Oil On Turbine Blade ? ? ?

[TurboR850]

Looking at this turbocharger, you can clearly see oil on the turbine blade (looks like oil, what else could it be ?) It only has 4000 miles, and has a Super 60 Compressor wheel, thats the only modification. Why is there oil on the turbine blade ? ? ? A Seal Broke ? ? ? When the turbo was taken off, oil got on the blade ? ? ?

Oil seal leakage at turbine end of the turbocharger

CAUSE: Excessive pre-oiling.
SOLUTION: Oil will burn away no action required.

CAUSE: Plugged engine crankcase breather.
SOLUTION: Refer to engine manufacturers service manual.

CAUSE: Restricted turbocharger oil drain lines.
SOLUTION: Clean and remove restriction or replace oil drain line as required.

CAUSE: Sludged or coked center housing.
SOLUTION: Service engine lubrication system. Replace Turbocharger.

CAUSE: Turbocharger bearings, bearing bores or shaft journals worn.
SOLUTION: Replace Turbocharger.

CAUSE: Engine malfunction (excessive piston blow-by or high internal crankcase pressure).
SOLUTION: Refer to engine manufacturers service manual.

CAUSE: Over-full crankcase.
SOLUTION: Adjust oil level in crankcase to proper level.

my t25 gets oil in it all the time becasue of the valve cover recirculates air into the intake. i need to change that, about time to get a catch can & cap my pcv.

aah, the "moron solution", that's not recommended.

If oil gets into the combustion chamber or into the exhaust at the turbocharger the only thing that will be left of it is blue smoke and carbon build up.

If oil are getting by the piston ring seal at the turbine side of the shaft it will be noted by blue smoke, usually at low load.
