Solution

1. Preparation

• Gather tools and parts for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical issues while working.

2. Inspect and Repair PCV System

• Sub-steps:
  • Locate the PCV valve and hoses.
  • Remove the PCV valve and inspect for blockage or damage.
  • If blocked, clean with carburetor cleaner; if damaged, replace with a new PCV valve.
  • Reconnect the hoses ensuring they are securely fastened.

3. Replace Worn Piston Rings (if necessary)

• Sub-steps:
  • Remove the engine cylinder head by following the manufacturer's service manual for specific procedures.
  • Remove the pistons from the engine block. This may require removing the oil pan and connecting rods.
  • Inspect and measure the piston rings using a feeler gauge for wear. Replace if out of specification.
  • Install new piston rings and reassemble the engine components in the reverse order of disassembly.

4. Add Engine Oil Supplement (if applicable)

• Sub-steps:
  • If the oil burning is minor, consider adding an engine oil supplement designed to reduce oil consumption.
  • Follow the manufacturer's instructions for the correct application.
