To be honest it was quite an easy job, as i was doing up the last plug i dropped the socket and for the life of me i couldn't see where it landed. i looked everywhere for it but no joy.
So...(I cant stop kicking myself for doing this) i decided to start the car and hopfully the socket will vibrate out.
There was a clunk clunk clang so i turned it off quick. Too late the gearbox oil was bleeding out of every hole.
After many hours of crying, sobbing and pretty much pulling my hair out i've come to the conclusion that im going to have to take the gearbox off to see the damage.
Thats where i found this forum and its been very helpfull indeed. i followed evilally's gearbox removal post. wow where would i be without that. So im pretty much ready to take out the box. just need to jack up engine and box and undo the nuts and mount which i will do tomorrow.
