Hi everyone,
I have an Mini R60, with 198000km, and an N47 engine 🫥
Soooo…
I think that I have to check the timming chain, and I already scheduled with the mechanic to see this week, but now I have this sound, it’s like an whistle, don’t come when the car starts, only a few moments after, and in regular driving like in highway, don’t ear it, but like in the video, I was stopped and in neutral, I start to rev up and the noise come…
For easing my conscience, what problem could make this noise?

PS: I saw in my garage a spit of oil on the floor, but I don’t see where it comes from.
