Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, compression tester, and shop towels.
Disconnect the negative terminal of the battery.
Allow the engine to cool before starting any work.

2. Inspect and Replace PCV Valve

Locate the PCV valve on the engine.
Remove the PCV valve using a socket set.
Inspect the valve for clogs or damage.
If damaged, replace it with a new PCV valve.
Reinstall the valve and ensure it is seated properly.

3. Perform an Oil Change

Drain the engine oil using a drain pan.
Replace the oil filter with a new one.
Refill the engine with the manufacturer-recommended oil type and quantity.

4. Repair or Replace Faulty Components

If Compression Test Indicates Issues:
- Remove the valve cover to inspect the valve seals and springs.
- Replace seals if they show signs of wear.
- Reassemble the valve cover and torque to manufacturer specifications.
If Fuel System Issues are Detected:
- Test fuel injectors for leaks or malfunctions.
- Replace any faulty injectors as necessary.

5. Check for Coolant Leaks

Inspect hoses and connections for leaks.
If coolant is found in the engine oil, the head gasket may need replacement:
- Remove the intake manifold and cylinder head.
- Replace the head gasket.
- Reinstall the cylinder head and intake manifold, torquing to specifications.
