Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid electrical issues during the repair.

2. Locate the Source of the Leak

Tools Required: Flashlight
Thoroughly clean the area around the suspected leak with an engine cleaner to remove oil residue.
Use a flashlight to inspect the cleaned area for fresh oil seeping out.

3. Replace the Oil Filter

Tools Required: Oil filter wrench, oil catch pan
Remove the old oil filter using the oil filter wrench, ensuring to catch any residual oil in the oil catch pan.
Apply a thin layer of new oil to the rubber gasket on the new oil filter.
Install the new oil filter by hand until snug, then tighten it an additional 3/4 turn.

4. Repair or Replace Gaskets

Tools Required: Socket set, torque wrench, gasket scraper
If the valve cover gasket or oil pan gasket is leaking, remove the bolts securing the valve cover or oil pan.
Carefully lift off the cover or pan and remove the old gasket.
Clean the mating surfaces with a gasket scraper and ensure no old material remains.
Install a new gasket, ensuring it is properly aligned, and reattach the cover or pan, tightening bolts in a crisscross pattern to the manufacturer’s specified torque.

5. Fill Engine Oil

Tools Required: Funnel
After repairs are completed, refill the engine with the appropriate type and amount of oil using a funnel.
