Solution

1. Preparation

Gather necessary tools and materials.
Safety gear: gloves and safety glasses.
Ensure the engine is cool and parked on a level surface.

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 fully drain.
Reinstall the drain plug and torque to the manufacturer’s specifications (typically around 25 Nm).

3. Replace Gaskets/Seals

Valve Cover Gasket:
- Remove any engine covers to access the valve cover.
- Unscrew the valve cover bolts using a socket set.
- Carefully lift the valve cover off and remove the old gasket.
- Clean the mating surfaces of the valve cover and cylinder head.
- Place a new valve cover gasket and reinstall the valve cover, tightening bolts in a crisscross pattern to the specified torque (usually around 10 Nm).
Oil Pan Gasket:
- If the oil pan gasket is faulty, remove the oil pan by unscrewing the bolts around the perimeter.
- Clean the oil pan and engine block surfaces thoroughly.
- Apply a new gasket or sealant as per manufacturer specifications.
- Reinstall the oil pan and torque bolts to specifications (usually around 10-15 Nm).

4. 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 oil filter.
Install the new oil filter hand-tight, then give it an additional 3/4 turn.

5. Refill Engine Oil

Pour in the recommended type and amount of new engine oil through the oil fill cap.
Start the engine and let it idle for a few minutes to circulate the oil.
Turn off the engine and check for leaks around the replaced components.
