Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Change Engine Oil and Filter

Sub-steps:
1. Place an oil drain pan underneath the oil pan.
2. Remove the oil drain plug with a socket wrench and allow the old oil to drain completely.
3. Replace the oil drain plug and torque it to the manufacturer’s specification (typically around 20-25 ft-lbs).
4. Remove the old oil filter using an oil filter wrench.
5. Lubricate the rubber gasket on the new oil filter with fresh oil and install it.
6. Fill the engine with the recommended oil type and quantity (5W-20 or as specified in the owner's manual).

3. Inspect and Adjust Valve Lifters

Sub-steps:
1. Remove the engine cover by unscrewing the retaining bolts.
2. Inspect the valve lifters for wear; replace if they are worn or damaged.
3. Adjust the valve clearance to the specifications provided in the service manual (typically using a feeler gauge).
4. Reinstall the engine cover and torque the bolts to the specified value.

4. Check Timing Chain/Belt

Sub-steps:
1. Remove any components obstructing access to the timing cover.
2. Inspect the timing chain/belt for signs of wear or stretching.
3. If worn, replace the timing chain/belt and tensioner according to the manufacturer's instructions.
4. Reassemble any components removed during this process.
