Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative terminal of the battery for safety.

2. Identify Leak Source

Sub-step 1: Clean the engine and undercarriage thoroughly using an engine degreaser.
Sub-step 2: Start the engine and allow it to idle while checking for fresh oil leaks.
Sub-step 3: Use a flashlight to inspect areas where oil appears to be leaking.

3. Replace Faulty Components

Sub-step 1: If the oil filter is leaking, remove it using an oil filter wrench and install a new one. Ensure the new filter is primed with oil before installation.
Sub-step 2: If the drain plug is leaking, remove it with a socket wrench, replace the washer, and re-torque it to the manufacturer's specifications (typically around 20-25 ft-lbs).
Sub-step 3: For leaking gaskets or seals, remove the affected component (e.g., oil pan, valve cover) and replace the gasket or seal as per repair manual specifications.

4. Refill Engine Oil

Sub-step 1: After repairs, refill the engine with the correct type and amount of oil as specified in the owner's manual (usually 5W-30 or 0W-20).
Sub-step 2: Use a funnel to avoid spills and check the oil level with the dipstick after filling.

5. Final Checks

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the engine and check for leaks around the repaired areas.
Sub-step 3: Take the vehicle for a short test drive, then recheck the oil level and for any signs of leaks.
