The engine's combustion takes place inside the engine cylinder. The cylinder head, together with the head gasket, seals off the combustion chamber. This cylinder head is the key to controlling airflow in and out of the cylinder and is very important for the internal combustion process to work effectively. The cylinder heads are usually designed with aluminum. The head is the hottest part of the engine, and aluminum is an excellent thermal conductor. The cylinder head design makes it fragile and could crack if the engine temperature is too hot. While the cracks could only be detected through physical inspection, specific indicators of the problem include overheating and engine misfiring. Leaving the problem unfixed could spiral into a much larger problem. If you leave the symptoms unattended, the cracked head could cause irreparable engine damage. Ke [...]
