Ok, after my post apparently got stock in the middle of nowhere and 5 beers (0.5 litres) and seeing the soccer team I support losing again 3:0 I think I am ready for a second try. Let me recall where I left it:

Oh yes, the gearbox. So the car was registered and technically also driving around but I couldnt do much with it since both the gearbox and the differential made a heck of a noise when driving (adding to the temperature problems mentioned previously). I attach a small sound check (not the nicest video quality but you get a glimpse of the sounds I was getting when driving).

So after spending a little time in some german cosworth community whatsapp groups (SHOUTOUT to all the guys! The Cossie crowd in Germany certainly is not as large as in the UK but there are quite some fine and helping chaps out here too!), I found someone that was supposedly able to overhaul my differential and had an exchange gearbox for me (I had to let go off my broken one and some extra cash thought). But before I was able to have the parts disassembled (?) / removed from the Sierra I had to pump up 4 flat tires (suppsed to be new) after leaving the car for 6 weeks in the garage. *sigh*

ANYWAYS - this is what the status was (old unit out, new unit picked up in the trunk of the Kuga):









P.S.: I mentioned it before but in case anybody is looking for some airbox clips for the Sapphire 2WD - check this page out: https://www.csp-shop.de/motor/klamme...11-26809a.html
