Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before starting work.

2. Check for External Leaks

Tools Required: Oil filter wrench, rags, flashlight
Inspect the oil pan, valve cover gaskets, and oil filter for leaks.
Clean any oil residue to ensure you can identify new leaks after repairs.

3. Replace Worn Components

If leaks are found:
- Valve Cover Gasket: Remove old gasket, clean surfaces, and install a new gasket with recommended torque (typically 10-15 ft-lbs).
- Oil Filter: Remove the old oil filter and replace it with a new one, ensuring to lubricate the rubber O-ring and tighten according to the manufacturer’s specification.

4. Address Internal Engine Issues

If compression tests indicate low pressure:
- Remove the cylinder head, inspect for worn piston rings, and replace if necessary.
- Use a torque wrench to ensure the cylinder head bolts are tightened to the manufacturer's specifications (refer to service manual for specific values).

5. Inspect and Replace PCV Valve

Tools Required: Pliers, new PCV valve
Locate the PCV valve (typically on the valve cover) and remove it using pliers.
Inspect for blockages, replace if necessary, and ensure the hose is clean and free of obstructions.

6. Refill Engine Oil

Refill the engine with the manufacturer-recommended oil type and viscosity (consult the owner’s manual).
Start the engine and check for leaks.
