Solution

1. Preparation

Tools Required: Jack and jack stands, oil catch pan, socket set, torque wrench, UV dye kit, black light.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical issues during repairs.

2. Check and Replace Oil Filter

Locate the oil filter and inspect it for leaks.
If leaking, use an oil filter wrench to remove the old filter.
Apply a thin layer of new oil on the rubber O-ring of the new filter.
Install the new oil filter by hand, then tighten according to manufacturer specifications (usually around 18-25 ft-lbs).

3. Inspect and Replace Oil Drain Plug

Place an oil catch pan under the oil drain plug.
Using the appropriate socket, remove the drain plug and allow the oil to fully drain.
Inspect the drain plug for wear and replace the washer if necessary.
Reinstall the drain plug and torque to manufacturer specifications (usually around 20-30 ft-lbs).

4. Inspect and Replace Gaskets

If leaks are found around gaskets, remove affected components (e.g., valve covers, oil pan).
Clean surfaces where gaskets will be installed.
Replace old gaskets with new ones, ensuring proper alignment.
Reinstall components and torque bolts to manufacturer specifications.

5. Final Check

Refill the engine with the appropriate type and amount of oil.
Start the engine and let it run for a few minutes while checking for leaks.
Monitor the oil level and top off if necessary.
