Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the battery to ensure safety while working on electrical components.

2. Locate the Leak

Sub-steps:
- After cleaning the engine, run the engine until it reaches normal operating temperature.
- Inspect the engine with a UV light if using dye, or look for fresh oil residue.
- Identify the source of the leak (e.g., oil filter, valve cover gasket, oil pan).

3. Repair the Leak

For Oil Filter Leak:
- Remove the oil filter using an oil filter wrench.
- Install a new oil filter, ensuring the rubber O-ring is lubricated and properly seated.
- Tighten to manufacturer specifications (usually hand-tight plus a quarter turn).
For Valve Cover Gasket Leak:
- Remove any components obstructing access (e.g., intake manifold, ignition coils).
- Unbolt the valve cover and remove it carefully.
- Clean the gasket surfaces thoroughly.
- Install a new valve cover gasket, ensuring proper alignment, and reattach the valve cover, tightening bolts to manufacturer torque specifications.
For Oil Pan Leak:
- Drain the engine oil completely.
- Remove the oil pan bolts and gently pry the oil pan away from the engine block.
- Clean the old gasket surface from both the oil pan and engine block.
- Apply a new gasket or sealant as specified by the manufacturer and reattach the oil pan, tightening bolts to the specified torque.

4. Refill and Check

Refill the engine with the appropriate type and amount of engine oil.
Reconnect the battery and start the engine, checking for leaks around the repaired areas.
