Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, oil filter wrench, shop towels, engine oil, and new gaskets if needed.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Oil Leaks

Check Oil Filter:
- Remove the oil filter using an oil filter wrench.
- Inspect the old filter's rubber seal for damage; replace if necessary.
- Install a new oil filter, ensuring the rubber seal is lubricated with fresh oil.
Inspect and Replace Gaskets:
- Valve Cover Gasket:
  - Remove any engine covers blocking access to the valve cover.
  - Unbolt the valve cover using a socket set, gently lifting it off.
  - Remove the old gasket material and clean the mating surfaces.
  - Install a new valve cover gasket, ensuring it is positioned correctly, then reattach the valve cover and torque it to manufacturer specifications.
- Oil Pan Gasket:
  - Drain the engine oil and remove the oil pan bolts.
  - Carefully detach the oil pan, clean the old gasket material from both the pan and the engine block.
  - Install the new gasket and reattach the oil pan, torquing the bolts to the specified value.

3. Refill Engine Oil

Refill the engine with the appropriate oil type and quantity as specified in the owner’s manual.
Start the engine and allow it to run for a few minutes while checking for leaks.
