Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Address External Oil Leaks

Tools Required: Socket set, torque wrench, oil catch pan
Inspect for leaks around the oil filter and oil pan.
If leaks are found, replace the oil filter or reseal the oil pan using a suitable gasket maker.
Refill any lost oil before testing the vehicle.

3. Replace PCV Valve

Tools Required: Pliers, socket set
Locate the PCV valve; remove the hose connected to it.
Remove the old PCV valve and install the new one.
Secure the hose back onto the valve.

4. Perform Engine Repair (if necessary)

Tools Required: Socket set, torque wrench, engine oil
If compression or leak-down tests indicate worn piston rings or valve seals, plan for a more extensive engine rebuild or repair.
This may involve removing the cylinder head to access and replace worn components.
Reassemble the engine, ensuring all bolts are torqued to manufacturer specifications.
