my Skoda Octavia NFL (2020-Present) is consuming too much oil what can I do

Solution

1. Preparation

• Gather tools and materials: OBD-II scanner, compression tester, leak-down tester, socket set, torque wrench, new oil filter, and the correct grade of engine oil.
• Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Replace Gaskets

• Step 1: Remove the engine cover (if applicable) using a socket set.
• Step 2: Inspect the valve cover gasket and oil pan gasket for signs of wear or leakage.
• Step 3: If damaged, replace the gaskets:
  • Remove the valve cover or oil pan by unscrewing the bolts.
  • Clean the mounting surfaces thoroughly.
  • Apply the new gasket and torque the bolts to the manufacturer’s specifications (typically found in service manual).

3. Address PCV System

• Step 1: Locate the PCV valve; it is usually connected to the intake manifold.
• Step 2: Remove the PCV valve and inspect for clogs or damage.
• Step 3: Replace with a new PCV valve if necessary, ensuring it's securely fitted.

4. Perform Compression and Leak-Down Tests

• Step 1: Remove spark plugs to access the cylinders.
• Step 2: Insert the compression tester into the spark plug hole and crank the engine to read the pressure.
• Step 3: For leak-down testing, follow the manufacturer's instructions for setup and measurements.
• Step 4: If compression is low or leakage is evident, consider replacing piston rings or addressing cylinder wear.

5. Add Oil and Monitor

• Step 1: Refill the engine with the recommended grade of oil.
• Step 2: Monitor oil levels regularly and check for any new symptoms.
