2. Inspect and Replace PCV Valve

Sub-steps:
- Locate the PCV valve; it is usually found on the valve cover.
- Remove the PCV valve by twisting it counterclockwise and pulling it out.
- Inspect the old PCV valve for clogs or damage; replace it if necessary.
- Install the new PCV valve by pushing it in and twisting it clockwise until secure.
Tools Required: Pliers, socket set.

3. Repair Oil Leaks

Sub-steps:
- Identify the source of oil leaks using the inspection performed.
- Clean the area around the leaks with engine degreaser.
- Replace worn or damaged gaskets and seals (e.g., valve cover gasket, oil pan gasket).
Tools Required: Socket set, torque wrench, gasket scraper.

4. Replace Engine Oil and Filter

Sub-steps:
- Drain the old engine oil using an oil drain pan.
- Replace the oil filter using an oil filter wrench.
- Refill the engine with the manufacturer-recommended oil type and quantity.
Tools Required: Oil filter wrench, oil drain pan, funnel.

5. Conduct Engine Tests

Sub-steps:
- Perform a compression test and leak-down test to verify engine integrity.
- If results are poor, consider further disassembly for piston ring replacement or valve seal replacement.
Tools Required: Compression tester, leak-down tester.
