Solution

1. Preparation

Gather tools and materials: Oil catch pan, socket set, rags, OBD-II scanner, and replacement gaskets or seals as needed.
Ensure the engine is cool and disconnect the battery to prevent electrical issues.

2. Identify and Fix Leaks

Inspect Oil Filter:
- Remove the oil filter and check the rubber O-ring for damage.
- Replace with a new filter if necessary, ensuring the O-ring is intact.
Check Drain Plug:
- Use a socket wrench to tighten the oil drain plug. If leaking persists, replace the washer.

3. Replace Damaged Gaskets or Seals

Valve Cover Gasket Replacement:
- Remove any components obstructing access to the valve cover.
- Unbolt the valve cover and remove it carefully.
- Clean the mating surfaces of the valve cover and engine.
- Install a new gasket and reassemble the valve cover, tightening bolts to manufacturer specifications (usually around 10-15 lb-ft).
Oil Pan Gasket Replacement:
- Support the engine with a jack and remove any components that obstruct the oil pan.
- Unbolt the oil pan and remove it while ensuring the old gasket is removed completely.
- Clean the surfaces and install a new gasket before reassembling the oil pan, tightening bolts to manufacturer specifications.

4. Final Checks

Refill oil if necessary and check for leaks after repairs.
Reconnect the battery and clear any error codes using the OBD-II scanner.
