Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil drain pan, rags, OBD-II scanner
Park the vehicle on a level surface and turn off the engine. Allow it to cool completely before beginning work.
Disconnect the battery to avoid electrical issues.

2. Inspect and Repair Oil Leaks

Step 1: Identify the source of the oil leak.
- Clean the engine bay with a degreaser to better see any oil leaks.
- Use a flashlight to inspect around the valve cover, oil pan, and oil filter.
Step 2: Replace any faulty gaskets or seals.
- If the valve cover gasket is leaking, remove the valve cover by undoing the bolts (use the torque specifications for reinstallation).
- Replace the gasket and clean the mating surfaces before reassembly.
Step 3: Ensure the oil filter is properly installed.
- If the oil filter is loose or damaged, replace it with a new filter, ensuring it is tightened to the manufacturer’s specifications.

3. Change Oil and Filter

Step 1: Drain the old oil.
- Remove the oil drain plug using a socket set and allow the oil to drain into an oil pan.
Step 2: Replace the oil filter.
- Install the new oil filter after applying a small amount of new oil to the gasket for a better seal.
Step 3: Refill with clean engine oil.
- Refer to the owner’s manual for the correct oil type and capacity. Pour the new oil into the engine and check the level with the dipstick.
