Solution

1. Preparation

Gather tools: socket set, torque wrench, oil catch pan, and replacement fluids.
Ensure the engine is cool and disconnect the battery.

2. Address External Leaks

Locate leaks: Inspect the oil pan and valve cover for any cracks or loose bolts.
Repair as necessary: Replace gaskets or tighten bolts to eliminate leaks.
Tools Required: Torque wrench for proper reassembly.

3. Replace PCV Valve

Remove the old PCV valve: Locate the valve, disconnect the hose, and pull it out.
Install the new PCV valve: Ensure it is seated properly and reconnect the hose.
Tools Required: Pliers to disconnect the hose.

4. Engine Internal Inspection

Perform compression and leak-down tests: Follow manufacturer specifications for testing procedures.
Evaluate results: If compression is low or leaks are present, further disassembly may be required, such as removing the cylinder head.

5. Oil Change

Drain old oil: Remove the oil drain plug and allow the oil to fully drain into the catch pan.
Replace oil filter: Remove the old filter and install a new one, lubricating the gasket with new oil.
Refill with new oil: Add the correct type and amount of engine oil as specified in the owner’s manual.
