Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, flashlight, fluid catch pan, safety glasses, gloves.
Safety Warnings: Allow the engine to cool before beginning any work; disconnect the battery if working on electrical components.

2. Resolve Engine Oil Leak

Identify Leak Source: If oil is leaking, determine where it’s coming from (e.g., oil pan, valve cover gasket).
Replace Gasket or Seal: Remove the affected component, clean the surface, apply a new gasket or seal, and reassemble.
Refill Engine Oil: After repairs, refill engine oil to the appropriate level.

3. Addressing Overheating Brakes

Inspect Brake System: Remove the wheel to access the brake components; check pads and rotors.
Replace Worn Components: If excessive wear is found, replace brake pads and possibly rotors.
Inspect Brake Lines: Check for any signs of fluid leaks in the brake lines and replace as necessary.

4. Repairing Exhaust System

Locate the Leak: If an exhaust leak is suspected, use a smoke machine or visual inspection to locate the source.
Seal or Replace: Depending on the severity, either seal minor leaks with exhaust tape or replace damaged sections of the exhaust.
