Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Identify and Replace Leaking Components

Oil Filter:
- Remove the old oil filter using an oil filter wrench.
- Apply a thin layer of oil on the rubber gasket of the new filter.
- Install the new oil filter and tighten it according to the manufacturer's specifications (usually hand-tight plus a quarter turn).
Oil Drain Plug:
- Place a drain pan under the oil pan.
- Remove the drain plug with a socket wrench, allowing oil to drain completely.
- Inspect the drain plug and washer for damage; replace if necessary.
- Reinstall the drain plug and torque it to the manufacturer’s specifications (typically around 25 Nm).
Inspect and Replace Gaskets as Needed:
- If the oil pan or valve cover gaskets are leaking, remove the affected components.
- Clean the mating surfaces thoroughly to ensure a good seal.
- Install new gaskets and reassemble the components, ensuring proper torque settings.

3. Refill Engine Oil

After all repairs are made, refill the engine with the appropriate type and amount of oil as specified in the owner's manual.

4. Final Checks

Reconnect the battery.
Start the engine and let it idle for a few minutes while checking for any signs of leaks.
