Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, compression tester, oil catch pan, oil filter wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during repairs.

2. Addressing PCV System Issues

Locate the PCV valve on the engine.
Remove the PCV valve from its housing.
Inspect the valve for clogs and ensure it operates freely.
If clogged, clean it with intake cleaner or replace it if necessary.
Reinstall the PCV valve securely.

3. Engine Compression Test

Remove the spark plugs to access the cylinder head.
Attach the compression tester to the first cylinder.
Crank the engine and record the compression reading.
Repeat for all cylinders and compare results to manufacturer specifications.
If compression is low, consider replacing piston rings or valve seals.

4. Replace Valve Seals (if necessary)

Remove the valve cover by loosening bolts with the socket set.
Carefully lift the valve cover away and check for any debris.
Remove the rocker arms and springs to access the valve seals.
Replace old valve seals with new ones using a seal installer tool.
Reassemble the rocker arms and valve cover, ensuring proper torque specifications.

5. Adding Oil Stop Leak (if applicable)

If minor leaks are present, consider adding a commercial oil stop leak product.
Follow the instructions on the product for the correct amount to add.
