Zgomot ciudat

Se aude un zgomot metalic intre 1800-2500 rpm.Cel mai tare se aude in sarcina.

Verificat traseul turbo,nu are scapari.
Verificat esapamentul si racordul flexibil.
EGR curatat si blocat.

Turbina e singura care nu am verificat-o.Sincer nici nu stiu cum as putea sa o verific.

Am si o inregistrare.

Problema e ca in cazul lui mi se pare mai accentuat zgomotul si mi se pare ciudat acel tremurat cand opresti motorul si zgomotul care-l face.La fel se manifesta si Vectra Z19DT varului meu, care din spusele mecanicilor, ori trebuie sa schimbe un tampon (n-are legatura cu fasaitul in nici-un caz) ori e ceva in neregula cu evacuarea.

E inceput de fluierat? Mie asa mi se pare. Nu ti-a fluierat pana acum? (in decelerare, accelerare etc)

mergi pe reconditionare , iesi o idee mai ieftin.

Confirm, a mea a facut din al doilea an si m-a tinut inca vreo 2 pana sa o schimb cu alta, preventiv. O mai am si acu pe aia, inca e de folosit. In schimb, nu ti-as recomanda sa faci chestii din astea cu motorul rece, se aude clar zgomotul de metal neuns. Si incearca sa cureti EGR o data la jumatate de an: cu cat e mai infundat, cu atat mai mult aer va trece prin turbina la relanti, marind uzura.

Asa brusc? Vezi ca obturarea EGR-ului duce la cresterea suieratului/fluieratului. Facea si inainte?

Salut.
Referitor la ce zici tu si mie imi fluiera dupa 1500-1700 (ce`i drept a durat ceva timp toata treaba asta si parca mult mai mult fata de ce se aude la tine) dar a si facut POC. Norocul a fost ca nu a ramas turata cum am vazut ca se intampla la alti colegi, ca atunci putea fi mai grav, si am putut sa opresc motorul din cheie. Am reconditionat`o si acum merge brici. Mie mi s`a recomandat unde sa o reconditionez, in Buc, si sunt extrem de multumit. Costul a fost undeva la 800 de ron. Eu zic ca nu se merita sa astepti sa crape ca sa repari mai scump, se pot face si interventii preventive. Daca stiam atunci cum ar trebui sa se auda o turbina normala, sigur nu asteaptam sa bubuie in mers.
Injectoarele le`ai verificat? Parca "tzacane" cam tare, sa nu fie de la asta.. Astea le poti vedea si pe tester, si cu ocazia asta vezi cum merge si electrovalva - sa nu fie o diferenta mare intre ce "cere" si ce "ofera".

intrebarea mea : referitor la modul in care face ca tractorul cand opresti motorul, si mie mi se intampla asta, dar nu tot timpul (ca sa pot sa dau vina pe vre-un tampon la motor) ci .. cand vrea ea in principiu; parca in ultimul timp mai des totusi. Ai idee de la ce e totusi, ai rezolvat cumva? Am auzit si cauza probabila "volanta"..

Masina porneste mai greu pentru ca n-am avut timp sa schimb toate cele 4 bujii.
Referitor la oprire pot fi mai multe cauze volanta,suporti la motor(cel de la cutie e cam uzat la mine).


La furtunasele de vacuum n-am treaba,singura buba o am la electrovalva turbo de langa radiator. Trebuie sa o schimb pe aia.

Am mai facut 2500 km de cand a inceput sa fluiere.....Momentan o las asa,pana crapa.
Singurul dezavantaj momentan e sunetul,fluiera de la 1800 pana la 3000 rpm. Deci ori schimb pana in 2000 ori trec de 3000


I-am facut si niste log-uri cu op-com.

Update : sunetul ala la oprirea motorul e de la ulei in electronica (,) capletei de acceleratie (in caz ca nu e mai grav si clapeta trebuie schimbata..). Eu aveam ulei in electronica, s`a curatat, opreste perfect acum. (thumbs up, again, pt maiandrei care cum a auzit zgomotul si`a dat seama despre ce e vorba)

mie mi se pare ceva ciudat cand opresti motorul nust se opreste naspa ,,, zici ca iti iese de unde e prins e normal sa faca asa cand o opresti ?
