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 Repair Engine Components

Inspect for Oil Leaks:
- Check oil filter, drain plug, and valve cover gaskets for leaks.
- Clean any oil residue and replace gaskets if necessary.
Replace Damaged Hoses:
- Look for frayed or cracked hoses in the cooling system or vacuum lines.
- Replace any damaged hoses with OEM-equivalent parts.

3. Brake System Inspection and Service

Inspect Brake Pads and Rotors:
- Remove the wheel to access the brake components.
- Measure the thickness of the brake pads; replace if below manufacturer specifications.
- Inspect rotors for signs of warping or excessive wear. Replace if necessary.

4. Exhaust System Inspection

Check for Leaks:
- Inspect exhaust manifold, gaskets, and pipes for damage or rust.
- Repair or replace damaged components to prevent exhaust fumes from entering the cabin.

5. Reassemble and Test

Reinstall any components removed during inspection.
Reconnect the battery and start the engine.
Allow the vehicle to warm up and monitor for any further smells or leaks.
