I would say you have either overfilled your oil or piston rings have unusual wear or the valve stem seals are going. If the turbo has been checked and is new and the supplier said there is nothing wrong with it then i would tend to agree with them.
From the German tuners, Castrol 10W60 racing is recommended. Thinner syntetics like 0WXX are passing the oilseal in your turbo when there is no pressure on the outside (read idling).
The guy's are right most of them do this and it is very embarressing.
I changed the small non return valve near the throttle body as mine was leaking.
I was told this valve's job is to create negatie pressure which helps keep the oil on the lubrication side of the turbo seals.
ie vaccum it only costs a few pence and its worth trying.
its running on vauxhall fully synth.
it only slokes when its hot i.e sitting in traffic, never smokes under load.
the engine doesnt breath heavy at all, and the feed and return to the turbo are new.
i know that it wont hurt it burning a bit of oil now and again but it shouldnt do it. and i also dont want to waste 400 quid getting another turbo if the problem lies somewhere else.
a friend of mine has the same problem, he then swapped from vaux oil to magnatec and it doesnt seem to smoke anymore!
theyre £14 from vauxhall and they are absolute rubbish.
get down to your local pet shop and get a 1 way valve from there for £1
the vauxhall ones knacker up very quickly again (bad design)
ive got pet shop ones on both my calibra turbos and they are just fine

its located ........
if you look at the top of the engine from the front of the car
the top left og the cam cover there are 2 breathers
a small and a large bore
its the small bore pipe that has a 1 way valve
this goes to the throttle body front
I took mine of this weekend and the valve seems to be ok. i.e suck then no blow.
Just to clarify the valve should be letting air towards the inlet away from the can cover.
Still smoke on idol.
I tried restricting the flow of oil from the turbo back to the sump by squeesng the return pipe with my fingers for a second. The smoke got even worse.This to me proves that my fault lies will the turbo as the restricted oil easily passes though the oil seals on the turbo.But am I right? Why cant fault finding be simple?
could be a blocked breather
or a poor oil feed from the oil pump making the turbo run extra hot
i had that problem before
but as soon as i sorted the pipe the smoking stopped.

hmm could you tell me more.Which pipe do you mean?The oil feed?
