Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the engine.

2. Inspect and Tighten Components

Sub-steps:
- Use a socket set to check and tighten all accessible bolts and screws in the engine bay, particularly around the valve cover, intake manifold, and exhaust system.
- Inspect heat shields and brackets for any signs of wear or looseness, and tighten them as necessary.

3. Change Engine Oil and Filter

Sub-steps:
- Place an oil drain pan below the oil pan and remove the oil drain plug using a wrench. Allow old oil to drain completely.
- Replace the oil filter using an oil filter wrench, ensuring the rubber O-ring from the old filter is removed.
- Reinstall the drain plug and refill the engine with the manufacturer's recommended oil type and quantity.

4. Replace Timing Chain/Belt (if necessary)

Sub-steps:
- Remove any components obstructing access to the timing chain/belt cover, such as the accessory drive belts.
- Remove the timing cover bolts and gently pry off the timing cover.
- Align timing marks, remove the old timing chain/belt, and install the new one, ensuring proper tension and alignment.
- Reinstall the timing cover and any components removed earlier, torqueing bolts to manufacturer specifications.

5. Clear Codes and Reconnect Battery

Sub-steps:
- Use the OBD-II scanner to clear any error codes stored in the vehicle's computer.
- Reconnect the negative battery terminal.
