Oil leak near PCV valve.

Any thoughts where this oil leak is coming from? Highest point on top of the engine passenger side. I replaced the PCV valve and hose assembly. There is an oil galley plug near by that doesn’t have a washer or gasket if normal. I thought it could be the breather hose underneath throttle body but no UV dye from the oil around it. I’m guessing I don’t have the vertical PCV hose to engine seated and tightened correctly. Anything else from this area that can cause oil to pool up on top of the engine?
