Gaskets and seals have always been playing a crucial role in the operation of any internal combustion engine, be it an automotive, marine, or railway powerplant. Providing the necessary sealing, gaskets enable the motor to run without leaks, but when they get faulty, these parts become a frequent reason for various engine malfunctions. As a result of air leaks, you get the wrong air-fuel mixture and affected performance. Oil leaks lead to high oil consumption and, if too much oil gets into the cylinders, an excessive buildup of carbon deposits in the combustion chamber and exhaust system.
In order to keep the seals in good condition, make sure the engine doesn't overheat and replace them when they get leaky. Many of them are not reusable, which means they need replacement every time you remove such a seal or a corresponding assembly. The material also matters, especially when it comes to crankshaft or valve seals; the finest options are made of PTFE or FKM, which are known for their high resistance to heat and chemicals. In our online store, you will find a wide range of crankshaft and other kinds of seals which are sold alongside timing covers and gaskets related to the engine block. Besides, you can select from welch plugs more peculiar to older engine designs.
