Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, torque wrench, rags, UV dye (if needed), and replacement gaskets or sealant.
Ensure the engine is cool before beginning any work.

2. Address Visible Leaks

Sub-step 1: If oil is leaking from the valve cover gasket, remove the bolts securing the valve cover using a socket set.
Sub-step 2: Gently lift the valve cover off and inspect the gasket. Replace it if it is damaged or worn.
Sub-step 3: Clean the mating surfaces with a rag and apply a thin layer of gasket sealer if necessary.
Sub-step 4: Reinstall the valve cover and torque the bolts to the manufacturer's specifications (typically 7-10 ft-lbs).

3. Inspect and Replace Oil Filter

Sub-step 1: Locate the oil filter and ensure you have an oil filter wrench.
Sub-step 2: Remove the old oil filter, ensuring to catch any residual oil in a container.
Sub-step 3: Apply a small amount of new oil to the rubber O-ring of the new oil filter.
Sub-step 4: Install the new oil filter by hand until snug, then tighten it according to the manufacturer's specifications.

4. Check and Replenish Engine Oil

Sub-step 1: Remove the dipstick and wipe it clean.
Sub-step 2: Reinsert the dipstick, then remove it again to check the oil level.
Sub-step 3: If low, top up with the appropriate type of engine oil (typically 0W-20 for this model).
