Solution

1. Preparation

Tools Required: Socket set, oil filter wrench, torque wrench, rags, oil catch pan
Ensure the vehicle is parked on a level surface and the engine is cool before beginning work.

2. Drain Engine Oil

Place an oil catch pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the oil to completely drain into the pan.
Replace the drain plug and torque to the manufacturer's specifications (usually around 25 Nm).

3. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber O-ring of the new filter.
Install the new oil filter and tighten it by hand until snug, then turn it an additional 3/4 turn.

4. Inspect and Replace Gaskets/Seals

If the valve cover gasket or oil pan gasket is leaking, remove the affected component.
Clean the mating surfaces thoroughly to remove old gasket material.
Install a new gasket, ensuring proper alignment, and torque the bolts to specifications (typically around 10-15 Nm for valve covers).
For oil pan gasket replacements, remove the oil pan, clean it, and install a new gasket, torquing the pan bolts to the specified torque.

5. Refill Engine Oil

Remove the oil filler cap and pour in the new engine oil, following the manufacturer's specifications for oil type and capacity (usually around 4-5 liters).
Replace the oil filler cap securely.

6. Check for Leaks

Start the engine and let it idle for a few minutes.
Check under the vehicle and around the engine for any signs of oil leaks.
If no leaks are present, turn off the engine and check the oil level using the dipstick, adding oil if necessary.
