Solution

1. Preparation

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

2. Locate and Address the Oil Leak

A. If the leak is from the oil filter:

Use an oil filter wrench to remove the old oil filter.
Clean the mounting surface on the engine.
Apply fresh oil to the rubber gasket of the new filter.
Install the new oil filter by hand-tightening it, then use the wrench for an additional 3/4 turn.

B. If the leak is from the oil drain plug:

Use a socket wrench to remove the oil drain plug.
Inspect the drain plug and washer for damage; replace if necessary.
Clean the threads and re-install the drain plug, tightening to the manufacturer’s torque specification (typically around 20 lb-ft).

C. If the leak is from gaskets or seals:

Remove any components obstructing access to the valve cover or oil pan.
Remove the old gasket or seal material carefully.
Clean the mating surfaces thoroughly.
Apply a thin bead of gasket maker if required, or place a new gasket.
Reassemble components, tightening bolts to the specified torque.
