Hmm, well, here's some shots in the dark.

Might be related to below, might not.  Oil level is half way between 
min+max, yes?

Hmm, that doesn't sound encouraging, but I wonder why you only get it 
when the engine is cold.  Maybe have someone else start the car up 
while you listen(with hood up)?

You can of course check the turbo.  Should be very little play in any 
direction(like, next to none) on the turbo shaft, and should spin 
somewhat freely.  Also check the hose coming off the turbo for oil.

Is it smooth, or stumbling?  Does it pull strongly+quickly to 1.4/1.5 
bar?  How's the mileage?  Any codes?

Yes, it's a horrible design.  If you want, remove the trim pieces etc 
and pull the IC and replace that o-ring, but I'm guessing its not the 
problem.  A check for oil around that joint usually turns up quite a 
bit of oil/dirt, but not much of a leak.

Might want to do a step-by-step trace of the entire intake system 
checking clamps and such.  I left a clamp very loose on the 
pipe->throttle hose, that wasn't fun...

Some other wild a$$ guesses:

-leaky injectors(maybe try a bottle of techron full strength stuff?)
-busted fuel pressure regulator(long shot, but they have been known 
to go bad on the V8, for example, leaking fuel into the IM through 
the vacuum line; should be very easy to check, just pull off the 
control line and see if it leaks)

In the meantime, drive the car -very- gently.  Sarge lost his 200q20v 
in a very similar way(suddenly started belching smoke on startup), 
although it was chipped...
