Solution

1. Preparation

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

2. Inspect and Repair Oil Leaks

Tools Required: Socket set, torque wrench, oil catch pan
Locate and repair any visible oil leaks by tightening loose components or replacing gaskets and seals as necessary.
Use a clean cloth to wipe down areas around suspected leaks to observe any oil re-emergence after repairs.

3. Replace PCV Valve (if necessary)

Tools Required: Pliers, socket set
Locate the PCV valve and disconnect the hose.
Remove the old PCV valve and replace it with a new one.
Reconnect the hose and ensure it is secure.

4. Perform Compression Test

Tools Required: Compression tester
Remove the spark plugs for better access.
Insert the compression tester into each cylinder, cranking the engine a few times to obtain readings.
Compare results to manufacturer specifications; if readings are low, further engine inspection is needed.

5. Replace Spark Plugs (if oil fouled)

Tools Required: Socket set, torque wrench
Remove the oil-fouled spark plugs and inspect for damage.
Replace with new spark plugs that meet manufacturer specifications, ensuring correct torque upon installation.
