Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather tools and materials (see Tools Required section).
Allow the engine to cool before starting work.

2. Inspect and Address Oil Leaks

Sub-step 1: Locate the source of the oil leak by cleaning the engine bay with a degreaser.
Sub-step 2: Use a flashlight to examine the engine components for oil residue.
Sub-step 3: Tighten any loose bolts on the valve cover or oil filter if applicable.
Sub-step 4: Replace any damaged gaskets or seals (e.g., valve cover gasket, oil pan gasket) as necessary.

3. Replace Oil Filter and Oil

Sub-step 1: Remove the old oil filter using an oil filter wrench.
Sub-step 2: Install a new oil filter, ensuring the rubber O-ring is lubricated and seated properly.
Sub-step 3: Drain old oil using a drain pan, then replace with fresh oil of the manufacturer's recommended type and quantity.
Sub-step 4: Start the engine and let it run for a few minutes while checking for leaks.

4. Inspect and Clean PCV System

Sub-step 1: Locate the PCV valve, usually on the valve cover or intake manifold.
Sub-step 2: Remove the PCV valve and inspect for blockages; clean or replace as needed.
Sub-step 3: Reinstall the PCV valve securely.
