Safety Warnings: Disconnect the battery before working on electrical systems; allow the engine to cool before opening any components.

2. Address Oil Leaks

2.1 Inspect and Replace Gaskets

Valve Cover Gasket:
- Remove the engine cover if equipped.
- Disconnect any electrical connectors and hoses obstructing access to the valve cover.
- Remove the valve cover bolts using a socket set (torque specs: 7.2-9.3 ft-lbs).
- Carefully lift the valve cover off and inspect the gasket; replace if damaged.
- Clean the mating surfaces and install a new gasket. Reinstall the valve cover and torque bolts to specifications.

2.2 Check Oil Filter

Remove the oil filter using an oil filter wrench.
Inspect the old filter for any signs of damage or leaks.
Apply a small amount of new oil to the rubber gasket of the new filter. Install the new filter and tighten it according to manufacturer specifications.

2.3 Clean Up Any Spills

Use rags to clean any spilled oil from the engine and surrounding areas.
If necessary, use an oil catch pan to collect any dripping oil.
