That's pretty normal, it's blow-by that is put back into the intake through the PCV check valve. If you don't want oil in your intake anymore, you can remove your PCV valve and install an oil catch can.

NOTE: If you're worried about emissions, I wouldn't do this.

Actually, in some cases oil in the intake is not normal. I had a Nissan that was doing it and found out that it was not normal for that car. The tube from the crank to the intake is simply a breather to let gases escape and be re-used. Getting too much oil up that tube starts to create a problem with fouling plugs and loss of power. It even started saturating the oil filter, creating another problem.

Oil in the PCV tubing is normal, but make sure in the intake there isn't more than just a little bit of dried oil. If it looks fresh or caked up, clean out your intake tube and throttle body, clean out the PCV tubing and replace the valve.

You're correct in some cases it's not, but in a turbocharged car, you're going to have a hell of a lot more than in an N/A car, so it will most likely not be caked up...

You're fine buddy it's normal

Yup, that's why I said what I said. If the car was N/A, I'd be a lot more worried.
