Solution

1. Preparation

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

2. Inspect and Replace Gaskets and Seals

Remove Engine Covers: Use a socket set to remove any engine covers obstructing access to the valve cover or oil pan.
Inspect Gaskets: Check the valve cover gasket and oil pan gasket for signs of wear or leaks.
Replace Gaskets: If damaged, clean the surfaces with a gasket scraper and install new gaskets, applying the manufacturer’s recommended torque specifications.

3. Replace Worn Components

Piston Ring Replacement: If the compression test indicates issues, consider replacing worn piston rings.
- Remove the cylinder head and piston assembly.
- Replace the piston rings and reassemble, ensuring proper torque values are met.
Inspect and Replace PCV Valve: If malfunctioning, remove the PCV valve from its housing and replace it with a new one.

4. Change Oil and Filter

Drain Old Oil: Remove the oil drain plug and drain the old oil into a suitable container.
Replace Oil Filter: Use an oil filter wrench to remove the old filter. Install a new oil filter, lubricating the rubber seal with new oil.
Add New Oil: Reinstall the drain plug and fill the engine with the recommended oil type and quantity.
