Re: [AMC-list] 232 Carb Spacer?

[Frank Swygert <farna@xxxxxxx>]

That should be for the PCV valve. You can drill the hole where the nipple was and insert a piece of copper or steel tubing sized for a tight fit. Of course measure the hole and tubing before drilling. A little epoxy or RTV around the tubing if it isn't a really tight fit will help. Size the tubing for the hose then drill the nipple hole to fit -- the hole should be smaller than a piece of appropriate sized steel or copper as the nipple was cast in thicker plastic. The PCV valve regulates vacuum pull, so the slightly larger hole won't effect the engine.

If it has a PCV valve, where it it running now? If it's working fine you could just plug the hole.

Okay, after actually opening the TSM I see that the spacer was actually used for an Air Guard air pump system, used only for CA models in 66. Check for threads in the hole. An anti-backfire valve mounted there, can't tell if it was push on or screwed on for sure, but my money is on screwed on. Unless you need to restore the air pump system for emissions requirements just plug the hole or remove the spacer. The PCV system for that year 232 was just a hose from the valve cover to the air breather with an oiled filter inside the air breather, no actual PCV valve. There is mention of a PCV valve for the 199, but only the breather for the 232 (with or without air pump). Seems a bit strange, thought it would have a PCV, but emission controls were in their infancy in 1966.

So I am working on a 66 Rambler with a 6 cyl and under the 2V carb is about a 1/2 " spacer that has a hose connected to the corner. The one on the car looks like it used to have a nipple on it but it is broken off. Can anyone tell me what it is called, what it does and where I can get one that does not have the nipple broken off?
