Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and disconnect the battery.
Lift the vehicle using a jack and secure with jack stands.

2. Identify and Repair Oil Leaks

Inspect Gaskets and Seals
- Check the valve cover gasket, oil pan gasket, and other engine seals for damage.
- If damaged, remove the old gasket using a scraper and clean the surface.
- Install new gaskets, applying the specified torque to the bolts (refer to manufacturer specifications).
Replace Oil Filter
- Locate the oil filter; use an oil filter wrench to remove it.
- Lubricate the rubber O-ring of the new oil filter with a little new oil.
- Install the new oil filter hand-tight.

3. Replace Engine Oil

Drain Old Oil
- Place an oil catch pan under the oil pan and remove the drain plug.
- Allow old oil to completely drain out.
Add New Oil
- Reinstall the drain plug and tighten to manufacturer specifications.
- Pour the recommended grade of engine oil into the engine using a funnel.
- Check the oil level with the dipstick and add oil as necessary.

4. Test for Proper Operation

Reconnect the battery.
Start the engine and let it idle for a few minutes while checking for leaks.
Observe the engine for any smoke or unusual smells.
