Solution

1. Preparation

Gather tools and materials: oil catch pan, rags, socket set, torque wrench, replacement gaskets, and engine oil.
Ensure the engine is cool and parked on a level surface.

2. Addressing Oil Leaks

2.1. Valve Cover Gasket Replacement

Remove engine cover: If applicable, remove any covers obstructing access to the valve cover.
Disconnect electrical connectors: Carefully disconnect any connectors attached to the valve cover.
Unbolt the valve cover: Use a socket set to remove the bolts securing the valve cover. Follow the specific torque sequence found in the service manual to prevent warping.
Replace gasket: Remove the old gasket and clean the mating surfaces. Install the new gasket ensuring proper alignment.
Reinstall valve cover: Bolt the valve cover back in place, following the torque specifications provided by the manufacturer.

3. Oil Filter Inspection/Replacement

Locate oil filter: Identify the oil filter position (usually near the oil pan).
Remove oil filter: Use an oil filter wrench to unscrew the old filter. Prepare an oil catch pan underneath to collect any residual oil.
Install new filter: Apply a thin layer of new oil to the rubber gasket on the new filter and screw it in place until snug, then tighten it according to the manufacturer's instructions.

4. Oil Change (if needed)

Drain old oil: Position the oil catch pan under the oil pan, remove the drain plug with a socket set, and allow the old oil to drain completely.
Replace drain plug: Clean the drain plug and reinstall it, tightening it to the specified torque.
Fill with new oil: Using a funnel, pour the recommended type and amount of new oil into the engine using the oil filler cap.
