Do you mean the air intake hose at the turbo? There will be only a little bit of oil in that section, if any. Most of the oil consumption by the turbo is due to the output oil seal weeping a bit and causing oil vapors to collect at the bottom of the intercooler.

The intake air hose has a PTC nipple (with electrical connection) that changes flow of crankcase pressure when the turbo is at boost. This nipple can and should be cleaned every 100K or so. It gets carbonned up badly and the PTC can no longer close. A pain to clean as it means the removal of the intake pipe just to be able to see it. I used a very small screw driver and carb cleaner.

Also check the vacuum hoses in that location, they should be clamped.
