Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and is in park or neutral with the parking brake engaged.
Disconnect the battery to prevent any electrical shorts during the inspection.

2. Identify and Repair Oil Leaks

Sub-steps:
1. Clean the engine bay using a degreaser to make leaks more visible.
2. Use a flashlight to inspect gaskets, seals, and hoses for any signs of oil seepage.
3. Replace any damaged gaskets or seals found during inspection (e.g., valve cover gasket, oil pan gasket).
4. Tighten any loose bolts on the engine that may be contributing to leaks.
Tools Required: Socket set, torque wrench, oil catch pan, rags.

3. Change Engine Oil

Sub-steps:
1. Remove the drain plug from the oil pan and allow the old oil to completely drain into the catch pan.
2. Replace the drain plug and tighten to the manufacturer’s specified torque.
3. Replace the oil filter with a new one, ensuring the rubber O-ring is lubricated and properly seated.
4. Add the correct type and amount of new oil as specified in the owner’s manual.
Tools Required: Oil filter wrench, oil catch pan, socket set, funnel.

4. Clean Exhaust Components

Sub-steps:
1. Inspect the exhaust system for oil residue, particularly around the manifold and catalytic converter.
2. Clean any oil residue using a suitable cleaner and a wire brush, ensuring all surfaces are free from oil.
Tools Required: Wire brush, degreaser, rags.
