Overview
Valve cover leaks are common. Sources include the grommet at the valve cover opening for the PCV system, the valve cover plug at the end of one of cam used for the distributor shaft on non-turbo engines, and the valve cover gasket itself. Most valve cover gaskets lose their elasticity eventually and start to leak. Replacement is fairly straight forward, and a good opportunity to inspect the valve cover for oil deposits which form in many engines by 100k miles.. There are relatively few tools required (T25 and T30 bits, a small ratchet with a bit holder, a new set of gaskets (there is an inner and outer gasket, sold as a kit), and optionally some gasket sealer or gasket "dressing".
