Solution

1. Preparation

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

2. Addressing Oil Leaks

Tools Required: Socket set, torque wrench, oil catch pan, rags.
Identify the source of any visible leaks (e.g., valve cover gaskets, oil pan gasket).
Remove any components obstructing access to the leaking area.
Replace damaged gaskets or seals.
Reassemble components and torque to manufacturer specifications.

3. Replacing PCV Valve

Tools Required: Pliers, socket set.
Locate the PCV valve, usually found on the valve cover.
Disconnect the PCV hose and remove the old valve.
Install the new PCV valve and reconnect the hose.

4. Engine Oil Change

Tools Required: Oil filter wrench, socket set, funnel.
Drain the old oil using an oil catch pan, and remove the oil filter.
Replace with a new oil filter and refill with the manufacturer-recommended oil type and capacity.
Start the engine and check for leaks.

5. Compression Test (if necessary)

Tools Required: Compression tester.
Remove the spark plugs.
Insert the compression tester into each cylinder and crank the engine.
Record the compression readings for each cylinder and compare with specifications.
