Solution

1. Preparation

Gather tools and materials: socket set, oil catch pan, replacement oil filter, and engine oil.
Ensure the vehicle is parked on a level surface and the engine is cool before beginning work.

2. Addressing Oil Leaks

a. Clean the engine: Use a degreaser to clean any oil residue from the engine surface for better visibility of leaks.
b. Replace gaskets/seals: If leaks are found around the valve cover gasket or oil pan gasket, remove the old gasket, clean the mating surfaces, and install a new gasket. Torque to manufacturer specifications (typically 7-10 ft-lbs for valve cover).

3. Oil Change

a. Drain old oil: Place an oil catch pan under the oil pan, remove the drain plug, and allow the oil to completely drain.
b. Replace oil filter: Use an oil filter wrench to remove the old oil filter. Apply a little new oil to the rubber seal of the new filter and install it hand-tight.
c. Add new oil: Replace the drain plug, tighten it to manufacturer specifications (typically 20-30 ft-lbs), and refill the engine with the recommended oil type (usually 0W-20 for this model) using a funnel.

4. Final Checks

Start the engine and let it idle for a few minutes, checking for any leaks around the oil filter and drain plug.
Turn off the engine and recheck the oil level, adding oil if necessary.
