The oblique sealing surface defines an oblique angle with a centerline of the engine component. The sealing system includes a seal housing and a seal ring. The seal housing is annular and includes a groove that is defined by a first sidewall, a second sidewall, and an end wall connecting the first sidewall and the second sidewall. The seal ring is positioned at least partially within the groove in the seal housing. The seal ring defines a seal contact surface for forming a seal with the oblique sealing surface of the engine component.
