I have an 1984 Audi 4000 and I recently installed new pistons and rings. Everything went smooth, but I new I can't get the oil pan to stop leaking oil. I've replace the gasket 3 times, torqued the nuts to spec,, used high temp gasket sealer,, and still get a leaky gasket. The gasket is the cork kind. What am I doing wrong?
A build up of pressure in the crankcase could force oil out of various places due to the high pressure, if the new pistons / rings are not a good fit, gasses will pass them & cause a massive increase in pressure in the crankcase, remove the oil filler cap & run the engine, there should be virtually no fumes / pressure coming out of it, put your hand over the filler cap hole & gently rev the engine, if you feel the gas pressure against your fingers you may have a serious problem, either ill fitting pistons rings, or a blocked crankcase breather,

Is that cork gasket splitting? You are torqueing it down too much. You will have to just get bolts snug with that cork gasket. The dealer, and some aftermarket places, can sell you a very hard gasket that when you torque it down it will not require sealers nor will it leak.
Or there is a straight RTV option but you definitely only tighten the bolts a little to get an even seal all the way around the surfaces.
ALWAYS MAKE SURE THE SURFACES ARE GREASE/OIL FREE!! And that is no small task with the engine block. lol

Art, In addition to what Dave mentioned, note that if you are using Synthetic oil, you may experience leakage through the gasket, as the synth has a way of shrinking cork gaskets. Cheers!
Another thing to check is if you have stretched the metal around the bolt hos by tightening too much. If you lay the pan on a flat surface it should seal and not stand up on the stretched metal by the bolt holes.
If they are stretched, you can carefully bend them flat with the rest of the surface by carefully hammering them back to flat.

Also check if the surfaces of the pan and block are clean and almost like pollished. The head of the engine in my car was revised by a specialist and he made the head faces a bit rough at the top, so the valvecover gasket was leaking everytime. Took some metal pollish and pollished it. Now it almost does not leak (since >50.000km).
