Oil in IC may indicate leaking seals in the turbo as stated.

If you have the stock airbox configuration, the oil tank and crankcase breather are plumbed to the aibox, so oil in the IC also will come from crankcase blowby. All engines will have blowby to some degree. My car had a lot, which is why I am rebuilding the engine. When you pulled the oil filler cap on my car, you could see an exhaust-like puff puff puff of steam...that's crankcase pressure for you.

I always found a nice puddle of oil at the top of the turbo up pipe when I removed the IC...but my car never smoked from the exhaust. I guess Brad Penn burns clean...
