Solution

1. Preparation

Gather tools: socket set, oil catch pan, torque wrench, engine oil, new oil filter, and rags.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Drain Oil

Place the oil catch pan under the oil drain plug.
Remove the drain plug using a socket wrench and allow the oil to fully drain into the pan.
Clean the drain plug and inspect for wear or damage.

3. Replace Oil Filter

Locate the oil filter and use an oil filter wrench to remove it.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand until snug, then tighten according to the manufacturer's specifications.

4. Inspect and Replace Gaskets

If the valve cover gasket is leaking, remove the valve cover by unbolting it.
Clean the mating surfaces and install a new gasket.
Reinstall the valve cover, ensuring it is torqued to the specified value.

5. Reinstall Drain Plug and Fill Oil

Reinstall the oil drain plug and tighten it to the manufacturer’s torque specification.
Fill the engine with new oil using the correct type and viscosity as specified in the owner's manual.
Start the engine and let it idle for a few minutes to circulate the oil.

6. Check for Leaks

After running the engine, check around the oil filter, drain plug, and gaskets for any signs of leaking oil.
If no leaks are found, clean any spilled oil and dispose of the old oil and filter properly.
