Smoking at the stoplights -- 95 a6q 5 speed

[TooManyAudis at aol.com]

I've been going through some oil lately, so I had a friend drive my 95A6q 5  
speed with 220k miles as I followed behind in his car so that I could see 
what's  coming out of my car's tailpipe.

Normal driving down the road -- no  smoke.

Approaching stoplight -- light smoke.

at stoplight -- light  smoke

pull away from stoplight -- heavy smoke for 3 to 4 seconds, then no  smoke as 
the car gets up to speed.

My first suspect are the valve stem  seals. Although I replaced them 15,000 
miles ago when I did the timing belt. I  suppose one or two of these buggers 
could have worked their way loose, or just  become worn (although 15k miles is a 
very short time to see a  failure).

However, I want to examine all possibilities before tearing  into the engine 
again. 

Are their any other items that could cause  similar symptons, i.e., pulling 
oil into the cylinders while engine is under  vacuum?

Thanks,

Tom
