Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace PCV Valve

Locate the PCV valve on the valve cover.
Remove the hose connected to the PCV valve.
Unclip or unscrew the PCV valve from its housing.
Install the new PCV valve by securing it in place.
Reattach the hose to the new PCV valve.

3. Address Oil Leaks

Identify the source of any oil leaks found during diagnostics.
Replace any damaged gaskets, seals, or components as necessary.
Clean the area around the leak to prevent contamination.
Refill the engine with the appropriate type and amount of oil.

4. Engine Rebuild (if necessary)

If compression tests indicate significant wear, prepare for an engine rebuild.
Remove the engine from the vehicle using a hoist.
Disassemble the engine and inspect components such as piston rings, cylinder walls, and valves.
Replace worn components as needed and follow manufacturer specifications for reassembly.
Reinstall the engine and reconnect all components.
