Oh man that sucks. I can't quite identify where the leak is on the engine. If it is from the case parting line there is no gasket there. Only a sealant is used on the case parting line.
Uwon a member here had a similar problem and if my eyes are right it appears to be from the same spot, though yours appears worse. Here is a thread he did in the subject.

If I can do anything to help out let me know.
