The head gasket can be considered one of the most critical and crucial sealing operations in the whole automobile specifically in the engine. That is because it is primarily designed to seal the cylinders to make sure there is maximum compression to prevent leakage of coolant or engine oil into the cylinders. In an internal combustion engine, the head gasket sits between the engine block and the cylinder head. A good quality head gasket should be able to do its sealing job from installation until there is engine life. Car manufacturers have designed their head gaskets to be able to seal and restrict the coolant and oil and be leak-free for a long time that is if it does not encounter any problems.
One of the major problems that head gasket now encounter is the aluminum cylinder on cast iron block because it makes engines more difficult to seal. This is because the aluminum can expand faster when heated making them expand faster. The aluminum cylinder is more often used because it weighs less but because it expands fast due to heat the head gasket is not able to seal it properly. Thus, materials like molybdenum, Teflon and others are being used to prevent the gaskets from sticking to either surface and allowing the head to expand and contract without tearing the gasket apart. Applied to the gasket is raised silicon or fluoropolymer elastomer sealing beads to intensify the clamping pressure and boost the sealing ability of the gasket.
The head gasket is too important to just take for granted. Effect of a blown gasket could vary from compression loss to exhaust gases being pushed towards the cooling system. This can add on to the already heated engine and cause it to overheat and corrupt the anti freeze with the motor oil and amplifying engine wear. Because it is the task of the head gasket to seal and contain the coolant and oil, a blown one would mean loss of the necessary oil for lubrication. It would definitely cause more extensive engine damage due to overheating. Always look for signs that you are having problems with your head gasket. One way to check is by taking a look at the pressure gauge to measure the compression pressure and the pressure in the cooling system. Excessive coolant loss and oil mixed with coolant is monitored in the gauge and these are definite signs of head gasket problems.
