Trane heat exchanger

I've got a Trane XR90 Model: TUX1B060A9361AB, Serial: 6482RP37G, Manufacture Date: 11-06. It has a rust spot below the inducer. When the blower is on and I spray some soap on the rust spot it will make a bubble. Is this hole a problem? Can exhaust come out of it? Can I repair it by just gluing some sheet metal on the front? Can the pannel be replaced? Do I need to replace the entire furnace

It is most likley air from the indoor blower blowing out not combustion gas. Have your hvac tech test it with a sniffer to be sure. If it is room air and not combustion gas you can scrape the rust off and patch it with shhet metal and RTV silicone.
But you need to know where the rust is coming from. Is the inducer dripping water down there? Have him check all the condensate drains to make sure they are not plugged and draining1 -
is that picture shown true, or on its side?

I see another problem in this picture. There is a flexible connector or CSST penetrating the furnace cabinet. By code, you can only penetrate the metal cabinet with steel pipe. If the flexible tubing, which is very thin, ever gets knocked and comes in contact with the edge of the metal cabinet, The normal vibration of operating the furnace can result in chafing the plastic cover and the metal tube. If this occurs, a gas leak can develop over time.
There is a condensation leak from the vent or one of the drain tubes that needs to be corrected. Original installer was lazy and dies not understand the code and was taught incorrectly There may be more incorrect items that should be corrected. Have someone that knows how to do this kind of work look at the job and make ALL the issues remediated

After you make that expensive repair and you still have the same problem, What will you check next?

You could put an insulator around the CSST tubing to make it code, couldn't you?0

The picture is true. The furnace is installed on its side.

It seems to me the leak is happening on the other side of the sheet metal that I can't see. The lower black tube is taking condensate from the heat exchanger and directing it into the condensate trap. I don't know how it's collecting the condensate on the other side of the sheet metal but that seems to have failed. What do you guys think of that theory.0

Did you find a solution for it? Mine is exactly the same.
I put a camera during the night and found out the water is coming out of the rust.
