Keith, normally the air out the front seal is when the PCV is used but that oil-filler to CAI tube is removed. Since you have a couple of breathers, you should be ok. If it makes the noise while idling in your garage, you can remove the oil filler cap and see if the noise suddenly goes away. If so, you're on the right track. If the noise persists, it should not be a crankcase ventillation issue.
BTW, it sounds like you did good. You either want a nice closed PCV system (like OEM) or completely ditch that and run breathers. No mixing and matching though, as it can cause a lean condition with unmetered air.
Good luck bud.
