Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues while working.

2. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter, tightening it by hand until snug.

3. Repair Oil Pan Gasket

Drain the engine oil using a drain pan; remove the oil drain plug with a socket set.
Remove the oil pan by unscrewing the bolts using a ratchet and socket.
Clean the mating surfaces of the oil pan and engine block with a gasket scraper.
Apply a new gasket or silicone sealant to the oil pan.
Reinstall the oil pan and torque the bolts to the manufacturer's specifications (typically around 10-20 ft-lbs).
Reinstall the oil drain plug and ensure it is secure.

4. Replace Valve Cover Gasket (if needed)

Remove any components obstructing access to the valve cover (e.g., intake hoses).
Unscrew the valve cover bolts and lift off the valve cover.
Remove the old gasket and clean the surfaces.
Place the new gasket on the valve cover and reinstall it, torquing the bolts to the specified value.

5. Refill Engine Oil

Pour the appropriate type and amount of new engine oil into the engine.
Start the engine and let it idle for a few minutes, checking for any leaks around the oil filter and oil pan.
