Solution

1. Preparation

Tools Required: Socket set, wrench set, oil catch pan, rags, OBD-II scanner.
Safety Warnings: Disconnect the battery before working on electrical systems, and allow the engine to cool before inspecting the engine compartment.

2. Identify and Fix Oil Leaks

Step 1: Clean the engine bay using a degreaser to remove old oil residue for better visibility.
Step 2: Tighten any loose bolts or screws on the oil filter and drain plug.
Step 3: Replace the oil filter if it shows signs of wear or leakage.
Step 4: If the valve cover gasket is damaged, remove the valve cover by loosening the bolts, clean the mating surfaces, and replace the gasket.
Step 5: Reassemble all components and top off engine oil if necessary.

3. Replace Engine Oil

Step 1: Drain the old oil into an oil catch pan.
Step 2: Replace the oil filter with a new one.
Step 3: Refill the engine with the appropriate type and amount of oil (typically 0W-20 for a 2.5L engine).
Step 4: Start the engine and let it idle for a few minutes, then recheck the oil level, adding more if necessary.
