'91 100q shiftIng difficulty

[Nick Lawrence]

How about the noise from an air leak in the rear main seal,  mine certainly 
worried me for a long time.
See if the noise changes when you press the clutch or maybe pull the 
dip-stick.

I have replaced the master and the slave cylinders in my '91 100q and the 
car
is easier to shift. Thank you.

A less pressing item is related: Sometimes, there's a rotational noise from
the transmission tunnel when the car is at a standstill.. You can barely 
hear
it from outside the car. It's much more noticeable if the motor is running 
and
your sitting inside the car without the car moving.

Something is rubbing while it's rotating. It's sporadic.

Any thoughts!

Thank you.
