Remove any components obstructing access to the leaking gasket or seal (e.g., intake manifold, valve cover).
Carefully scrape away old gasket material with a gasket scraper.
Clean the surface thoroughly with a solvent.
Apply a new gasket or sealant as specified by the manufacturer.
Reinstall components, tightening to specified torque values.
