Solution

1. Preparation

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

2. Change Engine Oil and Filter

Drain Oil
- Place the oil catch pan under the oil pan.
- Remove the drain plug with a socket wrench and allow the old oil to fully drain.
- Replace the drain plug and torque it to the manufacturer’s specifications (typically around 30 Nm).
Remove Oil Filter
- Use the oil filter wrench to unscrew the old oil filter.
- Ensure the rubber O-ring from the old filter is removed from the engine.
Install New Oil Filter
- Apply a small amount of new engine oil to the O-ring on the new filter.
- Screw in the new oil filter hand-tight, and then tighten it according to specifications (usually 3/4 turn after contact).
Add New Engine Oil
- Remove the oil filler cap and use a funnel to add the recommended type and amount of new engine oil (refer to the owner’s manual).
- Replace the oil filler cap.

3. Address Potential Internal Issues

Inspect PCV System
- Remove and clean the PCV valve if clogged, or replace it if defective.
- Ensure all hoses are connected properly and free of cracks.
Repair or Replace Components if Necessary
- If compression tests indicate cylinder wear, consider a top-end rebuild or replacing piston rings.
- Inspect and replace any faulty gaskets or seals that may contribute to oil burning.
