What are the common problems with the GS5 engine?

[OMaci]

Common problems with the GS5 engine include poor intake combustion lubrication during cold starts, abnormal exhaust valve noise, and engine noise after operation. Specific common issues are as follows: 1. Engine noise can be categorized into abnormal noise during cold starts, during rapid acceleration, and during idle conditions. 2. Abnormal noise from engine mounts caused by aging or loosening of the mounts. Engine mounts, also known as engine support mounts or engine brackets, are typically installed between the engine and the vehicle body, connecting the body and the engine to secure the engine in place. Their most important function is to provide buffering and vibration damping. Once the engine mounts age or become loose, engine vibrations will become significantly more pronounced.
