Solution

1. Preparation

Gather tools and materials: Socket set, torque wrench, oil catch pan, clean rags, and engine oil.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Identify and Fix Oil Leak

Sub-step 1: Clean the affected area in the engine bay with a degreaser to remove old oil residue.
Sub-step 2: If leaks are detected at gaskets (e.g., valve cover gasket), remove the affected components to access the gasket.
Sub-step 3: Replace the faulty gasket with a new one, ensuring to torque it to the manufacturer’s specifications (use torque wrench as required).
Sub-step 4: If the oil filter is leaking, replace it with a new filter, applying a small amount of oil to the rubber O-ring before installation.

3. Refill Engine Oil

Sub-step 1: If the oil level is low, refill the engine with the appropriate type and grade of oil as specified by the manufacturer.
Sub-step 2: Start the engine and allow it to run for a few minutes, then check for leaks again.

4. Clean Up

Sub-step 1: Use clean rags to wipe any spilled oil and remove any tools from the engine bay.
Sub-step 2: Dispose of any used oil and filters properly at a recycling center.
