First of all I'm no expert like your title asks for BUT... I have a breather on each valve cover and a single pcv at the back of the intake and have had no problems with the setup. In fact, my engine does not leak at the intake/head/block joint after most recent rebuild. Like bmalone suggested apply a small amount of permatex sealer to intake (small) to hold in place and across the valley and be super careful lowering the intake into place. I personally like the simplicity of no extra wires/hoses connected throughout my engine - unnecessary ones anyhow.
When you mentioned "spraying" do you mean it actually is squirting out
oil (like under mild pressure)? You might have something else going on. Best wishes!
BTW, I'm sure this isn't your problem since your not currently using a breather on the passenger side but in the past I found that the breather/caps/plugs etc. could be the culprit in
oil leaks due to sealing a pressure.
