Solution

1. Preparation

Gather tools and parts.
Allow the engine to cool down.
Disconnect the battery to prevent accidental short circuits.

2. Inspect and Repair Leaks

Tools Required: Socket set, torque wrench, oil drain pan.
Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Clean the area of suspected leaks thoroughly.
3. Tighten any loose bolts on the oil pan or valve covers to manufacturer specifications.
4. Replace any worn gaskets or seals that are leaking.
5. Refill engine oil to the correct level after repairs.

3. Replace Worn Components

Tools Required: Socket set, torque wrench, oil filter wrench.
Sub-steps:
1. If the compression test indicates low compression, remove the cylinder head.
2. Inspect piston rings and replace if they are worn or damaged.
3. Replace valve seals if signs of oil leakage into the combustion chamber are present.
4. Reassemble the engine components following manufacturer specifications for torque.

4. Check and Repair PCV System

Tools Required: Screwdriver, vacuum gauge.
Sub-steps:
1. Locate the PCV valve and check for blockage or damage.
2. Clean or replace the PCV valve as necessary.
3. Inspect hoses for cracks or obstructions, replacing any faulty components.
