Solution

1. Preparation

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

2. Inspect and Repair Oil Leaks

Inspect Engine Bay:
- Look for any obvious leaks or oil residue around the engine components.
- Use a flashlight to get a better view of hard-to-see areas.
Check Oil Filter:
- Locate the oil filter and inspect it for leaks.
- If leaking, replace it with a new filter. Use an oil filter wrench to remove the old one, applying oil to the rubber gasket of the new filter before installation.
Examine Valve Cover Gasket:
- Remove the screws/bolts securing the valve cover.
- Lift off the valve cover and check the gasket for cracks or wear.
- If damaged, replace the gasket with a new one and reassemble the valve cover, tightening bolts to manufacturer specifications.
Inspect Oil Pan:
- If the oil pan is leaking, drain the oil and remove the oil pan.
- Clean the sealing surfaces and install a new gasket or RTV sealant as required. Reinstall the pan and torque bolts to specifications.

3. Clean Up

Clean any spilled oil from the engine bay and undercarriage using degreaser and rags.
Refill the engine oil to the correct level and replace the oil cap.
