Solution

1. Preparation

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

2. Addressing the Leak Source

A. Oil Filter Replacement

Locate the oil filter on the engine.
Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil on the rubber gasket of the new oil filter.
Install the new oil filter by hand until snug, then tighten it an additional 3/4 turn.

B. Oil Pan Gasket Replacement

Drain the oil by removing the drain plug from the oil pan.
Remove any old gasket material from the oil pan and engine block using a scraper.
Place a new gasket on the oil pan.
Reinstall the oil pan, tightening the bolts to the manufacturer's specified torque (usually 10-15 ft-lbs).
Refill the engine with the appropriate oil type.

C. Valve Cover Gasket Replacement

Remove any components obstructing access to the valve cover.
Unscrew the valve cover bolts and lift off the valve cover.
Remove the old gasket from the valve cover and cylinder head.
Place a new gasket on the valve cover and reinstall.
Tighten the bolts to the specified torque (typically around 8-10 ft-lbs).

3. Reassembly

Reinstall any components removed for access.
Reconnect the battery.
Start the engine and check for leaks.
