5. Apply New Gasket Sealant:
- Apply a thin and uniform coat of gasket sealant to the mating surface of the oil pan. Make sure to follow the manufacturer's instructions for the sealant you are using.
- Let the sealant cure according to the specified drying time.
6. Reinstall the Oil Pan:

9. Test for Leaks:
- Start the engine and let it run for a few minutes.
- Check for any oil leaks around the oil pan and oil filter.
- If there are no leaks, turn off the engine and allow it to cool down.
10. Double-Check:
- Recheck the oil level and ensure it is between the "Full" and "Add" marks on the oil dipstick.
