Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Replace Oil Filter (if leaking)

Tools required: Oil filter wrench, socket set, drain pan.
Place the drain pan under the oil filter.
Use the oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand until snug, then tighten slightly with the wrench (do not overtighten).

3. Tighten or Replace Drain Plug

Tools required: Socket set, torque wrench.
Place the drain pan under the oil pan.
Inspect the drain plug for tightness; if loose, tighten to manufacturer specifications (typically around 25-30 Nm).
If the plug is damaged or stripped, replace it with a new one.

4. Replace Valve Cover Gasket (if leaking)

Tools required: Socket set, torque wrench, gasket scraper.
Remove any covers obstructing access to the valve cover.
Unscrew the valve cover bolts and carefully lift the valve cover off.
Remove the old gasket and clean the mating surfaces.
Install the new gasket, ensuring it is seated properly.
Reinstall the valve cover, tightening bolts to manufacturer torque specifications (usually around 10-15 Nm).
