how to deal with excessive oil consumption in Honda Accord 9th Generation (2013-2017)

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and ensure the engine is cool.
• Disconnect the negative battery terminal for safety.

Tools Required:

• Socket set
• Torque wrench
• Compression tester
• Leak-down tester
• PCV valve wrench

2. Inspect and Repair Leaks

• Sub-steps:
  • Clean the engine area with a degreaser to identify leaks more easily.
  • Inspect valve cover gaskets, oil pan seals, and front and rear crankshaft seals for oil seepage.
  • Replace any faulty gaskets or seals using the appropriate torque specifications (typically around 8-10 ft-lbs for most gaskets).

3. Replace PCV Valve

• Sub-steps:
  • Locate the PCV valve (typically on the valve cover).
  • Remove the PCV valve using a wrench.
  • Install the new PCV valve and ensure it is seated properly.

4. Address Engine Wear

• Sub-steps:
  • If compression or leak-down tests indicate significant wear, consider replacing piston rings or valve seals.
  • Remove the engine head (requires removing the intake and exhaust manifolds) to access valve seals.
  • Replace valve seals and reinstall the head using the manufacturer’s torque specifications (usually 30-45 ft-lbs).
  • If piston rings are replaced, the engine may require a complete overhaul.

5. Monitor Oil Usage

• Sub-steps:
  • After repairs, monitor oil consumption over the next few weeks to ensure the issue is resolved.
  • Adjust oil change intervals based on usage and manufacturer recommendations.
