), no niples (neither the elbow nor the straight), including the snorkel and needs to have a breather cap semi gloss black.


Thank you all for the input.

... the front used for PCV to the LH valve cover, the rear plugged for non-smg. PVC was a federal requirement for US delivered cars. Smog equipment was also a federal requirement for US cars in 67.

Just to clarify for terms of reference:
 
PCV:  Positive crankcase ventilation. (Correct term used in context of this discussion).
PVC:  Polyvinyl chloride. (The rigid form of PVC is commonly used in construction for pipe).

Thanks for the clarification about the plug.  Can't say that I've seen that type of Thermactor or rear nipple plug and as you say, it was rarely used.

My Dec 66 SJ has the PCV curved connection in the front, nothing in the back at all.

Don't disagree with the PVC system was a requirement but not sure why you bring that up since it has no connection related or physically is connected to the air cleaner. 

In reality, the PCV system requires air to be drawn into the engine to eventually be drawn into the carburetor. It is called a "closed emission system". That air is drawn from the front tube, bent to the left (thank you for the picture) into the left valve cover fitting (the one used to add oil) crossing over to the right hand side thru ports in the intake manifold (usually plugged with crud) where it gets drawn into the PCV hose into the carburetor. There is a check valve on the right PCV hose (Ford base part number 6A666). Older PCV systems (like 65) used just a breather on the left side. An additional part is that gasses that built up in the engine during a low vacuum time frame are vented into the air cleaner thru that same left hose.

Just to clarify for terms of reference:
 
PCV:  Positive crankcase ventilation. (Correct term used in context of this discussion).
PVC:  Polyvinyl chloride. (The rigid form of PVC is commonly used in construction for pipe).

What plug type / material / size would have been used for the rear nipple plug on a non-smog car?

Rubber. I got another one that had spring type "clamp lines" on it. I don't remember if there was a Ford part number on it.

Would love to see something that would prove something different

Personal experience. When I came (back) to California in 1967 with a 66 "A" code Fastback (Metuchen built, DSO 11) that had an aftermarket HP type air cleaner (it was cool), I had to get a new Ford air cleaner (Tuban Ford, Mountain View), left hand valve cover vent and hose, to pass California emission (smog) requirements in order to register a "foreign" car. That air cleaner had a plugged port on the rear. That's all that was available. After all these years, you remember the DMV and its regulations.
(Note: After the single use of passing a visual DMV inspection, that air cleaner resided in my storage locker being replaced with the HP type. It was put back on the car when I traded it in.)

No worries, often I can relate to the same!

I wonder if this plug would appear in the 67-68 hardware spreadsheet.  An obscure piece apparently not used often, but then again Ford had it stocked somewhere.

[196667Bob]

While it has been mentioned that the breather cap was without the nipple and with a flat top, nothing was mentioned about the markings. My January 31, 1967, Dearborn built non T/E had the block style "FoMoCo" on the flat top (picture attached). Did the SJ non-T/E also have this ? Just to give Ralf the "complete picture" of the cap.

Now that I know what I'm looking for (there is life after "Ford" - before too), the cap part number is C5AZ-9C639-A, is neoprene (possibly), 0.625ID, 0.76L. This is the item supplied with service replacement air cleaners, apparently all that have a port. There are two others listed, one for 65-68 Mustang V-8s, C4AZ-9C639-B, 0.50ID, 0.96L (specific use not defined). Ref: May 75 MPC.

The date codes on the two air cleaner bases I have are 6E (1966 May) and 7A (1967 January).
