Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to prevent electrical issues during the repair.

2. Identify and Clean the Affected Area

Use a degreaser to clean the area around the suspected leak to remove old oil.
Dry the surface thoroughly to improve visibility of the leak source.

3. Replace the Oil Filter (if leaking)

Tools Required: Oil filter wrench, oil catch pan.
Unscrew the oil filter using an oil filter wrench.
Prepare the new oil filter by applying a thin layer of oil to the rubber gasket.
Install the new oil filter by hand, tightening it according to the manufacturer’s specifications (usually hand-tight + 3/4 turn).

4. Replace Gaskets (if applicable)

Tools Required: Socket set, torque wrench, gasket scraper.
Remove the components covering the valve cover or oil pan as needed (e.g., intake manifold).
Remove the old gasket using a gasket scraper carefully to avoid damaging surfaces.
Clean the mating surfaces thoroughly.
Apply a new gasket or gasket maker, following manufacturer specifications for application.
Reinstall the valve cover or oil pan, torquing bolts to the specified torque value.

5. Refill Engine Oil

Use a funnel to pour the appropriate type and amount of engine oil as per manufacturer's recommendations.
Run the engine for a few minutes and check for leaks around the repaired areas.

6. Reconnect Battery

Reconnect the battery terminal securely.
