well does it have an aftermarket intake system?, like injen neuspeed, or is it stock? If its stock it might be a faulty PCV valve. If your using the stock filter and oil is leaking in to your intake (or your car is just burning oil, that may be the cause. Im not 100% certain, but **** its always safe to change things once in a while before they do break. If you do have an aftermarket intake and you charged it with the recommended oil and its getting in to your motor i would recommend an AEM dryflow filter. Then driving for some time and see if the smoke is still coming out the exhaust.
Some oil in the intake and turbo intercoolers is normal, usually a few drips with residue inside the tubes. You probably have a problem with either the turbo seals inside the turbo, or the other know engine problems to cause oil out the exhaust, (valve seals and guides, etc etc)
