Some Chevrolet Tahoe owners report experiencing issues related to a collapsed lifter on cylinder 1, which can lead to excessive valve train lash, resulting in noise and potential engine damage. Symptoms of this problem include a loud ticking noise from the engine, low compression in one or more cylinders, misfires, rough running, and difficulties with stalling or hard starting. Owners emphasize the importance of thoroughly inspecting the affected cylinder, as a stuck or collapsed lifter can significantly affect smooth operation. In many cases, replacing all lifters and pushrods in the affected bank may be necessary to resolve the issue effectively.
