  Jim and listers

  Little more info for those of you following allong,
 Under a heavy foot just starting off in 1st there is
a cloud of smoke out the rear pipe but not under
normal driving,
 looks to be white/grey smoke
 there's all so a lot of oil in the lower intercooler
to turbo hose,
 and in the turbo hose going to the fuel distributor,
 all so oil in the Michelin man hose as well
 I did the compression test as per Bentley
instructions did then twice to make sure they were
done rite.
 I just changed the oil in the car on Sunday and on
Tues I had to add a full quart, the oil wasn't showing
on the dip stick and the car only went 100 miles in
that time.

  Another thing I mentioned the oil loss to my local
Audi Tech whom I have a VERY close relationship with
I've known him for like 10 years so I know he wont
tell me some bullshit story to try and sell me a turbo
or anything but he has said that it's the turbo and he
wont change his mind,
 my question is whats the likely hood that it's the
turbo over the valve seals? on a scale from 1-10.
Thanks for the additional info
