Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery if necessary for electrical safety.

2. Identify and Replace Leaking Component

Oil Filter Replacement
- Remove the old oil filter using an oil filter wrench.
- Clean the mounting surface and apply a thin layer of oil to the rubber gasket of the new filter.
- Install the new oil filter, tightening it by hand until snug.
Oil Drain Plug Replacement
- Place a drain pan under the oil pan.
- Use a socket wrench to remove the oil drain plug and allow the old oil to drain completely.
- Inspect the drain plug for damage; replace if necessary.
- Install the drain plug with a new washer, torquing it to the manufacturer’s specifications (typically around 20 ft-lbs).
Valve Cover Gasket Replacement
- Remove any components obstructing access to the valve cover (e.g., intake manifold).
- Unbolt the valve cover and carefully lift it off.
- Remove the old gasket material from the cover and engine surface.
- Install a new gasket, ensuring proper alignment, then reassemble the valve cover.
