Hello!

So I have yet another problem with my 270CDi. Was driving on freeway and then something started to whistle. Stopped, checked under the hood, everything was ok. Then it got worse - engine makes sound like there is massive air sucking problem. Went home unhappy. When accelerating over 1.7K RPM's the engine itself makes sound, like there is something wrong with one of the cilynders. I'll add video for you to better understand the problem.
