why does my Honda Accord 10th Generation (2018-2022) have a clicking sound from the engine

Solution

1. Preparation

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

2. Inspect and Replace Engine Oil

• Sub-steps:
  1. Remove the oil drain plug using a socket wrench and drain the oil into a suitable container.
  2. Change the oil filter if necessary.
  3. Replace the drain plug and tighten to the manufacturer's torque specification (typically around 20 lb-ft).
  4. Refill the engine with the recommended oil type (usually 0W-20 for Honda) through the oil filler cap.
• Tools Required: Socket set, oil filter wrench, oil catch pan.

3. Check Valve Clearance

• Sub-steps:
  1. Remove the valve cover by unscrewing the bolts using a socket wrench.
  2. Measure the valve clearance with a feeler gauge, comparing it to the specifications in the service manual.
  3. Adjust the clearance if out of specification by replacing shims or adjusting the rocker arms as necessary.
  4. Reinstall the valve cover with a new gasket.
• Tools Required: Socket set, feeler gauge, torque wrench.

4. Inspect and Replace Timing Chain/Belt

• Sub-steps:
  1. Remove any components obstructing access to the timing chain/belt (such as the front engine cover).
  2. Check for wear or damage on the chain/belt and tensioners.
  3. If worn, replace with a new timing chain/belt kit according to the manufacturer's specifications.
  4. Reassemble all components and ensure proper alignment of timing marks.
• Tools Required: Torque wrench, socket set, timing tool set.
