Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Replace PCV Valve

Locate the PCV valve on the engine.
Remove the PCV valve using pliers or a socket set.
Inspect the old PCV valve for clogs or damage.
Install the new PCV valve, ensuring it is seated properly.

3. Perform Compression Test

Remove spark plugs using a spark plug socket.
Connect the compression tester to the first cylinder.
Crank the engine and record the compression reading.
Repeat for all cylinders; compare results to manufacturer specifications.
If readings are low, further investigation into piston rings or cylinder walls may be necessary.

4. Address Oil Leaks

Identify the source of any visible oil leaks.
Replace gaskets or seals as needed using an appropriate gasket scraper.
Torque bolts to manufacturer specifications when reinstalling components.

5. Engine Oil Change

Place an oil drain pan under the oil pan.
Remove the drain plug with a socket set and allow oil to drain completely.
Replace the oil filter using an oil filter wrench.
Install the drain plug and torque to specification.
Refill the engine with the manufacturer-recommended oil type and quantity.
