best I can tell its leaking fom the case split, after sitting a couple weeks. Does this sound normal for an engine thats never been apart? Is my only solution to completely disassemble engine I replace case gaskets?

 

Double check the oil return tubes. They have a tendency to leak, and are very easily replaced. It is possible that the oil is leaking from the return tubes, and running down to the case split, which is the lowest point under the motor, and giving the apearence of leaking from the case split itself.
