What are the symptoms of a cracked cylinder head?
Symptoms will vary based on the location and severity of the crack. A crack in the combustion chamber often results in an overheating issue and sometimes a misfire. If a misfire is present it may be more pronounced on startup and after sitting for a while. If the crack is in the head bolt or valve cover area, a slow loss of engine coolant is a common symptom.
