Solution

1. Preparation

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

2. Clean the Engine Bay

Use a degreaser to clean any oily residue from the engine area.
Rinse with water and allow the engine to dry completely.

3. Inspect and Replace Gaskets and Seals

Tools Required: Socket set, torque wrench, gasket scraper
Remove components obstructing access to the valve cover and oil pan.
Inspect the valve cover gasket, oil pan gasket, and any other seals for wear or damage.
Replace any damaged gaskets with new ones, ensuring they are seated properly.
Torque the bolts to manufacturer specifications.

4. Replace the Oil Filter and Oil

Tools Required: Oil filter wrench, oil catch pan
Remove the old oil filter using the oil filter wrench.
Install the new oil filter, applying a small amount of oil to the rubber gasket beforehand.
Drain the old engine oil completely and replace it with new oil as specified in the owner’s manual (check oil type and capacity).
Start the engine and let it run for a few minutes, then check for leaks.

5. Test Drive

After repairs, take the vehicle for a short test drive to ensure the smell is gone and there are no leaks.
