Disconnect the negative terminal of the battery for safety.

2. Replace Worn Piston Rings

Remove the engine cover and any components obstructing access to the cylinder head.
Drain engine oil and remove the oil pan.
Remove the cylinder head to access the pistons.
Remove the piston from the cylinder and inspect the rings for wear or damage.
Replace the piston rings with new ones, ensuring proper orientation.
Reassemble the engine components in reverse order, ensuring all bolts are torqued to the manufacturer specifications.

3. Replace Valve Seals

Use a valve spring compressor tool to remove the valve springs from the cylinder head.
Replace worn valve seals with new seals.
Reassemble the valve springs and ensure they are seated correctly.

4. Clean or Replace PCV System Components

Remove the PCV valve from the engine.
Inspect for blockages; clean or replace as necessary.
