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 battery terminal to prevent electrical shorts.

2. Replace Piston Rings (if necessary)

Drain Engine Oil:
- Use a socket set to remove the oil drain plug.
- Allow oil to completely drain into a suitable container.
Remove Engine Components:
- Disconnect the intake manifold and throttle body.
- Remove the cylinder head following the manufacturer's torque specifications.
- Take off the oil pan by removing bolts with a socket set.
Remove Old Piston Rings:
- Carefully remove the pistons from the engine block.
- Use a piston ring compressor to remove the old rings, being cautious not to damage the pistons.
Install New Piston Rings:
- Apply oil to the new piston rings and install them using the piston ring compressor.
- Reinstall the pistons into the cylinder bores.

3. Replace Valve Seals (if necessary)

Remove Cylinder Head:
- If not previously done, remove the cylinder head to access the valve seals.
Replace Valve Seals:
- Carefully remove old valve seals using a seal puller tool.
- Install new valve seals ensuring they are seated properly.
Reassemble Engine:
- Reinstall the cylinder head, intake manifold, and oil pan according to torque specifications.
- Refill with fresh engine oil and reconnect the battery.
