You replaced the engine head and replaced the catalytic converter. Why do you think the air pump for emission control must be plugged?
Do you mean 2 catalytic converters? The car was originally built with only 1 catalytic converter.
Air /Smog Pump Removal
I have an 82 Plymouth Reliant w/ 2.2 engine. I replaced the head and now must plug up the air pump.
Has anyone blocked off the outlets for the pump???
If you have, I would like the instructions on how to do it.
I should mention the following:
I had to get a replacement cat converter last year.Looks like there were two conservers required. Am disabled and unable to get down on the ground to look underneath. But I did drive the car home from the shop that installed a replacement universal cAt converter. I only have one cat.
Need to get this car back on the road soonest. Looking for instructions. Thanks to ALL!!

I think he meant 2 possible converters to choose from, 1 with AIR connection and 1 without.
Some plumbed AIR directly into the exhaust manifold.
Thanks

No, you are mixing apples and oranges. The head replacement has nothing to do with the cat converter. The original converter or converters was plugged. Replaced with one songle converter.You replaced the engine head and replaced the catalytic converter. Why do you think the air pump for emission control must be plugged?

Understand. Why do you think the air pump needs to be plugged? Did the original catalytic converter have an external port which received supplementary air supply from the pump? And now the replacement catalytic converter does NOT have this port?. . . The head replacement has nothing to do with the cat converter. The original converter or converters was plugged. Replaced with one songle converter. . . . .
Why needs to be plugged? Looks like I may not have all the replacement parts. I have no idea about the replacement. I was not allowed into the shop during installation. Here is a photo of the connections for the smog pump. As I am disabled, I cannot crawl on the ground like I used to in order to view what's there. My car is auto trans. Apparently, there are different setups for manual and auto trans cars. Since I have an automatic, all I have is one tube with the check valve. Are there supposed to be two pipes with check valves in the replacement cats?? Inquiring minds needs to know.Understand. Why do you think the air pump needs to be plugged?

The schematic you are showing is a low resolution exploded view drawing of the secondary air injection system. The confusion is caused by the fact that cars built for sale in Canada with 2.2 liter 4 cylinder and MANUAL transmission had a different arrangement of the secondary air injection. On those particular cars with engine - transmission combination, there is 1 air injection pipe that forces air into the exhaust ports at the mating of the exhaust manifold to the head.. . . .

For cars built for sale in the United States and Canada with 2.2 liter 4 cylinder engines and AUTOMATIC transmissions, 2 separate air injection points were used. One on the upstream exhaust system and one downstream at the catalytic converter. So your vehicle should have 2 air injection hose - pipe assemblies. Do you have hose #15 in the schematic? See attached images.
Did repair facility install catalytic converter with no secondary injection port and render downstream air injection piping useless? If you could get someone to lift the vehicle and capture a picture of the catalytic converter and post it, it would certainly help.
OK, I have hose that is # 15 in my photo. I'll do my best to get the car lifted and post the results. Will try and capture a picture as well.
Very helpful images and information Allan!!
Thanks

If it's any help, have hoses #15 AND #18.
I am thinking you are making this observation as you look into the engine compartment from the topside? I believe you do NOT have a problem with the catalytic converter installation.. . . If it's any help, have hoses #15 AND #18. . . .
I think you got misled by the schematic you saw and posted about 2 different images of the air injection arrangement. As I mentioned in post #8 there is 1 catalytic converter for 2.2 liter 4 cylinder engines, 1982 model year. Manual transmission vehicles built for sale in Canada had only 1 air injection point into the exhaust system. All other vehicles use 2 injection points. Final confirmation that you have no issue is to have someone raise the vehicle, inspect the catalytic converter and verify that the downstream air injection plumbing is intact and connected to a port on the passenger side of the converter.
I'll let U know. Going to rain here in next day and it's no fun getting on the wet ground LOL

OK, I managed to crawl under a portion of the car on the drivers side. One tube is toast. The one with the check valve that bolts into the drivers side of the manifold. Will have to get on the ground once again to check what's on the passenger side of the converter. Will let U know. Thanks for your patience. It's not easy doing this at my age.

OK, here's the lowdown. I crawled under the car on the passenger side and I was not able to see anything along the side of the converter. I was not able to see if there was anything in the exhaust manifold ( like a screw in of some sort). SO.....
I have the short hose from the muffler to the pipe on drivers side of the exhaust manifold. There is another hose I bought (4275052). Don't see anything else. Are there two tubes with check valves for my car?? The earlier diagram shows a longer tube. There is a vendor who has one, so I'll have to have a mechanic check further. Looking forward to your reply.
See figure 25-200 here. Items # 17 (short into ex. manifold) and # 19 (long into cat) are the aspirator tubes with the one-way check valves.

Walt: There MIGHT be a plug of some sort on the drivers side of the cat. Looks like it may have been pluuged when new cat was installed. Will have to have mechanic put it up in air to be certain. I have the short pipe w/ the check valve. I just ordered that longer pipe with the check valve. I checked an 87 Omni 2.2 manifold that I forgot I had and there is a fitting where that shorter tube is inserted. That connects to the short curved hose, which connects to a port on the diverter valve. The curved longer hose connects to the check valve on the longer curved pipe and appears to screw into the converter on the drivers side. The mystery will be solved when I receive the longer pipe and get mechanic to put the car on a lift and see what's going on. Thanks Walt for taking time to reply.

I am thinking the catalytic converter was installed incorrectly. If you rotate it 180 degrees this port on the driver side will now be on the passenger side. Then the pipe you referenced goes over top of converter and then angles back into this port.. . . There MIGHT be a plug of some sort on the drivers side of the cat.

When you get this replacement air injection pipe, lift the vehicle and remove this new found plug in the side of the catalytic converter. See if the threaded end of the injection pipe fits. If it does then the solution is to remove the converter, rotate 180 degrees and reinstall. Then you can connect the injection pipe to the converter and the end with the check valve connects to the appropriate air hose from the diverter valve.

I appreciate the insight. It will be next week before I can do more. You will be the first to know what happens. Again, much appreciated. This has been a nightmare!!
I should tell you that I purchased a replacement cat from Rock Auto. When they took the old converter off and laid it next to the replacement. It didn't look even close. I did not see the box the replacement came in or anything about it.I am thinking the catalytic converter was installed incorrectly.
