Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical hazards.

2. Identify and Repair Leaks

Tighten any loose bolts or fasteners on the oil pan, valve cover, or other suspected areas.

3. Replace Gaskets or Seals

Parts Required: New gaskets or seals (based on the leak location)
Remove the components as necessary (e.g., valve cover, oil pan) to access the gaskets.
Scrape off old gasket material and clean the surfaces thoroughly.
Install the new gasket or seal, ensuring proper alignment.
Reassemble the components and torque to manufacturer specifications.

4. Check and Change Oil

Tools Required: Oil filter wrench, oil catch pan
Drain the old oil using an oil catch pan and replace it with new oil, ensuring the correct type is used as specified in the owner's manual.
Replace the oil filter if necessary.
