Solution

1. Preparation

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

2. Address Oil Filter Leak

Sub-steps:
1. Locate the oil filter and place an oil catch pan underneath.
2. Using an oil filter wrench, remove the oil filter.
3. Inspect the rubber O-ring on the old filter for damage. Clean the mounting surface.
4. Apply a small amount of new oil to the O-ring of the new filter.
5. Install the new oil filter by hand and tighten it to the manufacturer's specifications (usually 3/4 turn after the O-ring makes contact).

3. Fix Oil Drain Plug Leak

Sub-steps:
1. Locate the oil drain plug at the bottom of the oil pan.
2. Use a socket wrench to remove the drain plug. Allow any remaining oil to drain into the catch pan.
3. Inspect the drain plug for wear and replace the crush washer if necessary.
4. Reinstall the drain plug and tighten it to the specified torque (usually around 25-30 ft-lbs).

4. Replace Valve Cover Gaskets

Sub-steps:
1. Remove any components obstructing access to the valve covers (e.g., intake ducts, ignition coils).
2. Unbolt the valve cover and carefully lift it off, taking care not to damage the gasket surface.
3. Remove the old gaskets and clean the surfaces thoroughly.
4. Place new gaskets on the valve cover and reassemble.
5. Torque the valve cover bolts to the manufacturer's specifications (typically around 8-10 ft-lbs).
