hi,yeh..glitter in your box aint good,but,if your box is otherwise ok dont worry too much,its prob just bits of syncro floating around after too many savage gear shifts without double declutching.....but the abuse 126's seem to attract makes it important to do the 'box oil,if you do it for the first time in your ownership,do like me,change it,then do it again after a 1000 or so miles,gets rid of all the crap that way.
to refill i find it easier to use this trick,geta funnel,a short lenth of hose,and use a new silcone bathroom sealent nozzel cut to fit the box refill hole,then you can just refill from the engine bay,i use this for doing engine oil as well on the aircooled its a pain to get to the rocker box,and it keeps burping up oil if you try to go too quick.....i just put it straight in at the dip stick hole.
also,oil changes with quality oil is the cheapest way of keeping cars running sweet,make the job easy as above,and do it more often than the books say to,i've got my aircooled running pure green oil now,no dirt in at all
oh, and i use 20/50 duckhams classic for both,hope this helps?
