Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, rags, OBD-II scanner.
Safety Warnings: Disconnect the battery before starting any work. Allow the engine to cool before beginning repairs.

2. Identify and Repair Oil Leaks

Clean the Engine: Use a degreaser to clean the engine compartment to identify leaks more easily.
Inspect Gaskets and Seals: Check the valve cover gasket, oil pan gasket, and front and rear main seals for visible wear or damage.
- If damaged, remove the affected component to replace the gasket or seal.
Replace Gaskets/Seals:
- Remove the old gasket/seal material completely.
- Install the new gasket/seal, ensuring a proper fit.
- Torque bolts to the manufacturer's specifications.
Check Oil Filter: Ensure the oil filter is properly tightened and not leaking.

3. Engine Oil Change (if required)

Drain Old Oil: Remove the oil drain plug and allow the old oil to completely drain into the catch pan.
Replace Oil Filter: Install a new oil filter, applying a thin layer of oil to the rubber seal before tightening.
Add New Oil: Fill the engine with the manufacturer-specified type and amount of oil.
Check for Leaks: Start the engine and check for any leaks around the repaired areas.
