Loud hissing sound when pressing the clutch pedal

Greetings from a returning old-timer of this list. I was an active member of
an old q-list about 10 years ago but uns*bscribed when I had to part with my
beloved 4kq. Now, I have a technical question not exactly about an Audi but
My 1999 Passat 1.8 T, is in many ways similar to an A4 and perhaps some of
the list gurus could help me out.
It first started with a clutch pedal not returning all the way up after
being released. So, I had to push up it with the toe. The brakes beeding was
long overdue anyway, so I bled the brakes and the clutch and the pedal now
goes all the way up. However, there is now some loud hissing or whistling
sound heard when I press on the clutch pedal. I would describe the sound to
be similar to hissing of the worn-out belt. Except it clearly comes from the
rear (not the front) of the engine. So, it cannot be a belt. The sounds
starts to be heard as soon as I press the clutch pedal only slightly and
gets louder when I press it all the way. IIRC, the hissing, although less
loud, was there before the bleeding but now it is totally outrageous.
I suppose these may be a very well known symptom but having very little
experience myself with this type of car, I am asking here for an advise. Any
suggestions would be greatly appreciated.
