can anyone recommend someone knowledgeable with the G50 box as i have a slight oil weep by the look of it from mine.
not talking main dealer issue here its a 5 speed G50 (long tail version non cable change) out of a 911 carrera S if i remember which i have mounted inverted in a GD T70 lola replica.
i fitted a torsen diff which was easy enough 2 yrs ago but the box seems to have recently started weeping oil mist from the seal/mating face where the actual rear section mates to the diff area. need to know a bit before i start stripping, ie are there o ring seals or gaskets, can they be bought etc? its not breathing oil from the breather system, and never has, this is either a seal leak or case issue with the look of it.
could do with a chat with someone in the know about these boxes if anyone can help or advise please?
many thanks

You'd be better off asking this question on the impactbumpers forum where there is a lot more experience of the G50 box

those manuals are great but they refer to the 915 box, i have downloaded the 993 manual and that shows the 6 speed G50 box, which isnt a mile apart by the look of it. there does indeed appear to be a seal where the gearbox area meets the diff section and it would appear it can be split so i think its a start.
which model 911s was the 5 speed G50 fitted to , is there a guide anywhere? cheers
