Solution

1. Preparation

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

2. Address Oil Leaks

Locate the source of the leak:
- Inspect the valve cover gasket, oil filter, and oil drain plug.
- Clean any residual oil with a degreaser to pinpoint the source.
Replace the valve cover gasket (if leaking):
- Remove the engine cover if present.
- Unscrew the bolts securing the valve cover using a socket set.
- Carefully lift the valve cover off and remove the old gasket.
- Clean the mating surfaces on both the valve cover and the engine.
- Place a new gasket on the valve cover and reattach it, tightening bolts to the manufacturer’s torque specifications.
Replace the oil filter (if necessary):
- Use an oil filter wrench to remove the old filter.
- Apply a small amount of new oil to the rubber gasket of the new filter.
- Install the new filter, tightening it according to the manufacturer’s specifications.
Check the oil drain plug:
- Tighten the oil drain plug if it is loose or replace the washer if it is worn.

3. Clean Up

After repairs, clean any spilled oil from the engine bay and surrounding areas to prevent further odors.
Refill the engine oil to the correct level if necessary.
