340 intake leak

When i took the car out the first time a couple of days ago .It blew oil on top of the timing cover when i cranked it up, maybe from oil stick.I did not have breathers on valve covers .Did have pcv hooked to back of intake.I have a couple of valve cover breathers coming tomorrow.Should i still run the pcv with both breathers or it does it matter.

As I said earlier, the PCV valve goes in one valve cover, the breather goes in the other one. I suppose 2 breathers in the valve cover opposite the one with the PCV would be okay too, if that's what you want to know.
