2007 328xi oil leaking from intake manifold

[jstancoautobody]

I just troubleshot an oil leak coming from the intake manifold. New gaskets stopped leak, should I go after the oil in the manifold issue? Oil was very clean, which makes sense because I recently did an oil change. The leak was prior to the change. Could this be blow-bye, even though oil is clean? This is a non-turbo 3.0.
