Well, once you've got the flywheel off, make sure it's the seal that's doing the leaking. You could have a crack in the oil gallery behind #3. You probably can't see anything there until you get all the goo off. Also replace the o-ring in the flywheel itself, I've had troubles with that in the past. You can get a proper seal driver for cheap from the local VW parts place, it's nothing more than a big washer that you can use with the gland nut to crank the new seal into place, straight. For getting the old one out, if you've got a slide hammer with a hook, that will work great, otherwise, I muckle onto the seal lip with a pair of visegrips and carefully lever the thing right out. You don't want to scar the mating surfaces or you'll get a another leak. You need to check the fore and aft crank clearance while you're there, this might be one reason you've got a leak. There's shims behind the flywheel and the bearing clearance is best checked with the seal out, really hard adding or changing any shims with it in place. Bentley has the procedure for that. If you don't have the dial indicator it calls for, they sell a jig that you can use that amounts to a bracket that bolts onto the case and has another bolt that you can measure the gap with a feeler gauge when you shuck the crank back and forth. Geting the 启�t loosened is probably the hardest part, you'll need a flywheel lock, a piece of angle iron or bar to bolt across the flyweel and use for a counterbalancing lever, a suitable heavy-duty socket for the gland nut and a heavy breaker bar with a 4' length of pipe for a cheater. If the gland nut has Loctite on it, you may not be able to move it without a torch to heat it up first, heat it til it smokes and then try it. You'll need a new gland nut and washer after that, too. The Loctite turns into a powder and you'll need to chase that out of the threads before attaching the flywheel again.
