Head gasket of car's engine is an important component of internal combustion engine and it is located between engine block and automotive cylinder heads. It is considered as most critical sealing application in the engine, as its job is to seal the cylinders ensuring maximum compression and avoiding leakage of coolant and oil on the cylinders. It also keeps coolant and oil from mixing as the two fluids travel from engine block to cylinder head. Head gasket also works to seal hot combustion gases and coolant which can be anywhere from cold temperatures to normal operating temperatures of your engine. It is quite unusual for the head gaskets to develop leaks because of large surface area and range of temperatures of engine block.
A vehicle’s engine is made to work in extreme conditions with intense heat. This heat may cause the cylinder head or engine block to expand which in turn will result in a blown head gasket.
There replacement is costly because repairing of head gasket means doing operations of removing engine’s head. You cannot see much of the head gasket on the vehicle without disassembling engine.

If you are inspecting your car’s exhaust pipes for signs of white smoke, make sure your car is fully warmed up during warm part of the day. A cold engine will produce small amount of vapor which will look like white smoke coming out of exhaust pipe.
Bubbling in the Radiator
High pressure built during combustion process in the cylinder can push the exhaust gases past the head gasket into the engine cooling system. The trapped exhaust gases will be circulated to the car’s radiator via engine. If the head gasket is having a leak, there is a high possibility of emission of air bubbles out of the radiator.
In this situation it is not wise to remove the radiator cap immediately as the engine cooling system is still under pressure. You can also check the presence of air bubbles in coolant overflow tank or you can rev your engine many times. If air bubbles are found, then no time should be wasted on thinking for replacement, just do it.
Overheating of the Engine
Engine overheating is one of the first common sign pointing towards a blown head gasket. During overheating, metal of the engine block and head expands beyond limits. Any damage to head gasket will lead to loss of compression by the engine eventually causing the engine to overheat. If you experience overheating, it is advised to shut the engine down and call for the professionals before damaging other engine components along with the gasket. It is advised to stop the car when car's engine overheats.
Milky White coloration in the oil
After the engine is turned off, the coolant that is still left inside enters engine oil through piston rings. You can check the vehicle’s oil cap to detect this issue. A white milky substance is formed when the coolant mixes with the oil. If the milky ring is found around the cap, then the oil is probably contaminated by the coolant. In this situation you may have to flushout the contaminated automotive oil along with the replacement of head gasket.
