Cuplu strangere suruburi injectoare 1.9 dth 150 cp

Buna ziua.
De curand am cumpãrat un astra h 1.9 dth 150 cp. Acum cateva zile am gasit rampa cu injectoare plina cu motorina. Dupa curatare si suflat cu aer, am pornit masina si am încercat sa imi dau seama pe unde pierde.Nu am reusit in prima faza, dar dupa ce am mers cam 100 de km am verificat din nou si am observat ca pe la primu injector ( din stinga) pierdea motorina. Dupa cum arata se pare ca acest injector a fost schimbat ( pare mult mai nou). Ma poate ajuta cineva sa imi spuna cu ce cuplu trebuie strans surubul de la teaca care tine injectorul. Vreau sa il verific, sau dsca este nevoie sa schimb saiba de cupru de pe scaunul injectorului.
Multumesc

Cuplul de strangere se gaseste in niste carti destul de voluminoase si care costa destul de mult. Exceptand service-urile auto, nu cred ca investeste prea multa lume in asa ceva...

Ai putea incerca prin TIS sa vezi daca gasesti ceva...
Eu am folosit TIS doar pentru scheme electrice, dar am vazut la cineva cum se uita pe niste detalii de montaj la diverse componente poate or fi si ceva detalii legate de injectoare si la ce cuplu se strang...

Salut Iulian,in legãtura cu pierderea de motorina pe la injector,aceasta poate fi cauzatã si de oringul de cauciuc de la conducta de retur de motorina.
