90Q Brake Vacuum Assist Unit ( TAP TAP TAP NOISE)

[J Kurt Bonk <KaBonk@mindspring.com>]

I had a loud tap from the top of the engine(thought valves)...local audi
guy said it was worn lifters........... I was informed by a lister that
the Brake Vacuum Assist Unit, on the drivers side of the engine
sometimes made that noise.  I cleaned the unit but still had a tap in
cold weather.  Using my polish mind I turned out the retainer bolt to
the spring 1.5 turns, to apply more pressure on the plunger, which rides
on the camshaft............so far NO noise........Did I find something
???????
