Jeep Grand Cherokee clicking noise from engine due to valve rocker bearings failure and possible cam shaft damage on Jeep Grand Cherokee

Some Jeep Grand Cherokee owners report experiencing a clicking noise in the engine, which may be attributed to worn out engine bearings causing metal-to-metal contact between the crankshaft and connecting rod or the camshaft and rocker's arm. This issue can manifest as a tapping, clicking, or ticking sound, and may also resemble the noise from a worn or loose engine valve train component, such as a valve lifter, particularly in colder temperatures. If the clicking noise is engine-related, it is crucial for owners to address the worn bearings and potential camshaft damage promptly to prevent further complications and maintain vehicle performance.
