Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid any electrical issues while working.

2. Identify and Remove the Leaking Component

Oil Filter Replacement:
- Use an oil filter wrench to remove the old oil filter. Ensure the old O-ring comes off with it.
- Install the new oil filter by applying a thin layer of new oil to the O-ring and tightening it to hand-tight plus a quarter turn.
Oil Drain Plug Replacement:
- Use a socket wrench to remove the oil drain plug from the oil pan.
- Inspect the drain plug for damage and replace it if necessary.
- Clean the area around the drain hole before reinstalling the plug, ensuring a proper seal.
Gasket/Seal Replacement:
- If the leak is from a gasket or seal (like the valve cover or oil pan), remove the affected component by unbolting it.
- Clean the mating surfaces thoroughly to remove old gasket material.
- Apply a new gasket or sealant as recommended by the manufacturer.
- Reinstall the component and torque to the manufacturer’s specifications.

3. Refill Engine Oil

Refill the engine with the appropriate type and amount of oil as specified in the owner’s manual.
Run the engine for a minute and check for leaks around the repaired areas.
