A head gasket is a gasket that sits between the engine block and cylinder head(s) in an internal combustion engine.The gasket itself is a mechanical seal that prevents leaks between two things joined under compression by filling the space between them.  It works similarly to a washer on a bolt.  By preventing leaks, you ensure the best compression and you keep coolant from leaking into the engine.  The head gasket in the engine has to take both hot and cold temperatures, back and forth, over and over.  Cracks and leaks are bound to happen.  The head gasket has a tough job and is the weakest link of the chain of parts that keep the combustion engine moving, so it’s more likely to fail than other parts.
 
If a head gasket leaks or blows, it’s usually not just one event that leads up to it.  Either could happen during normal driving.  The heat of the engine can gradually wear the gasket down with no major problems ever occurring.  Until it leaks or blows, however, it’s hard to know if the head gasket is running out of time.  It’s not something you can see looking at the engine; it’s way the heck in there and can’t be accessed without some major disassembly.  Other things may signal your head gasket’s cry for help.  You may see coolant leak from below the exhaust, you may be losing coolant with no visible leak or noticing  bubbles in the radiator or coolant overflow tank.  The engine may smoke (this will be white smoke; if not, keep looking because your engine has another problem), the exhaust may smell sweet or the oil may look like a rancid milkshake.
 

So what to do if you have a head gasket problem?  It’s not a cheap repair.  Let’s face it, this thing sits inside the engine.  If it’s a minor leak, you may be able to seal it with products available like Blue Devil or K-Seal.  Talk to a mechanic you trust to determine whether this will do the trick.  Using these products could be as simple as pouring it in and letting it move through the works as you drive or may require a drain and flush of the cooling system—either option is far cheaper than replacing the gasket itself.  Be forewarned that products like Blue Devil are meant to be permanent.  Speaking from personal experience, once it’s sealed, there’s no going back or getting it out or working around it.  That’s generally the idea, but sometimes folks look at it as a temporary patch.

Blown Manifold
The exhaust manifold gasket helps seal the union between the exhaust manifold and the side of the engine’s cylinder head. A blown exhaust gasket often protrudes from the gap between the exhaust manifold and the cylinder head.
Determining if an exhaust manifold gasket has failed is easy to do. First; SIGHT: A blown exhaust gasket often protrudes from the gap between the exhaust manifold and the cylinder head. 

Visually examine the area where the manifold and head meet, if the engine is a V-6 or V-8, compare both sides. Look for pieces of gasket that are protruding far more than the rest which will indicate the point of failure other visual sign is sooty exhaust which will stain the side of the cylinder head or manifold. SOUND: Exhaust gas and noise are expelled from the engine at a high velocity, down through the exhaust manifold and into exhaust pipes, where they pass through the catalytic converter and muffler before exiting from the tail. The event your manifold gasket is blown, the exhaust gas will escape at the seal between the manifold and cylinder head, resulting in a loud bang or pop noise each time that cylinder fires. SCENT: if strong exhaust odor is present in the engine area, inspect the exhaust gaskets to see if one or more has failed and is now allowing the untreated exhaust fumes to escape into the engine well. A cracked or broken exhaust manifold is most often caused by one of two things. The first reason is heat cycles and/or age. 

Over time, the manifolds just can't take the heat anymore and cracks begin to form in them. The second common reason for exhaust manifold failure is because of broken exhaust system hangers. In your Yearly emissions inspections, you will find that having a cracked exhaust manifold will instantly get you a rejection sticker. That's because when you have a hole in the exhaust system, it throws off the oxygen sensor readings, and will cause your vehicle to run inefficiently. You could also lose a few miles per gallon. Replacing an exhaust manifold will be a different procedure for each vehicle, so grabbing a service manual is a great start
