Hi everyone,
I have a problem with my Volvo s60 with 2.4D heart. The problem is that when I accelerate 1.5k and more (especially on cold) there is annoying noise like a whistle. So far I checked all pipes which transmits an air and couldn't find any holes. But the only thing I saw is an oil leak, will attach photos and video with sound. The last one photo is from above the engine with visible oily pipe going to the intercooler. I tightened it as much as I could.

As you can see, an oil leak is in the area between two orange seals. Could it be the reason for this sound?
P.S I don't believe, that turbo is dying. In the summer checked on computer how it's boosting and it was absolutely normal. No smoke at all(with DPF). Car doesn't require extra oil and it doesn't have lags and etc.
