I have not long acquired a 94 Techno 250, the clutch was acting up and not releasing, So I decided to fit a new clutch pack. When I drained the old oil, it has a very pink colour. I know that water in oil will make it milky, is there a brand of oil out there that acts this way with water or is it a colour of some brand of oil? I guess that if it is water, then the water pump seal would be leaking? Any ideas would be appreciated! thanks
