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 the Leak Source

A. Oil Filter Inspection and Replacement

Locate the oil filter on the engine.
Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of engine oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand, tightening it according to manufacturer's specifications (typically hand-tight plus 3/4 turn).
Refill the engine with the correct type and amount of oil (refer to owner's manual).

B. Valve Cover Gasket Replacement

Remove the engine cover if applicable, by unscrewing any bolts.
Unbolt the valve cover using a socket set.
Carefully lift the valve cover off; scrape off any old gasket material from the mating surfaces.
Apply a new valve cover gasket to the valve cover or the engine.
Reinstall the valve cover and torque bolts to manufacturer specifications (usually around 7-9 ft-lbs).
Reattach the engine cover if applicable.

C. Oil Pan Gasket Replacement

Drain the engine oil by removing the oil drain plug with a socket set.
Unbolt the oil pan using the appropriate socket.
Carefully remove the oil pan, scraping away old gasket material.
Install a new oil pan gasket and reinstall the oil pan, torquing bolts to manufacturer specifications (typically around 12-16 ft-lbs).
Reinstall the drain plug and refill the engine with oil.

3. Final Checks

Reconnect the negative battery terminal.
Start the engine and allow it to run for a few minutes.
Check for leaks around the repaired areas.
