Follow up and let us know if you fixed it, too. The baffles underneath the valve cover are often overlooked (not transferred) if the valve cover is replaced but they're crucial to letting blow-by gasses out and not oil. I have yet to see an aftermarket valve cover with baffles already installed.

We REALLY need to know what year first.
