Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Address Oil Leaks

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the undercarriage cover if equipped.
3. Inspect the valve cover gasket and oil pan for leaks.
4. Replace the valve cover gasket if it shows signs of wear.
  - Tools: Socket set, gasket scraper, torque wrench.
  - Apply manufacturer-recommended torque settings when re-installing.

3. Check and Replace PCV Valve

Sub-steps:
1. Locate the PCV valve (usually on the valve cover).
2. Remove the PCV valve and inspect for blockage or damage.
3. Replace with a new PCV valve if it is clogged or faulty.
  - Tools: Pliers, socket set.

4. Perform Compression Test

Sub-steps:
1. Remove spark plugs from the engine.
2. Insert a compression tester into the spark plug hole.
3. Crank the engine and record the compression readings.
4. Compare the readings to manufacturer specifications.
5. If readings are low, consider further inspection or rebuilding the engine.

5. Replace Engine Oil and Filter

Sub-steps:
1. Drain the old engine oil and replace the oil filter.
