Chuck,
Read "The Sermons of Bob Hoover" on Type2.com
site. He explains the reason for your motor leaking is that the synthetic oil, being more homogenus in molecular size, either desolves the wax build up on your seals or slips past them. The seals need about 2-3 oil changes with the synth to rid the engine of the diasour blood and the accociated wax. I don't know if the leaking ever stops, I think it does. Another thing about synthetics is oil pressure will be lower because the oil is going to the bearings not sitting building up pressure.
