Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool down before starting work.

2. Address Oil Leaks

Tools Required: Socket set, torque wrench, oil catch pan.
Sub-steps:
1. Identify and tighten any loose bolts on the oil pan and valve cover.
2. Replace any damaged gaskets or seals that are leaking oil.
3. Use a cleaning solution to clean the area around leaks before applying new gaskets to ensure a proper seal.

3. PCV System Repair

Tools Required: Screwdriver set, replacement PCV valve.
Sub-steps:
1. Locate the PCV valve on the engine.
2. Remove the old PCV valve and inspect the hoses for cracks or blockages.
3. Install the new PCV valve and replace any damaged hoses.
4. Ensure all connections are secure and free of leaks.

4. Compression Test

Tools Required: Compression tester.
Sub-steps:
1. Remove spark plugs to prevent engine damage during testing.
2. Insert the compression tester into the spark plug hole of each cylinder.
3. Crank the engine and take note of the pressure readings.
4. Compare readings across all cylinders; if any are significantly lower, it may indicate worn piston rings or cylinder walls.
