A noisy valve lifter can be a sign of insufficient oil flow or low oil pressure, which may cause the lifter to not function properly. The noise often diminishes as the engine warms up and oil circulates more effectively, reducing friction and allowing the lifter to operate smoothly. However, if the noise persists or occurs frequently, it could indicate a more significant issue that may require professional inspection. Regular maintenance and using the correct oil viscosity can help prevent lifter noise.
