A telescoping inspection mirror, which should be mandatory for any garage, will assist you in diagnosing the VCG leak. Get the mirror and a flashlight, and check along the bottom edge of the exhaust side of the valve cover. But as QAfred said, the fact that you found oil on the metal flange strongly suggests VCG leak.
