5 Symptoms of a Cracked Cylinder Head
1. A cylinder head is the “top end” of the engine. It mates to the engine block to seal off the combustion chamber, which is where the engine burns fuel to make power.
Cylinder heads also house the valves that direct airflow. Intake valves draw in fresh air, combustion occurs, then exhaust valves allow the burnt air fuel mixture to exit the combustion chamber. An internal combustion engine is basically just a fancy air pump.
Under extreme conditions, a cylinder head can actually crack. A cracked cylinder head may yield similar symptoms to a blown head gasket or a cracked block, but is more expensive to fix than a blown head gasket. The solution is usually to buy a new cylinder head.
1. Air in the Cooling System

Air in the cooling system may allow hot spots to form, where one part of the engine is much hotter than the portion measured by the temperature sensor. This happens because air cannot transfer heat as effectively as a liquid can.
If air is trapped in one spot away from the coolant temperature sensor, the temperature sensor may not pick up the hot spot. You may not know your car is running hot until damage is already done.
Additionally, an air leak in the cooling system may reduce the pressure in the cooling system. Liquid coolant is more likely to boil at a lower pressure.
Question: how much does it cost to replace a cylinder head gasket?
Answer: the amount depends on your locality and type of car or engine. Head gasket replacement cost can go up to $1000. While the price of the gasket may not be that high, it takes a lot of time to replace. You are dismantling almost half of the engine, which makes the process labor-intensive. Head gasket repair costs even more.
