Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical hazards.

2. Inspect and Repair Oil Leaks

Tools Required: Socket set, torque wrench, oil catch pan, rags
Sub-steps:
1. Locate leaks: Clean the engine bay and run the engine to identify the source of leaks.
2. Replace gaskets/seals: If leaks are found, replace any worn or damaged gaskets (e.g., valve cover gasket, oil pan gasket).
3. Torque specifications: Reinstall components to manufacturer torque specifications to prevent future leaks.

3. Address PCV Issues

Tools Required: Pliers, screwdriver
Sub-steps:
1. Remove the PCV valve: Disconnect hoses from the PCV valve and remove it.
2. Inspect for blockages: Clean or replace the PCV valve if it is clogged or malfunctioning.
3. Reinstall the PCV system: Reattach the hoses securely ensuring no leaks.

4. Perform Compression Test

Tools Required: Compression tester
Sub-steps:
1. Remove spark plugs: Disconnect and remove the spark plugs from each cylinder.
2. Attach compression tester: Insert the compression tester into the spark plug hole of each cylinder.
3. Crank the engine: Record the compression readings and compare them to manufacturer specifications. If low, consider replacing piston rings.

5. Change Oil and Filter

Tools Required: Oil filter wrench, oil catch pan, socket set
Sub-steps:
1. Drain old oil: Remove the oil drain plug and allow oil to fully drain into the catch pan.
2. Replace oil filter: Use an oil filter wrench to remove the old filter and install a new one.
3. Add new oil: Reinstall the drain plug and add the correct type and amount of oil as specified in the owner’s manual.
