Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, torque wrench, oil catch pan, new oil filter, engine oil, and UV dye.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Oil Level Check and Drain

Open the hood and remove the dipstick to check the oil level.
If the level is low, prepare to drain the existing oil:
- Place an oil catch pan under the oil pan.
- Remove the drain plug using a socket wrench and allow the oil to fully drain.

3. Inspect and Replace Oil Filter

Locate the oil filter and use an oil filter wrench to remove it.
Apply a light coat of new oil to the rubber gasket of the new oil filter.
Install the new oil filter and tighten according to manufacturer specifications.

4. Inspect and Replace Seals if Necessary

If the timing cover or front crankshaft seal is leaking:
- Remove the timing cover by unscrewing the bolts with a socket set.
- Carefully remove the old seal and clean the mating surfaces.
- Install the new seal, ensuring it is seated properly, and reattach the timing cover, tightening to specified torque.

5. Refill Engine Oil

Replace the drain plug and tighten it securely.
Refill the engine with the appropriate type and amount of engine oil as specified in the owner's manual.

6. Final Checks

Start the engine and let it run for a few minutes while checking for leaks around the oil filter and seals.
Monitor the oil pressure gauge and ensure it operates within normal parameters.
