Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Clean

Sub-steps:
- Remove any debris or dirt from the engine bay using a vacuum or compressed air.
- Inspect all accessible components for oil residue and identify the source of the leak.

3. Repairing Oil Leaks

Sub-steps:
- If the oil filter is leaking, replace it with a new one. Use an oil filter wrench for removal.
- If oil is leaking from gaskets (e.g., valve cover or oil pan), remove the affected component:
  - Valve Cover Gasket:
    1. Remove the valve cover bolts with a socket set (torque values typically around 7-9 ft-lbs, check manual).
    2. Replace the old gasket with a new one and reassemble.
  - Oil Pan Gasket:
    1. Drain the engine oil and remove the oil pan bolts.
    2. Clean the mating surfaces and install the new gasket.
    3. Reassemble and refill with oil.

4. Verify Seals and Connections

Sub-steps:
- Inspect all connections, including oil lines, for tightness and integrity.
- Replace any damaged or worn seals.

5. Refill Engine Oil

Add the recommended engine oil type as specified in the owner's manual.
Start the engine and allow it to run for a few minutes, then check for leaks.
