Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.
Tools Required: Socket set, oil filter wrench, torque wrench, rags for cleanup.

2. Identify Source of Leak

Clean the engine area with a degreaser to remove oil residue.
Start the engine and allow it to run for a few minutes.
Inspect the cleaned area for fresh oil seeping from any gaskets or seals.

3. Repair Leaks

Oil Filter Replacement:
- Use the oil filter wrench to remove the old oil filter.
- Lubricate the rubber O-ring of the new oil filter with engine oil.
- Install the new oil filter and tighten it to manufacturer specifications (usually hand-tight plus 3/4 turn).
Drain Plug Replacement:
- Use a socket set to remove the drain plug if it is leaking. Inspect the washer and replace if worn.
- Reinstall the drain plug and tighten to the specified torque (usually around 25 ft-lbs).
Gasket or Seal Replacement:
- If a valve cover or oil pan gasket is leaking, remove necessary components to access the gasket.
- Carefully remove the old gasket and clean the surfaces of any residue.
- Apply a new gasket or sealant as per manufacturer specifications and reassemble components, ensuring proper torque values are followed.

4. Refill Engine Oil

After repairs, refill the engine with the appropriate type and amount of oil as specified in the owner’s manual.
Check for leaks again after running the engine for a few minutes.
