Head Gasket Set Intake Exhaust Valves Fit 06-11 Honda Civic 1.8 SOHC R18A1 R18A4. The main function of an engine valve is to open and close rapidly. This allows the air and fuel charge to enter the combustion chamber and after ignition, the exhaust valve allows the waste gases to flow out into the exhaust system. Each cylinder has at least one intake and one exhaust valve. The head gasket is the key component of the engine. It is compressed between the engine block and the cylinder head. The head gasket seals in the internal combustion process to make sure maximum compression is achieved and also keeps coolant and oil from mixing together as the two fluids travel from the engine block to the cylinder head. The cylinder head bolts hold the cylinder head and cylinder head gasket in place and ensure that the cylinder head will continue to hold up despite the tremendous amounts of pressure in the combustion chamber. Therefore the cylinder head bolts, cylinder head gasket, and intake exhaust valves are an important part of your engine. They should always be in perfect condition and should be maintained properly. So, if you notice that this part is showing signs of excessive wear, have them replaced immediately. Be sure to have your worn out parts replace with our aftermarket replacement parts set as soon as they start to give you trouble.
