Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety.

2. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber O-ring of the new filter.
Install the new oil filter by hand, tightening it according to the manufacturer's specifications (usually hand-tight plus a quarter turn).

3. Tighten or Replace Drain Plug

Use a socket wrench to tighten the oil drain plug if it is loose.
If the drain plug is damaged, remove it and replace it with a new one, ensuring a proper seal.

4. Inspect and Replace Gaskets or Seals

If the oil leak originates from the oil pan, remove the oil pan by unbolting it from the engine.
Clean the mating surfaces and replace the oil pan gasket.
If the leak is from the valve cover, remove the valve cover, replace the gasket, and reassemble.
For main seals, consult specific service procedures as they often require more extensive disassembly.

5. Refill Engine Oil

Once all repairs are completed, refill the engine with the appropriate grade of oil as specified in the owner's manual.
Start the engine and allow it to run for a few minutes, checking for leaks around the repaired areas.
