I had two leaky places to fix before the problem went away... one was
the leak itself (the muffler to heater box conection)... but the other place
fumes were getting sucked in was the koint between the outer air jacket
and the inner tube of the heater box.

As far as I could infer, the fan pushes air into the heater box, but some how
the air flow produces a small amount of vacumm in that are (the outer jacket
to inner tube joint) that makes fumes get sucked in...

Maybe is was something that just occurs with cheab brazilian heater boxes,
but to be sure, I now got mi german boxes out of the car and welded them
in that joint...

Maybe I should post a picture...
