Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is on a flat surface and the engine is cool.
Tools Required: Oil catch pan, socket set, torque wrench, OBD-II scanner, cleaning rags.

2. Address Oil Leaks

Identify Leak Source: From the diagnostic steps, pinpoint where the oil is leaking from (e.g., gasket, seal, filter).
Replace Gaskets/Seals:
- Remove the old gasket or seal using a scraper.
- Clean the mating surfaces with a rag.
- Apply a new gasket or sealant according to manufacturer specifications.
Replace Oil Filter (if applicable):
- Use an oil catch pan to catch any residual oil.
- Remove the old oil filter using an appropriate tool.
- Apply a thin film of new oil to the gasket of the new filter.
- Install the new filter hand-tight, then use a wrench for an additional 3/4 turn.

3. Refill Engine Oil

Drain Old Oil: If the oil level is low or dirty, drain the old oil by removing the drain plug (ensure the oil catch pan is in position).
Replace Drain Plug: Reinstall the drain plug and torque it to the manufacturer’s specifications.
Add New Oil: Pour in the appropriate type and amount of new oil as specified in the owner's manual.

4. Final Checks

Start the engine and let it idle for a few minutes while checking for leaks.
Make sure the oil pressure light is off and monitor oil levels after a short drive.
