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 to prevent any electrical issues during the repair.

2. Identify and Fix Oil Leaks

Inspect Valve Cover Gasket:
- Remove any components obstructing access to the valve cover.
- Unbolt the valve cover using a socket set.
- Remove the old gasket and clean the surfaces with a gasket scraper.
- Install a new valve cover gasket and reassemble the valve cover, tightening bolts to manufacturer's specifications (typically 10-15 Nm).
Check Oil Filter:
- Using an oil filter wrench, remove the old oil filter.
- Apply a thin layer of oil on the rubber gasket of the new filter before installation.
- Install the new oil filter, hand-tightening it according to manufacturer guidelines.

3. Clean Up and Refill

Clean any spilled oil from the engine and surrounding areas using a degreaser.
Refill the engine oil to the recommended level using the correct oil specification (typically 5W-30 or as per manufacturer recommendations).
Reconnect the battery.
