Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues.

2. Identify and Repair Leaks

Sub-steps:
1. Clean the engine bay with a degreaser to improve visibility of leaks.
2. Run the engine and observe for any fresh oil leaks.
3. Tighten any loose bolts or connections on the valve cover or oil filter.
4. Replace any faulty gaskets or seals identified during inspection.
Tools Required: Socket set, torque wrench, oil filter wrench, rags for cleaning.

3. Replace Valve Cover Gasket (if necessary)

Sub-steps:
1. Remove any components obstructing access to the valve cover (e.g., air intake, wiring harness).
2. Unbolt the valve cover using a socket wrench.
3. Remove the old gasket and clean the mating surfaces thoroughly.
4. Place the new gasket onto the valve cover and reattach it, ensuring proper torque specifications (typically around 10-12 Nm).
Tools Required: Socket set, gasket scraper, torque wrench.

4. Change Oil and Filter
