I did my service today and thought i'd check the turbo area and I found some oil on the hoses coming from the air intake what should I do next?

Ok i've done the suck test while the actuator is still fitted and its not holding a vacuum you can just keep sucking so I should presume its a failed actuator should i still worry about the oil? I cant see any oil on the undertray so I dont think its too bad.
