thank you deon to link me the properly discussion and thank you -Seb- about your thread!
Than, as I understood, there is the first screw (ourge boite the vitesse), the second screw (purge differentiel) where there is the pipe attached that "send" oil to differential. To keep the oil stick, the easy way is to take off the front right wheel.
I buy than 4 plt about 75w85 oil, as reccomended from Alfa Romeo, because gearbox+differential need about 3,2l.
Can you explain me what has been reported about the simil-screw that is on differential box? It isn't torx and neither hex...
Grazie anche a te, tonton77 per l'interessamento! Al momento dovrei fare questo lavoro e vorrei avere un parere da chi l'ha già fatto!
