Tools required: socket set, torque wrench, oil filter wrench, rags, and UV dye (if applicable).
Ensure the vehicle is on a flat surface and secured with wheel chocks.
Safety warning: Allow the engine to cool before starting work.

2. Addressing Oil Filter Issues

Remove the Oil Filter
- Use an oil filter wrench to carefully remove the oil filter.

- Use a socket set to check if the drain plug is loose; tighten to the manufacturer's torque specification (typically around 20-25 ft-lbs).
Check the Oil Pan
- Inspect for cracks or damage. If damaged, replace the oil pan.
- If no damage is found, clean the area thoroughly, then reinstall the drain plug with a new washer if needed.

4. Replacing Valve Cover Gasket

Remove Components
- Remove any components obstructing access to the valve cover (e.g., intake manifold, ignition coils).
Replace the Gasket
- Unbolt the valve cover using a socket set.
- Carefully remove the old gasket and clean the mating surfaces.
- Place a new gasket and reassemble the valve cover, tightening to the manufacturer's torque specification.
