Hi there and welcome to the forum,
I guess your oil leak could be from several different places so it would be good to clean thoroughly (maybe with a pray can of engine degreaser) and observe closely to find the source. Sump seal, crankshaft seals, maybe seals at oil cooler or oil filter, or possibly from some seals a bit higher up and making its way down onto and around the sump seal etc.
There was a thread by someone just recently that had a similar oil leak. He thought it wa the sump seal again which he had replaced sometime previously. Oil mmade its way down and was dripping off the transmission. After further inspection he said it turned out to be leaking at the back from a failed head gasket. Hope your's is a simpler problem.
Cheers, Paul
