Can a bad harmonic balance cause knocking?

Yes, a bad harmonic balance can cause knocking in an engine. Harmonic balance refers to the distribution of forces and vibrations within the engine, and if it's not properly balanced, it can lead to excessive vibrations. These vibrations can result in knocking or pinging, as they may cause the engine components to misalign or operate inefficiently. Proper maintenance and calibration of the harmonic balancer are essential to prevent such issues.

Can a bad camshaft sensor make a engine knock?

Yes, a bad camshaft sensor can indirectly lead to engine knocking. The camshaft sensor plays a crucial role in the engine's timing and fuel delivery. If it malfunctions, it can cause improper fuel-air mixture or timing issues, which may result in knocking or pinging sounds as the engine misfires or operates inefficiently. However, knocking can also stem from other issues, so a thorough diagnosis is essential.
