Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Identify and Fix Oil Leaks

Locate the Source of the Leak
- Use a clean cloth to wipe areas suspected of leaking.
- Start the engine and observe for any fresh oil seeping.
Replace Gaskets and Seals
- If leaks are found at the valve cover, remove the cover using a socket set.
- Clean the mating surfaces thoroughly.
- Install a new gasket and reattach the valve cover, torqueing bolts to manufacturer specifications (typically around 10-15 ft-lbs).
Inspect and Replace the Oil Filter
- Use an oil filter wrench to remove the old filter.
- Lubricate the rubber gasket on the new oil filter with fresh oil.
- Install the new filter and tighten according to specifications (usually hand-tight is sufficient).

3. Address Oil Consumption

Change Engine Oil
- Drain the old oil using a drain pan, ensuring to dispose of it properly.
- Replace with the correct grade of oil (typically 5W-30 for this model).
- Refill the engine with the appropriate amount of oil (check owner's manual for specifics).

4. Monitor Engine Temperature

If overheating is suspected, check the coolant level and condition.
Replace coolant if it appears dirty or low, and inspect the radiator for blockages or leaks.
