Solution

1. Preparation

Tools Required:
- Socket set
- Oil catch pan
- Clean rags
- OBD-II scanner (if error codes are present)
Safety Warnings:
- Disconnect the battery before working on electrical components.
- Allow the engine to cool before beginning work.

2. Address Oil Leaks

Identify Source of Leak:
- Clean the engine area with degreaser to remove old oil.
- Start the engine and observe for leaks.
Replace Gaskets/Seals:
- If leaks are found at gaskets (valve cover, oil pan), remove the affected component.
- Clean surfaces and apply a new gasket or sealant as specified by the manufacturer.
- Reassemble and torque bolts to manufacturer specifications.

3. Change Engine Oil

Drain Old Oil:
- Position an oil catch pan under the oil pan.
- Remove the oil drain plug and allow old oil to drain completely.
- Replace the drain plug and torque it to specification.
Replace Oil Filter:
- Use an oil filter wrench to remove the old filter.
- Apply a bit of new oil to the rubber gasket of the new filter.
- Install the new filter and hand-tighten it.
Add New Oil:
- Use the manufacturer-recommended oil type and viscosity.
- Pour the new oil into the engine through the oil filler cap.
- Check the oil level with the dipstick and adjust as necessary.
