Paul,

Thanks for your help....you were exactly right on all counts...in fact, the
clunking noise had the Audi tech stumped until I told them to check the
exhaust...Bingo...too bad they won't give me a discount for helping them
out.

The vacuum leak and oil leak turned out to be the same thing....broken
breather hose....I don't know how I missed that one.

I am also having my timing belt replaced.  They had the heads off of
another V8 that didn't follow their recommendation to replace his
belt....bent every exhaust valve.  They estimate about $5000 to repair.
Ouch!
