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 avoid any electrical issues.

2. Inspect and Clean

Tools Required: Oil catch pan, rags, cleaning solvent.
Clean any oil residue from the engine bay with a suitable cleaning solvent.
Inspect for leaks again after cleaning to identify the source.

3. Replace Faulty Components

Valve Cover Gasket Replacement:
1. Remove any components obstructing access to the valve cover (e.g., air intake hose).
2. Remove the valve cover bolts in a crisscross pattern to avoid warping.
3. Carefully lift off the valve cover and remove the old gasket.
4. Clean the mating surfaces thoroughly.
5. Install the new gasket and reposition the valve cover.
6. Torque the valve cover bolts to the manufacturer's specifications (usually around 8 Nm, but check the service manual).
Oil Filter Replacement:
1. Remove the old oil filter using an oil filter wrench.
2. Apply a small amount of new engine oil to the rubber O-ring of the new filter.
3. Install the new oil filter by hand-tightening it.

4. Refill Engine Oil

Tools Required: Funnel, new engine oil.
Drain any old oil if necessary before refilling.
Refill with the appropriate grade of engine oil as specified in the owner's manual.

5. Final Checks

Reconnect the battery and start the engine.
Check for leaks around the valve cover and oil filter.
Make sure the engine sounds normal and there are no warning lights.
