Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, oil catch pan, rags, and safety goggles.
Ensure the vehicle is parked on a flat surface and the engine is cool before beginning repairs.

2. Address Oil Leaks

Sub-step 1: Replace the Valve Cover Gasket
- Remove the engine cover (if applicable).
- Unbolt the valve cover and carefully lift it off.
- Clean the mating surfaces and remove the old gasket.
- Install a new gasket and reassemble the valve cover, tightening bolts to manufacturer torque specifications (usually around 7-10 ft-lbs).
Sub-step 2: Check and Replace Oil Pan Gasket
- Drain the engine oil using an oil catch pan.
- Remove the oil pan bolts and carefully detach the oil pan.
- Clean the surfaces and replace the old gasket with a new one.
- Reinstall the oil pan and torque bolts to manufacturer specifications (typically 7-10 ft-lbs).

3. Inspect and Replace Other Components

Sub-step 1: Replace Oil Filter
- Locate the oil filter and remove it using an oil filter wrench.
- Apply a thin layer of oil to the rubber gasket of the new filter and install it, ensuring it is snug but not over-tightened.
Sub-step 2: Refill Engine Oil
- Refill the engine with the appropriate type and amount of oil (typically 0W-20 or 5W-20 for this model).
- Start the engine and let it run for a few minutes, checking for any leaks.
