Solution

1. Preparation

Gather tools and materials needed for the repair.
Tools Required:
- Socket set
- Torque wrench
- Oil catch pan
- Engine oil
- New oil filter
- Gasket scraper
Ensure the vehicle is parked on a level surface and the engine is cool before starting.

2. Address Oil Leaks

A. Valve Cover Gasket Replacement

Remove the engine cover (if equipped) by unscrewing any fasteners.
Disconnect any electrical connections or hoses that obstruct access to the valve cover.
Remove the valve cover bolts using a socket wrench and lift the valve cover off.
Clean the mating surface of the cylinder head and the valve cover with a gasket scraper.
Install a new valve cover gasket in the groove of the valve cover.
Reinstall the valve cover and torque the bolts to the manufacturer's specification (typically 7-9 lb-ft).
Reconnect any electrical connections or hoses and replace the engine cover.

B. Oil Filter and Drain Plug Check

Place an oil catch pan under the oil pan.
Remove the drain plug using a socket wrench and allow the oil to fully drain out.
Inspect the drain plug washer and replace if damaged.
Clean the drain plug threads and reinstall it, tightening it to the specified torque (typically 20-25 lb-ft).
Replace the oil filter with a new one, ensuring the rubber O-ring is lubricated and properly seated.
