Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during repair.

2. Identify and Repair the Leak Source

Oil Filter Replacement:
- Use an oil filter wrench to remove the old oil filter.
- Apply a thin layer of oil to the rubber gasket of the new filter.
- Install the new oil filter by hand until snug, then tighten an additional 3/4 turn.
Replace Drain Plug Washer:
- Use a socket wrench to remove the oil drain plug.
- Replace the washer on the drain plug if worn or damaged.
- Reinstall the drain plug and tighten to 20-25 ft-lbs.
Gasket Replacement:
- For the valve cover gasket, remove the valve cover bolts using a socket set.
- Carefully lift the valve cover off and replace the old gasket with a new one.
- Reinstall the valve cover, ensuring proper alignment, and torque the bolts to the manufacturer's specifications (typically 7-9 ft-lbs).
Oil Pan Gasket Replacement:
- Drain the engine oil.
- Remove the oil pan bolts and gently tap the pan to loosen it.
- Replace the old gasket with a new one and reinstall the oil pan, tightening the bolts to the specified torque (usually around 10-12 ft-lbs).

3. Refill Engine Oil

Refill the engine with the appropriate type and amount of oil as specified in the owner’s manual (usually 0W-20 for this model).
Start the engine and let it run for a few minutes while checking for leaks.
