mine was running out of slave cylinder into bellhousingandout through drain hole have a look underneath between gbox and rear axle for lots of clutch fluid, you can whip the slave cylinder off very quickly and pull piston out to check seals cheap enough to replace whole unit, but if you want to save a few pounds if you clean the bores and if its free from ridges new seals will do same for master cylinder both need checking as usually old as each other
