3. Compress the valve springs with a valve spring compressor tool.
4. Carefully remove the old valve seals and replace them with new ones.
5. Reassemble the valve springs and valve cover using the specified torque (usually around 10-15 Nm).

3. Replace Piston Rings (if needed)

Steps:
1. Remove the engine from the vehicle, following manufacturer guidelines.
2. Remove the oil pan and cylinder head.
3. Remove the pistons from the engine block.
4. Replace the old piston rings with new ones, ensuring proper orientation.
