2. Identify the Leak Source

Oil Filter Check:
- Remove the oil filter using the appropriate socket or filter wrench.
- Inspect the rubber O-ring on the filter for damage.
- Replace the oil filter if it shows signs of leakage.
Inspect the Front Crankshaft Seal:
- Remove any components obstructing access to the crankshaft seal (e.g., belts, pulleys).
- Use a seal puller to carefully remove the old crankshaft seal if found to be leaking.
- Clean the sealing surface and install a new crankshaft seal with proper orientation.

3. Replace Valve Cover Gasket

Remove Valve Cover:
- Detach necessary components such as ignition coils and wiring harnesses.
- Unscrew the valve cover bolts using a socket set. Keep track of bolt locations.
Install New Gasket:
- Clean the valve cover mating surface thoroughly.
- Place the new gasket on the valve cover, ensuring proper alignment.
- Reinstall the valve cover and torque the bolts to the manufacturer's specifications (typically 7-9 lb-ft).

4. Refill Engine Oil

Refill engine oil to the recommended level using the correct type of oil specified in the owner's manual.
Start the engine and let it idle for a few minutes while checking for leaks.
