Figure 2: Typically shaped oil seal and component nomenclature
- The engine valve cover gasket set is an essential component in the proper functioning of a vehicle's engine. This set of gaskets is responsible for sealing the engine valve cover to prevent oil leaks and maintain proper pressure within the engine. Without a functioning valve cover gasket set, the engine can experience oil leaks, loss of pressure, and ultimately, serious damage.
70: The seal suits the housing bore diameter of ϕ70 mm.
As shown in Figure 1, sealing devices come in two types: contact and non-contact.
Oil seals are among the major contact type sealing devices.
