bummer,hopefully they can reschedule.i blew a hole in the diff casing on my s2 van a few years ago.i drove it for weeks with no oil in it,eventually it fell to bits infront of a few friends when i wheelspun out of a junction,i managed to get enough momentum to coast to a stop further down the road to avoid embarassment but 1 came strolling up with a handful of gears saying 'this fell off your van'!
