Hi there. Check the positive crankcase ventilation valve (PCV) and see if it’s plugged up. Also, check the engine oil and make sure that there is the proper amount of oil in the engine. Too much oil or a sticking PCV valve will cause the engine to build up too much crankcase pressure and blow out the valve cover seals. If you need further assistance with your leaks, then seek out a professional, such as one from Your Mechanic, to help you.
