Hi I hope you bought the three seals as well, radial shaft seal that goes in the slave cylinder, the driveshaft seal for the diff side, you have to take the diff cover off to get at it, then we have the crankshaft seal behind the flywheel and ring gear if thats leaking thats a whole new level, no point in dodging it as it just gets worse and coats the friction plate in engine oil, bit of advice put a bit of plastic over the brake fluid reservoir before !Removed! the lid back on and wrap the end of the pipe in clingfilm when you remove it from the slave cylinder, finally you have to put a bungee on the clutch pedal to stop it falling on the floor, this also stops fluid loss via the master cylinder which iff allowed to travel to the end of the cylinder body will ruin the piston seal so you will need a new one of those as well, I hope you have a four poster to use as the gearbox weighs a ton it took three of us to lift it off of the gearbox jack.
Steve.
