zgomot puternic pornire

Recommended Posts

de cateva zile se aude un zgomot puternic atunci cand pornesc masina dimineata sau dupa ce a stat mult timp pe loc (ca sa descriu zgomotul .. se aude ca un tractor, fara nici un fel de exagerare). o pornesc se accelereaza singura pana in 2000 de ture apoi scade la 1100 sta un timp, apoi scade la 700rpm dupa ce se mai incalzeste putin.zgomotul se aude exact in momentul cand am pornit si se accelereaza in 2000rpm , dureaza maxim 1 secunda apoi se aude normal. este ca si cum motorul nu ar avea ulei . am facut acum o saptamana schimbul de ulei am pus 5w-30 BMW .. si parca de atunci se aude zgomotul. inainte am avut 0w-40 de la Castrol.am pus alt tip de ulei (mai gros) pt ca asa mi-a recomandat mecaniul, se auzea un tocanit ca de tacheti (cred ca inca se mai aude). am pus masina pe tester si toate au iesit ok.

 

vreo idee?
