I'd let it slide for now . Clean the areas and watch . Check P.C.V. as stated above and replace if needed . Takes about 15 minutes to replace . Longer if stubborn . Use an closed end wrench to get leverage . May want to check the rear corner and the back of of valve cover on the passenger side . That could be a a culprit . Remove any residue in that area . Would also clean any oil from top of the valve cover that may been spilled during oil changes . Do this when checking P.C.V.. I use window cleaner to cut through oil resdue / grime . You'd be amazed how well it works . Paper towels used to remove grime / oil .
