why is my Honda Civic 9th Generation (2012-2015) using too much oil?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and allow the engine to cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Repair Oil Leaks

• Tools Required: Socket set, torque wrench, oil catch pan
• Inspect the oil pan, valve cover gasket, and oil filter for leaks.
• Tighten any loose bolts or replace gaskets as needed.
• Use RTV sealant where applicable to ensure a proper seal.

3. Replace PCV Valve

• Tools Required: Pliers, socket set
• Locate the PCV valve (usually attached to the valve cover).
• Disconnect the hose connected to the PCV valve.
• Remove the old valve from its socket and replace it with a new one.
• Reattach the hose securely.

4. Perform Engine Compression Test

• Tools Required: Compression tester
• Remove the spark plugs for easy access.
• Insert the compression tester into each cylinder and crank the engine.
• Record the compression readings and compare them to manufacturer specifications.
• If readings are low, further investigation of piston rings and cylinder walls may be necessary.

5. Replace Piston Rings (if necessary)

• Tools Required: Engine hoist, socket set, torque wrench
• Remove the engine from the vehicle if required.
• Disassemble the engine to access the piston rings.
• Replace the old piston rings with new ones.
• Reassemble the engine, ensuring proper torque on all bolts.
