20V Distributor fix.

["Bob D'Amato" <Bob.Damato@snetel.com>]

Here is the long awaited Distributor fix for the 20V atmo engines. (May 
be same as turbo, but not sure)


SYMPTOMS: Engine makes a strange 'rattle' noise when you blip the 
throttle, heard most predominantly when the rpms fall from +- 2000 rpm 
back down to idle.

DISTRIBUTOR #: 034 905 205J from 90-91 Coupe Quattro and 90-91 90 Quattro 
20V.


1) Mark the general direction the rotor is pointing. Timing is done by 
the computer, so you dont have to be too exact.

2) Remove distributor.

3) Hold shaft by cam gear and move parallel to shaft (end play) this is 
your noise.

4) Drive out Clevis pin holding on cam gear CAREFULLY. Cam gear is 
plastic and breaks easily. (Experience talking here...)

5) Add high quality washer/spacers between the cam gear and the body of 
the distributor, until there is no more play.

6) Put cam gear back on, drive in Clevis pin.

7) Put distributor back in car.

NOTES: I uses very thin stainless washers to get the right spacing. You 
dont want it too tight, the distributer must turn freely.
