[T3] Fan Rubbing

[Stan Schaefer <stans4@ix.netcom.com>]

Here's one I'll throw out to see if it's happened to anyone else.  

When I went to work this morning, I had some noise in the back, I
figured it was bad gas and went easy on the throttle until I could get
someplace to reset the timing.  It was kind of a rattle.  Kept getting
worse, but made it to work.  Made it back home, too.  Odd sort of
noise, not like I'd heard before when I had a mounting  bolt come
loose inside the fan housing. Anyway, I've just finished pulling the
fan and housing apart and found that the main fan(centrifugal part)
had been rubbing on the front part of the housing.  Now the fan bolt
did seem to come out easily, but the only other times I've done it,
the engine was out of the car and I was using a breaker bar, this time
I used an impact wrench with it in the car.  Kind of hard to tell how
tight it was.  The rubbing was on the bottom edge of the inner part of
the "snail".  I would have expected, if the fan bolt was loose, that
it would have been rubbing on the top at the generator side, due to
the belt and all.  Rub mark all the way around the fan, too, none at
the face away from the engine, though.  I managed to clean out the
housing, there was some oily gunk at the bottom, plus alloy dust, of
course. Game called on account of dark, will get back to it tomorrow
night.  I'm thinking that I should probably pull off the front half
and see if it's warped somehow, I have a spare in storage.  Means a
lot of work on cooling tin in the car, my favorite occupation.
Comments and experiences welcomed.
