Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery if necessary for safety.

2. Address Oil Leaks

Inspect and Replace Gaskets/Seals:
- Identify any faulty gaskets or seals (valve cover gasket, oil pan gasket).
- Remove the components as necessary (e.g., valve cover).
- Clean the mating surfaces thoroughly.
- Apply a new gasket or sealant as per manufacturer's specifications.
Replace Oil Filter:
- Place an oil drain pan under the oil filter.
- Remove the old oil filter using an oil filter wrench.
- Apply a thin layer of oil on the rubber O-ring of the new filter.
- Install the new oil filter, tightening it to the manufacturer's torque specifications.

3. Change Engine Oil

Drain Old Oil:
- Remove the drain plug and allow the oil to completely drain into the pan.
- Replace the drain plug and tighten to the specified torque.
Add New Oil:
- Use the manufacturer-recommended oil type and capacity.
- Pour new oil into the engine and check the level with the dipstick.

4. Clean Up

Clean any oil spills in the engine compartment and dispose of oil and filter according to local regulations.
