Oil blow-by on Turbo
I just had an issue with oil/coolant mix.. The wrench that works on my car says that the white smoke that I am getting is oil from the turbo. The coolant appears to be maintaining proper level, but on boost I get some white smoke.
So what risk do I run driving the car and pushing oil past the intake? The car has 16 psi and drive good.
The wrench said $4.5 parts and labor for a new turbo, wow!!
It is a K27DR from Powerhaus, the real question is how long should I go before I get it rebuilt?

Ok, what does $4.5 mean?
My 951 does the same thing, boost makes smoke, the amount varies depending on oil type, temperature, gear I am boosting in (oddly), and other conditions.
It doesnt seem to smoke when I short-shift, and it barely smokes in 5th with WOT. In 2nd, if I run WOT, I can get a pretty good plume. Mostly I worry about my catalytic converter.
I am planning a valve seal/turbo seals and bearings replacement this summer. And likely an exhaust upgrade, since I can tell it is constricted at high RPM's.
Just waiting on my back to heal so I can go worky-worky some more. (hehe, me sucky-sucky long time for stand alone engine management)
(j/k, in case you had one laying around) (unless its a sweet *** Motec) (haha) 
I would do it right if I were you, with the understanding that sometimes reality sets in and you cant spend all you would like at once.
You can purchase Turbo rebuild kits from several vendors, which are much cheaper than new turbos. That way you can also afford the new valve seals and maybe some new gaskets up top. Better to have a car that runs right than slap more power onto a suspicious engine.
I assure you, when they run right, you can get a ticket in any state. And you will be surprised how fast it will be when you arent "afraid" of a giant embarrasing smoke cloud. WOT at full boost is very addictive.

That dealer is full of BS! It only takes about 6-8 hours to install a turbo. You'll need about $50 in compression-gasket seals, O-rings and new nuts & bolts. The turbo rebuild-kit is about $200.
While you're in there, you might as well upgrade to a higher-flowing turbo. SFR and TEC in Colorado have good deals on Garrett turbos. Watch out for the K27DR from Powerhaus because the compressor-wheel nut is not left-hand threaded. Several people have had it come loose and grenade their engine.
