Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, torque wrench, oil filter wrench, compression tester, multimeter, and rags.
Safety Warning: Disconnect the battery before performing any electrical work.

2. Address Oil Leaks

Identify Source: Locate the exact source of oil leaks by cleaning the affected area and monitoring for fresh oil.
Replace Gaskets/Seals: Replace any worn or damaged gaskets and seals. This may include valve cover gaskets, oil pan gasket, or rear main seal.
- Tools Required: Socket set, torque wrench.
- Sub-steps:
  1. Remove any components obstructing access to the gasket/seal.
  2. Remove old gasket material from surfaces.
  3. Apply new gasket or sealant as per manufacturer specifications.
  4. Reinstall components and torque to factory specifications.

3. Replace PCV Valve

Remove Old PCV Valve: Disconnect the hose and pull out the existing PCV valve.
Install New PCV Valve: Insert a new PCV valve, ensuring a snug fit.
- Tools Required: Pliers (if needed for hose clamps).

4. Compression Test (if necessary)

Conduct Compression Test: Follow the compression tester instructions to measure cylinder pressure.
- If readings are low (below manufacturer specifications), further investigation may be needed for piston rings or cylinder wall wear.

5. Regular Maintenance

Change Oil and Filter: If oil consumption is excessive, perform an oil change with the correct oil type and new filter.
- Tools Required: Oil filter wrench, socket set.
- Sub-steps:
  1. Drain engine oil and replace the oil filter.
  2. Refill with manufacturer-recommended oil type and quantity.
