1. Preparation

Tools Required: Socket set, screwdrivers, oil catch pan, UV light, cleaning rags, engine oil, and a dipstick.
Safety Warnings: Ensure the engine is cool before starting any work. Wear gloves and safety goggles.

2. Identify and Clean Leak Area

Sub-steps:
1. Clean the area around the suspected leak source with engine degreaser.
2. Dry the area thoroughly to make it easier to identify the exact source of the leak.

3. Replace Gasket or Seal

Sub-steps:
1. If the leak is from the valve cover gasket:
  - Remove the valve cover by unscrewing the bolts (torque to specification on reinstallation).
  - Remove the old gasket and clean the mating surfaces.
  - Install the new gasket and reassemble the valve cover.
2. If the leak is from the oil pan:
  - Drain the engine oil into an oil catch pan.
  - Remove the oil pan by unscrewing the bolts.
  - Replace the oil pan gasket and reinstall the oil pan.

4. Replace Oil Filter

Sub-steps:
1. Unscrew the old oil filter, ensuring to catch any residual oil.
2. Apply a thin layer of new oil on the rubber gasket of the new oil filter.
3. Install the new oil filter and tighten it according to specifications.

5. Refill Engine Oil

Sub-steps:
1. Use a funnel to refill the engine with the appropriate type and amount of oil as specified in the owner's manual.
2. Check the oil level with the dipstick and add more oil if necessary.
