Wobbling crank pulley + oil pan leak... coincidence?

Recently I started to have oil seep through the front and sides of the oil pan. To double check I cleaned the remnants of exposed oil and ran my engine lightly and short bursts of speed. After 4-5 minutes I looked around the oil pan and there was oil seeping out of the same locations of the pan. I don't believe it's the front seal, but contained around the edges of the oil pan. Before I begin to fix it would a wobbling crank pulley cause vibration to dislocate the oil pan? If so what crank pulley should I upgrade to? Or maybe pressure in the crank case not being vented into the intake manifold? Thanks for any provided info.

The oil pan and gasket were brand new when I installed them. I followed the GM FSM line by line during the install.

What kind of car? year and mileage. When was the oil pan gasket replaced? A wobbly front pulley may produce some balance issues that would produce a front seal leak, among other problems.

The motor is from a camaro SS 2000 with 60k miles. The front pulley is pretty weathered and has rust and the rubber substance is delaminating. Obviously I need a new pulley, but I wouldn't think this would cause the oil pan to leak of all things. The gasket is brand new, it came with the oil pan (2002 GTO front sump).
