The first step is to remove the engine from the car. This can be a complex and time-consuming task, so it is important to consult your car’s service manual for specific instructions.

3. Disassemble the engine

Once the engine is removed, you will need to disassemble it in order to access the pistons and rings. This involves removing the cylinder head, the oil pan, and the timing chain cover.

4. Remove the old engine rings

Using a piston ring compressor, compress the old engine rings and remove them from the pistons. Be careful not to damage the pistons or the cylinder walls.

Using a ring expander, expand the new engine rings and install them on the pistons. Make sure that the rings are installed in the correct order and that the gaps are properly aligned.

6. Torque the engine

Once the new engine rings are installed, torque the engine to the specified torque value. This will help to ensure a proper seal.

7. Reassemble the engine

Reassemble the engine in the reverse order of disassembly. Be careful not to overtighten any of the bolts or nuts.

Install the engine back into the car. Connect all of the necessary fluids and wires.
