Solution

1. Preparation

Gather tools and materials:
- Oil catch pan
- Socket set
- Torque wrench
- Clean rags
- Replacement gaskets or seals (if needed)
Ensure the engine is cool before starting.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Fix Leaks

Sub-steps:
1. If oil is found around the valve cover gasket, remove the bolts securing the valve cover using a socket set.
2. Carefully lift the valve cover and inspect the gasket for wear or damage. Clean the mating surfaces with a rag.
3. Replace the gasket with a new one, ensuring it is seated properly.
4. Reinstall the valve cover and torque the bolts to the manufacturer's specifications (typically 7-11 ft-lbs).

3. Check and Replace Oil Filter

Sub-steps:
1. Locate the oil filter using your vehicle's service manual.
2. Use an oil filter wrench to remove the filter. Allow any excess oil to drain into the catch pan.
3. Apply a thin layer of fresh oil to the rubber O-ring of the new filter.
4. Install the new filter, tightening it by hand until snug (avoid over-tightening).

4. Inspect Oil Pan

Sub-steps:
1. If oil is leaking from the oil pan, check for loose bolts with a socket set.
2. If the oil pan gasket is leaking, drain the engine oil into a catch pan and remove the oil pan.
3. Clean the surface and replace the oil pan gasket.
4. Reinstall the oil pan and torque the bolts to the manufacturer's specifications (typically 7-9 ft-lbs).

5. Refill Engine Oil

Sub-steps:
1. Ensure the oil drain plug is securely reinstalled.
2. Refill the engine with the recommended type and amount of oil (typically 5W-20 for this vehicle).
3. Start the engine and check for leaks around the oil filter and valve cover.
