Disconnect the battery to avoid electrical issues during inspection.

2. Locate the Source of the Leak

Sub-steps:
1. Remove any engine covers if necessary using a socket set.
2. Clean the engine bay with a degreaser to identify the leak source more easily.
3. Start the engine and visually inspect for oil seeping from gaskets, seals, and the oil filter.

3. Repair the Leak

Sub-steps:
1. If a gasket or seal is leaking, remove the affected component (e.g., valve cover or oil pan) using the appropriate tools.
2. Clean the mating surfaces thoroughly with a scraper and solvent.
3. Install a new gasket or seal, ensuring proper alignment.
4. Reinstall the component and torque to manufacturer's specifications.

4. Replace the Oil Filter (if applicable)

Sub-steps:
1. Use an oil filter wrench to remove the old oil filter.
2. Apply a small amount of fresh oil to the rubber gasket of the new filter.
3. Install the new filter by hand until snug, then tighten an additional 3/4 turn.
