Valve cover gasket leak

2003 325i wagon 130k miles



I replaced the valve cover gasket at 96k due to a leak



I recently replaced the PCV system at 127k which I feel was what was throwing a vacuum leak code.



Shortly after changing the PCV system I started to smell burning oil again. Today I noticed the valve cover gasket is leaking again and much worse than before.



Could something have been assembled wrong when I did the PCV refresh that has caused excessive crank case pressure thus making the valve cover gasket leak?
