Vince,
Look under the kitchen sink. Follow the black drain pipe. It will exit the sink, flow through a P trap, and then you will see a round cylinder about 2 inches in diameter. Mine had two vertical slots in it. I taped the slots closed.
If you go to Home Depot or Lowes, look for air admittance valves in the plumbing section. It will show you exactly what you are looking for. I found them on the three sinks. I did not look on the washing machine connection, nor the shower. When you see them in Lowes, it is easy to see how they are supposed to work. They contain a flimsy rubber diaphragm that is supposed to seal when pressure is applied to the underside, but open when vacuum is applied. It is pretty easy to see how that would fail to work over a period of years.
The tape made a big difference.
