Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Identify and Repair Oil Leak Source

A. Oil Filter Replacement

Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand until snug, then tighten according to manufacturer specifications (usually about 3/4 turn after the gasket makes contact).

B. Valve Cover Gasket Replacement

Remove any engine covers obstructing access to the valve covers.
Disconnect any electrical connectors or vacuum lines attached to the valve cover.
Unbolt the valve cover from the engine using a socket set, noting the torque specifications.
Carefully lift off the valve cover and remove the old gasket.
Clean the mating surfaces thoroughly.
Install the new gasket and reposition the valve cover, ensuring proper alignment.
Reinstall the bolts and tighten to manufacturer's torque specifications.

C. Oil Pan Gasket Replacement

Drain the engine oil using a drain pan and remove the oil pan bolts.
Carefully lower the oil pan to access the gasket.
Remove the old gasket material from both the oil pan and engine block surfaces.
Apply a new gasket or gasket maker according to manufacturer instructions.
Reinstall the oil pan and torque the bolts to specifications.

3. Inspect Oil Cooler Lines

Examine the oil cooler lines for any cracks or loose connections.
Replace any damaged lines or tighten fittings as needed.
