200q20v Digest, Vol 39, Issue 33

[Derek Pulvino]

Eric,

Thanks for the update.  I guess I will be going through a similar  
process in the near future.  Interesting to hear you're startup smoke  
problem was at the turbo and not the head.  I have smoke at startup  
about 60%-80% of the time.  I have had smoke while running a couple  
of times, I guess that would be at this point literally a couple of  
times...the most recent occasion having been described in fair detail  
on this list.

Otherwise, even for all my bitching about part replacement, the car  
still runs great and I consistently get comments from people about  
how strong the car runs and what good shape it is...especially for  
one with 240k on the clock.

So, thanks for keeping us updated.

Derek P
