What does a cracked head sound like?
If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced. This loss of compression results in a rough running engine and a notable reduction in engine power. This sort of failure typically is accompanied by a sound like an exhaust leak.

What Is a Cylinder Head?
A cylinder head sits on top of the engine block and covers its cylinders, thus creating the combustion chamber. The cylinder head creates the space for the passages that feed air and fuel to the cylinders, and is sealed in place by the head gasket.
Could Other Parts of My Engine Be Affected?
Your cylinder head isn’t the only part of your engine that might be suffering. Select an engine part in the interactive diagram below to explore your engine and the important components that keep everything ticking over.

The most common reason for cylinder head failure is overheating caused by coolant loss, head gasket failure or restricted flow of coolant. In extreme cases a cracked or damaged cylinder head can result in terminal damage to the entire engine.
What is the purpose of the intake manifold?
The intake manifold feeds air into the head, where it is combusted with fuel to produce exhaust gases, which are expelled through the exhaust manifold. It’s important that the intake and exhaust valves, which allow the entry and exit of relevant gases, open and close at the correct times to keep the engine running smoothly.
What is warping in cylinder heads?
Warping is a particular problem for cylinder heads made of aluminium. Different engines have different levels of tolerance for cylinder head warping – some can withstand a high amount of warping while still working effectively.
What is the first step in cylinder head repair?
One of the most important first steps in cylinder head repair is determining what piece is damaged, as this could mean the difference between a simple, decisive repair and a problem going unnoticed, only to require even more costly repairs when that problem worsens.
What is the cylinder head?
The cylinder head is a vital part of many internal combustion engines. Along with a head gasket and rubber grommets, it seals the cylinders of the engine, ensuring its fuel intake, combustion, cooling and lubrication are all in working order.
How is the cost of a head determined?
The cost is usually determined by the amount of labor the job requires, whether the head needed full replacement or a simple repair, as well as what materials the head is built from (iron is older, and tends to be more expensive to work with than the more modern aluminum due to scarcity of parts).

You might find engine coolant or engine oil dripping onto the ground. That’s the case when the cylinder head cracks externally, and it depends where the head cracks. You might have a Check Engine light and the engine runs rough.
What is the cylinder head?
The cylinder head contains valves which operate the intake of air and fuel, as well as valves that release exhaust gases from the combustion chamber. A camshaft also works its way into the cylinder head, usually on the top. There might be more than one too, for engines with DOHC, or dual overhead cams. The camshaft rotates when the engine is ...
Why does my engine not run well?
The cylinder head can crack across a couple valves or between cylinders. When that happens, the engine has lower compression and won’t run very well at all.

What is the camshaft gasket?
The camshaft rotates when the engine is running, timed perfectly with the crankshaft so the engine runs smoothly. Then there are the gaskets. On the top is a valve cover gasket, preventing oil from spraying all over the place. Under the cylinder head where it meets the engine block is a cylinder head gasket.
What Causes a Cracked Cylinder Head?
Internal combustion engines heat up very quickly. As the name implies, they are designed to contain small, controlled explosions.
What happens if the thermostat is stuck closed?
If the thermostat is stuck closed, your engine will overheat pretty easily. The hot coolant has nowhere to go to cool off. In a pinch, some engines allow you to use the heater as a tiny radiator. The effectiveness of this method depends on the size of the heater core and how the cooling system is routed.
How does a thermostat work?
A thermostat blocks off coolant from the radiator until the coolant in the engine reaches the target temperature. Once the target temperature is reached, the thermostat opens to allow coolant at ambient temperature to enter the engine, cooling it until the thermostat is cold enough to close. The cycle continues as the engine runs.
What happens if your cylinder head is cracked?
If the cylinder head is severely cracked, then you’ll probably have coolant leaking out of it in addition to oil. This will cause your engine to overheat, which your car will warn you about on your dashboard. Sometimes coolant leaks are internal. Internal leaks may leak into the oil passages or the combustion chamber.
