Before you start paying by the hour to find the leak why don't you clean and degrease the engine. Nothing high pressure, but several easy cleanings should help you find the leak yourself. Once you have the engine clean you can watch for the oil seepage and have a better idea of where it's coming from. Prime example, I was sure my tensioner was leaking as I could watch steady drips from the tensioner while the engine was running. A good cleaning showed me the valve cover seals were leaking something fierce. Changed the valve cover seals, and now the tensioner is bone dry. Hmmm...go figure, somehow changing the valve cover seals fixed the leaking tensioner too
