Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Fix Oil Leaks

Tools Required: Socket set, torque wrench, oil catch pan.
Inspect gaskets, seals, and oil pan for leaks.
Replace any faulty gaskets or seals as necessary.
- Sub-steps:
  - Remove the old gasket/seal using a scraper.
  - Clean the mating surfaces with a solvent.
  - Apply a new gasket or sealant as recommended by the manufacturer.
  - Reassemble and torque to manufacturer specifications.

3. Address PCV System

Tools Required: Screwdrivers, pliers.
Inspect and clean or replace the PCV valve if clogged.
- Sub-steps:
  - Disconnect the PCV hose.
  - Remove the PCV valve from its position.
  - Clean with solvent or replace with a new valve.
  - Reconnect the PCV hose securely.

4. Compression Test

Tools Required: Compression gauge.
Perform a compression test to identify worn piston rings or valves.
- Sub-steps:
  - Remove spark plugs to allow for accurate readings.
  - Insert the compression gauge into the spark plug hole.
  - Crank the engine to take a reading.
  - Compare readings across all cylinders; low readings may indicate the need for further repairs.

5. Oil Change and Filter Replacement

Tools Required: Oil filter wrench, socket set, oil catch pan.
Change the oil and filter to ensure proper lubrication.
- Sub-steps:
  - Drain the old oil into a pan.
  - Replace the oil filter, ensuring the old O-ring is removed.
  - Fill with the recommended type and amount of new oil.
