2008 Turbo Air Hose Lubrication

Hi everyone, I'm driving a 2008 with a 1.2 liter gasoline engine with 130 hp. There's oil leaking from the turbo air hose connection on the left side of the engine. Has anyone experienced this before? What do you think could be the cause? I'm not someone who drives very hard. All the gaskets were replaced at the dealership, and the problem persists. I think it could be a faulty PCV valve, but I'm not sure.

Hello, I have the same car with a 100 hp manual. I had the same problem. Were you able to solve it? A few mechanics say it's normal, don't be afraid, don't sweat, they just dropped 1-2 drops and it's fine. But I'm not satisfied. If you solved it, could you write it down?
