    Soup can hose cut.

    Hi. I just noticed that the vaccum hose to the soup can cannister in my '88 CP has been cut at the point where it enters the can. I bought the car recently and I never checked for this earlier. I could'nt feel any suction or blowing at the cut end of the tube with the engine running.What is the purpose of this soup can, and should I get it fixed ? The car runs fine except that the engine misfires occasionally while idling but I put that down to oil on a couple of plugs occasionally. My mechanic told me that was due to the oil rings being worn out on that piston.
    Thanks

    It's a vacuum reservoir. That way wen you go WOT (IE engine not producing any vacuum) all the accessories that work off of vacuum still work.

      Oh, OK. Thanks, but could you enlighten me further ? ( very new to cars, you see). What accessories work off the vaccum reservoir and to what does the other end of that thin hose connect to ?

        When you change the air from vent to floor to defrost, the blend door is actuated by a vacuum solenoid.

          OK, thanks for the clarification.

            Primarily the heater/vent controls. Normally what you'll find with a loss of vacuum is your air conditioner shuts off, and suddenly you have hot air out of the defrost vents with auto climate control. If you don't have auto climate, it just shifts to blowing out of the dash.

            The other end of the soup can hooks to a check valve on the vacuum tree. Directly behind the engine's upper intake manifold, bolted to the firewall is a plastic log with several hose connections. One of these has a short section of hose (about 1 inch), and it goes into a round check valve with 2 smaller outputs. One of the small lines goes into the firewall, the other goes to the soup can.

              OK. This is how it looks at the cut end. I guess I will have to take it in and get it fixed, though I havent experienced any cut off of my AC and I do long trips of about 200 kms in hot weather every few days.

                take a small piece of vacuum line and repair that........your losing fuel economy with that leak......i think you'll need a piece of 7/32" hose

                  From the looks of it, it just seems like its pulled out because it has those ridges on the end. If it is, you can just push it back it then you're good to go.

                    No, it was cut where it joins the flaring which fits on to the nozzle in the can. But I fixed it. I pulled off the bit still attached to the can and a piece of aquarium areation tube fit exactly on to the nozzle at the can end and I pushed the cut end of the vaccum tube into the other end with a bit of Locktite cyanoacrylate glue.

                      I gotcha, good idea on fixing it though. Have you noticed any difference at all after?
