Oil in the IC hose?

There are two possible sources of oil in the intake system.
Worn turbo bearings causing oil leakage into the compressor. Very bad, but
A light oil coating in the intake system is usually from the crankcase
breather system which, under boost, exhausts into the intake system just
ahead of the turbo air intake. Hard right turns with a full crankcase
aggervates the problem. There is a flakey oil seperator in the breather
line, Bentley shows it located near the exit from the crankcase, but it is
actually the ell fitting located high on the passenger side of the engine
just as this breather tube turns forward and behind the heat shield toward
More of this oil aerosol exhausting the crankcase can be condensed and
returned to the crankcase by adding a stainless steel kitchen scouring pad
loosely stuffed into the enlarged section of this hose immediately above its
connection with the block.
