Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool and parked on a level surface.
Disconnect the battery to prevent any electrical issues while working.

2. Drain Engine Oil

Place an oil catch pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the oil to fully drain.
Reinstall the drain plug and torque it to the manufacturer's specifications (usually around 25 Nm).

3. Replace Gasket/Seal

Front Crankshaft Seal:
- Remove the serpentine belt and any components obstructing access to the crankshaft pulley.
- Remove the crankshaft pulley using a puller tool.
- Pry out the old front seal and clean the sealing surface.
- Install the new front crankshaft seal carefully to avoid damage.
- Reassemble the crankshaft pulley and torque to specifications.
Timing Cover Gasket (if applicable):
- Remove the necessary components to access the timing cover (timing belt or chain, accessory belts).
- Remove the timing cover bolts and gently pry off the timing cover.
- Clean the mating surfaces and replace the old gasket with a new one.
- Reattach the timing cover and torque the bolts to the specified value.

4. Refill Engine Oil

Fill the engine with new oil through the oil filler cap, using the correct type and amount as specified in the owner's manual.
Start the engine and allow it to run for a few minutes, checking for leaks around the repaired areas.

5. Final Assembly

Reattach any components that were removed during the repair.
Reconnect the battery.
