Don't worry albert...your english is fine. My French is worse 
. Yes, the foam was used to block area where moisture could condense. The real problem with it was shrinkage and separation over the years. It will allow a leak to soak the foam with water...wherein it rusts next to the metal. If you catch it before it rusts through....I think you will be OK. I think you can remove the foam with acetone. In some areas like the rear of the heater channels, the fender wells and the inside of the back hood, you will at least need to replace it with silicone once you are finished. Ray
