3. Repairing the Valve Cover Gasket

Sub-step 1: Remove any engine covers obstructing access to the valve cover.
Sub-step 2: Unscrew the valve cover bolts using a socket wrench, noting their locations.
Sub-step 3: Carefully lift the valve cover off, checking for old gasket material that needs removal.
Sub-step 4: Clean the mating surfaces on both the valve cover and engine with a gasket scraper.
Sub-step 5: Install a new valve cover gasket and reassemble the valve cover, tightening bolts to manufacturer specifications.

4. Check Oil Pan for Damage

Sub-step 1: Inspect the oil pan for cracks or damaged areas; if found, it will require replacement.
