There might not be any hint of it, but there's a lot of pressure and compression going on inside a running vehicle. Some engine and other automotive components need a mechanical seal that can handle the heat-cool cycles and low-high compression loads while filling in the gaps between parts and allowing their surfaces to mate. They lock in oil, coolant, fuel, air, and compression, which are all crucial to smooth vehicle operation. This seal goes by the name .gasket..
Gaskets are manufactured from paper, rubber, metal, plastic polymer, felt, cork, fiberglass, and other materials. They are used in various parts of the vehicle. Different automotive gaskets include:
Water pump gaskets
Water pump gaskets help seal in coolant or water that's sprayed by the pump from the radiator and into the engine. Water or coolant that circulates through the engine block and back to the radiator keeps the engine operating within an optimum temperature range.
Differential gaskets are attached to the axle used in the transmission. They keep in the gear oil while keeping out dirt and other impurities from the axle tube. With these mechanical seals, transmission parts are able to function well without incurring any damage.
Transmission gaskets are used to forge a pressure-tight connection between transmission parts. Made flexible, they help prevent leaks in servos, accumulators, and clutch packs and also keep fluids from escaping to the outside of the trans axle case.
Oil pan gaskets
Oil pan gaskets are usually found at the crankcase's bottom part. They keep oil used to lubricate the engine from leaking out. Traces of oil somewhere around the parameter of the oil pan can be caused by a broken gasket.
Fuel supply gaskets
Fuel supply gaskets help seal in the needed pressure by the engine, preventing fluid leaks in the process. They are used in-between static surfaces.
Cooling system gaskets
Cooling system gaskets are made of soft sheet metal and other materials such as steel, graphite, silicone, polymeric resin, copper, fiber-based composite, and stainless steel. These seals are used on pipe joints and other joined components in the system to keep liquid or gas from escaping.
Valve cover gaskets
Valve cover gaskets maintain the right amount of pressure needed between the valve cover and the engine block. These mechanical seals not only lock in the needed pressure but also keep oil from leaking through.
Different types of engine gasket
Engine gaskets seal different metal parts in the block to keep fluids like oil and water or coolant from leaking out and from intermixing with each other as these can cause engine failure. These seals also help lock in the much-needed compression for optimum vehicle performance. One good example of these mechanical seals is the head gasket. It is positioned between the cylinder head and engine block. By sealing the cylinders, maximized compression is achieved. It also keeps coolant and engine oil from seeping into the cylinders.
Though gaskets are built to withstand a severe environment, some may crack or blow after some time because of overheating, wrong installation, faulty calibration, and prolonged wear due to old age and excessive mileage. When any gasket fails, it needs to be replaced before you get into trouble with leaks and have to deal with a vehicle that runs poorly.
