Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Inspect and Repair Oil Leaks

Tools Required: Socket set, wrench set, oil catch pan, cleaning rags
Identify the source of the leak (e.g., valve cover gasket, oil pan gasket).
Remove any components blocking access to the leaking area.
Clean the area thoroughly with a degreaser.
Replace the damaged gasket or seal with a new one, ensuring proper fitment.
Reassemble any removed components and refill oil if necessary.

3. Change Engine Oil and Filter

Tools Required: Wrench set, oil filter wrench, oil catch pan, funnel
Remove the oil drain plug and allow the old oil to drain completely into the catch pan.
Replace the oil filter using an oil filter wrench.
Install the drain plug back, ensuring it is torqued to the manufacturer's specifications.
Refill with new oil of the recommended type and capacity as specified in the owner's manual.

4. Inspect Engine Components

Check the exhaust system for signs of oil burning, especially at joints or seals.
Inspect the PCV (Positive Crankcase Ventilation) system for blockages or malfunctions.
Clear any obstructions in the air intake system that could lead to poor engine performance.
