Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Engine Oil

Tools Required: Oil filter wrench, oil pan
Remove the oil fill cap and check for proper oil level.
If low, add the recommended oil grade as per manufacturer specifications.
If oil is dirty or contaminated, proceed to change the oil and filter.
- Drain the old oil using an oil pan.
- Replace the oil filter using an oil filter wrench.
- Refill with new oil.

3. Inspect Engine Components

Tools Required: Socket set, torque wrench
Remove any necessary engine covers to access the timing chain/belt and valve covers.
Visually inspect the timing chain/belt for signs of wear, stretching, or misalignment.
Inspect the valve lifters and rocker arms for wear or damage.
If any damaged components are found, replace them as necessary.

4. Adjust Valve Clearance

Tools Required: Feeler gauge, wrench set
Remove the valve cover to access the valve train.
Use the feeler gauge to check valve clearances.
Adjust as necessary to manufacturer specifications.

5. Reassemble and Test

Reinstall the valve cover and any other components removed.
Reconnect the negative battery terminal.
Start the engine and monitor for any abnormal noises.
Take the vehicle for a test drive to ensure the ticking noise has been resolved.
