Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, rags, and a flashlight.
Park the vehicle on a level surface and allow the engine to cool.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Oil Filter

Sub-steps:
1. Place an oil catch pan under the oil filter.
2. Use an oil filter wrench to remove the old oil filter.
3. Apply a small amount of fresh oil to the rubber gasket of the new filter.
4. Install the new oil filter by hand, ensuring it is snug (do not overtighten).

3. Repair or Replace Valve Cover Gaskets

Sub-steps:
1. Remove any necessary components obstructing access to the valve covers (e.g., air intake, wiring harness).
2. Unbolt the valve cover using a socket set.
3. Clean the mating surfaces of the valve cover and cylinder head with a clean rag.
4. Install new gaskets, ensuring proper alignment.
5. Reinstall the valve cover and torque the bolts to the manufacturer's specifications (usually around 8-10 ft-lbs).

4. Inspect and Repair Oil Pan

Sub-steps:
1. Drain the oil using the oil catch pan.
2. Remove the oil pan by unbolting it from the engine block.
3. Clean the oil pan and the engine block surface with a solvent.
4. Replace the oil pan gasket or sealant as required.
5. Reinstall the oil pan, ensuring all bolts are torqued to specifications.

5. Check Front and Rear Main Seals

Sub-steps:
1. If oil leaks persist, inspect the front and rear main seals.
2. Remove the harmonic balancer (for front seal) or transmission (for rear seal) as needed.
3. Replace the seals with new ones, ensuring a proper fit.
4. Reassemble any removed components, following torque specifications.
