Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the engine is cool and disconnect the battery.
Place the vehicle on a level surface and lift it using a jack and jack stands for better access.

2. Locate the Leak Source

Clean the engine area with a degreaser to eliminate old oil residue.
Start the engine and observe the front of the engine for fresh oil leaks.
Identify the exact source of the leak (e.g., front crankshaft seal, oil filter, or gaskets).

3. Replace Front Crankshaft Seal (if applicable)

Remove the serpentine belt using a wrench to relieve tension.
Remove the crankshaft pulley using a socket set and torque wrench, noting the torque specifications for reinstallation.
Pull out the old crankshaft seal using a seal puller.
Lubricate the new seal with engine oil and install it carefully, ensuring not to damage it.
Reinstall the crankshaft pulley and serpentine belt, tightening to the specified torque.

4. Replace Valve Cover Gasket (if applicable)

Remove any components obstructing access to the valve cover (e.g., ignition coils).
Unbolt the valve cover using a socket set and carefully lift it off.
Clean the mating surfaces thoroughly with a gasket scraper.
Install a new valve cover gasket, ensuring it is seated properly.
Reinstall the valve cover and torque bolts to manufacturer specifications.

5. Inspect and Replace Oil Filter (if necessary)

Remove the old oil filter with an oil filter wrench.
Lubricate the rubber O-ring on the new oil filter with fresh oil.
Install the new oil filter, tightening it by hand plus a quarter turn.

6. Refill Engine Oil

After all repairs, refill the engine with the correct type and amount of oil as specified in the owner's manual.
Start the engine and let it run for a few minutes while checking for leaks.
