I have information in my factory service manual but can find how to post photo in my reply.

Getting back to the off subject part...  This is a NOS LH controller showing the three vacuum ports for temperature at the top, (behind four speed fan switch) and four vacuum ports at the bottom for changing air flow.

What was the third valve in the heater pipe for?

I think only ports 1 and 3 are used. Port 2 must be a vent or not used at all. Port 1 is vacuum source. Port 3 is water switch.

Brad your air cleaner is definitely off a factory A/C car . I can take pictures if mine but what are you looking at , is it the angle of the snout ? I never noticed a different angle but I’ll check it out you could be right . There was a slight difference between LH and LX , the LH has an extra vacuum port underneath for the auto choke . On LX it was deleted and moved to the carby

[hanra]

Correct. The well known Facebook Expert stated my intake snout was on the wrong angle. My assumption was it faced slightly further forward to accomodate the A/C equipment on the firewall??

Funny how he used to always message me asking for advice or help just to build a replica of my car.

I don't have a standard air cleaner to compare but he may be right , if the snorkel came out at 90 degrees it would hit the evap box and VIR pipes . The last picture with the red circle is where the LH had an extra pipe

The well known Facebook Torana Expert has said that my air filter is incorrect as the intake snout is not facing out at 90 degrees. That’s all he is basing it on.

I’ve said to him it’s to suit a V8 Torana with A/C and as I assumed, the snout cannot sit at 90 degrees as it would hit the A/C box on the firewall, which your pics clearly show.

He was private messaging me and wouldn’t accept what he was being told. Once I had enough, I called him “an expert”. And thus he has blocked me on Facebook.

Yes, that circled pipe is the one that connects to the auto choke pipe that runs through the exhaust manifold.

I don’t think my snout points as forward as yours. I’ll take another look.

[hanra]

You can see in his diagram his expectation is for the snout to sit outwards at 90 degrees.

Just tell him to go back to school.

[hanra]

I wish I could. He has blocked me on Facebook which is disappointing as I used to enjoy see his expert commentary on all things Torana.

As you can see the snout angles slightly forward. Which makes sense so it can clear all that A/C gear on the firewall. It looks pretty busy there!!!!

Sonds like a tool, but its Facebook so can't assume much in the way of IQ.

[tuxedoss]

Yours is definitely the same as mine . So does a non AC one sit at 90 degrees as I’ve never taken any notice. Yes it sure is busy , it’s not a great setup , you can imagine the hassle to change the rocker cover gasket or the number 8 spark plug. But trying to keep it all original. The challenge is to get it working without being able to use R12 gas

[hanra]

That would be a nightmare! But awesome to be able to drive around in cool comfort instead of sweating ya ass off..... 

 

Yes, I believe a non-A/C air filter base has the snout at 90 deg to the front of the car and facing the inner guard square. 

 

I feel like mine angles back towards the firewall a little more than yours. It looks like my oil cap is more visible in that overheard pic? 

 

Will the system not work with the new modern gas used these days? 

[yel327]

If you were wanting to do it Brad you wouldn't do it as per original. You'd leave the heater box as it is and just not have it connected. Remove the heater unit and ducts inside the car, and replace it with a Vintage Air unit, either the GenII or the Compac. Make up a way to support the original vents where they belong and brackets to support the aircon unit where the existing heater/fan and run ducts under the dash to reach those and the other factory locations including the demister. You could use an original Harrison compressor mounted as per original or fit a Sanden style unit. Find an original condenser or fit an aftermarket. You'd just have to cut under the original plastic box on the firewall to route the heater hoses and aircon pipes through it, or delete the box and make up a plate to bolt where it goes and use a 4-way bulkhead fitting. Keep your existing lower dash fascia and find an old one to clean up, paint and cut out the right size for the Vintage Air controller which would mount exactly where the existing dash controls are. See attached link, the installation instructions are in a pdf link inside the link, shows you the dimensions. This fits perfectly in a HK-HG dash where the heater/demist controls go without cutting, not sure about the hole size in LH-LX as my last body of one of those is long gone. Just needs the plastic trimmed neatly around the hole.

Here is the details of the Compac, it is only 10" wide, 7.5" deep and 5" tall. Should easily fit where the original heater box was.

So just to put this subject to bed.

P/N: 9937648 air filter is to suit ADR27a LX Torana with Air Conditioning.

So yours doesn’t have that extra vacuum pipe on it if it’s an LX one ? Up to you but you probably should look to get a non aircon one and move that one on with a profit as almost impossible to find one

[hanra]

I went and took a look and I can recall actually drilling a hole and fitting a port there for the auto choke pipe.

I’ve butchered this one now. It’s got the front PCV port blanked with a grommet. And I’ve cut a hole at the rear and transferred the PCV port to the rear.

Worthless now.

Thats tidy. 

 

Shame about the front number plate bracket... The correct ones are available all over FB..

And did you see his air cleaner and rocker cover

[hanra]

Ah ha. I do now! hahahahaha

[tuxedoss]

Just incase anyone's interested in resurrecting the old factory air I seem to have managed to do it even though I continually read it will only work with R12. I decided to try the Hychill Minus30 as no license needed to buy it as its pretty much just BBQ gas in a can. I rebuilt the VIR with all new O rings , replaced all the hoses and flushed everything internally except the compressor. I have a rebuild kit for it but as it was reconditioned  30 years ago and not used much  I figured I'd leave it and try my luck, if it leaks then rebuild it. I also bought a vacuum pump and evacuated the system for a day and it held vacuum so figured so far things were going ok. Put in 350 Grams of gas , they say 340 but went a bit over , fired it up and it went instantly cold, low side sat at 30Psi and high was only 160Psi, it was only just over a 20degree day so not a real big test but I got a constant 2 degrees out of the vents. Time will tell though.

Did you add some lubricating oil for the compressor?

[tuxedoss]

Did you add some lubricating oil for the compressor?

Yes drained compressor of all oil and refilled with the hychill synthetic oil , it takes around 10oz or 280ml
