Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Worn Components

Inspect Engine Seals and Gaskets
- Remove any engine covers if necessary using a socket set.
- Check the condition of oil pan gaskets, valve cover gaskets, and any seals.
- Replace any worn or damaged seals/gaskets with OEM parts.
Replace PCV Valve
- Locate the PCV valve and disconnect the hose connected to it.
- Remove the PCV valve using pliers.
- Install the new PCV valve and reconnect the hose securely.

3. Engine Repair (if needed)

Replace Piston Rings (if compression/leak-down tests indicate wear)
- Remove the engine from the vehicle (follow manufacturer-specific guidelines).
- Disassemble the engine to access the piston assembly.
- Replace worn piston rings with new ones.
- Reassemble the engine following torque specifications for all components.

4. Refill Engine Oil

Add the manufacturer-recommended engine oil type to the engine.
Start the engine and let it run for a few minutes to ensure proper circulation.
Check for leaks and ensure the oil level is correct.
