Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, oil filter wrench, rags, engine oil, and replacement gaskets if needed.
Park the vehicle on a level surface and allow the engine to cool.
Disconnect the battery to ensure safety.

2. Identify and Fix the Leak Source

A. Oil Filter Replacement

Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of oil on the rubber gasket of the new filter.
Install the new oil filter, tightening it according to the manufacturer’s specifications.

B. Replace Oil Drain Plug

Place a drain pan underneath the oil pan.
Remove the oil drain plug using a socket, allowing oil to drain completely.
Inspect the drain plug for damage; replace if necessary.
Clean the area around the drain plug, then reinstall and tighten to the specified torque.

C. Gasket Replacement

If the valve cover gasket or oil pan gasket is leaking, remove the necessary components to access them.
Clean the mating surfaces thoroughly with a gasket scraper.
Install new gaskets, ensuring they are oriented correctly, and reassemble components.
Torque all fasteners to the manufacturer’s specifications.

3. Refill Engine Oil

After repairs, refill the engine with the appropriate type and amount of oil.
Check the dipstick to ensure the oil level is correct.
