Zgomot de patine de lant sau sunt eu paranoic?


Recommended Posts

Salutare,

 

La rece nu se aude nimic. Cand e cald motorul aud un zgomot care mie imi suna a patina uzata.

 

Rog expertii care s-au lovit de problema asta sa-mi dea si mie o parere.

 

E posibil sa fiu si paranoic, dar in general stau foarte bine cu auzul...

 

Motorul este M62 4.4i v8 din 2003 pe x5.

 

Telefonul a inregistrat sunetul destul de bine zic eu dar batea si aer de la vasc in microfon.

 

Aici e filmuletul:

Asa se aude motorul rece:

Clipurile astea sunt egale cu 0. Nu-si poate da nimeni cu parerea asa pentru ca sunetele se aud altfel decat in realitate. Vorbim de microfonul unui telefon.

 

Daca vrei sa faci o constatare cat de cat corecta, mergi la un service si pune-i sa dea jos curelele si vascocuplajul si vezi daca se mai aude vreun zgomot. Astfel scoti din ecuatie un zgomot de fulie, curea sau pompa de apa.
