Hi 12j
If it can be shown that EP oii has damaged the plain bearings it will be the first positive evidence revealed here as far as I can determine. Most oil companies claim the oil will not harm bronze, or not at the temps likely in a Seven, although they do not make clear if this includes wearing surfaces. From my limited experience I have seen no wear failure of bevel geras. But if the comstant meshed front gear is totally failed the oil would appear like silver paint.
During the 1950s thru 70s EP oil found its way into very many gearboxes without apparent harm.
