I noticed oil leaking from turbo charger compressor housing. Pulled fresh air intake hose and noticed oil pooled in the compressor intake. There did not appear to be a lot of oil in the air intake hose. Oil consumption is not high.

Does this mean that the axial bearing bushing is leaking? How long can this go on before it becomes a serious problem? Can it be left alone until oil consumption becomes noticeable?

Any thoughts appreciated - Ron
