Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Wear safety gloves and glasses.

2. Identify the Leak Source

Sub-steps:
1. Clean the engine area with a degreaser to remove old oil residue.
2. Use a UV light to illuminate the engine and locate the leak source.

3. Replace Damaged Seals or Gaskets

Sub-steps:
1. If the valve cover gasket is leaking, remove the valve cover bolts using a socket wrench.
2. Carefully lift the valve cover off and replace the old gasket with a new one, ensuring it sits evenly in its groove.
3. Reinstall the valve cover and torque the bolts to the manufacturer's specifications (usually around 7-9 lb-ft, but verify with service manual).
4. If the oil pan is leaking, drain the oil before removal. Remove the oil pan bolts and gently pry it off.
5. Clean the mating surfaces and install a new gasket or sealant as specified by the manufacturer. Reattach the oil pan and torque the bolts to the specified value.

4. Replace Oil Filter (if necessary)

Sub-steps:
1. Use an oil filter wrench to remove the old oil filter.
2. Apply a small amount of new oil to the rubber gasket of the new filter.
3. Install the new oil filter by hand until snug, then tighten an additional three-quarters turn.

5. Refill Engine Oil

Sub-steps:
1. Replace the oil drain plug and tighten to the specified torque (usually around 20-25 lb-ft).
2. Refill the engine with the recommended oil type using a funnel (check the owner's manual for oil capacity).
