[s-cars] white smoke

[michael musmanno]

my '93 s4 has a white smoke problem.  is it new turbo time?  when the 
car has been sitting most of the day, I start it up and some white smoke 
comes out the exhaust.  it's a decent size puff, then thats it.  as I 
follow behind my wife driving the critter, when she's driving it, no 
constant smoke, just each time she shifts.  and as she drives the smoke 
gets less and less, until there is no more smoking.  is the turbo going, 
or is it something else.  any thoughts/suggestions are greatly appreciated.

thanks
mike
