Chevrolet Silverado 1500 ticking and knocking sounds at startup with acceleration lag, suspecting lifter replacement on Chevrolet Silverado 1500

Some Chevrolet Silverado 1500 owners report experiencing ticking and knocking sounds at startup, along with acceleration lag. These issues may stem from a ticking lifter, which can make the engine sound as though it is struggling. Additionally, a stretched or worn-out timing chain may contribute to the ticking noise, particularly during acceleration. Some owners have also noted that an exhaust system leak can create a ticking or rattling sound during engine acceleration or deceleration. Furthermore, engine knock noises may occur during initial startup, although they often disappear shortly after. Acceleration lag may be linked to faulty fuel injectors, which can produce a ticking sound as they spray fuel into the cylinders. It is advisable for owners to consult a professional mechanic for diagnosis and to determine the best course of action regarding these potential issues.
