Sub-steps:
1. Remove the engine cover using a socket set.
2. Disconnect the necessary components (e.g., air intake, wiring harnesses) to access the valve cover.
3. Remove the valve cover bolts and lift the cover off.
4. Inspect the valve seals for wear or damage.
5. Use a seal puller to remove the old valve seals.
6. Lubricate the new valve seals with engine oil and install them.
7. Reassemble the valve cover with a new gasket and torque bolts to factory specifications.

3. Replace Piston Rings (if necessary)

Sub-steps:
1. Remove the engine from the vehicle following standard procedures (drain fluids, disconnect wiring).
2. Remove the oil pan and cylinder head to access the piston assembly.
3. Remove the pistons from the engine block.
4. Replace the old piston rings with new ones, ensuring proper orientation.
5. Reassemble the engine components in reverse order, following torque specifications.

4. Check and Clean PCV System

Sub-steps:
1. Locate the PCV valve and remove it from the engine.
2. Inspect the valve for blockages or damage.
