Good story. I'm absolutely certain that it's not inhaling through the exhaust. Dave Stragand's story tells of how he inflated a trash bag on a car that had problems like mine. There's -no- way my car would do that right now. The thing is, how did this happen??? Before I blew the head gaskets, the car was running. Just a few months ago. I haven't backed into a ditch or anything.... Can the guts of the cat "melt"? My fuel system was so hosed up that I got it glowing cherry twice, by accident from raw fuel being dumped in there.
