Oil leak on turbo

[JD_975]

Recently noticed an unpleasant burning smell when my surf gets hot, after a bit of delving I think I have traced the source to an oil leak on the turbo, after checking the obvious feed and return pipes I have discovered the leak appears to be coming from the turbo it's self between the two casing halves

Has anyone experienced this and is it repairable or am I looking at needing a new turbo?
