thanks for the replies folk, yeah i seen that big bolt but couldnt get that out either, there is how ever a smaller allen key bolt above that which is kind of blocked off but has a small 5mm hole, am i ok to fill from this hole?
im having issues with my gearbox just now, i have a y21 lsd box in just now but i have dropped the oil out without checking the fill bolt, which now appears to be siezed and partly rounded off, can i fill the box from any other location?
Have to agree with you there, mine has knackered rings and stem seals, bought it with a knackered gearbox too but still have never had to call the AA in the 30k ive done in it, never missed a beat
