Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Valve Seals

Sub-steps:
- Remove the valve cover by loosening the bolts with a socket set.
- Carefully lift the valve cover off and inspect the old valve seals for wear.
- Use a seal puller to remove the old valve seals from the valve guides.
- Apply a small amount of engine oil to the new valve seals and install them onto the valve guides.
- Reinstall the valve cover with a new gasket, tightening bolts to the manufacturer specified torque.

3. Replace Piston Rings (if necessary)

Sub-steps:
- Remove the engine from the vehicle if access to the pistons is required.
- Remove the oil pan and connecting rod caps to access the pistons.
- Use a piston ring compressor to remove the old piston rings from the pistons.
- Install new piston rings ensuring they are staggered properly.
- Reassemble the engine components in reverse order of disassembly.
