Solution

1. Preparation

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

2. Inspect and Replace Oil Filter

Tools Required: Oil filter wrench, oil catch pan, socket set.
Sub-steps:
1. Place the oil catch pan under the oil filter area.
2. Using the oil filter wrench, carefully remove the oil filter.
3. Inspect the rubber O-ring on the old filter for damage.
4. Apply a thin layer of clean oil to the new oil filter O-ring.
5. Install the new oil filter, tightening it to the manufacturer's specified torque (typically hand-tight plus 3/4 turn).

3. Tighten or Replace Oil Drain Plug

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Place the oil catch pan under the oil drain plug.
2. Inspect the drain plug for wear or damage.
3. If loose, tighten the plug to the correct torque specification (usually around 25 Nm).
4. If damaged, replace the oil drain plug and gasket.

4. Inspect and Replace Gaskets/Seals

Tools Required: Gasket scraper, seal puller, torque wrench.
Sub-steps:
1. Locate the valve cover and timing cover gaskets.
2. Remove any components obstructing access to these gaskets.
3. Carefully scrape off the old gasket material from the mating surfaces.
4. Install new gaskets, ensuring proper alignment.
5. Reinstall components and torque to specifications.

5. Final Inspection

Tools Required: Clean rags.
Sub-steps:
1. Clean any oil residue from the engine and undercarriage.
2. Start the engine and allow it to reach operating temperature.
3. Check for any signs of oil leaking from previously inspected areas.
