What Causes Engine Ticking Noise After Timing Belt Replacement?

[LeFrank]

Engine ticking noise after timing belt replacement can be caused by excessive tension in the timing belt, damaged tensioner pulley, abnormal valve clearance, or misaligned/loose timing gears. If the car experiences weak throttle response, it indicates aged timing belt; severe engine vibration at idle suggests serious timing belt damage requiring immediate replacement. Timing belt replacement considerations: 1. Replacement intervals vary by brand and mileage - typically every 60,000-80,000 km; 2. Not all vehicles require timing belt replacement - some models never need it; 3. Consider both mileage and vehicle age - generally replace every 3 years; 4. Always choose authorized 4S shops and use genuine parts for safer and longer-lasting performance.
