Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Change Engine Oil and Filter

Sub-steps:
1. Place an oil drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench and allow old oil to drain completely.
3. Replace the oil drain plug and torque it to 30 ft-lbs.
4. Remove the old oil filter using an oil filter wrench.
5. Apply a thin layer of oil to the rubber gasket of the new oil filter and install it hand-tight.
6. Refill the engine with the appropriate type and amount of fresh oil (5W-20 or 0W-20 as specified in the owner's manual).

3. Replace PCV Valve

Sub-steps:
1. Locate the PCV valve (typically found on the valve cover).
2. Disconnect the vacuum hose attached to the PCV valve.
3. Remove the old PCV valve by twisting it counterclockwise.
4. Install the new PCV valve and reconnect the vacuum hose.

4. Inspect and Replace Piston Rings (if necessary)

Sub-steps:
1. Remove the engine from the vehicle if required for access.
2. Remove the cylinder head by loosening the head bolts in the proper sequence and torque specification.
3. Remove the pistons and inspect the rings for wear or damage.
4. Replace the piston rings and reassemble the engine in reverse order, ensuring all components are torqued to specification.
