I'm not saying that it couldn't be coolent, but if it had a bad head gasket, or a cracked head, it would get Worse when the motor gets hot....

This explanation sounds close to what my friend said when he witnessed the puff of smoke. It just happens once when startin the car, *sometimes*, it seems like, its very slight, and the car doens't smoke at all while it's running.
I do have a nasty smell after accelerating, like rotten eggs, but I think I've got a fried cat which is causing that. I don't know if the fried cat has anything to do with this mysterious "puff" of white smoke that i get.
I love saying puff.
How concerned should I actually be about this, if it is the valve stems?
