hissing, vaccuum maybe

[James Fawcett <jfawcett@mail.win.org>]

Hey all.  I am not sure if this is a real problem but it has been around as
long as I have owned my 86 5ktq, which has only been about 6 months.  There
is a hissing sound coming from somewhere underneath the car.  Seems to be
coming from around the exaust system somewhere, toward the middle/back of
the car.  I don't think it is the exhaust though.  It is a very constant,
consistent hiss, not a beat like the exhaust.  I was thinking this was
maybe some kind of vaccuum leak.  If anyone could shed some light I would
appreciate it.  Thanks.
