how to fix Honda CR-V Fifth Generation (2017-2022) timing chain noise

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, torque wrench, stethoscope, engine oil, timing chain tensioner tool (if needed).
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Replace Timing Chain Tensioner

1. Remove Engine Covers:
   • Use a socket set to remove any plastic engine covers obstructing access to the timing chain.
2. Drain Engine Oil:
   • Place a drain pan under the oil pan, remove the drain plug, and allow the oil to fully drain.
3. Remove Timing Chain Tensioner:
   • Locate the timing chain tensioner. Unbolt it carefully using a socket wrench.
   • If using a tensioner tool, compress the tensioner before removal.
4. Install New Timing Chain Tensioner:
   • Position the new tensioner in place and torque the bolts to the manufacturer's specifications (usually around 10-15 ft-lbs).
   • Release the tensioner if it’s equipped with a locking mechanism.
5. Reassemble Engine Components:
   • Replace the timing chain cover and any other components removed.
   • Fill the engine with new oil to the appropriate level.

3. Check and Replace Timing Chain Guides (if necessary)

1. Access Timing Chain:
   • Remove the necessary components to gain access to the timing chain and guides.
2. Inspect Timing Chain and Guides:
   • Check for wear on the chain and guides. Replace any damaged components.
3. Reassemble:
