Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, engine cleaner, rags
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Identify and Replace Leaking Components

A. Oil Filter

Steps:
1. Remove the oil catch pan and place it under the oil filter.
2. Use an oil filter wrench to unscrew the old oil filter.
3. Apply a thin layer of fresh oil to the rubber gasket of the new oil filter.
4. Install the new oil filter by hand until snug, then tighten slightly with the wrench (do not over-tighten).

B. Drain Plug

Steps:
1. Place the oil catch pan under the oil drain plug.
2. Use the appropriate socket to remove the drain plug, allowing any excess oil to drain into the pan.
3. Inspect the drain plug and its gasket for damage; replace if necessary.
4. Reinstall the drain plug and torque to manufacturer specifications (typically around 20-25 lb-ft).

C. Gaskets and Seals

Steps:
1. If oil is leaking from the valve cover or oil pan, remove the respective components.
2. Clean the mating surfaces with engine cleaner and a rag.
3. Replace the old gasket or seal with a new one.
4. Reassemble the components, ensuring to torque bolts to specified values.

3. Refill Engine Oil

Steps:
1. Remove the oil filler cap and pour in the recommended type and amount of engine oil (typically 5W-20 or 5W-30).
2. Replace the oil filler cap securely.
